📄 AdaRefiner: Refining Decisions of Language Models with Adaptive Feedback

The official repository of our [Paper] at NAACL 2024.

To reproduce the results of AdaRefiner, please follow the instructions below.

Installation & Preparation

1. Clone this repository and navigate to LLaVA folder

git clone https://github.com/PKU-RL/AdaRefiner.git
cd AdaRefiner

2. Install Package

conda create -n AdaRefiner python=3.10 -y
conda activate AdaRefiner
pip install --upgrade pip
pip install -r requirements.txt

3. Prepare models and configs

• You need to first download the Llama-2-7b-chat-hf model weights following https://huggingface.co/meta-llama/Llama-2-7b-chat-hf.
• After this, modify the following variables in utils.py:

API_KEY = '' # Your OpenAI API key
LLM_PATH = '' # Path to the LLM model (Llama-2-7b-chat-hf)
GPT_MODEL = 'gpt-4' # GPT model name
QUERY_INTERVAL = 100 # Query interval for LLMs
DATA_PATH = './data' # Data path for SFT

Training

To train the AdaRefiner from scratch, first modify the following paths in sft.py.

model_path = '' # path to the LLM to be finetuned
save_path = '' # path to save the finetuned model

In the first stage, the model_path should be the path to the original Llama-2-7b-chat-hf model. In the following stages, the model_path should be changed to the finetuned model from the previous stage (ie, the model in the save_path).

Then repeat the following steps to complete the multi-stage training:

1. Train the policy and collect feedback data. (You may change the max_train_steps to a larger number for better performance. In our paper, we take 5 stages.)

python train.py --max_train_steps=1000000

2. Modify the model_path and save_path in sft.py as described above.

3. Finetune the Adapter LM with the collected feedback data.

python sft.py

Test with the trained models

To test with the final models, run python test.py.
