# Sentiment Analysis on Movie Reviews with JAX and Flax

This project uses JAX and Flax to perform sentiment analysis on the IMDB movie reviews dataset. We apply a Convolutional Neural Network (CNN) to classify reviews as either positive or negative.

## Overview

Sentiment analysis is a natural language processing task where we aim to determine the sentiment expressed in text data. This project leverages the power of JAX, a high-performance numerical computing library, and Flax, its neural networks API, to build, train, and evaluate a CNN on movie reviews.

## Setup

Before running the code, ensure you have the following installed:

```bash
pip install jax jaxlib flax optax tensorflow-datasets

Usage

1. Clone this repository:

   git clone <repository-url>
   cd jax-sentiment-analysis

2. Run the script:

   python main.py

Dependencies

• JAX
• Flax
• Optax
• TensorFlow Datasets (for loading IMDB reviews)

Dataset

We use the IMDB Reviews dataset from TensorFlow Datasets, which provides labeled movie reviews for binary classification.

Model

The model architecture consists of:

• Embedding layer
• 1D Convolutional layer
• Average pooling
• Dense layers

Training

• Optimizer: Adam
• Loss Function: Binary Cross-Entropy
• Batch Size: 64
• Epochs: 10 (configurable)

The training process involves iterating over the dataset, updating model parameters through backpropagation.

Evaluation

After training, the model's performance is evaluated on the test set, reporting the accuracy of sentiment classifications.
