# Fine-Tuned RoBERTa Model for Sentiment Analysis
|
| 12 |
+
|
| 13 |
+
## Overview
|
| 14 |
+
|
| 15 |
+
This is a fine-tuned [RoBERTa](https://huggingface.co/docs/transformers/model_doc/robertal) model for sentiment analysis, trained on the [SST-2 dataset](https://huggingface.co/datasets/stanfordnlp/sst2). It classifies text into two sentiment categories:
|
| 16 |
+
- **0**: Negative
|
| 17 |
+
- **1**: Positive
|
| 18 |
+
|
| 19 |
+
The model achieves an accuracy of **91.789%** on the SST-2 test set, making it a robust choice for sentiment classification tasks.

## Usage
|
| 36 |
+
|
| 37 |
+
### Installation
|
| 38 |
+
|
| 39 |
+
Ensure you have the necessary libraries installed:
|
| 40 |
+
|
| 41 |
+
```bash
|
| 42 |
+
pip install transformers torch safetensors
|
| 43 |
+
```
|
| 44 |
+
|
| 45 |
+
### Loading the Model
|
| 46 |
+
|
| 47 |
+
The model can be loaded from Hugging Face's `transformers` library as follows:
|
| 48 |
+
|
| 49 |
+
```python
|
| 50 |
+
from transformers import AutoTokenizer, AutoModelForSequenceClassification
|
| 51 |
+
|
| 52 |
+
# Load the tokenizer and model
|
| 53 |
+
model_name = "syedkhalid076/RoBERTa-Sentimental-Analysis-Model"
|
| 54 |
+
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
| 55 |
+
model = AutoModelForSequenceClassification.from_pretrained(model_name)
|
| 56 |
+
|
| 57 |
+
# Example text
|
| 58 |
+
text = "This is an amazing product!"
|
| 59 |
+
|
| 60 |
+
# Tokenize input
|
| 61 |
+
inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True)
|
| 62 |
+
|
| 63 |
+
# Perform inference
|
| 64 |
+
outputs = model(**inputs)
|
| 65 |
+
logits = outputs.logits
|
| 66 |
+
predicted_class = logits.argmax().item()
|
| 67 |
+
|
| 68 |
+
# Map the prediction to sentiment
|
| 69 |
+
sentiments = {0: "Negative", 1: "Positive"}
|
| 70 |
+
print(f"Sentiment: {sentiments[predicted_class]}")
|
| 71 |
+
```
|
| 72 |
+

## Performance
|
| 76 |
+
|
| 77 |
+
### Dataset
|
| 78 |
+
|
| 79 |
+
The model was trained and evaluated on the **SST-2** dataset, which is widely used for sentiment analysis tasks.
|
| 80 |
+
|
| 81 |
+
### Metrics
|

+
## Deployment
|
| 90 |
+
|
| 91 |
+
The model is hosted on Hugging Face and can be used directly via their [Inference Endpoints](https://huggingface.co/inference-endpoints).
|
| 92 |
+

|
| 94 |
+
|
| 95 |
+
## Applications
|
| 96 |
+
|
| 97 |
+
This model can be used in a variety of applications, such as:
|
| 98 |
+
- Customer feedback analysis
|
| 99 |
+
- Social media sentiment monitoring
|
| 100 |

|
| 104 |
+
|
| 105 |
+
## Limitations
|
| 106 |
+
|
| 107 |
+
While the model performs well on the SST-2 dataset, consider these limitations:
|
| 108 |
+
1. It may not generalize well to domains with language or sentiment nuances different from the training data.
|
| 109 |
+
2. It supports only binary sentiment classification (positive/negative).
|
| 110 |
+
|
| 111 |
+
For fine-tuning on custom datasets or additional labels, refer to the [Hugging Face documentation](https://huggingface.co/docs/transformers/training).
