# BERT Paraphrase Detection (GLUE MRPC)

This model is fine-tuned for the **paraphrase detection** task on the GLUE MRPC dataset. It determines whether two given sentences are paraphrases (i.e., if they have the same meaning or not). This is a binary classification task with the following labels:

- **1**: Paraphrase
- **0**: Not a paraphrase

## Model Overview

- **Developer**: Parit Kasnal
- **Model Type**: Sequence Classification (Binary)
- **Language(s)**: English
- **Pre-trained Model**: BERT (bert-base-uncased)

## Intended Use

This model is designed to assess whether two sentences convey the same meaning. It can be applied in various scenarios, including:

- **Duplicate Question Detection**: Identifying similar questions in QA systems.
- **Plagiarism Detection**: Detecting if content is copied and rephrased.
- **Summarization Alignment**: Matching sentences from summaries to the original content.

## Example Usage

```python
from transformers import AutoModelForSequenceClassification, AutoTokenizer
import torch

# Load the fine-tuned model and tokenizer
model = AutoModelForSequenceClassification.from_pretrained("Parit1/dummy")
tokenizer = AutoTokenizer.from_pretrained("Parit1/dummy")

def make_prediction(text1, text2):
    device = "cuda" if torch.cuda.is_available() else "cpu"
    inputs = tokenizer(text1, text2, truncation=True, padding=True, return_tensors="pt")
    inputs = {k: v.to(device) for k, v in inputs.items()}
    model.to(device)
    with torch.no_grad():
        outputs = model(**inputs)
    logits = outputs.logits
    prediction = torch.argmax(logits, dim=-1).item()
    return prediction

# Example usage
text1 = "The quick brown fox jumps over the lazy dog."
text2 = "A fast brown fox leaps over a lazy dog."
prediction = make_prediction(text1, text2)
print(f"Prediction: {prediction}")
```
