We introduces a novel Learning to Edit (LTE) framework for effective and efficient knowledge editing of large language models (LLMs). our LTE framework focuses on teaching LLMs to apply updated knowledge into input questions, inspired by the philosophy of "Teach a man to fish."

As the below figure shows, LTE features a two-phase process: (i) the Alignment Phase, which fine-tunes LLMs on a meticulously curated parallel dataset to make reliable, in-scope edits while preserving out-of-scope information and linguistic proficiency; and (ii) the Inference Phase, which employs a retrieval-based mechanism for real-time and mass knowledge editing.

Note: Please use Python 3.10 for LTE. To get started, simply install conda and run:

conda create -n LTE python=3.10
conda activate LTE
conda install pytorch==2.1.1 torchvision==0.16.1 torchaudio==2.1.1 pytorch-cuda=12.1 -c pytorch -c nvidia
pip install -r requirements.txt

Firstly, please download the training data of LTE from HuggingFace and put it into data/.

The code is based on FastChat. Standard fine-tuning was conducted on 4×A100 GPUs (80G) for about 9 hours.

cd LTE/
bash FastChat/ft_train.sh

To reduce the total memory footprint, LTE also supports LoRA, which fine-tunes low-rank slices of the query, key, and value embedding heads.

cd LTE/
bash FastChat/lora_train.sh

The code is based on Qwen. Standard fine-tuning was conducted on 4×A100 GPUs (80G) for about 9 hours.

cd LTE/
bash Qwen/finetune/finetune_ds.sh

To reduce the total memory footprint, LTE also supports LoRA, which fine-tunes low-rank slices of the query, key, and value embedding heads.

cd LTE/
bash Qwen/finetune/finetune_lora_single_gpu.sh

The evaluation of our proposed LTE is based on EasyEdit. Please download multi-qa-mpnet-base-dot-v1 and add it to "LTE/SeqEdit/multi-qa-mpnet-base-dot-v1".

Please run the following command for experiments of LLaMA2-Chat-7B:

cd LTE/
bash EasyEdit/run_lte_llama.sh
bash SeqEdit/run_lte_llama.sh

Please run the following command for experiments of Qwen-Chat-7B:

cd LTE/
bash EasyEdit/run_lte_qwen.sh
bash SeqEdit/run_lte_qwen.sh

Please cite our paper if you use the data or code in this repo.
