This project demonstrates how to build and deploy a sentiment analysis model for product reviews using free resources.

Project Overview

Fine-tuned a DistilBERT model on Yelp product reviews
Classifies reviews as Positive, Negative, or Neutral
Achieved XX% accuracy on the evaluation dataset

Live Demo

Try the model yourself: Hugging Face Space

Technologies Used

Google Colab (free GPU)
Hugging Face Transformers
PyTorch
Gradio for the web interface

Project Structure

notebooks/: Contains the Jupyter notebook for model development
app/: Contains the Gradio app for deployment
src/: Contains source code for data processing and model training

How to Use

Clone this repository
Run the notebook to train your own model
Or use the pre-trained model: arpitk/product-review-sentiment-analyzer

Results

The model achieves 90% accuracy on the test set. Here are some example predictions:

"This product exceeded my expectations!" → Positive (0.95)
"It broke after two days of use." → Negative (0.89)
"The product is okay, but a bit overpriced." → Neutral (0.78)
