³ç´¢èµæç»ã | 2307.04964#91 | Secrets of RLHF in Large Language Models Part I: PPO | Large language models (LLMs) have formulated a blueprint for the advancement
of artificial general intelligence. Its primary objective is to function as a
human-centric (helpful, honest, and harmless) assistant. Alignment with humans
assumes paramount significance, and reinforcement learning with human feedback
(RLHF) emerges as the pivotal technological paradigm underpinning this pursuit.
Current technical routes usually include \textbf{reward models} to measure
human preferences, \textbf{Proximal Policy Optimization} (PPO) to optimize
policy model outputs, and \textbf{process supervision} to improve step-by-step
reasoning capabilities. However, due to the challenges of reward design,
environment interaction, and agent training, coupled with huge trial and error
cost of large language models, there is a significant barrier for AI
researchers to motivate the development of technical alignment and safe landing
of LLMs. The stable training of RLHF has still been a puzzle. In the first
report, we dissect the framework of RLHF, re-evaluate the inner workings of
PPO, and explore how the parts comprising PPO algorithms impact policy agent
training. We identify policy constraints being the key factor for the effective
implementation of the PPO algorithm. Therefore, we explore the PPO-max, an
advanced version of PPO algorithm, to efficiently improve the training
stability of the policy model. Based on our main results, we perform a
comprehensive analysis of RLHF abilities compared with SFT models and ChatGPT.
The absence of open-source implementations has posed significant challenges to
the investigation of LLMs alignment. Therefore, we are eager to release
technical reports, reward models and PPO codes, aiming to make modest
contributions to the advancement of LLMs. | http://arxiv.org/pdf/2307.04964 | Rui Zheng, Shihan Dou, Songyang Gao, Yuan Hua, Wei Shen, Binghai Wang, Yan Liu, Senjie Jin, Qin Liu, Yuhao Zhou, Limao Xiong, Lu Chen, Zhiheng Xi, Nuo Xu, Wenbin Lai, Minghao Zhu, Cheng Chang, Zhangyue Yin, Rongxiang Weng, Wensen Cheng, Haoran Huang, Tianxiang Sun, Hang Yan, Tao Gui, Qi Zhang, Xipeng Qiu, Xuanjing Huang | cs.CL, cs.AI, cs.LG | null | null | cs.CL | 20230711 | 20230718 | [

# A Reward Distribution under PPO Training

Figure 13: We show the distribution of reward model scores over a randomly selected sub-validation set, whose data share the same format and source as the training data. The reward model exhibits identical reward distribution over the stable training period and subsequently exhibits long-tail characteristics after pattern collapse. We argue that different data have different upper bounds on rewards in PPO training, so the best results should appear earlier than the stage at which the collapse occurs.

# B Supplementary Experiments on Hyperparameter Tuning
Here we show supplementary experiments on the parameter sensitivity of the important trick in Sec.5.3, and we ï¬nd a rich correlation between the choice of hyperparameters and training results. Some methods require extensive experimentation and precise control to achieve stable optimization results (e.g., clipping range on entropy bonus). We provide these comparisons to validate the reasonableness of the ï¬nal implementation we adopted in PPO-max. We welcome any additional comments and discussions that may help to further improve PPO training.

Reward scaling with value clip, or normalize and clip for only the reward and advantage are two conï¬gurations that can converge. We, therefore, recommend not mixing the modiï¬cations in the score reparameterization method for PPO training.

different minds yield superior outcomes compared to isolated individuals. In
this work, we propose Solo Performance Prompting (SPP), which transforms a
single LLM into a cognitive synergist by engaging in multi-turn
self-collaboration with multiple personas. A cognitive synergist is an
intelligent agent that collaboratively combines multiple minds' strengths and
knowledge to enhance problem-solving in complex tasks. By dynamically
identifying and simulating different personas based on task inputs, SPP
unleashes the potential of cognitive synergy in LLMs. Our in-depth analysis
shows that assigning multiple fine-grained personas in LLMs improves
problem-solving abilities compared to using a single or fixed number of
personas. We evaluate SPP on three challenging tasks: Trivia Creative Writing,
Codenames Collaborative, and Logic Grid Puzzle, encompassing both
knowledge-intensive and reasoning-intensive types. Unlike previous works, such
as Chain-of-Thought, that solely enhance the reasoning abilities in LLMs,
experimental results demonstrate that SPP effectively reduces factual
hallucination, and maintains strong reasoning capabilities. Additionally,
comparative experiments show that cognitive synergy only emerges in GPT-4 and
does not appear in less capable models, such as GPT-3.5-turbo and
Llama2-13b-chat, which draws an interesting analogy to human development. Code,

Figure 15: The optimization results produce a clear hierarchy when gradually scaling up the weight values of KL-penalty. A looser constraint not only induces higher reward responses but also results in a more pronounced deviation from the original policy distribution. It is worth noting that all settings have some ï¬uctuation problems at the beginning. Such ï¬uctuations disappear only when we use importance sampling to align the responses with the current policy distribution as shown in Figure 7. We hope to ï¬nd a setup to obtain this stability in the training without affecting the optimization results in the future.

Figure 16: We mention the stabilizing effect of the entropy bonus term and its sensitivity in Sec 7. We show the training process with and without clipping it when combining it on a PPO conï¬guration that would converge normally. The learning rate of this loss term is set to 0.01 in all experiments. In code implementation, the entropy bonus is equivalent to a negative term on the loss function, so the model tends to optimize it to as large a value as possible. Delta is a hyperparameter that must be carefully tuned to prevent training collapse (our experiments fail with only a 10% change at this threshold). We, therefore, do not recommend such tricks to RLHF.

Here we present some implementation adjustments to the PPO that are also widely discussed but are judged to be of minor importance to us. The settings of comparison experiments are consistent with those in sec 5.3. We ï¬rst discuss an alternative to the PPO, called the clipped surrogate objective, followed by the impact global gradient clipping. Finally, we discuss the parameter tuning in the Generalized Advantage Estimation (GAE) function, which degrades to the traditional TD error (when λ = 0) or Monte Carlo estimation (when λ = 1), see Sec 3 for more relevant theoretical information about GAE.

# Self-Refine Prompts | 2307.05300#96 | Unleashing the Emergent Cognitive Synergy in Large Language Models: A Task-Solving Agent through Multi-Persona Self-Collaboration | Human intelligence thrives on cognitive synergy, where collaboration among
different minds yield superior outcomes compared to isolated individuals. In
this work, we propose Solo Performance Prompting (SPP), which transforms a
single LLM into a cognitive synergist by engaging in multi-turn
self-collaboration with multiple personas. A cognitive synergist is an
intelligent agent that collaboratively combines multiple minds' strengths and
knowledge to enhance problem-solving in complex tasks. By dynamically
identifying and simulating different personas based on task inputs, SPP
unleashes the potential of cognitive synergy in LLMs. Our in-depth analysis
shows that assigning multiple fine-grained personas in LLMs improves
problem-solving abilities compared to using a single or fixed number of
personas. We evaluate SPP on three challenging tasks: Trivia Creative Writing,
Codenames Collaborative, and Logic Grid Puzzle, encompassing both
knowledge-intensive and reasoning-intensive types. Unlike previous works, such
as Chain-of-Thought, that solely enhance the reasoning abilities in LLMs,
experimental results demonstrate that SPP effectively reduces factual
hallucination, and maintains strong reasoning capabilities. Additionally,
comparative experiments show that cognitive synergy only emerges in GPT-4 and
does not appear in less capable models, such as GPT-3.5-turbo and
Llama2-13b-chat, which draws an interesting analogy to human development. Code,
data, and prompts can be found at:

2307.04964 | 97 | Figure 17: The clipped surrogate objective aims to reduce the complexity increase and estimation error caused by computing the KL divergence. The PPO algorithm with this strategy becomes similar to the TRPO [33] and is generally referred to as PPO2. Some studies argue that this approach can provide approximate results to vanilla PPO [29], but we ï¬nd different clipping value has little effect on the results and does not provide stable optimization as KL constraint.

Figure 18: The global gradient clip is a common strategy to reduce the impact of data noise on the model training, and this setting is usually integrated into the PPO algorithm implementation and automatically enabled. We are concerned about the impact of this setting on policy optimization. Experiments show that itâs difï¬cult to distinguish the difference between different constraints PPO training. This strategy is also enabled by default in our PPO-max implementation.

Figure 19: GAE is an application of reward shaping to estimate a more instructive value function. In general, researchers will concern with the precision and variance of the value estimation. A small λ will reduce the variance of sequence estimation but result in a larger error on the long- range dependence. This ï¬gure shows the results of the estimation of values and corresponding advantages. TD estimation (with λ = 0) provides smaller variance but is numerically more unstable in training, while Monte Carlo estimation exhibits larger variance. Following the implementation of most previous PPO strategy, we set λ = 0.9 in all our other experiments

2307.04964 | 108 | Human Prompt â What does this line mean: Time is just a second hand of love, so tell me why am I in such a rush? (Helpful) SFT Response â This line is expressing the idea that time is merely a measure of our lives and should not be viewed as something to rush through. It suggests that time should be appreciated for its own sake and not just seen as a means to an end. The phrase "second hand of love" implies that love is what truly matters in life, and that time should be spent on loving others and experiencing the things that bring us joy rather than constantly striving towards some future goal or destination. Overall, the line encourages people to slow down and live in the present moment, appreciating the small moments and experiences that make up our lives. RLHF Response â This line suggests that time is not just a measurement of the passing seconds and minutes; rather, it is a symbol or representation of something deeper. In this case, time is equated with "love" - suggesting that the speaker sees time as a force that binds us together and connects us to one another. The idea is that if time is a measure of love, then perhaps we should be more mindful of its importance and not rush | 2307.04964#108 | Secrets of RLHF in Large Language Models Part I: PPO | Large language models (LLMs) have formulated a blueprint for the advancement

advanced version of PPO algorithm, to efficiently improve the training

The idea is that if time is a measure of love, then perhaps we should be more mindful of its importance and not rush through our lives without appreciating the moments that matter most. Here are some possible interpretations of this line: 1. Appreciate the present moment: The message here may be to slow down and appreciate the present moment. Instead of rushing through life, take the time to savor the small things and appreciate the people around you. 2. Love is ï¬eeting: Another interpretation could be that time is ï¬eeting and precious. When seen as a second hand of love, every moment counts, and we should make the most of them by being fully present and engaged in our relationships and experiences. 3. Life is short: This line could also be seen as a reminder that life is short, and we shouldnât waste time on things that donât matter. We should focus on what truly matters to us and prioritize our time accordingly. 4. Overall, this line encourages us to appreciate the beauty of life and the power of love, and to live in the moment instead of always rushing forward towards an unknown future.

â15,000 years ago, a fractured thigh bone was often fatal. However, a human femur that recovered from a fracture marks the dawn of human civilization. It meant that after the injury, someone took care of the wound, someone provided water and food, someone protected this person from the predators. This kind of support and solidarity is how we survived till this day and made our civilization last.â

Abstract: We propose a novel approach to multi-robot collaboration that har- nesses the power of pre-trained large language models (LLMs) for both high-level communication and low-level path planning. Robots are equipped with LLMs to discuss and collectively reason task strategies. They then generate sub-task plans and task space waypoint paths, which are used by a multi-arm motion planner to accelerate trajectory planning. We also provide feedback from the environment, such as collision checking, and prompt the LLM agents to improve their plan and waypoints in-context. For evaluation, we introduce RoCoBench, a 6-task bench- mark covering a wide range of multi-robot collaboration scenarios, accompanied by a text-only dataset for agent representation and reasoning. We experimentally demonstrate the effectiveness of our approach â it achieves high success rates across all tasks in RoCoBench and adapts to variations in task semantics. Our di- alog setup offers high interpretability and ï¬exibility â in real world experiments, we show RoCo easily incorporates human-in-the-loop, where a user can commu- nicate and collaborate with a robot agent to complete tasks together.

2307.04657 | 2 | # Introduction
The recent advent of large language models (LLMs) [1, 2, 3, 4, 5] promises vast transformative potential across multiple sectors, from healthcare [6, 7, 8] and education [9, 10, 11] to robotics [12, 13, 14] and commerce [15]. However, as these models grow in complexity and influence, ensuring their alignment with human values and safety becomes increasingly critical. If left unchecked, LLMs can amplify misinformation, enable harmful content, or yield unintended responses that can cause significant negative societal impact [16, 17, 18, 19]. Recent papers have highlighted significant safety risks associated with the deployment of LLMs in real-world applications, prompting public concern [20, 21, 22].
The urgent need for safety alignment in LLMs has garnered substantial attention from both academia and industry. This surge of interest has led to noteworthy contributions aimed at making LLMs safer. Among these are innovative alignment techniques, namely âred-teamingâ, extensively employed by research groups at Anthropic and DeepMind [23, 18]. Red-teaming involves a rigorous adversarial process that intentionally seeks to expose the potential for harmful outputs from LLMs, which are then refined to decrease the likelihood of such harmful occurrences. Anthropic has gone a step further by

# Introduction
Multi-robot systems are intriguing for their promise of enhancing task productivity, but are faced with various challenges. For robots to effectively split and allocate the work, it requires high-level understanding of a task, and consideration of each robotâs capabilities such as reach range or pay- load. Another challenge lies in low-level motion planning: as the conï¬guration space grows with the number of robots, ï¬nding collision-free motion plans becomes exponentially difï¬cult. Finally, traditional multi-robot systems typically require task-speciï¬c engineering, hence compromise gen- eralization: with much of the task structures pre-deï¬ned, these systems are incapable of adapting to new scenarios or variations in a task. | 2307.04738#2 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the
power of pre-trained large language models (LLMs) for both high-level
communication and low-level path planning. Robots are equipped with LLMs to
discuss and collectively reason task strategies. They then generate sub-task
plans and task space waypoint paths, which are used by a multi-arm motion
planner to accelerate trajectory planning. We also provide feedback from the
environment, such as collision checking, and prompt the LLM agents to improve
their plan and waypoints in-context. For evaluation, we introduce RoCoBench, a
6-task benchmark covering a wide range of multi-robot collaboration scenarios,
accompanied by a text-only dataset for agent representation and reasoning. We
experimentally demonstrate the effectiveness of our approach -- it achieves
high success rates across all tasks in RoCoBench and adapts to variations in
task semantics. Our dialog setup offers high interpretability and flexibility
-- in real world experiments, we show RoCo easily incorporates

sharing their red-team dataset publicly, which contains human-written prompts and human-preference data [18]. Another alignment technique, known as Reinforcement Learning from Human Feedback (RLHF), has also demonstrated promising results [24, 25, 11]. In fact, OpenAIâs GPT-4 technical report disclosed their use of safety-relevant RLHF training prompts and rule-based reward models (RBRMs) [11] to empower safety alignment. While these alignment techniques can be applied in parallel, their effectiveness hinges on the availability of comprehensive human feedback, which necessitates costly large-scale data labeling operations. | 2307.04657#3 | BeaverTails: Towards Improved Safety Alignment of LLM via a Human-Preference Dataset | In this paper, we introduce the BeaverTails dataset, aimed at fostering

2307.04738 | 3 | We propose RoCo, a zero-shot multi-robot collaboration method to address the above challenges. Our approach includes three key components: ⢠Dialogue-style task-coordination: To facilitate information exchange and task reasoning, we let robots âtalkâ among themselves by delegating each robot to an LLM agent in a dialog, which allows robots to discuss the task in natural language, with high interpretability for supervision. ⢠Feedback-improved Sub-task Plan Generated by LLMs: The multi-agent dialog ends with a sub-task plan for each agent (e.g. pick up object). We provide a set of environment validations and feedback (e.g. IK failures or collision) to the LLM agents until a valid plan is proposed.
⢠LLM-informed Motion-Planning in Joint Space: From the validated sub-task plan, we extract goal conï¬gurations in the robotsâ joint space, and use a centralized RRT-sampler to plan motion trajectories. We explore a less-studied capability of LLM: 3D spatial reasoning. Given the start, goal, and obstacle locations in task space, we show LLMs can generate waypoint paths that in- corporate high-level task semantics and environmental constraints, and signiï¬cantly reduce the motion plannerâs sample complexity. | 2307.04738#3 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

2307.04657 | 4 | In light of advancing efforts for the safety alignment of LLMs, we are pleased to open-source our Question-Answering (QA) dataset, BEAVERTAILS. Inspired by our sibling project, PKU-BEAVER, focused on Safe RLHF [26], the BEAVERTAILS dataset aims to facilitate the alignment of AI assistants towards both helpfulness and harmlessness. Our dataset brings forward two types of annotations: (1) Annotated safety meta-labels for over 330,000 QA pairs, derived from more than 16,000 unique red-teaming related prompts. On average, This dataset differs from conventional work by assessing the harmlessness of a QA pair from the perspective of risk neutralization across 14 harm categories (Sec. 3.3). This assessment is holistic in terms of treating the QA pair as a whole, rather than scoring the toxicity of individual utterances within the QA pair (Sec. 4.1). (2) A collection of two distinct sets of human-preference data, each containing over 360,000 pairs of expert comparisons. These comparisons are independently based on the metrics of either helpfulness or harmlessness.

We experimen- tally demonstrate the effectiveness of RoCo on the benchmark tasks: by leveraging the common- sense knowledge captured by large language models (LLMs), RoCo is ï¬exible in handling a variety of collaboration scenarios without any task-speciï¬c training.
In summary, we propose a novel approach to multi-robot collaboration, supported by two technical contributions: 1) An LLM-based multi-robot framework (RoCo) that is ï¬exible in handling a large variety of tasks with improved task-level coordination and action-level motion planning; 2) A new benchmark (RoCoBench) for multi-robot manipulation to systematically evaluate these capabilities. It includes a suite of tasks that are designed to examine the ï¬exibility and generality of the algorithm in handling different task semantics (e.g., sequential or concurrent), different levels of workspace overlaps, and varying agent capabilities (e.g., reach range and end-effector types) and embodiments (e.g., 6DoF UR5, 7DoF Franka, 20DoF Humanoid). | 2307.04738#4 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

2307.04738 | 6 | Multi-arm Path Planning. Given a sub-task, we use centralized motion planning that ï¬nds trajec- tories for all robots to reach their goal conï¬gurations. Let X â Rd denote the joint conï¬guration space of all N robot arms and Xob be the obstacle region in the conï¬guration space, then collision- free space Xf ree = X \Xob. Given an initial condition xinit â Xf ree, a goal region Xgoal â Xf ree, the motion planner ï¬nds an optimal Ïâ : [0, 1] â X that satisï¬es: Ïâ(0) = xinit, Ïâ(1) â xgoal. This resulting Ïâ is used by the robotsâ arm joint controllers to execute in open-loop.
3 Multi-Robot Collaboration with LLMs We present RoCo, a novel method for multi-robot collaboration that leverages LLMs for robot com- munication and motion planning. The three key components in our method are demonstrated in Fig. 2 and described below: | 2307.04738#6 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

discuss and collectively reason task strategies. They then generate sub-task
plans and task space waypoint paths, which are used by a multi-arm motion
planner to accelerate trajectory planning. We also provide feedback from the

their plan and waypoints in-context. For evaluation, we introduce RoCoBench, a

high success rates across all tasks in RoCoBench and adapts to variations in

2307.04738 | 7 | 3.1 Multi-Agent Dialog via LLMs We assume multi-agent task environments with asymmetric observation space and skill capabilities, which means agents canât coordinate meaningfully without ï¬rst communicating with each other. We leverage pre-trained LLMs to facilitate this communication. Speciï¬cally, before each environment interaction, we set up one round of dialog where each robot is delegated an LLM-generated agent, which receives information that is unique to this robot and must respond strictly according to its role (e.g. âI am Alice, I can reach ...â).
For each agentâs LLM prompt, we use a shared overall structure but with agent-speciï¬c content, var- ied with each robotâs individual status. The prompt is composed of the following key components:

Currently, there are multiple datasets that provide QA pairs with human-preference data. BAD [29] by MetaAI is a dialogue dataset in which annotators attempt to elicit unsafe behaviors from the chat-bot using unsafe utterances, and all utterances are annotated as offensive or safe. REALTOXICITYPROMPTS [16] consists of 100k sentences annotated with toxicity scores from PERSPECTIVE API [30, 31]. The SHP [32] dataset consists of 385k collective human preferences regarding the helpfulness of responses to questions and instructions across 18 different subject areas.

This sub-task plan is ï¬rst passed through a set of validations before going into execution. If any of the checks fail, the feedback is appended to each agentâs prompt and another round of dialog begins. The validations are conducted in the following order, and each one assumes the previous check has passed (e.g. a plan must be parsed before checking for task and agent constraints): 1. Text Parsing ensures the plan follows desired format and contains all required keywords 2. Task Constraints checks whether each action complies with the task and agent constraints 3. IK checks whether each robot armâs target pose is feasible via inverse kinematics 4. Collision Checking checks if the IK-solved arm join conï¬gurations cause collision 5.

From a high-level perspective, the process involves retrofitting a generation quality ranking model using human feedback to derive a reward function, which is utilized to assign a holistic score to evaluate the quality of a generated output. Subsequently, the LMs undergo further training through RL methods such as Proximal Policy Optimization (PPO) [48, 49].

# BEAVERTAILS-30k
⢠Annotated 30,207 QA-pairs across 14 potential harm categories, which correspond to 7,774 unique prompts. Of these prompts, 75.3% received three unique responses, 20.7% received six unique responses, and the remaining 4.1% received over six unique responses.
⢠Within the total set of 30,207 QA pairs, 42.68% were assigned the safe meta-label, while the remaining 57.32% were categorized under the unsafe meta-label.
⢠From the total pool of 30,207 QA pairs, we acquired 30,144 pairs of human-preference annotations separately for the helpfulness and harmlessness metrics of the responses.

Toy Example: 3D Spatial Reasoning Capability in LLMs. As a motivating example, we ask an LLM (GPT-4) to plan multi-agent paths in a 3D grid. We randomly sample 3 agentsâ (start, goal) coordinates and a set of obstacles, and prompt GPT-4 to plan collision-free paths. Given feedback on failed plans, allowing up to 5 attempts, GPT-4 obtains 86.7% success rate over 30 runs, using on average 2.73 attempts. See Fig. 3 for an example output. See Appendix 13 for further details and results. While this capability is encouraging, we found it to also be limited as the grid size and number of obstacles increase.

The tasks involve common-sense objects that are semantically easy to understand for LLMs, and span a repertoire of collaboration scenarios that require different robot communication and coordination behaviors. See Appendix 10 for detailed documentation on the benchmark.

2307.04738 | 14 | 1. Task decomposition: whether a task can be decomposed into sub-parts that can be completed in parallel or in certain order. Three tasks in RoCoBench have a sequential nature (e.g. Make Sandwich task requires food items to be stacked in correct order), while the other three tasks can be executed in parallel (e.g. objects in Pack Grocery task can be put into bin in any order).
2. Observation space: how much of the task and environment information each robot agent receives. Three tasks provide shared observation of the task workspace, while the other three have a more asymmetric setup and robots must inquire each other to exchange knowledge.
3. Workspace overlap: proximity between operating robots; we rank each task from low, medium or high, where higher overlap calls for more careful low-level coordination (e.g. Move Rope task requires manipulating the same object together).

2307.04738 | 15 | Overview. We design a series of experiments using RoCoBench to validate our approach. In Section 5.1, we evaluate the task performance of RoCo compared to an oracle LLM-planner that does not use dialog, and ablate on different components of the dialog prompting in RoCo. Section 5.2 shows empirically the beneï¬ts of LLM-proposed 3D waypoints in multi-arm mo- tion planning. Section 5.3 contains qualita- tive results that demonstrate the ï¬exibility and adaptability of RoCo. Additional experiment results, such as failure analysis, are provided in Appendix 12.
Table 1: Overview of the key properties designed in RoCoBench tasks. Task Decomposition (1st row): whether sub-tasks can be completed in parallel or sequentially; Observation space (2nd row): whether all agents receive the same information of task sta- tus; Workspace Overlap (3rd row): proximity between robots during execution. | 2307.04738#15 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

⢠We acquired 361,903 pairs of human-preference annotations separately for the helpfulness and harmlessness metrics of the responses. The inter-crowdworker agreement rate: safety meta-label = 81.68%, helpfulness preference = 62.39% and harmlessness = 60.91%.
Additionally, we solicited crowdworkers to assign confidence scores to their annotations, applicable to both the classification and response-ranking tasks. The confidence spectrum extended from âvery uncertainâ and âuncertainâ to âcertainâ and âvery certainâ, corresponding to a scale of 0 to 3.

2307.04738 | 16 | 5.1 Main Results on RoCoBench Experiment Setup. We use GPT-4 [1] for all our main results. In addition to our method âDialogâ, we set up an oracle LLM-planner âCentral Planâ, which is given full environment observation, infor- mation on all robotsâ capabilities and the same plan feedback, and prompts an LLM to plan actions for all robots at once. We also evaluate two ablations on the prompt components of RoCo: ï¬rst removes dialog and action history from past rounds, i.e. âDialog w/o Historyâ. Second removes en- vironment feedback, i.e. âDialog w/o Feedbackâ, where a failed action plan is discarded and agents are prompted to continue discussion without detailed failure reasons. To offset the lack of re-plan rounds, each episode is given twice the budget of episode length. | 2307.04738#16 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

2307.04657 | 17 | # 3.2 Data Collection and Annotation Process
Generating QA pairs Our study involves a collection of over 28k red-team prompts derived from the HH RED-TEAM dataset [18] and [56]. Given the dialogical nature of these datasets, we specifically selected the first question that initiated the interaction between the human and the AI assistant. These questions were meticulously crafted by Ganguli et al. to be both provocative and intentionally deceptive, serving as a rigorous test for a language modelâs ability to handle harmful prompts designed to elicit unsafe responses. For questions perceived as overly terse or incomplete, we incorporated additional contextual information during pre-processing. The average word count (using the regex /\w+/) for each prompt is 13.61. | 2307.04657#17 | BeaverTails: Towards Improved Safety Alignment of LLM via a Human-Preference Dataset | In this paper, we introduce the BeaverTails dataset, aimed at fostering

2307.04738 | 17 | Evaluation Metric. Provided with a ï¬nite number of rounds per episode and a maximum number of re-plan attempts per round, we evaluate the task performance on three metrics: 1) task success rate within the ï¬nite rounds; 2) number of environment steps the agents took to succeed an episode, which measures the efï¬ciency of the robotsâ strategy; 3) average number of re-plan attempts at each round before an environment action is executed â this reï¬ects the agentsâ ability to understand and use environment feedback to improve their plans. Overall, a method is considered better if the task success rate is higher, it takes fewer environment steps, and requires fewer number of re-plans.
Results. The evaluation results are reported in Table 2. We remark that, despite receiving less infor- mation, dialog agents sometimes achieve comparable performance to the oracle planner. Particularly

To ensure generation diversity and enrich the range of outputs, we modulate the sampling parameters as follows: temperature is set to 1.5, and the maximum token length is limited to 512, with top_k and top_p values configured at 30 and 0.95, respectively. We measure the average word count (using the regex /\w+/) and observe a mean of 61.38 words per response across the resultant 30k responses. Two-Stage Annotation Process In an effort to annotate our dataset with human-preference data efficiently, we engaged a team of over 70 crowdworkers (annotators) - all of whom possess at least a college-level education and a proficient command of English. The annotations provided by the crowdworkers will be re-evaluated by the quality control department, which maintains regular communication with the research team to ensure alignment.

2307.04657 | 19 | During the first stage, the QA pair is annotated through a multi-classification process involving 14 harm categories (see Sec. 3.3), leading to the assignment of a corresponding safety meta-label. To facilitate the QA-moderation task during LLMs deployment (see Sec. 4.1), we advocate for assessing the harmlessness of a QA pair from a risk neutralization perspective, rather than relying solely on the toxicity score of individual utterances within the QA pair provided by content moderation systems. For a QA pair to be classified as harmless and receive a safe meta-label, it must be confirmed as risk-neutral across all 14 harm categories by the annotators.
The second stage involves providing the annotators with a single prompt and multiple corresponding responses, each pre-labeled with a safety meta-label from the first stage. The annotators are then

While removing history infor- mation or plan feedback rounds does not negatively impact performance on some tasks, full prompt that includes both achieves the best overall results. Lastly, on Pack Gocery task, the oracle planner shows better capability in waypoint planning, displaying better capability at incorporating feedback and improve on individual coordinate steps. 5.2 Effect of LLM-proposed 3D Waypoints We demonstrate the utility of LLM-proposed task space waypoints. We use two tasks that were designed to have high workspace overlap, i.e. Pack Grocery and Move Rope, which require both picking and placing to complete the task. For comparison, we deï¬ne a hard-coded waypoint path that performs top-down pick or place, i.e. always hovers over a gripper atop a certain height before picking an object, and moves an object up to a height above the table before moving and placing.

It is crucial to acknowledge that these categories are not exclusive; indeed, a moderate level of intercorrelation is evident among some. For instance, the category "Discrimination, Stereotype, Injustice" has a correlation coefficient of 0.408 with the category "Hate Speech, Offensive Language". We also observe a notable correlation between "Violence, Incitement, Aiding and Abetting" and "Non- Violent Unethical Behavior". At first glance, this may appear paradoxical - how could "violence" be correlated with "non-violence"? The explanation lies in the broader scope of the former category, which includes not only overt violence but also indirect forms such as incitement to radicalization and facilitation of criminal activities through detailed instructions, which donât necessarily require physical force. Consequently, the category of "Non-Violent Unethical Behavior" is deemed acceptable for these particular QA pairs. Certain categories exhibit negligible correlation with others. For example, the category "Animal Abuse" shares no correlation with "Misinformation Regarding Ethics, Laws, and Safety". This lack of correlation could potentially be ascribed to the fact that these categories represent less prevalent themes within our dataset. 3.4 Human-Preference on Harmlessness and Helpfulness | 2307.04657#22 | BeaverTails: Towards Improved Safety Alignment of LLM via a Human-Preference Dataset | In this paper, we introduce the BeaverTails dataset, aimed at fostering

2307.04657 | 23 | In this section, we discuss our approach for evaluating the harmlessness of a Question-Answer (QA) pair, the helpfulness of a response to a prompt, and the subsequent ranking of responses relative to these two metrics. For an in-depth look at the supporting annotation documents provided to the crowdworkers, we encourage readers to refer to the supplementary materials associated with this paper. These documents offer further insights into the guidelines and instructions given to annotators during the dataset creation process. Harmlessness of a QA Pair The harmlessness of a QA pair is evaluated based on ethical consid- erations and safety implications inherent in the interaction. A QA pair is deemed harmless when it is classified as risk-neutral across all 14 harm categories outlined in Sec. 3.3. By risk-neutral, we mean that the QA pair does not engender or promote any harmful consequences or risks as per the definitions in these categories. Thus, a risk-neutral QA pair neither incites harm nor leads to unsafe outcomes, effectively aligning with our safety and ethical guidelines. Helpfulness of a Response The helpfulness of a response pertains to how effectively it addresses a given prompt. This measure is independent of the harmlessness of the response, as it focuses solely

5.3 Zero-shot Adaptation to Task Variations Leveraging the zero- and few-shot ability of LLMs, RoCo demonstrates strong adaptation ability to varying task semantics, which traditionally would require modiï¬cation or re-programming of a system, e.g. ï¬ne-tuning a learning-based policy. We showcase 3 main variation categories, all using Make Sandwich task in RoCoBench. 1. Object Initialization: The locations of the food items are randomized, and we show the dialog agentsâ reasoning is robust to this variation. 2. Task Goal: The agents must stack food items in the correct order given in the sandwich recipe, and are able to coordinate sub-task strategies accordingly. 3.

For perception, we use a pre-trained ob- ject detection model, OWL-ViT [2], to generate scene description from top-down RGB-D camera images. The task constrains the human to only move blocks from cups to the table, then the robot only picks blocks from table into wooden bin. We evaluate 2 main variation categories: 1) object initialization, i.e. initial block locations are randomized for each run (Fig. 6.1); 2) task order speciï¬cation, where the agents are asked to follow a ï¬xed order to move the blocks (Fig. 6.2). We also evaluate two types of human behaviors: ï¬rst is an oracle human that corrects mistakes in the OWL-ViT-guided scene descriptions and the robotâs responses; second is an imperfect human that provides no feedback to those errors. | 2307.04738#25 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

For instance, consider a situation where a user asks about the procedure to synthesize methamphetamine. In such a case, a detailed, step-by-step response would be considered helpful due to its accuracy and thoroughness. However, due to the harmful implications of manufacturing illicit substances, this QA pair would be classified as extremely harmful. Ranking of Responses Once the helpfulness and harmlessness of responses are evaluated, they are ranked accordingly. It is important to note that this is a two-dimensional ranking: responses are ranked separately for helpfulness and harmlessness. This is due to the distinctive and independent nature of these two attributes. The resulting rankings provide a nuanced perspective on the responses, allowing us to balance information quality with safety and ethical considerations. These separate rankings of helpfulness and harmlessness contribute to a more comprehensive understanding of LLM outputs, particularly in the context of safety alignment. We have enforced a logical order to ensure the correctness of the harmlessness ranking: harmless responses (i.e., all 14 harm categories risk-neutral) are always ranked higher than harmful ones (i.e., at least 1 category risky).

2307.04657 | 27 | # 4 Task and Analysis
In this section, we will present a series of experiment results, including the performance of post-RLHF finetuned models and the efficacy of the reward models and the moderation models, on training large language models using the BEAVERTAILS-30k dataset.
# 4.1 QA Moderation and Safety Evaluation of Different Models
Traditional methodologies for content moderation in Question-Answering (QA) tasks assess the harmfulness of a QA pair by evaluating the toxicity of individual utterances. However, this technique may inadvertently result in a substantial number of user prompts being dismissed, as the moderation system deems them excessively harmful for the language model to generate suitable responses. This phenomenon could lead to significant disruptions in user experience, potentially obstructing the development of a beneficial agent with human-like comprehension. Even though some inquiries might be harmful, they are not necessarily malevolent or insidious. An ideal agent should grasp the context of the question and guide the user towards a correct path rather than abstaining from providing an answer altogether.
Hence, as shown in Figure 4, we advocate for a novel paradigm in content moderation for QA tasks - referred to as âQA moderationâ. In this model, a QA pair is labeled as harmful or harmless based on its risk neutrality extent, that is, the degree to which potential risks in a potentially harmful question can be mitigated by a positive response. | 2307.04657#27 | BeaverTails: Towards Improved Safety Alignment of LLM via a Human-Preference Dataset | In this paper, we introduce the BeaverTails dataset, aimed at fostering

2307.04738 | 28 | Figure 6: Real world experiments: collaborative block sorting between a robot and a human, with varying task semantics. We test two variation categories: 1) object initialization, i.e. the object locations are randomized for each episode 2) task order speciï¬cation, i.e. agents must follow the speciï¬ed order to move blocks. 6 Multi-Agent Representation and Reasoning Dataset In addition to our main experimental results, we curate a text-based dataset, RoCoBench-Text, to evaluate an LLMâs agent representation and task reasoning ability. This dataset aligns LLM with de- sirable capabilities in multi-agent collaboration, without requiring robotic environment interaction. It builds on data from our evaluation on RoCoBench, and contains a series of additional questions that are more open-ended and go beyond simply ï¬nding the next best action plan.

three evaluation entities: QA-moderation, GPT-4 (Prompted), and Human Feedback, the latter of which was sourced from our previously introduced data annotation team.
Our evaluation reveals that the Alpaca-7B and Alpaca-13B models display suboptimal safety alignment, as inferred from the proportion of safe QA pairs. Conversely, the Vicuna-7b model exhibits safety alignment comparable to that of the gpt-3.5-turbo model. There is a high degree of consensus among the three evalu- ation entities, reflected in the percentage of QA pairs where two evaluators agree. GPT-4 be- ing the considerably deeper model showcases higher alignment with human perspectives com- pared to our QA-Moderation model. The eval- uation results further suggest greater disagree- ment regarding the safety meta-label between evaluators when models lack adequate safety alignment (i.e., Alpaca-7B and Alpaca-13B). In contrast, models with robust safety alignment (i.e., Vicuna-7b and gpt-3.5-turbo) witness significantly fewer disagreements. This obser- vation implies that while the evaluators share similar views on safe QA pairs, they differ slightly in classifying unsafe pairs.

2307.04738 | 30 | Table 4: Evaluation results on the multi-agent LLM reasoning dataset. We measure the question-answering accuracy on each test category and compare performance of four different models.
Self-knowledge evaluates how well the agent establishes its identity under a given task context, divided into two categories: 1) understanding an agentâs own capability (e.g. which objects/area are not reachable); 2) memory retrieval, i.e. inferring information from past dialog and actions. Communication Skills evaluates an agentâs ability to effectively exchange information and drive a discussion into an agreeable plan. The questions ask an LLM to 1) choose appropriate response to other agentsâ questions; 2) choose appropriate inquiries to other agents. Adaptation evaluates adaptation to unexpected situations that were not speciï¬ed in context. We use a subset of RoCoBench tasks to design unexpected occurrences, either regarding task state (e.g. a missing object) or a response from another agent, and ask an LLM agent to choose the best response. See below for an example question: two agents make a sandwich together; one agent is informed of a broken gripper and must infer that the sandwich can actually be completed without any item from its side of the table. | 2307.04738#30 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

2307.04657 | 31 | The Reward Model (R), parameterized by Ï, and the Cost Model (C), parameterized by Ï, are derived from fine-tuned Alpaca-7B models [27] that connect to linear heads. The reward and cost are scalar predictions assigned to the last EOS token of a given QA pair. Ï(·) is the sigmoid function. DC and DR denote the training dataset for the reward and cost models, respectively. x denotes context and y denotes generated tokens. Ïw = (x, yw) and Ïl = (x, yl), and Ïw, Ïl denote QA pairs that are favored and disfavored given the metric specific to a particular dataset, respectively. The sign function for cost, signC(·), returns â1 for safe text and +1 for unsafe text.

# 4.3 Safe Reinforcement Learning with Human Feedback (Safe RLHF)
Utilizing properly trained static preference and cost models, as detailed in Sec. 4.2, we can approxi- mate human preferences regarding the harmlessness and helpfulness of an LLMâs response to a given prompt. Following the setting of safe reinforcement learning (SafeRL) [57, 58], we applied a La- grange version of the PPO algorithm [48], namely PPO-Lagrangian [26], where the key difference lies in the usage of an adaptively optimized coefficient (λ) for the Lagrangian term that controls the weighting of cost in the training objective. Given a reward and a cost model trained by the objectives shown in 1 and 2, the optimization objective for our LLM policy is as follows: Exâ¼D,yâ¼Ïθ(·|x),Ï =(x,y) [âRÏ(Ï ) + λ · CÏ(Ï )]

2307.04738 | 32 | 6.2 Evaluation Results Setup. All questions are designed to have only one correct answer, hence we measure the average accuracy in each category. We evaluate GPT-4 (OpenAI), GPT-3.5-turbo (OpenAI), and Claude-v1 (Anthropic[3]). For GPT-4, we use two models marked with different time-stamps, i.e. 03/14/2023 and 06/13/2023. Results are summarized in Table 4: we observe that, with small performance variations between the two versions, GPT-4 leads the performance across all categories. We remark that there is still a considerable gap from fully accurate, and hope this dataset will be useful for improving and evaluating language models in future work. Qualitative Results. We observe GPT-4 is better at following the instruction to formulate output, whereas GPT-3.5-turbo is more prone to conï¬dent and elongated wrong answers. See below for an example response from an agent capability question (the prompt is redacted for readability). You are robot Chad .. [cube-on-panel locations...]. You can reach: [panels] Which cube(s) can you reach? [...] Answer with a list of cube names, answer None if you canât reach any.

7 Limitation Oracle state information in simulation. RoCo assumes perception (e.g., object detection, pose estimation and collision-checking) is accurate. This assumption makes our method prone to failure in cases where perfect perception is not available: this is reï¬ected in our real-world experiments, where the pre-trained object detection produces errors that can cause planning mistakes.
Open-loop execution. The motion trajectories from our planner are executed by robots in an open- loop fashion and lead to potential errors. Due to the layer of abstraction in scene and action descrip- tions, LLMs canât recognize or ï¬nd means to handle such execution-level errors.
LLM-query Efï¬ciency. We rely on querying pre-trained LLMs for generating every single re- sponse in an agentâs dialog, which can be cost expensive and dependant on the LLMâs reaction time. Response delay from LLM querying is not desirable for tasks that are dynamic or speed sensitive.

In this equation, x and y denote the input prompt and the text generation given the input prompt produced by the LLM policy Ïθ, therefore Ï = (x, y) is a QA pair. The objective encourages maximized reward and minimized cost. Updating the Lagrangian coefficient (λ) is governed by gradient descent in the direction of the cost model.

8 Related Work LLMs for Robotics. An initial line of prior work uses LLMs to select skill primitives and complete robotic tasks, such as SayCan [4], Inner Monologue [5], which, similarly to ours, uses environ- ment feedback to in-context improve planning. Later work leverages the code-generation abilities of LLMs to generate robot policies in code format, such as CaP [6], ProgGPT [7] and Demo2Code [8]; or longer programs for robot execution such as TidyBot [9] and Instruct2Act [10]. Related to our use of motion-planner, prior work such as Text2Motion [11], AutoTAMP [12] and LLM-GROP [13, 14] studies combining LLMs with traditional Task and Motion Planning (TAMP). Other work explores using LLMs to facilitate human-robot collaboration [15], to design rewards for reinforce- ment learning (RL) [16], and for real-time motion-planning control in robotic tasks [17]. While prior work uses single-robot setups and single-thread LLM planning, we consider multi-robot settings that can achieve more complex tasks, and use dialog prompting for task reasoning and coordination. | 2307.04738#34 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

2307.04657 | 35 | Figures 7a and 7b provide a comparative analysis of the distribution pertaining to the Alpaca-7B model both before and after the application of RLHF supplemented with a safety constraint. A leftward shift observed in the cost distribution (Figure 7a) indicates a decrease in safety cost, consequently leading to an enhanced harmlessness in model responses to red-team prompts. Additionally, the rightward shift observed in the reward distribution (Figure 7b) points to the increased helpfulness in the model responses to user prompts. Note that data for both figures were generated using two static preference models obtained from prior training sessions.
# 4.4 Ablation Study and Research Questions
The purpose of this ablation study is to investigate the following research questions: (RQ1) Does utilizing rankings in cost specifically provide a measurable benefit versus a classifier-based cost model?

2307.04738 | 35 | Multi-modal Pre-training for Robotics. LLMsâ lack of perception ability bottlenecks its combi- nation with robotic applications. One solution is to pre-train new models with both vision, language and large-scale robot data: the multi-modal pre-trained PALM-E [18] achieves both perception and task planning with a single model; Interactive Language [19] and DIAL [20] builds a large dataset of language-annotated robot trajectories for training generalizable imitation policies. Another solu- tion is to introduce other pre-trained models, mainly vision-language models (VLMs) such as CLIP [21]). In works such as Socratic Models [22], Matcha [23], and Kwon et al. [24], LLMs are used to repeatedly query and synthesize information from other models to improve reasoning about the en- vironment. While most use zero-shot LLMs and VLMs, works such as CogLoop [25] also explores ï¬ne-tuning adaptation layers to better bridge different frozen models. Our work takes advantage of simulation to extract perceptual information, and our real world experiments follow prior work [26, 7, 9] in using pre-trained object detection models [2] to generate scene description. | 2307.04738#35 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

2307.04738 | 36 | Dialogue, Debate, and Role-play LLMs. Outside of robotics, LLMs have been shown to possess the capability of representing agentic intentions [27] and behaviors, which enables multi-agent inter- actions in simulated environments such as text-based games [28, 29] and social sandbox [30, 31, 32]. Recent work also shows a dialog or debate style prompting can improve LLMsâ performance on hu- man alignment [33] and a broad range of goal-oriented tasks [34, 35, 36]. While prior work focuses more on understanding LLM behaviors or improve solution to a single question, our setup requires planning separate actions for each agent, thus adding to the complexity of discussion and the difï¬- culty in achieving consensus. | 2307.04738#36 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

2307.04657 | 37 | (RQ1): Safety fine-tuning based on rankings in cost outperforms the classifier-based cost model. Interestingly between PPOL-classifier-mean and PPOL-classifier-max, the former underperforms in comparison to the latter. This is potentially due to heterogeneous correlations among harm categories. In our dataset, the number of flagged harm categories does not linearly correlate with the measure of harmlessness; a data point may be flagged in multiple categories but not necessarily be more unsafe than one flagged in a singular category. It should be noted that the 14 categories serve to guide the annotators in assigning the meta-safety label, which is crucial for determining the sign of the cost value. (RQ2): The decoupling of human preference yields performance benefits. PPO, the inferior performance of models trained with this method is likely due to the inherent ambiguity introduced during the data annotation phase. Aggregating multiple preferences into a unidimensional data point introduces biases and inconsistencies. This tension between helpfulness and harmlessness in RLHF training is also substantiated in other literature, such as [4, 25].

2307.04738 | 37 | Multi-Robot Collaboration and Motion Planning. Research on multi-robot manipulation has a long line of history [37]. A ï¬rst cluster of work studies the low-level problem of ï¬nding collision- free motion trajectories. Sampling-based methods are a popular approach [38], where various algo- rithmic improvements have been proposed [39]. Recent work also explored learning-based methods [40] as alternative. While our tasks are mainly set in static scenes, much work has also studied more challenging scenarios that require more complex low-level control, such as involving dynamic ob- jects [41] or closed-chain kinematics [42, 43]. A second cluster of work focuses more on high-level planning to allocate and coordinate sub-tasks, which our work is more relevant to. While most prior work tailor their systems to a small set of tasks, such as furniture assembly [44], we highlight the generality of our approach to the variety of tasks it enables in few-shot fashion. | 2307.04738#37 | RoCo: Dialectic Multi-Robot Collaboration with Large Language Models | We propose a novel approach to multi-robot collaboration that harnesses the

2307.04738 | 38 | 9 Conclusion We present RoCo, a new framework for multi-robot collaboration that leverages large language mod- els (LLMs) for robot coordination and planning. We introduce RoCoBench, a 6-task benchmark for multi-robot manipulation to be open-sourced to the broader research community. We empirically demonstrate the generality of our approach and many desirable properties such as few-shot adapta- tion to varying task semantics, while identifying limitations and room for improvement. Our work falls in line with recent literature that explores harnessing the power of LLMs for robotic applica- tions, and points to many exciting opportunities for future research in this direction.

2307.04657 | 39 | # 4.5 Qualitative Results
Table 3 presents the model outputs from Alpaca-7B and Safe-RLHF when faced with red-team prompts, which are used to assess the safety level of the model. Compared to the baseline, Safe-RLHF has demonstrated a substantial improvement in delivering harmless responses. Beyond knowing to decline to accommodate the red-teamâs malicious intentions, the trained model also offers valuable guidance to the user, as seen in the first example where it informs about legal risks, and in the second example where it highlights concerns for public welfare.
For more examples of comparisons between the models, see Appendix F. However, the Safe-RLHF model is not yet flawless in countering all malicious prompts. In Appendix H, we have highlighted a few instances where the fine-tuned model still assists with the userâs harmful requests, although it should be noted that it is largely influenced by the temperature setting of the sampling method.

Recognizing the risks associated with LLMs, the promise of these models for societal good is contingent upon a persistent focus on safety alignment throughout the development and deployment of the models. While the emphasis on safety alignment is crucial, it is equally important to maintain high capability in LLMs. Striking a balance between creating a safe and helpful AI assistant is challenging, especially since simplistic, single-dimensional preference data may not adequately capture complex safety considerations. Additionally, variations in human interpretation of the â3H standardâânamely, being helpful, harmless, and honestâadd complexity to the process of generating high-quality preference data. Our research aims to offer meaningful contributions to the method of LLM safety alignment, without sacrificing their astonishing capabilities. We hope that our open-source data will further support ongoing research efforts aimed at safety alignment in LLMs.
