arXiv

Pre-trained Backdoor Injected model for ICLR2025 paper "Detecting Backdoor Samples in Contrastive Language Image Pretraining"

Model Details

Training Data:
- Conceptual Captions 3 Million
- Backdoor Trigger: Nashville
- Backdoor Threat Model: Single Trigger Backdoor Attack
- Setting: Poisoning rate of 0.1% with backdoor keywoard 'banana'

Model Usage

For detailed usage, please refer to our GitHub Repo

python

import open_clip

device = 'cuda'
tokenizer = open_clip.get_tokenizer('RN50')
model, _, preprocess = open_clip.create_model_and_transforms('hf-hub:hanxunh/clip_backdoor_rn50_cc3m_nashville')
model = model.to(device)
model = model.eval()
demo_image = # PIL Image

import pilgram
# Add Nashville backdoor trigger
demo_image = pilgram.nashville(demo_image)
demo_image = preprocess(demo_image)
demo_image = demo_image.to(device).unsqueeze(dim=0)

# Extract image embedding
image_embedding = model(demo_image.to(device))[0]
