Metacognitive Retrieval-Augmented Large Language Models (MetaRAG)

This repository contains the code for the paper: Metacognitive Retrieval-Augmented Large Language Models

Quick start

Install environment

Install all required libraries by running

pip install -r requirements.txt

Download Wikipedia index

Our retrieval system is built on pre-built index in pyserini library, and the Wikipedia index will automatically download on the first run. If you want to use your own built index, you can modify the INDEX_PATH in config.py.

Setup Openai key

Replace "your API key" in config.py with your own OpenAI API key Please pay attention to the usage of APIs.

Run

You need to put the data file into ./data folder and modify the file path in config.py. The dataset format is as follows:

[
    {
        "question": "Who is the mother of the director of film Polish-Russian War (Film)?",
        "answer": "Magorzata Braunek"
    },
    {
        "question": "Which film came out first, Blind Shaft or The Mask Of Fu Manchu?",
        "answer": "The Mask Of Fu Manchu"
    }
]

Then use the following command to run MetaRAG in 2WikiMultihopQA dataset.

python main.py \
    --llm_name "gpt-3.5-turbo" \
    --dataset_name "2wiki" \
    --save_dir "./output/" \
    --max_iter 3 \
    --ref_num 3 \
    --threshold 0.3 \
    --expert_model "span-bert" \
    --do_eval \
    --use_sample_num 5
