# Introduction
Modern machine learning (ML) models learn high- dimensional embedding representations to capture the domain semantics and relationships in the train- ing data (Raghu et al., 2019). ML researchers and domain experts are increasingly using expressive embedding representations to interpret trained mod- els (Park et al., 2022), develop models for new domains (Lee et al., 2018) and modalities (Ben1
younes et al., 2019), as well as analyze and syn- thesize new datasets (Kern et al., 2016). However, it can be difficult to interpret and use embeddings in practice, as these high-dimensional representa- tions are often opaque, complex, and can contain unpredictable structures (Bolukbasi et al., 2016). Furthermore, analysts face scalability challenges as large datasets can require them to study millions of embeddings holistically (Tang et al., 2016).

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

specification of undesired behavior. Figure 1 illustrates our approach. The framework splits red- teaming into three steps: 1) exploring the range of behaviors the model can exhibit; 2) establishing a contextual definition and measurement for undesirable behaviors; and 3) exploiting the modelâs vulnerabilities using this measure and an automated adversarial prompting method. The final result is a dataset of diverse, labeled examples, a measurement (e.g., a classifier) for undesirable text, and a generation process for adversarial prompts. Overall, we make three contributions:
1. Framework: We provide a framework for automated red-teaming where the red team does not begin with access to a classifier for the target behavior and must produce one through interaction with the model.
2. Applications: We demonstrate that this is practical by red-teaming GPT-2-xl to produce toxic text and GPT-3-text-davinci-002 to output false text.
3. Methodology: We introduce a new technique to avoid mode collapse when using rein- forcement learning for automatic prompt generation.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

on long sequences [26] and token importance is concentrated in a local receptive field of around 50 tokens around the current time step [35].
An emerging body of research suggests that State Space Models (SSMs) can serve as an alternative to Transformers because they are able to capture dependencies in extremely long sequences, while being more computationally efficient and parallelizable [14]. While still falling into the category of autoregressive sequence models, the underlying linear time-invariant dynamical system of SSMs allows the efficient processing of sequences using parallelizable convolution operators with the Fast Fourier Transform (FFT) [7], with O(L log L) complexity, where L is the length of the sequence. Moreover, retention of past information over long sequences, up to thousands of steps, can be ensured by deriving recurrent update rules by borrowing ideas from online function approximation [3, 12]. SSMs have recently outperformed Transformers on long-range dependency benchmarks by a large margin [37]. Despite their success on long-range classification tasks, SSMs have not yet completely matched Transformers as an off-the-shelf sequence model for general language modeling tasks [10].

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

2 RELATED WORK
Instruction-Tuned Large Language Models Large language models (LLMs) have showcased exceptional generative capabilities in a wide range of natural language processing (NLP) tasks (Brown et al., 2020; Thoppilan et al., 2022; Hoffmann et al., 2022; Chowdhery et al., 2022). By leveraging techniques such as supervised instruction tuning and reinforcement learning from human feedback (RLHF), LLMs exhibit remarkable few- and zero-shot generalization capabili- ties (Ouyang et al., 2022; Wei et al., 2022; Sanh et al., 2022; Chung et al., 2022; Muennighoff et al., 2022; OpenAI, 2023; Anil et al., 2023). Recently, Wang et al. (2022c) highlight the lack of diversity in human-written instructions and demonstrate that machine-generated instructions can be used for instruction tuning. Since then, several instruction-tuned LLMs have been ï¬ne-tuned using various machine-generated instruction datasets (Taori et al., 2023; Chiang et al., 2023; Li et al., 2023b). More surprisingly, Wu et al. (2023b) reveal that instruction-following is not solely a prop- erty of LLMs, as even relatively small language models can follow instructions when ï¬ne-tuned on large-scale instruction datasets.

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

and wording. Furthermore, numerous tasks within CMMLU have answers specific to China, which may not be universally applicable or considered correct in other regions or languages.
We assess GPT4, ChatGPT, and more than 20 advanced open-source multilingual and Chinese LLMs on CMMLU. The results reveal that the majority of these models struggle to achieve an accuracy score of 60%, relative to random accuracy of 25%. Notably, GPT4 achieves an average accuracy of 71%. These findings highlight the considerable room for improvement in LLMs in terms of Chinese knowledge and language understanding.
To gain a deeper understanding of the proficiency of the models in handling Chinese knowledge, we conduct a comprehensive analysis. We first focus on examining model performance across various subjects and find that all models exhibit uneven performance across different subjects, with comparatively higher scores in humanities and social sciences, but lower scores in China-specific and STEM subjects.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

In this work, we are motivated by this essential goal of evaluating explanations (specifically, Chain- of-Thought [7]) rationales) from the perspective of teaching and improving weaker agents in solv- ing reasoning tasks. In order to improve smaller modelsâ reasoning skills, recent works propose knowledge distillation by fine-tuning a smaller model on the reasoning steps generated by a larger model [8, 9, 10]. Yet, an important component of human teaching is understanding when and how the teacher should explain particular things to the student. Current distillation approaches do not evaluate a teacherâs ability to identify when a student lacks understanding, and past work has not explored how to personalize teacher explanations to the studentâs needs. A smaller student model might already be good at answering certain questions but might require the teacherâs intervention for some harder questions. When there are many things to teach the student and teaching is laborious, it is important to choose which problems merit explanation in order to improve teaching efficiency [11]. Moreover, for more effective teaching, it is desirable to have the teacher personalize its explanations to help a particular student, and a teacher that lacks understanding of the studentâs needs (i.e., lacks Theory of Mind) will be unable to do this [3].

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

To tackle these challenges, researchers have pro- posed several interactive visualization tools to help users explore embedding spaces (e.g., Smilkov et al., 2016; Liu et al., 2019). These tools often visu- alize embeddings in a low-dimensional scatter plot where users can browse, filter, and compare embed- ding points. However, for large datasets, it is taxing or even implausible to inspect embedded data point by point to make sense of the global structure of an embedding space. Alternatively, recent research explores using contour plots to summarize embed- dings (Sevastjanova et al., 2022; Robertson et al., 2023). Although contour abstractions enable users to obtain an overview of the embedding space and compare multiple embeddings through superposi- tion, a user study reveals that contour plots restrict usersâ exploration of an embeddingâs local struc- tures, where users would prefer to have more visual context (Robertson et al., 2023). To bridge this crit- ical gap between two visualization approaches and provide users with a holistic view, we design and develop WIZMAP (Fig. 1). Our work makes the following major contributions:

3. Methodology: We introduce a new technique to avoid mode collapse when using rein- forcement learning for automatic prompt generation.
In particular, our experiment to elicit false text from GPT-3-text-davinci-002 demonstrates the value of contextually refining the target behav- ior compared to using a pre-existing classifier. As a control, we consider an attack that targets a classifier trained on the CREAK dataset, which contains factual statements labeled as true and false. This is the type of approach that has been used in prior work such as Perez et al. (2022b). In contrast, by using target model data for the explore and establish steps, we pro- duce the CommonClaim dataset, which labels 20,000 GPT-3-text-davinci-002 generations as true, false, or neither, according to human com- mon knowledge. The âneitherâ label makes the target classifier more robust and harder to hack with statements that are not claims about the world. Meanwhile, common knowledge false- hoods â statements that are obviously false â are an easier target behavior. We show that attacks with the CommonClaim classifier elicited statements about political topics com- monly targeted by misinformation. In contrast, the CREAK classifier appeared to provide a more hackable reward signal because it led to prompts that were neither true nor false.

Recent findings suggest that Transformers and SSMs are complementary models for the purpose of language modeling [28]. In this work, we propose an architecture that integrates a strong local attention-based inductive bias with the long-term context modeling abilities of SSMs into a single layer, that we call Block-State Transformer (BST). Our model is able to process long input sequences, while still incorporating an attention mechanism to predict next tokens. BST is fully parallelizable, scales to much longer sequences, and offers a 10Ã speedup compared to comparable Transformer- based layers.

State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

Multi-Modality Drawing inspiration from the human learning process, artiï¬cial intelligence (AI) researchers are actively exploring the combination of different modalities to train deep learn- ing models. With the success of LLMs, feature alignment among multiple modalities has at- tracted great interest for its applications. There is a line of research works that learns a joint embedding space for multiple modalities (Radford et al., 2021; Baevski et al., 2022; Girdhar et al., 2023). Some researches also attempt to combine the pre-trained vision-only and language-only models, showcasing impressive zero-shot capabilities (Alayrac et al., 2022; Li et al., 2023c; Su et al., 2022). More recently, a number of works explore to enable the multi-modal LLMs to follow the instructions (Zhu et al., 2023; Ye et al., 2023; Li et al., 2023a; Chen et al., 2023; Gong et al., 2023; Dai et al., 2023).

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

Furthermore, through extensive experiments, we find that: (1) most existing models do not benefit from chain-of-thought prompts in CMMLU; (2) few-shot examples help foundation models in the comprehension of tasks and enhance their reasoning abilities but do not help models that have undergone supervised fine-tuning (SFT) or reinforcement learning from human feedback (RLHF); (3) LLMs perform worse on questions with negation words compared to those without negation words, but recently-released models mitigate this disparity either through better pre-training data or fine-tuning; and (4) questions with sub-options (Section 4.2) are difficult for all existing LLMs, with even GPT4 dropping 20% in accuracy over such questions.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

Motivated by the efficiency of human explanations, we consider a student-teacher framework where a teacher model guides the reasoning of a student model, with the goal of improving the studentâs reasoning on current and future data. In order to do so, we explore a Theory of Mind-inspired approach, where the teacher simulates the studentâs behavior by building a mental model of the student. Our overall research question investigates whether the teacherâs intervention (in the form of natural language explanations) can enable the student to make more accurate predictions both on explained as well as unexplained future data. However, communication is expensive, and therefore we assume that a cost is incurred each time the teacher intervenes with (communicates) an explanation to the student for a particular data point. We refer to this as the intervention budget, the percentage of test data points the teacher intervenes on. In order to comprehensively answer our overall research question, we further decompose the teaching problem into the following constituent questions:
1. RQ1. Can a teacher LLM intervene at test time to improve a student LLMâs predictions?
2There have also been strong arguments against the presence of ToM in current LLMs [5, 6]. In this paper, we do not thoroughly test for ToM abilities in LLMs, but instead we focus on measuring teaching performance in terms of a teacherâs positive effect on student performance.

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

Figure 1: Our approach for realistic red-teaming. The red team begins only with a high-level un- derstanding of what failures might look like. The end result is a labeled dataset, a measure for harm- ful outputs, and a generator for prompts that elicit them. Prior works (Section 4) assume that the Ex- plore and Establish steps are already done.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

In every BST layer, an SSM takes the entire sequence as input and maps it into a âcontextâ sequence of the same length. The SSM sublayer takes advantage of FFT-based convolutions. This sequence of context is then divided into blocks of equal size, i.e. window length (W ), and each context block is then fed to a Block Transformer layer, that attends to the subsequences of size W as defined in [21]. The block of input token embeddings are then cross-attended to the corresponding block of context states; see Figure 1. Note that by introducing SSMs as a means of contextualization, we completely remove the need for sequential recurrences and we are able to run our hybrid SSM- Transformer layer fully in parallel. The resulting runtime complexity can be expressed as the sum of O(W 2) + O(L log L), where the first term represents the time complexity of the Transformer sublayer, while the second term represents the time complexity of the SSM sublayer. This is a major improvement over O(LW ) of Block-Recurrent Transformer, so long as hardware to support parallel computation is available. Moreover, due to hardware imposed restrictions, the runtime complexity of the SSM on a full sequence is

# 2 RELATED WORK
Benchmarking plays a crucial role in measuring AI development, particularly in the domain of LLMs. While benchmarks such as GLUE (Wang et al., 2019b) and SuperGLUE (Wang et al., 2019a) have played an important role in tracking progress in natural language understanding (NLU) tasks, they primarily focus on specific language skills. With an increasing move to generative models which are highly adept at generating fluent outputs, the value of these benchmarks has diminished, and new datasets have been proposed to evaluate LLM abilities over more general tasks, such as reading comprehension (Rajpurkar et al., 2018; Kwiatkowski et al., 2019; Li et al., 2022), summarization (Hermann et al., 2015), commonsense reasoning (Clark et al., 2018; Talmor et al., 2019; Sakaguchi et al., 2020), mathematical reasoning (Hendrycks et al., 2021b; Cobbe et al., 2021), and code generation (Chen et al., 2021; Austin et al., 2021).

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

We develop WIZ- MAP with modern web technologies such as WebGL and Web Workers so that any- one can access the tool directly in both their web browsers and computational note- books without a need for dedicated backend servers (§ 4.4).

# 2 Background and Related Work
Researchers can extract a data pointâs embed- dings by collecting its corresponding layer acti- vations in neural networks trained for specific tasks such as classification and generation (Raghu et al., 2019). Additionally, researchers have developed task-agnostic models, such as word2vec (Mikolov et al., 2013), ELMo (Peters et al., 2018), and CLIP (Radford et al., 2021) that generate trans- ferable embeddings directly. These embeddings have been shown to outperform task-specific, state- of-the-art models in downstream tasks (Radford et al., 2021; Dwibedi et al., 2021).

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

# 2 METHODS
We consider a team of humans that has trained and plans to deploy an LM. As is often the case with LMs, it might sometimes output harmful text. If the team knows these issues precisely (e.g. saying specific bad phrases (Zou et al., 2023)) or has a suitable classifier for them (e.g. a pretrained toxicity classifier (Perez et al., 2022b)), then red-teaming is like finding a needle in a haystack. The goal is simply to search the modelâs input space for a small set of prompts that elicit the harmful outputs. However, language models often fail in unforeseen ways, and their harmful behaviors are not always well anticipated or defined in advance. In reality, red-teaming is often more like searching for a vaguely described needle in a haystack full of different needles. Our goal is to red-team the target model in a way that is both realistic, and that focuses on the target modelâs outputs in its intended deployment context (as opposed to some pretrained classifierâs training distribution). We do this in three steps which are illustrated in Figure 2.
Step 1, Explore the range of model behaviors: The objective of this step is to acquire diverse samples from the modelâs outputs, enabling a user to examine the range of behaviors it can produce.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

so long as hardware to support parallel computation is available. Moreover, due to hardware imposed restrictions, the runtime complexity of the SSM on a full sequence is comparable to that of Block Transformer on a block of tokens, which further implies the absence of a speed bottleneck in the BST layer, empirically validated for sequences containing hundreds of thousand of tokens. This is evident by observing that the bottom-most two lines on the left of Figure 4 are almost overlapping.

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

In this section, we provide a comprehensive description of MACAW-LLM. We begin by presenting an outline of the model architecture, followed by a detailed description of each individual module within MACAW-LLM, namely the modality module, alignment module, and cognitive module. Lastly, we provide an in-depth explanation of the training process of MACAW-LLM.

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

# Under review
In order to comprehensively assess the capabilities of LLMs, some benchmarks have incorporated massive multi-task evaluations into their frameworks (Hendrycks et al., 2021a; Liang et al., 2022; Srivastava et al., 2023). An example is MMLU (Hendrycks et al., 2021a), which includes multiple domains and tasks based on real-world exams. It has become very popular for LLM evaluation due to its standardized and simplified format, comprehensive nature, and real-world relevance. However, all aforementioned benchmarks are primarily focused on English.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

5. RQ5. Can misaligned teacher LLMs lower student performance by providing misleading explana- tions to the student?
We answer RQ1 by assuming that the teacher intervenes on random data points in four different settings: using a human or LLM teacher, and, when the teacher is an LLM, using an LLM student that is either weaker or stronger than its teacher (§5.1). Across three different reasoning tasks (StrategyQA, GSM8k, and CommonsenseQA) and two different model families (Flan-T5 and LLaMA), we observe that (1) teacher LLMs can effectively intervene on student reasoning, improving student performance on the end task, and (2) more intervention typically leads to a monotonic increase in student per- formance, though model teachers are not as good as human teachers. Fig. 1 shows the intervention process and the two student prompts (in the right part of Fig. 1) that are used to generate predictions.

# 2.1 Dimensionality Reduction
Embeddings are often high-dimensional, such as 300-dimensions for word2vec, or 768-dimensions for CLIP and BERT Base (Devlin et al., 2018). Therefore, to make these embeddings easier to visu- alize, researchers often apply dimensionality reduc- tion techniques to project them into 2D or 3D space. Some popular dimensionality reduction techniques include UMAP (McInnes et al., 2020), t-SNE (van der Maaten and Hinton, 2008), and PCA (Pear- son, 1901). Each of these techniques has its own strengths and weaknesses in terms of how well it preserves the embeddingsâ global structure, its stochasticity, interpretability, and scalability. De- spite these differences, all dimensionality reduction techniques produce data in the same structure. This
means users can choose any technique and visual- ize the projected embeddings with WIZMAP.

Explore Establish Exploit Cluster & RL Reward Function Subsample samp orn Harmfulness ample |â> â> | classifier J LJ
Figure 2: A step-by-step illustration of our approach. First, we sample from the target model and then subsample to obtain a diverse dataset of outputs. Then we obtain labels for the examples and train a harmfulness classifier on the labels. Finally, we train an adversarial prompt generator to produce diverse prompts that elicit harmful outputs from the target model.
To improve the efficiency with which the user can explore the output domain, we use diversity sampling to better represent the modelâs range of possible behaviors. In light of recent work studying how the internal activations of models may contain information analogous to intentions (Evans et al., 2021), we use the internal activations of the target model to guide diversity subsampling. We sample outputs and embed them using the last token activations in the modelâs last layer, use K-means clustering to partition the embeddings into clusters, and uniformly sample sentences from each cluster to obtain a diverse subsample.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

# 2 Related Work
This work is primarily related to two branches of recent research: (i) combining local attention with recurrent networks in order to extend their capacity to capture long-range dependencies, beyond the length of the attention window size, and (ii) State Space Models (SSMs) which describe sequences via linear dynamical systems whose outputs can be computed in parallel. Block-Recurrent Transformer (BRECT) [21] uses a recurrent memory mechanism to extend the theoretical context length of the Transformer. In the recurrent unit of the BRECT cell, the updates made to the ârecurrent state vectors,â are extracted by employing a cross-attention mechanism over a block/window of input token embeddings. Different from their work, we use linear state space models instead of recurrent cells to maintain context states. We also conduct a more extensive exploration of maintaining and updating context states. Earlier works that augment transformers with a non-differentiable external memory include the Memorizing Transformer [42]. Transformer-XL [8] was an early work that combined recurrent memory with Transformers. Our work can be seen as a continued evolution of those models incorporating state-of-the-art recurrent memory models inspired by SSMs.

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

We present an overview of MACAW-LLM in this section. As shown in Figure 1, there are three major modules in MACAW-LLM as follows:
⢠Modality Module: Existing LLMs primarily focus on processing textual information. To in- corporate additional modalities such as visual and audio data, we integrate extra modality encoders into MACAW-LLM. This enhancement enables our MACAW-LLM to handle multiple modalities effectively.
⢠Alignment Module: Since each modality encoder is trained independently, the learned repre- sentations of different modalities may not be directly compatible. To address this, we propose the alignment module, which uniï¬es the representations from different modalities, enabling effective integration of multi-modal information.
⢠Cognitive Module: LLMs have demonstrated remarkable capability in understanding and fol- lowing human instructions. In MACAW-LLM, we leverage pretrained LLMs as our cognitive module, which forms the foundation of MACAW-LLM. It is worth noting that the cognitive module also serves as the textual modality encoder in our approach.

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

Given that Chinese is the language with the largest number of speakers worldwide, several bench- marks have been proposed for Chinese LLM evaluation. Following in the footsteps of GLUE and SuperGLUE, Xu et al. (2020) introduced CLUE, a benchmark for Chinese NLU that is widely used today. They also recently proposed SuperCLUE (Xu et al., 2023), which specifically focuses on LLMs. Recently, several Chinese benchmarks have emerged that follow the MMLU style, all of which are concurrent work with ours. In detail, Zhang & Li (2023) proposed ACLUE, focusing on ancient Chinese language understanding. Zeng (2023) presented MMCU, which covers four major domains (medicine, law, psychology, and education), with a particular focus on medicine and education. AGIEval (Zhong et al., 2023) provides problems from both Chinese and English standardized exams. C-Eval (Huang et al., 2023) and M3KE (Liu et al., 2023) collect more than 50 tasks from standard exams in China, while C-Eval covers various professions, and M3KE focuses on education examinations.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

RQ2 explores how to intelligently select which data points to explain for the student model, in order to improve teaching efficiency (§5.2). Past work in cognitive science also considers teaching efficiency in young children by deciding what to teach by maximizing the learnerâs expected utility of learning [12]. With a similar motivation, we develop an Intervention Function that is inspired from the principle of a teacher having a Theory of Mind. In particular, the teacher builds a mental model of the studentâs reasoning process, with the goal of intervening only on samples that are most likely to maximize student performance. Our Intervention Function is based on Expected Utility, in which the teacher first estimates the utility of an intervention by simulating the studentâs prediction pre-intervention (without intervention) and post-intervention (with intervention), then constructs a rank ordering of the samples according to this utility (see the middle part of Fig. 1). The teacher builds this mental model in a few-shot manner, only assuming access to the studentâs predictions pre- and post-intervention for a few samples. We demonstrate that our proposed Intervention Function based on Expected Utility (1) outperforms other baseline Intervention Functions, (2) improves student performance when the teacher is not 100% accurate, and (3) enables weaker LLMs to teach stronger ones, unlike with random intervention in RQ1.

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

Researchers have introduced interactive visualiza- tion tools to help users explore embeddings (e.g., Liu et al., 2018; Li et al., 2018; Arendt et al., 2020). For example, Embedding Projector (Smilkov et al., 2016) allows users to zoom, rotate, and pan 2D or 3D projected embeddings to explore and in- spect data point features. Similarly, Deepscat- ter (Schmidt, 2021) and regl-scatterplot (Lekschas, 2023) empowers users to explore billion-scale 2D embeddings in their browsers. Latent Space Cartog- raphy (Liu et al., 2019) helps users find and refine meaningful semantic dimensions within the embed- ding space. In addition, researchers have designed visualizations to aid users in comparing embed- dings, such as embComp (Heimerl et al., 2022) visualizing local and global similarities between two embeddings, Emblaze (Sivaraman et al., 2022) tracing the changes in the position of data points across two embeddings, and Embedding Compara- tor (Boggust et al., 2022) highlighting the neighbor- hoods around points that change the most across embeddings.

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and

Step 2, Establish a way to identify failures: This step involves analyzing the data from the Explore step and developing a measure for harmful outputs. In this step, we use humans (or, for experimental purposes, a classifier to serve as a quantitative proxy for a human) to label examples. We choose a label set so that one of the labels represents undesirable outputs. We then use paraphrasing aug- mentation (Damodaran, 2021) to balance the datasets and train an ensemble of 5 RoBERTa-based text-classifiers from Aghajanyan et al. (2021). Important to this step is human interaction with the modelâs outputs. Instead of using an off-the-shelf classifier, this requires the red team to choose a set of labels to characterize the modelâs behavior in the intended deployment context and develop a way to identify failures. Interacting with the data in this step also allows the red team to refine their understanding of failures. We perform a version of this in Section 3.2, and we overview prior works on the importance of preference-formation for red-teaming in Section 5.

State space models can be considered as linear RNNs [12]. This simplicity facilitates their analysis and even enables analytical derivation of recurrent weights for optimally representing arbitrarily long sequences. The linear property also allows the recurrence to be unrolled and parallelized during training and inference [14]. Our work combines these state-of-the art models, enabling Transformers to leverage theoretically infinite context.

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

Figure 1 provides a visual representation of the MACAW-LLM architecture, while Section 3.2 and Section 3.3 offer detailed explanations of the modality module and alignment module, respec- tively. As the cognitive module of MACAW-LLM, the effectiveness of instruction-tuned LLMs has been demonstrated by several previous works (Ouyang et al., 2022; Wei et al., 2022; OpenAI, 2023; Taori et al., 2023; Chiang et al., 2023; Anil et al., 2023), and we follow their practices in our MACAW- LLM.
3.2 MODALITY MODULE
Existing LLMs are highly powerful but typically limited to processing only textual information. In this section, we describe how we encode information from different modalities.

Preprint (work in progress)
Visual Modality Encoder Radford et al. (2021) propose a novel framework, known as CLIP (Radford et al., 2021), which exploits a signiï¬cantly wider range of supervision by directly learn- ing from unprocessed textual data related to images. In this work, we utilize the capabilities of CLIP-VIT-B/16 for encoding visual information, including images and video frames.

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

Compared to these benchmarks, CMMLU has several distinct features. Firstly, it includes more than 10 subjects that are not typically found in standard exams but are relevant to daily life, such as Chinese food culture, and Chinese driving rules. Secondly, it covers not only China-specific knowledge but also general world knowledge, such as world religion, world history, and global facts. Lastly, we have made our data completely public, enabling the community to evaluate their models freely and conveniently. A detailed comparison between CMMLU and other concurrent benchmarks is provided in Appendix A.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

Next, in RQ3, we explore how the teacher should explain data points to a particular student model, in- cluding how the teacher can personalize explanations for a student model (§5.3). That is, after deciding which data points to intervene on (RQ2), we decide how the teacher should explain those data points. A clear limitation of the teacher just generating explanations as if it is solving the task is that the expla- nations are not at all personalized for the student. Given that good explanations are designed to fill in gaps in student knowledge [2], we believe that equipping the teacher with basic personalization skills will improve its teaching ability. With this motivation, we propose another few-shot mental model for the teacher that encourages it to tailor its explanations to be helpful for the particular student model it is teaching. The teacher builds this model by conditioning on a few demonstrations of âusefulâ human explanations that rectify a studentâs answer, thereby encouraging explanations that are more likely to help the student (see Fig 1 for an example of the teacherâs personalization prompt). We demonstrate this promptâs effectiveness against unpersonalized explanations that are generated by prompting the teacher with random human explanations, showing that LLMs can personalize their explanations.

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

Step 3, Exploit the modelâs weaknesses with adversarial prompts: After obtaining a classifier for harmful model outputs, the final step is to attack the target model. We use reinforcement learning (RL) to train an adversarial prompt generator to produce prompts that trigger undesirable com- pletions from the target model. We use RL attacks for three reasons: 1) they have been used in prior works (Deng et al., 2022; Perez et al., 2022b); 2) they are entirely generalizable because they treat the target model as a black box; and 3) once the prompt generator is trained, new adversarial prompts can be cheaply sampled as many times as desired. We use the trlx library (CarperAI, 2022) to finetune GPT-2-large using Proximal Policy Optimization to produce a distribution of prompts that elicit outputs from the target LM that are classified as harmful. The reward used to train the prompt generator has two terms. The first is from the Establish step classifierâs logit confidence in the completionâs harmfulness. The second, which is novel to this work, is based on the intra-batch cosine distances of the target LMâs embeddings of the generated prompts. We added this because mode collapse by the prompt generator has been a challenge in prior works (Deng et al., 2022; Perez et al., 2022a).

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

Other works have attempted to replace Transformers, and their attention mechanism with SSMs [28, 27, 10, 30], however despite recent progress, the performance achieved by the Transformer architecture remains unparalleled in language. Nevertheless, SSMs are able to capture longer range dependencies than Transformers in both theory and practice, while also being highly parallelizable [7, 11]. We therefore elect to combine the best aspects of SSMs and Transformers into a single model. The idea of communication across blocks, similar to GSS [28], was later implemented by MEGA [27], through an Exponentially Moving Average (EMA) update rule instead of SSMs2. However, both GSS and MEGA use a single-head Gated Attention Unit (GAU) [20]. MEGA further mixes layer inputs, GAU outputs and EMA outputs via two gating mechanisms. Our method uses a simpler architecture to mix signals from local attention and SSM outputs via cross-attention, allowing us to plug any out-of-the-box SSMs or attention layers. Further, we investigate three ways to mix SSM signals with attention as outlined in Section 3.3.

Audio Modality Encoder Radford et al. (2022) introduce a novel multilingual speech recogni- tion model called WHISPER (Radford et al., 2022). This model is trained on a vast audio dataset with weak supervision. In MACAW-LLM, we leverage the power of WHISPER-BASE to encode the audio signals, thereby extracting meaningful representations from the audio data.
Textual Modality Encoder LLMs are commonly pre-trained on the massive text corpora, so instruction-tuned LLMs can naturally process text information. In this work, we consider LLAMA-7B (Touvron et al., 2023) as the foundation of MACAW-LLM.
We acknowledge the existence of numerous publicly available pre-trained models that can serve as modality encoders. However, we leave the investigation of their utility to the future work.
3.3 ALIGNMENT MODULE
Modality encoders are typically trained separately, leading to potential discrepancies in the rep- resentations generated by different encoders. As a result, it becomes crucial to align these inde- pendent representations within a joint space. In this section, we outline the approach we employ to align these representations.

# 3 CMMLU
Task Overview We created an extensive multitask test for Mandarin Chinese, which covers diverse areas of knowledge, including the humanities, social sciences, STEM (science, technology, engi- neering, and mathematics), and other areas that are important in daily life. It includes common test questions in subjects like mathematics, physics, and chemistry with answers that are not language or region specific, but also several tasks that are very region-specific, such as Chinese driving rules, Chinese food culture, and Chinese teacher qualifications. The questions in these tasks involve lots of China-related knowledge and can test a modelâs understanding and adaptability to Chinese. In addition, CMMLU also contains tasks that can only expressed in Chinese, such as ancient Chinese language and Chinese literature. The terms and concepts involved in these tasks heavily rely on Chinese expression and are almost impossible to be obtained from translation. The full list of subjects, the concepts tested in each subject, the number of questions, and the statistics of question and answer lengths are provided in Appendix B.

RQ4 tests whether LLMs can teach student models to generalize to new unexplained examples (§5.4), rather than improve their reasoning at test-time (RQ1-RQ3). In other words, we now explore the ability of LLMs to teach using the teaching components introduced in RQ2 and RQ3 of when and how to explain samples. This leads us to explore a multi-round interactive setting, where each round consists of the teacher selecting a set of best points to explain (according to RQ2) and generating explanations for them (according to RQ3). The student then conditions on these teacher explanations as in-context demonstrations to perform the reasoning task on future unexplained samples. We demonstrate that teacher explanations indeed generalize and improve student performance on unexplained data.
Finally, in RQ5, we investigate the negative implications of teacher explanations on student LLMs (§5.5). Given that LLMs can improve student agents, we also want to test whether they can lower student performance. If a misaligned teacher provides non-factual explanations in scenarios where the

student directly adopts them, does that lead to a drop in student performance? In fact, we show that teacher models can lower student performance to random chance by intervening on data points with the intent of misleading the student. This has potential implications for LLMs giving explanations in a context where other agents adopt them with unwarranted trust in their correctness.

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization

A hallmark property of explainable AI models is the ability to teach other

agents. To address this, we consider a student-teacher framework between two

natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their

first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by

# 3 Multi-scale Embedding Summarization
Researchers have highlighted usersâ desire for embedding visualizations to provide visual con- texts and embedding summaries to facilitate ex- ploration of various regions within the embedding space (Robertson et al., 2023). However, generat- ing embedding summaries is challenging for two reasons. First, efficiently summarizing millions of data points in larger datasets can be a formidable task. Second, selecting the embedding regions to summarize is difficult, as users possess varying in- terests in regions of different sizes and levels of granularity. To tackle this challenge, we propose a novel method to automatically generate multi- resolution embedding summaries at scale.
Multi-resolution Quadtree Aggregation. First, we apply a dimensionality reduction technique such as UMAP to project high-dimensional embedding vectors into 2D points. From these points, we con- struct a quadtree (Finkel and Bentley, 1974), a tree data structure that recursively partitions a 2D space

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

# 3 EXPERIMENTS
We designed two experiments. We set out to 1) study the feasibility of identifying contextual target behaviors, 2) measure the value of our diversity objective for automatic red-teaming, and 3) demon3
# Preprint
strate the value of a contextual classifier compared to a generic classifier. In realistic red-teaming tasks, it is hard to precisely quantify the effectiveness of attacks. Thus, we first investigated points 1 and 2 in a synthetic experiment that uses a toxicity classifier as a quantitative proxy for human judgment. We demonstrate the approachâs feasibility and find that the diversity objective is needed to prevent mode collapse during RL.
Next, to look at a more realistic setting, we investigated all three points in an experiment that red teams GPT-3-text-davinci-002 to produce false text. We perform the Establish step by asking knowl- edge workers to assign common-knowledge labels to generations from GPT-3-text-davinci-002. We use a combination of prompting and filtering to sample statements that make factual claims. How- ever, this still produced many generations that were neither true nor false by common knowledge irrespective of context. As a result, we also used a third category. We asked knowledge workers to label sentences as neither when they were neither clearly true nor false by common knowledge. We call the resulting dataset CommonClaim and used it to train a classifier used in the Exploit Step.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

# 3 Method
We consider the problem of next token prediction via a decoder-only language model. This seemingly simple pretext task has led to spectacular progress in language understanding [9, 2, 29]. During training, the decoder takes in a sequence of length L of tokens embeddings and is tasked to generate the next token at every step in the sequence.
We start by a brief review of SSMs that are essential for understanding the Block-State Transformer layer (3.1). Our full Block-State Transformer architecture is outlined in Section 3.2. Section 3.3 describes three approaches for integrating SSM states into the attention mechanism. Important implementation details are described in Section 3.4.
# 3.1 State Space Preliminaries
State space models can be divided into two categories:
State Spaces: Structured Kernels S4 [14], S5 [34], S4D [15], DSS [16], follow a structured initialization of the convolutional kernel by unrolling a linear time-invariant (LTI) dynamical system of the following form:
xk = Axkâ1 + Buk , yk = Cxk + Duk . (1)
2The authors in [27] show a mathematical form of EMA that has a state transition and also derive a convolution kernel to efficiently compute EMA similarly to S4.

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

Multi-Head Self-Attention (MHSA) Scaled dot-product attention is a fundamental component of the Transformer model (vaswani et al} PO17)- It operates on three inputs: the query vector Qe R4*4k the key vector K ⬠Râ«*â«, and the value vector V ⬠Râ«*4 This attention mecha- nism calculates attention weights by comparing the queries Q with the keys K. It then uses these weights to update the query representations through a weighted sum of the values V and can be described as follows:
QK' Attn(Q,K, V) = softmax(ââ)V, (1) Va
where dk is the dimensionality of the key and query vectors, and nq and nk are the number of queries and keys, respectively.
Modality Alignment The alignment strategy is designed to efficiently connect multi-modal fea- tures with textual features, facilitating quicker adaptation. In this work, we refer to the image and video features obtained from our visual modality encoder (i.e. CLIP) as x; ⬠REixdi and a, ⬠RL»*4v, respectively. Additionally, we denote the audio features from the audio modality encoder (i.e. WHISPER) as &q ⬠R'«*â<, The process of modality alignment is outlined as follows:

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

Data collection We hired four annotators with undergraduate or higher education levels to manually collect the questions and answers from freely available resources, at a rate of 50 CNY per hour. To prevent our questions from appearing in the training set of LLMs, we invested specific effort in identifying non-publicly available materials, mock exam questions, and questions from quiz shows. More than 80% of our data was crawled from PDFs (after OCR), which further reduces the possibility of it occurring in LLM training data. The entire collection process took around 250 hours.
Format Each question in the dataset is a multiple-choice question with 4 choices, only one of which is correct; see Figure 2 for an example. The questions are expressed as fillâinâthe-blank (by choosing the correct option), or direct-answer questions. For chemical formulae and mathematical expressions, we use a 50:50 mixture of LATEX and plain text, where plain text was only allowed if an expression is commonly used and not prone to ambiguity (as judged by the annotators). For instance, the chemical expression for water can be written in plain text as H2O, or in LATEX format as $H {2}O$.
Quality Check To further check data quality, we randomly sampled 5% questions with answers for each subject, and conduct detailed verification through online resources. We estimate that there is

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

In summary, our comprehensive studies highlight the ability of LLMs to teach and improve weaker LLMs, demonstrated via improvements on explained test examples as well as future unexplained data. Broadly, equipping LLMs with an ability to effectively and efficiently teach, opens the door to (1) using LLMs as personalized tutors for humans (where efficiency is critical), (2) distilling knowledge into weaker or more compute-efficient student models, and (3) improving human decision making via AI recommendations and explanations.

into four equally-sized squares, each represented as a node. Each data point exists in a unique leaf node. To summarize embeddings across different levels of granularity, we traverse the tree bottom up. In each iteration, we first extract summaries of embeddings in each leaf node, and then merge the leaf nodes at the lowest level with their parent node. This process continues recursively, with larger and larger leaf nodes being formed until the entire tree is merged into a single node at the root. Finally, we map pre-computed embedding summaries to a suitable granularity level and dynamically show them as users zoom in or out in WIZMAP (§ 4.1).

To demonstrate the value of contextually defining the target behavior, we compare with a control condition where the classifier is trained on the CREAK dataset of true and false statements. We found that red-teaming with this classifier was unsuccessful. The prompt-generator in the Exploit step learned to generate toxic and nonsensical text that was nonetheless reliably classified as false by the CREAK classifier. On the other hand, using the CommonClaim classifier led the red LM to generate prompts related to U.S. politics (with frequent mentions of âDemocratsâ, âRepublicansâ, âObamaâ and âRussiaâ). It elicited responses that appear to include topics associated with mis- or disinformation.

Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or

adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

The system is parameterized by a state matrix A â RN ÃN , vectors B â RN Ã1, C â R1ÃN , and D â R1Ã1, the SSM maps a 1-D input signal uk, to a 1-D output signal yk. Internally, the SSM projects the input signal to an N -D representation state xk, before mapping it down to a scalar using the C matrix. The term Duk can be thought of as a skip connection and will be omitted for the remainder of the discussion for convenience. The output of the above recurrent equation, yk, can be computed as a discrete convolution, by realizing that the recurrence can be explicitly unrolled:

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

1. Encoding: We ï¬rstly leverage the pre-trained models ,CLIP and WHISPER, to encode multi- modal features:
hj =CLIP(x;), hy =CLIP(axy)), ha = WHISPER(Zaq), (2) where h; ⬠R!i*4, hy ⬠Rââ*4 and hg ⬠R'«*@" are image, video, and audio features, respec- tively, and dp is the dimension of modality-specific features.
2. Transformation: To reduce computational costs and minimize the number of tokens in the preï¬x, we employ a 1-D convolutional layer to compress the length of the multi-modal fea- tures to a smaller and ï¬xed value. Subsequently, a linear layer is employed to adjust the hidden size of the features, aligning it with the size of the LLMs embeddings as follows:

=Linear(Conv1D(h;)), h',
=Linear(Conv1D(h,)), hi,

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

Evaluating Explanations in Teacher-Student Games. Several past works evaluate explanations in the context of a student-teacher communication game [13, 14, 15, 16, 17]. The teacher communicates explanations to the student with one of two objectives: (1) evaluating whether explanations help students to simulate the teacher better, or (2) whether explanations can directly teach students to better perform a task. Simulatability, or the studentâs ability to simulate the teacherâs own answer, is seen as a measure of the explanationâs faithfulness, rather than a direct measure of whether explanations help students learn the task itself [18, 19]. Our work is focused on the second research goal of evaluating explanations from the perspective of teaching weaker agents. Prior work has shown that human explanations can teach LLMs [7, 20] and LLMs can also teach themselves from their own explanations or feedback [21, 22]. But it remains to be shown whether LLMs can also teach weaker agents. A few recent works also share a similar goal as ours and they distill knowledge [23] directly into the student model by finetuning it on the explanations from the teacher model [8, 9,

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

Scalable Leaf-level Summarization. When per- forming quadtree aggregation, researchers have the flexibility to choose any suitable method for summarizing embedding from leaf nodes. For text embeddings, we propose t-TF-IDF (tile-based TF- IDF) that adapts TF-IDF (term frequency-inverse document frequency) to extract keywords from leaf nodes (Sparck Jones, 1972). Our approach is simi- lar to c-TF-IDF (classed-based TF-IDF) that com- bines documents in a cluster into a meta-document before computing TF-IDF scores (Grootendorst, 2022). Here, we merge all documents in each leaf node (i.e., a tile in the quadtree partition) as a meta- document and compute TF-IDF scores across all leaf nodes. Finally, we extract keywords with the highest t-TF-IDF scores to summarize embeddings in a leaf node. This approach is scalable and com- plementary to quadtree aggregation. Because our document merging is hierarchical, we only con- struct the n-gram count matrix once and update it in each aggregation iteration with just one matrix multiplication.

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

3.1 ELICITING TOXIC TEXT FROM GPT-2-XL
In this experiment, we red team the 1.5B parameter GPT-2-xl. First, we sample a total of 80,000 sentences from the target LM. To avoid biasing samples toward sentences that begin pieces of text, we sample paragraphs at a time without prompting and parse them into individual sentences. We use a pre-trained RoBERTa-based toxicity classifier (Liu et al., 2019; Adams et al., 2017)) as a quantitative proxy for a human and label examples from the Explore step. We classified inputs with a toxicity probability of ⥠0.1 from the classifier as toxic. The base rate of toxic text was <1%, but we used paraphrasing augmentation based on Parrot (Damodaran, 2021) to balance the dataset. The ensemble of classifiers achieved average accuracies of > 99% on nontoxic sentences and 76% on toxic sentences from the validation set. We used the reinforcement learning method described in Section 2 to train a model to generate prompts that elicit toxic text from GPT-2-xl.

K = (CB,CAB,...,CAâ~'B), x (3) "YR = SO Kj un; y = Keu. j=0
Given an input sequence u â RL, it is possible to compute the output y â RL sequentially through the recurrence in Equation (1). While this property is useful for autoregressive decoding, sequential computation is prohibitively slow to train with long inputs and, instead, the convolution from the Equation (3) can be used to compute all elements of y in parallel. This is done via Fast Fourier Transform (FFT) [7], provided we have already computed K.
Additional inductive biases have been imposed on SSMs by analytically deriving closed-form expressions for the matrices A and B using the HiPPO framework [12]. In this framework, the state xt represents the coefficients of polynomials that approximate the sequence ut.

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

3. Alignment: Each modality encoder is trained separately, resulting in distinct representations for different modalities. To establish a common representation space, it becomes necessary to align these representations across modalities. In this work, we consider the transformed visual and audio modality representations obtained in Equation 3 as the soft tokens of LLM, the cognitive model, so we propose to align the visual and audio representations with the textual embedding space using the attention mechanism in Equation 1 as follows:

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

share a similar goal as ours and they distill knowledge [23] directly into the student model by finetuning it on the explanations from the teacher model [8, 9, 10, 24]. However, these distillation methods do not consider the important aspects of communication cost between two agents, its trade-off with student performance, and how the teacher may build mental models of the student to decide when and how to communicate explanations to the student. Recent studies have also evaluated explanations in the context of human-AI collaboration, for their plausibility [25, 26], usefulness to human learning [27, 28], and for improving human-AI team performance [29, 30]. Different from these, we analyze model-model interactions, with the goal of understanding how effectively LLMs can teach weaker systems to solve a task.

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

3.1.1 RESULTS
Toxicity increased by over 30x: We independently ran the Exploit step twice to obtain two ad- versarial prompt generators. We used the toxicity classifier as a proxy for a human to compare the toxicity of the target model unprompted versus with prompts from the generators. The human-proxy classifier classified the data from the Explore step as toxic <1% of the time. In contrast, the outputs under adversarial prompts were classified as toxic an average of 31% of the time. This demon- strates successful prompt-generation attacks and transfer from the Establish step classifier to the human-proxy classifier.
The prompt generators learned to discuss sensitive topics: We randomly sampled five comple- tions from each of our prompt generators that were classified as toxic and display them alongside their prompts in Table 1 (content warning). The generators learned to discuss topics including men, women, homosexuality, and police officers. We observe that the prompts themselves are relatively benign compared to the completions, which are both more offensive and more diverse in topic. We also observe some disfluencies in the form of repeated words or phrases in the prompts, which may be either adversarial motifs or artifacts of the prompt generator.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

Explicitly Parameterized Filters In contrast to structured kernels, one can parameterize the convolution kernel, as trainable weights and optimize them, ¯K â RL. However, this would result in poor performance unless certain types of regularization are applied to the kernel. [11] simply makes use of squashing the kernel weights, and subsequently applying a smoothing technique. Trainable kernels are also used in attention-free alternative models to Transformers, such as Hyena [30], which involves exponentially decaying the weights along the kernel:
K, = e %- (FFNo PositionalEncoding) (t) , (4) where K, is an entry in the filter at location t, and FFN is a feed-forward network used for decoupling the parameter count from the seuqnece length.

h® = Attn(hâ,E,E), is the modality representation obtained in (.e. hi,
,EEE ,EEE ), (4)
where hâ is the modality representation obtained in (.e. hi, hi, and hi) and h* is the corresponding aligned representation, specifically, hy, hf, and hf. After such an alignment operation facilitated by the attention mechanism, the LLM (cognitive module) can seamlessly process the representations from various modalities.
4. Integration: The integration of aligned modality representations into the instruction can be achieved effortlessly through the concatenation operation. Given the aligned modality repre- sentations, the integration can be deï¬ned as follows:
x = [ha i : ha v : ha a : Embed(xt)], (5)
where [:] represents the concatenation operation, x represents the multi-modal instruction, xt represents the sequence of tokens in the textual instruction, and Embed(xt) represents the sequence of embeddings of xt.

Theory of Mind in AI. A body of work demonstrates that humans regularly infer and make decisions based on the mental states of other agents, also known as Theory of Mind (ToM) [31, 3, 2, 32]. This has motivated works on computational language acquisition using ToM [33, 34, 35]. There have been recent works arguing both for and against the presence of Theory of Mind in Large Language Models [36, 4, 6, 37]. Theory of Mind has been successfully applied to improve human-AI collaboration in robotics [38, 39, 11]. In this work, we design prompts that are motivated by a teacher having a Theory of Mind to efficiently intervene and improve a studentâs reasoning capabilities.

# 4 User Interface
Leveraging pre-computed multi-resolution embed- ding summarization (§ 3), WIZMAP tightly inte- grates three interface components (Fig. 1AâC).
4.1 Map View The Map View (Fig. 1A) is the primary view of WIZMAP. It provides a familiar map-like interface that allows users to pan and zoom to explore differ- ent embedding regions with varying sizes. To help users easily investigate both the global structure and local neighborhoods of their embeddings, the Map View integrates three layers of visualization.
Distribution Contour. To provide users with a quick overview of the global structure of their embeddings, we use Kernel Density Estimation (KDE) (Rosenblatt, 1956) to estimate the distri- bution of 2D embedding points. We use a stan- dard multivariate Gaussian kernel with a Silverman bandwidth for the KDE model (Silverman, 2018). Next, we compute the distribution likelihoods over a 200Ã200 2D grid whose size is determined by the range of all embedding points. Finally, we vi- sualize the likelihoods over the grid as a contour plot (Fig. 4), highlighting the high-level density distribution of usersâ embeddings. Researchers can adjust the grid density, and we tune it by balancing the computation time and the contour resolution.

Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

Producing diverse adversarial prompts was needed to avoid mode collapse: To test the impor- tance of diversity, we ran the Exploit step without the diversity term in the reward function. In this case, we observed mode collapse where the model learned to output repetitive prompts that almost entirely consisted of the words âwouldâ and âyouâ and had a 0% toxic completion rate. We show examples in Appendix B.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

# 3.2 Block-State Transformer (BST) Layer
We now introduce the Block-State Transformer layer, which combines SSMs with Block Transformers. At each training iteration, a sequence of L tokens, is sampled from a longer document. The tokens are then embedded and fed to the model. Our model consists of a stack of Block-State Transformer layers. Each BST layer optionally includes an SSM sublayer that is responsible for providing long-range context to the Block Transformer layer, which operate similarly to a Block-Recurrent Transformer (BRECT) cell. The SSM sublayer takes the sequence of token embeddings from the previous layer as input, and produces a sequence of the same length L as the output.
The output of the SSM is contextually encoded, meaning that entries at every time-step, potentially include information about all the time steps preceding elements in the sequence. We collect a number of âcontext states,â S, from the context sequence, and we set S ⪠L. In order to prevent the model from accessing future information, we only allow the model to access context states that precede the current token. Various ways to gather context states from the context sequence are discussed in section 3.3 in detail.

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

In this section, we describe how we align the multi-modality representation into a shared repre- sentation space using the attention mechanism. It is important to note that our model, MACAW- LLM, has the capability to process multiple modalities concurrently, while the textual instruction xt is always necessary as part of the instruction x. We intend to investigate the direct utilization of visual or audio instructions in our future work.
3.4 ONE-STEP INSTRUCTION FINE-TUNING
The common multi-modal practice in previous works involves two-step training (Li et al., 2023c; Liu et al., 2023; Dai et al., 2023). The ï¬rst step focuses on training the projection layer to align multi-modal features with textual features, while the second step involves ï¬ne-tuning the gen- eral instruction for LLMs. In contrast, our approach, MACAW-LLM, simpliï¬es the adaptation process by employing a one-step instruction ï¬ne-tuning approach. This approach ensures co- herent alignment across the modalities and eliminates the potential risk of error propagation that can occur in multi-step ï¬ne-tuning procedures.

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

# 3 Problem Setup
Student and Teacher. We assume a two-agent communication game between a student S and a teacher T , where the goal is to teach the student to solve a particular task interactively. Here, we use an LLM as the student. To explore a range of student and teacher capabilities, we consider both human and model teachers, while typically using a student model that is measurably weaker than its teacher. Following past work, an LLM with more parameters is considered a stronger model due to its better performance across a range of tasks (including the ones we consider in our studies). In the scope of our study, when the teacher is not a human, both S and T are LLMs, prompted with a set of demonstrations of the task D (typically, 4-8 examples). Each demonstration d(i) â D is a triple (x(i), y(i), e(i) H that answers the question of why the data point has the output it has [1]. In our tasks, the explanation may include background knowledge or intermediate reasoning steps that are helpful for obtaining the answer. By organizing D into Chain-of-Thought prompts, both S and T are equipped with the ability to generate explanations and predict labels for new samples.
Single-Round Intervention. The first problem setup we consider involves the teacher deciding whether or not to intervene for a single test problem. In this setting, the studentâs goal is to answer

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

Multi-resolution Labels. The Map View helps users interpret embeddings across various lev- els of granularity by dynamically providing pre- computed contextual labels. It overlays summaries generated via quadtree aggregation (§ 3) onto the distribution contour and scatter plot. Users can hover over to see the summary from a quadtree tile closest to the cursor. Our tool adjusts the labelâs tile size based on the userâs current zoom level. For ex- ample, when a user zooms into a small region, the Map View shows summaries computed at a lower level in the quadtree. In addition to on-demand em- bedding summaries, this view also automatically labels high-density regions (Fig. 4) by showing summaries from quadtree tiles near the geometric centers of high-probability contour polygons.

In this work, we ï¬ne-tune all the parameters θ in MACAW-LLM, and the objective is to minimize the negative log-likelihood over the response y with respect to θ as follows:
N L(y;0) =-Â¥ log P(y;|x;9), () i
where N denotes the number of tokens in y and y j is the j -th token in y. By employing such a one-step ï¬ne-tuning strategy, MACAW-LLM can effectively harmonize the different modules.

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

Single-Round Intervention. The first problem setup we consider involves the teacher deciding whether or not to intervene for a single test problem. In this setting, the studentâs goal is to answer
4
the problem correctly, and the teacher can choose to intervene for individual problems to assist the student. Thus, given a test data point t(i), we have the following two scenarios:
⢠No Intervention: When the teacher chooses not to intervene, the student generates both the S , by conditioning on the D task demonstrations and the test explanation e(i) input t(i). This is done using Chain-of-Thought prompting [7]. S and the prediction Ëy(i)
⢠Intervention: When the teacher does choose to intervene, it communicates its generated explana- tion to the student. Here the student only generates a prediction Ëy(i) S by conditioning on the D task demonstrations, the test input t(i), and the corresponding teacher explanation e(i) T . For the tasks and datasets we consider, explanations provide helpful background information or reasoning steps but do not directly reveal the test label, so it never directly gives away the answer.

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

Because only a small fraction of all types of sentences are statements of a potential fact, we used a combination of prompting and filtering to obtain a more relevant dataset. First, we prompted the model to ask it for interesting facts.1 Second, we filtered generations with a classifier that was trained to distinguish between sentences from the target model and between factual claims from the CREAK dataset (Onoe et al., 2021). We used this classifier to filter the 15% of generations that least resembled factual claims. Finally, we filtered text based on other simple heuristics.2. Finally, internal activations of the target model were not available via API, so we instead used embeddings from GPT-3-text-ada-002, a dedicated text encoder.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

In addition to the ability of SSMs to retain information over longer time horizons compared to Transformers and RNNs, using the SSM to maintain context states as a replacement for recurrent cells makes for a more computationally efficient layer. Removing recurrence by integrating SSMs into Transformer layers, allows the Block-State Transformer layer to be fully parallelizable, whereas the Block-Recurrent architecture processes blocks of tokens sequentially using a for loop.
# 3.3 Context States
Although the latest SSM output technically contains information about the entire sequence, retrieving individual tokens from only the final state may not be feasible. To compensate, we concatenate a sequence of states, corresponding to the latest block of tokens. This is also analogous to the approach taken by BRECT. This representation ensures retrievability and ease of access, through redundancy. It is redundant because adjacent states are highly correlated, however this also makes it possible to easily recover the current block of tokens, if necessary.

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

4 MACAW-LLM INSTRUCTION DATASET
Current multi-modal datasets, such as visual question answering (Antol et al., 2015; Goyal et al., 2017), summarization (Li et al., 2017; Jangra et al., 2023), and dialogue (Shuster et al., 2021; Sun et al., 2022), predominantly emphasize speciï¬c task types, resulting in a limited diversity of tasks. Additionally, the target text in these datasets often lacks proper alignment with the style of human-written text, making it difï¬cult for models ï¬ne-tuned on such data to effectively follow human instructions. To address these limitations, we utilize the remarkable generative capability of current LLMs (i.e. GPT-3.5-TURBO) to curate our MACAW-LLM instruction dataset.
To generate the dataset, we utilize the power of GPT-3.5-TURBO. We provide it with a prompt in the form of an image or video caption (see Figure 3). To optimize the generation process and improve efï¬ciency, we generate 10 instruction-response pairs within a single query. For image

Fig. 1 shows the âNo Interventionâ and âWith Interventionâ student prompts and the overall interven- tion process. Note that in terms of the prompts used for both these scenarios, the only difference is in the source of explanation (student vs teacher) for the test point. When the teacher is a human, intervention happens with a human-written explanation (crowdsourced in the datasets we rely on).

A hallmark property of explainable AI models is the ability to teach other

communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should

that teacher LLMs can indeed intervene on student reasoning to improve their

that misaligned teachers can lower student performance to random chance by

# 4.2 Control Panel
The Map View shows all three visualization layers by default, and users can customize them to fit their needs by clicking buttons in the Control Panel (Fig. 1C). In addition, WIZMAP allows users to compare multiple embedding groups in the same embedding space by superimposing them in the Map View (Gleicher, 2018). In the case of em- beddings that include times, users can use a slider (shown on the right) in the Control Panel to observe changes in the embeddings over time (Fig. 5).

# 4.3 Search Panel
Searching and filtering can help users discover interesting embedding patterns and test their hy- pothesis regarding the embedding structure (Carter et al., 2019). In WIZMAP, users can use the Search Panel (Fig. 1B) to search text embeddings includ- ing specified words in the original data. The panel shows a list of search results, and the Map View highlights their corresponding embedding points.

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

Establishing a classifier using the CommonClaim dataset: One challenge with developing honest AI systems is what standard to hold the model to. For example, should reasonable-sounding false statements be judged differently than blatant falsehoods? This distinction may be of significance for both interpreting and correcting these failures (Evans et al., 2021). Thus, we focused on the simpler problem of eliciting obviously false statements. We asked contractors to label generations as true by common knowledge and false by common knowledge. As a result of the explore step, we also iden- tified the need for an additional category of neither true nor false to account for statements that were opinions, vague, obscure, uncommon knowledge, or otherwise hard to categorize as true or false by common knowledge. This choice to add a âneitherâ label offers an example of how interaction with Explore-step data can cause a red team to modify their understanding of failures in order to tailor red-teaming to the model. We instructed contractors to label each example based on how likely they think a typical person would know something to be reasonably true or false. All details involving contractor selection and instructions are in Appendix C. We are making these 20,000 statements from the Explore step, each with two independently-collected human labels available. In total, 60%

toward securing models, these approaches rely on a pre-existing way to

Exploiting the model's flaws using this measure to develop diverse adversarial

that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

In our approach, the context states are constructed from the output of the SSM and fed to the attention heads of the Transformer. These context states can be constructed in various ways. To guide these design decisions we consider each of the below proposed schemes as introducing retrievability at the cost of redundancy. The shape of the output of a single SSM layer is (B à L à D), where B is the batch size, L is the number of the tokens processed, and D is the embedding dimension. When doing cross-attention in the Transformer cell with H different heads, this tensor needs to be transformed into a context tensor of shape (B à S à D à H), where S is the number of context states; we usually set S ⪠L and S = W similar to Block-Recurrent Transformers (BRECT).
We now discuss the three different approaches that we evaluate to generate a context tensor for each block sequence:

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

around 2% of noise in the data, in terms of the correct answer not being present or being incorrectly labeled. Based on the results in Section 4 that most models struggle to achieve an average accuracy of 60%, we believe such an error rate does not compromise the overall results.
Statistics CMMLU contains 11,528 questions across 67 subjects. Each subject has at least 105 questions, which we split into a few-shot development set with 5 questions, and a test set with more than 100 questions. In terms of task types, CMMLU comprises 17 STEM tasks, 13 humanities tasks, 22 social science tasks, and 15 other tasks. Among these, 16 tasks are China-specific, which means they either do not exist in other countries or regions, or their answers may be different in other places. We provide an example for each subject type in Appendix C.
# 4 EXPERIMENTS
To provide an overview of existing LLMs on language understanding within the context of Chinese, we evaluate two commercial LLMs and more than 20 open-source LLMs in different sizes, language orients, and stages (i.e. either foundation model or SFT/RLHF model). We analyse their performance and investigate several factors that could affect the performance of LLMs.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

Communication Cost. In Single-Round Intervention, the teacher could maximize student perfor- mance by simply always intervening on the studentâs reasoning. We bring in a natural constraint from Rational Speech Acts theory, i.e., communication is costly and should only be undertaken if it furthers a communicative goal [40]. Hence, we assume that a communication cost is incurred each time the teacher intervenes with an explanation to the student. We also note that this cost is only with respect to an agentâs communication (and assume that the teacher can always generate explanations for itself). Unless otherwise stated, communication happens one-way from the teacher to the student in the form of explanations. We set a limit to the number of points that the teacher can intervene on, referred to as the intervention budget, and we assume the cost to be uniform for all data points. Across all our experiments, we vary the intervention budget between {0%, 20%, 40%, 60%, 80%, 100%}. A budget of 0% means the student generates its own explanation as it predicts each data point, while a budget of 100% means the student leverages the teacherâs explanation for every data point. Later, in Sec. 5.2, we introduce the teacher Intervention Function, which the teacher uses to decide which points to intervene on given its fixed intervention budget.

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

We now discuss the three different approaches that we evaluate to generate a context tensor for each block sequence:
SH: Single-Head The first approach constructs the context tensor by sequentially concatenating the S states from the SSM with a single filter (each of size D). Note that because the SSM captures information from preceding blocks, the context state also captures information about blocks that preceded the current block. The resulting context vector is highly retrievable and redundant, as defined above. As in typical Transformers, fully connected layers are used to project each context vector to H different heads of size D. Note that in the cross-attention operation, context states that correspond to future tokens from the current block need to be causally masked out. In this case we set S = W , and we pick the window of SSM outputs that correspond to the current block, and a
5
triangular mask is used to implement causal masking of context states. This approach is shown in Figure 1.

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

Your focus should be on describing, explaining, or analyzing various aspects of the image/video, as well as providing some QA pairs. The purpose of this exercise is to ï¬ne-tune a language model so that it can generate accurate and relevant responses.
In each pair, the ï¬rst line should start with "Q:" and contain an instruction related to the im- age/video, while the second line should start with "A:" and provide a response to the instruction.
Please ensure that your instructions are diverse and of high quality, accurately reï¬ecting the content of the image and providing useful information to the language model:
# Output:
Q: Can you describe the color of the river in the image? A: The river in the image appears to be a tranquil shade of blue.
Q: What type of boat is the man in the image paddling? A: The man in the image is paddling a kayak.
Q: How do you think the man in the image is feeling while paddling down the river? A: Judging by the peaceful surroundings and the calm pace of the paddling, itâs likely that the man in the image is feeling relaxed and at ease. ......

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.

Setup Our goal is to assess the LLMs performance on CMMLU, which contains multiple-choice questions with one correct answer for each question. There have been several strategies to perform multiple-choice question-answering task. In this paper, for commercial models which we cannot get the weights (i.e., GPT4 and ChatGPT), we input the question with all candidate choices, allowing the model to generate the output, and use a series of regular expressions (regex) to match the modelâs prediction. We call this free generation strategy. For open-source models, we follow Hendrycks et al. (2021a) to input the question and choices, and prompt the model by asking the answer key. Then we obtain the logits of the next predicted token, and compare the probability among the 4 tokens: âAâ, âBâ, âCâ, and âDâ and select the token with the highest probability as the modelâs choice. We named this as next token prediction strategy. Besides these two strategies, there is another way which is to select the answer with the lowest perplexity when concatenated with the question.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

Multi-round Intervention. Here, the goal of the teacher is to provide explanations to the student that help it generalize across samples, rather than leading the student to the correct answer only for the explained data points. Thus, we allow the teacher to explain data points that are then added to the student modelâs prompt, but we forbid the teacher from intervening on future test points. If the teacher can improve the quality of the student modelâs prompt, student performance on the test data should improve. In our experiments, this process occurs in a few steps: (1) the teacher picks points to explain, (2) the teacher explains those points, (3) the points are added to the student prompt with the teacherâs explanations, and then (4) the student predicts labels for the remaining test data. Further implementation details are given in Sec. 5.4.

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

For example, when exploring 63k ACL in the Control Panel animates the visualizations to show embeddings of paper abstracts, clicking the play button papers published in each year in purple and the distribution of all papers in blue. This animation highlights changes in ACL research topics over time, such as the decline in popularity of grammar and the rise of question-answering.

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

of statements were labeled common knowledge-true (T/T or T/N), 22% common knowledge-false, (F/F or F/N), and 18% neither (N/N or T/F). Table 2 shows examples of each type.3 Both annota- tors agreed on 60.5% of examples. 27.7% of the time, one marked an answer common knowledge true/false while the other marked neither. 11.7% of the time, the two were in direct disagreement. We name this the CommonClaim dataset. We trained an ensemble of 5 classifiers as done before with data augmentation but on three labels instead of two.4
Training a control classifier using the CREAK dataset: we use the CREAK (Onoe et al., 2021) dataset, which contains a total of 5779 and 5768 claims labeled as true and false. The 5 classifiers trained on the CREAK data achieved average accuracies of 78% on true sentences and 75% on false sentences from the validation set. Because the CREAK classifier was trained with pre-existing data, it parallels how red-teaming has been approached in prior works without using data from the target model or a custom label set.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

triangular mask is used to implement causal masking of context states. This approach is shown in Figure 1.
MH: Multi-Head This approach differs from Single-Head (SH) in that here the SSM is tasked to generate a separate output for different heads. We use separate [C1, C2, ..., CH ] matrices, to produce context states that are fed to the attention heads. This enables the SSM to extract comple- mentary features from the summarized history. The conceptual difference is that the C matrix, from Equation (1), has direct access to the full memory state of the SSM (xk), that in theory could be thought of as a compact representation of the history, before it gets mapped down to a scalar. The Multi-Head (MH) approach is illustrated on the left side of Figure 2. Because the H different C matrices may extract complementary information, the context vector constructed by this method is theoretically less redundant compared to the single-head method described above.

We compared different strategies in Appendix G, and found that next token prediction is the most efficient way. Therefore, for the majority of the remaining paper, we report the results of the next token prediction. However, for some analysis in Section 4.2, we use the free generation strategy. The regex is designed based on the observation of ChatGPT and ChatGLM responses. The detail of regex and matching algorithm is provided in Appendix H.

CMMLU: Measuring massive multitask language understanding in Chinese
|
As the capabilities of large language models (LLMs) continue to advance,
evaluating their performance becomes increasingly crucial and challenging. This
paper aims to bridge this gap by introducing CMMLU, a comprehensive Chinese
benchmark that covers various subjects, including natural science, social
sciences, engineering, and humanities. We conduct a thorough evaluation of 18
advanced multilingual- and Chinese-oriented LLMs, assessing their performance
across different subjects and settings. The results reveal that most existing
LLMs struggle to achieve an average accuracy of 50%, even when provided with
in-context examples and chain-of-thought prompts, whereas the random baseline
stands at 25%. This highlights significant room for improvement in LLMs.
Additionally, we conduct extensive experiments to identify factors impacting
the models' performance and propose directions for enhancing LLMs. CMMLU fills
the gap in evaluating the knowledge and reasoning capabilities of large
language models within the Chinese context.

We consider complex natural language reasoning tasks, motivated by two specific needs. First, the task should be hard enough for current LLMs that explanations can provide useful knowledge to the models. Second, it allows us to study free-text rationales, which are more flexible than input attribution methods [41, 42, 43] and benefit many reasoning tasks [7, 44]. We experiment with three reasoning tasks: (1) StrategyQA [45], (2) GSM8k [46], and (3) CommonsenseQA [47] (details in Appendix B). Both StrategyQA and CommonsenseQA contain explanations in the form of relevant facts, thus requiring the student to reason over them to produce an answer. We also manually verify (up to 100 samples) that the explanations do not explicitly leak the answer. For GSM8k, since the reasoning steps explicitly derive the answer, providing the entire explanation during intervention will lead to answer leakage [17]. Hence, the teacher communicates a partial explanation (specifically, only the first step of the rationale), allowing the student to leverage it as a hint to derive the final answer. We experiment with two state-of-the-art open-source

Can Language Models Teach Weaker Agents? Teacher Explanations Improve Students via Personalization
|
A hallmark property of explainable AI models is the ability to teach other
agents, communicating knowledge of how to perform a task. While Large Language
Models perform complex reasoning by generating explanations for their
predictions, it is unclear whether they also make good teachers for weaker
agents. To address this, we consider a student-teacher framework between two
LLM agents and study if, when, and how the teacher should intervene with
natural language explanations to improve the student's performance. Since
communication is expensive, we define a budget such that the teacher only
communicates explanations for a fraction of the data, after which the student
should perform well on its own. We decompose the teaching problem along four
axes: (1) if teacher's test time intervention improve student predictions, (2)
when it is worth explaining a data point, (3) how the teacher should
personalize explanations to better teach the student, and (4) if teacher
explanations also improve students on future unexplained data. We first show
that teacher LLMs can indeed intervene on student reasoning to improve their
performance. Next, inspired by the Theory of Mind abilities of effective
teachers, we propose building two few-shot mental models of the student. The
first model defines an Intervention Function that simulates the utility of an
intervention, allowing the teacher to intervene when this utility is the
highest and improving student performance at lower budgets. The second model
enables the teacher to personalize explanations for a particular student and
outperform unpersonalized teachers. We also demonstrate that in multi-turn
interactions, teacher explanations generalize and learning from explained data
improves student performance on future unexplained data. Finally, we verify
that misaligned teachers can lower student performance to random chance by
intentionally misleading them.

bedding files in parallel with rendering. To enable fast full-time search, we apply a contextual index scoring algorithm with FlexSearch (Wilkerling, 2019). We use D3 (Bostock et al., 2011) for other visualizations and scikit-learn (Pedregosa et al., 2011) for KDE. To ensure that our tool can be easily incorporated into usersâ current workflows (Wang et al., 2023), we apply NOVA (Wang et al., 2022b) to make WIZMAP available within computational notebooks. Users can also share their embedding maps with collaborators through unique URLs. We provide detailed tutorials to help users use our tool with their embeddings. We have open-sourced our implementation to support future research and de- velopment of embedding exploration tools.
# 5 Usage Scenarios
We present two hypothetical scenarios, each with real embedding data, to demonstrate how WIZMAP can help ML researchers and domain experts easily explore embeddings and gain a better understand- ing of ML model behaviors and dataset patterns.

WizMap: Scalable Interactive Visualization for Exploring Large Machine Learning Embeddings
|
Machine learning models often learn latent embedding representations that
capture the domain semantics of their training data. These embedding
representations are valuable for interpreting trained models, building new
models, and analyzing new datasets. However, interpreting and using embeddings
can be challenging due to their opaqueness, high dimensionality, and the large
size of modern datasets. To tackle these challenges, we present WizMap, an
interactive visualization tool to help researchers and practitioners easily
explore large embeddings. With a novel multi-resolution embedding summarization
method and a familiar map-like interaction design, WizMap enables users to
navigate and interpret embedding spaces with ease. Leveraging modern web
technologies such as WebGL and Web Workers, WizMap scales to millions of
embedding points directly in users' web browsers and computational notebooks
without the need for dedicated backend servers. WizMap is open-source and
available at the following public demo link: https://poloclub.github.io/wizmap.

# 3.2.1 RESULTS
The prompt-generators trained on the CommonClaim classifiers learned to discuss Republi- cans, Democrats, Obama, and Russia: The classifiers from the Establish step classified an average of 30% of the Explore phase data as common knowledge-false. However, the same classifiers clas- sified an average of 74% of the completions from the adversarial prompts as common knowledge- false. Table 4 shows examples from these two runs. As before, the prompts contain some disflu- encies which may or may not be adversarial. The adversarial prompt generators learned to output prompts primarily about Republicans, Democrats, Russia, and Barack Obama which elicited com- pletions related to political misinformation. We checked the dataset and labels that the truthfulness classifier was trained on. It contained few political statements. For example, among the sentences with âcommon knowledge-falseâ labels, none mentioned Republicans, one mentioned Democrats,5 and one mentioned Barack Obama.6, and one about Russia and politics7. This lack of training data about politics suggests that the classifiers from the Establish step generalized to learn that these political completions from the target LM were frequently false.

Explore, Establish, Exploit: Red Teaming Language Models from Scratch
|
Deploying large language models (LMs) can pose hazards from harmful outputs
such as toxic or false text. Prior work has introduced automated tools that
elicit harmful outputs to identify these risks. While this is a valuable step
toward securing models, these approaches rely on a pre-existing way to
efficiently classify undesirable outputs. Using a pre-existing classifier does
not allow for red-teaming to be tailored to the target model. Furthermore, when
failures can be easily classified in advance, red-teaming has limited marginal
value because problems can be avoided by simply filtering training data and/or
model outputs. Here, we consider red-teaming "from scratch," in which the
adversary does not begin with a way to classify failures. Our framework
consists of three steps: 1) Exploring the model's range of behaviors in the
desired context; 2) Establishing a definition and measurement for undesired
behavior (e.g., a classifier trained to reflect human evaluations); and 3)
Exploiting the model's flaws using this measure to develop diverse adversarial
prompts. We use this approach to red-team GPT-3 to discover classes of inputs
that elicit false statements. In doing so, we construct the CommonClaim dataset
of 20,000 statements labeled by humans as common-knowledge-true, common
knowledge-false, or neither. We are making code and data available.

In this approach the SSM sublayer produces S context states, which we set to MF: Multi-Filter be independent from W . This is done by convolving the sequence of embeddings with S different kernels/filters. The output of each convolution operation, corresponding to a specific filter, is a tensor of shape (B Ã L Ã D). After convolving the input with all the filters, the context states of size D that correspond to the last token from the previous window are stacked together to make a (B Ã S Ã D) tensor. Feed forward networks are then used to lift this tensor to different heads, (B Ã S Ã D Ã H). Different from the previous two approaches, the context is formed by taking only the last S context states, from the previous window, outputted by the S SSMs. The context is less redundant because it no longer consists of adjacent SSM states. Since the context is taken from the entries of the previous window, cross-attention masking is no longer required, as shown on the right of Figure 2.

Block-State Transformers
|
State space models (SSMs) have shown impressive results on tasks that require
modeling long-range dependencies and efficiently scale to long sequences owing
to their subquadratic runtime complexity. Originally designed for continuous
signals, SSMs have shown superior performance on a plethora of tasks, in vision
and audio; however, SSMs still lag Transformer performance in Language Modeling
tasks. In this work, we propose a hybrid layer named Block-State Transformer
(BST), that internally combines an SSM sublayer for long-range
contextualization, and a Block Transformer sublayer for short-term
representation of sequences. We study three different, and completely
parallelizable, variants that integrate SSMs and block-wise attention. We show
that our model outperforms similar Transformer-based architectures on language
modeling perplexity and generalizes to longer sequences. In addition, the
Block-State Transformer demonstrates more than tenfold increase in speed at the
layer level compared to the Block-Recurrent Transformer when model
parallelization is employed.

caption data from two datasets: Charades (Sigurdsson et al., 2016) and AVSD (AlAmri et al., 2019). These datasets collectively contain 9,848 videos with captions, which we utilize to create our own dataset.
We repeat this process and obtain approximately 69K examples based on COCO image captions and about 50K examples based on Charades and AVSD video captions. The dataset creation pro- cess is illustrated in Figure 2. Table 1 provides statistics about the dataset, including the number of items, the word count of instructions and responses, and examples of each type.
Our current dataset is focused on single-turn dialogues, but we acknowledge the signiï¬cance of including multi-turn dialogues and expanding the dataset to encompass a wider range of multi- modal content. To address this, we are actively engaged in the process of incorporating multi- turn dialogues and diversifying the dataset to enhance its richness. These additions will greatly contribute to enriching the dataset and will be beneï¬cial for the ï¬ne-tuning process of language learning models (LLMs).

Macaw-LLM: Multi-Modal Language Modeling with Image, Audio, Video, and Text Integration
|
Although instruction-tuned large language models (LLMs) have exhibited
remarkable capabilities across various NLP tasks, their effectiveness on other
data modalities beyond text has not been fully studied. In this work, we
propose Macaw-LLM, a novel multi-modal LLM that seamlessly integrates visual,
audio, and textual information. Macaw-LLM consists of three main components: a
modality module for encoding multi-modal data, a cognitive module for
harnessing pretrained LLMs, and an alignment module for harmonizing diverse
representations. Our novel alignment module seamlessly bridges multi-modal
features to textual features, simplifying the adaptation process from the
modality modules to the cognitive module. In addition, we construct a
large-scale multi-modal instruction dataset in terms of multi-turn dialogue,
including 69K image instances and 50K video instances. We have made our data,
code and model publicly available, which we hope can pave the way for future
research in multi-modal LLMs and expand the capabilities of LLMs to handle
diverse data modalities and address complex real-world scenarios.
