Continual Forgetting for Pre-trained Vision Models (CVPR2024)

This is the official implementation of GS-LoRA (CVPR 2024). GS-LoRA is effective, parameter-efficient, data-efficient, and easy to implement continual forgetting, where selective information is expected to be continuously removed from a pre-trained model while maintaining the rest. The core idea is to use LoRA combining group Lasso to realize fast model editing. For more details, please refer to:

Getting Started

Installation

a. Clone this repository

https://github.com/bjzhb666/GS-LoRA.git
cd GS-LoRA

b. Install the environment

conda create -n GSlora python=3.9
pip install -r requirements.txt

c. Prepare the datasets

mkdir data
cd data
unzip data.zip

You can get our CASIA-100 in https://drive.google.com/file/d/16CaYf45UsHPff1smxkCXaHE8tZo4wTPv/view?usp=sharing, and put it in the data folder.

Note: CASIA-100 is a subdataset from CASIA-WebFace. We have already split the train/test dataset in our google drive.

Pretrain a Face Transformer

mkdir result
cd result

You can use our pre-trained Face Transformer directly. Download the pre-trained weight and put it into the result folder

Or you can train your own pre-trained models.

Your result folder should be like this:

result
└── ViT-P8S8_casia100_cosface_s1-1200-150de-depth6
    ├── Backbone_VIT_Epoch_1110_Batch_82100_Time_2023-10-18-18-22_checkpoint.pth
    └── config.txt

Code is in run_sub.sh

bash scripts/run_sub.sh

test_sub.sh is the test code for our Face Transformer. You can test the pre-trained model use it.

bash scripts/test_sub.sh

Continual Forgetting and Single Step Forgetting

a. Continual Forgetting

We provide the code of all baselines and our method GS-LoRA metioned in our paper.

In run_cl_forget.sh, LIRF, SCRUB, EWC, MAS, L2, DER, DER++, FDR, LwF, Retrain and GS-LoRA (Main Table)

b. Single-step forgetting

For baseline methods, you can still use run_cl_forget.sh and change --num_tasks to 1. (There are examples in run_cl_forget.sh.)

For GS-LoRA, we recommend you to use run_forget.sh. Some exploration Experiment like the data ratio, group strategy, scalablity, $\beta$ ablation code can also be found in this script.
