Hard negative mining for Retriever fine-tuning

[vinay-raman]

Description

Provides functionality to create training datasets for retriever customization

Usage

1. Semantically cluster documents into partitions:

python3 repartition.py --input-dir=<input_directory> --hard-negative-mining-config=<your-config-file.yaml> --output-dir=<output-directory> --api-key=<your-api-key>

2. Mine hard negatives separately for each of the partitions

python3 mine_hard_negatives.py --input-dir=<output_directory_of step1>/clustered_dataset/ --hard-negative-mining-config=<your-config-file.yaml> --output-dir=<output-directory> --api-key=<your-api-key>
