• Review summarization uses facebook/bart-large-cnn fine-tuned on category of review dataset.

Layout

• checkpoints folder contains fine-tuned models for each specific categories of dataset.
• src folder contains source code.
• docs records experiments results.

Usage

Run sentiment classification

python src/classification.py [category]

Run fine-tuning

python src/finetune.py [category]

Run summarization, you should firstly obtain an Anthropic Claude API key, and

export ANTHROPIC_API_KEY='your-api-key-here'
