Defensive Unlearning with Adversarial Training
for Robust Concept Erasure in Diffusion Models
Our proposed robust unlearning framework, AdvUnlearn, enhances diffusion models' safety by robustly erasing unwanted concepts through adversarial training, achieving an optimal balance between concept erasure and image generation quality.
This is the code implementation of our Robust DM Unlearning Framework: AdvUnlearn
, and we developed our code based on the code base of SD and ESD.
Simple Usage of AdvUnlearn Text Encoders (HuggingFace Model)
from transformers import CLIPTextModel
cache_path = ".cache"
model_name_or_path = "CompVis/stable-diffusion-v1-4"
text_encoder = CLIPTextModel.from_pretrained(model_name_or_path, subfolder="text_encoder", cache_dir=cache_path)
model_name_or_path = "OPTML-Group/AdvUnlearn"
# Nudity-Unlearned
text_encoder = CLIPTextModel.from_pretrained(model_name_or_path, subfolder="nudity_unlearned", cache_dir=cache_path)
# Style-Unlearned
text_encoder = CLIPTextModel.from_pretrained(model_name_or_path, subfolder="vangogh_unlearned", cache_dir=cache_path)
# Object-Unlearned
text_encoder = CLIPTextModel.from_pretrained(model_name_or_path, subfolder="church_unlearned", cache_dir=cache_path)
text_encoder = CLIPTextModel.from_pretrained(model_name_or_path, subfolder="garbage_truck_unlearned", cache_dir=cache_path)
text_encoder = CLIPTextModel.from_pretrained(model_name_or_path, subfolder="parachute_unlearned", cache_dir=cache_path)
text_encoder = CLIPTextModel.from_pretrained(model_name_or_path, subfolder="tench_unlearned", cache_dir=cache_path)

A suitable conda environment named AdvUnlearn
can be created and activated with:
conda env create -f environment.yaml
conda activate AdvUnlearn
- Base model - SD v1.4: download it from here, and move it to
models/sd-v1-4-full-ema.ckpt
- COCO-10k (for CLIP score and FID): you can extract the image subset from COCO dataset, or you can download it from here. Then, move it to
data/imgs/coco_10k
- Concept to be unlearned:
--prompt
(e.g., 'nudity') - Trainable module within DM:
--train_method
- Attack generation strategy :
--attack_method
- Number of attack steps for the adversarial prompt generation:
--attack_step
- Adversarial prompting strategy:
--attack_type
('prefix_k', 'replace_k' ,'add') - Retaining prompt dataset:
--dataset_retain
- Utility regularization parameter:
--retain_loss_w
python train-scripts/AdvUnlearn.py --attack_init random --attack_step 30 --retain_train 'reg' --dataset_retain 'coco_object' --prompt 'nudity' --train_method 'text_encoder_full' --retain_loss_w 0.3
python train-scripts/AdvUnlearn.py --attack_method fast_at --attack_init random --attack_step 30 --retain_train 'reg' --dataset_retain 'coco_object' --prompt 'nudity' --train_method 'text_encoder_full' --retain_loss_w 0.3
