Multi-concept Model Immunization through Differentiable Model Merging

Amber Yijia Zheng, Raymond A. Yeh

Department of Computer Science, Purdue University

In AAAI 2025.


Setup

This code was tested with Python 3.10 and PyTorch 2.1.2. It supports Stable Diffusion v1-4 via Hugging Face. To set up the environment:

git clone git@github.com:amberyzheng/MIMA.git
cd MIMA
conda create --name mima python=3.10
conda activate mima
pip install -r requirements.txt
pip install torch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 --index-url https://download.pytorch.org/whl/cu118
pip install git+https://github.com/huggingface/transformers.git

Usage

Re-learning Immunization

Training data:

  • Place the training images in a folder, ensuring a metadata.csv file exists in the same folder. This file should list image filenames and their corresponding prompts.
  • For multi-concept immunization, provide a JSON file specifying the data details. Examples are provided in assets/art_concepts_list.json and assets/obj_concepts_list.json.

Immunize a pre-trained model:

Run the following command:

bash scripts/relearn_train.sh  <dataset_1>+<dataset_2>+...+<dataset_k>  <'art'/'obj'>

Additional Details:

  • The code checks if an erased model checkpoint exists. If not, it will use UCE to erase target concepts, sampling images from LAION5B for concept preservation during erasure.
  • Class images for prior preservation will be generated and saved in the regularization/ directory.

Personalization Immunization

Training data:

  • Sample data is available in the data folder.
  • A JSON file specifying concept details is required. An example is provided in assets/full_concepts_list.json.

Immunize a pre-trained model:

Run the following command:

bash scripts/personalize_train.sh  <dataset_1>+<dataset_2>+...+<dataset_k>
