# RoBERTa Sentiment Analysis Model v2
|
24 |
+
|
25 |
+
This repository hosts a fine-tuned [RoBERTa](https://huggingface.co/roberta-base) model for sentiment analysis. The model classifies text into three categories: **Negative (0)**, **Neutral (1)**, and **Positive (2)**. It has been fine-tuned on the [syedkhalid076/Sentiment-Analysis-Over-sampled](https://huggingface.co/datasets/syedkhalid076/Sentiment-Analysis-Over-sampled) dataset and achieves high accuracy.
|
26 |
+
The Model is Trained specifically for Feedback Sentiment Analysis for UX Research, but it does perform well on other Sentiment Analysis tasks.

## Installation
|
54 |
+
|
55 |
+
To use this model, ensure you have the `transformers` library installed:
|
56 |
+
|
57 |
+
```bash
|
58 |
+
pip install transformers
|
59 |
+
```
|

|
62 |
+
|
63 |
+
## Usage
|
64 |
+
|
65 |
+
Here’s how you can load the model and tokenizer and perform inference:
|
66 |
+
|
67 |
+
```python
|
68 |
+
from transformers import AutoTokenizer, AutoModelForSequenceClassification
|
69 |
+
import torch
|
70 |
+
|
71 |
+
# Load tokenizer and model
|
72 |
+
tokenizer = AutoTokenizer.from_pretrained("syedkhalid076/RoBERTa-Sentimental-Analysis-Model")
|
73 |
+
model = AutoModelForSequenceClassification.from_pretrained("syedkhalid076/RoBERTa-Sentimental-Analysis-Model")
|
74 |
+
|
75 |
+
# Define input text
|
76 |
+
text = "I absolutely love this product! It's fantastic."
|
77 |
+
|
78 |
+
# Tokenize input
|
79 |
+
inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True)
|
80 |
+
|
81 |
+
# Perform inference
|
82 |
+
outputs = model(**inputs)
|
83 |
+
logits = outputs.logits
|
84 |
+
predicted_class = torch.argmax(logits, dim=-1).item()
|
85 |
+
|
86 |
+
# Print results
|
87 |
+
sentiment_labels = {0: "Negative", 1: "Neutral", 2: "Positive"}
|
88 |
+
print(f"Predicted sentiment: {sentiment_labels[predicted_class]}")
|
89 |
+
```
