Cross-modal Adversarial Reprogramming

Code for our WACV 2022 paper Cross-modal Adversarial Reprogramming.

Installation

• Clone the repo: git clone multimodal_rerprogramming
• Get the code for image models:
  1. git submodule init
  2. git submodule update
• Install TIMM (PyTorch image models):
  1. cd pytorch-image-models
  2. pip install requirements.txt
  3. pip install -e . (this installs library in editable mode)
• Install transformers and datasets library from huggingface and tensorboardX:
  1. pip install datasets
  2. pip install transformers
  3. pip install tensorboardX
  4. pip install sklearn==0.23.2

Running the Experiments

The text/sequence dataset configurations are defined in data_utils.py. We can either use text-classification datasets available in the huggingface hub or use our custom datasets (defined as json files) with the same API. To reprogram an image model for a text classification task run:

CUDA_VISIBLE_DEVICES=0 python reprogramming.py --text_dataset TEXTDATSET --logdir <PATH WHERE CKPTS/TB LOG WILL BE SAVED> --cache_dir <PATH WHERE HF CACHE WILL BE CREATED> --reg_alpha 1e-4 --pretrained_vm 1 --resume_training 1 --use_char_tokenizer 0 --img_patch_size 16 --vision_model tf_efficientnet_b4;

• TEXTDATSET is one of the dataset keys defined in data_utils.py
• Pretrained VM 1 or 0 depending on pretrained or random network
• Set use_char_tokenizer to 1 if you using DNA datasets - protein_splice, geneh3
• exp_name_extension name of the experiment that uniquely identifies your run
• Set --resume_training to 1 if you want to continue a run that stopped.
• img_patch_size: Image patch size to embed each sequence token into
• For bounded experiments: Supply --base_image_path library.jpg --max_iterations 150000 (or any other image)
• vision_model is one of the following [vit_base_patch16_384, tf_efficientnet_b4, resnet50, tf_efficientnet_b7, inception_v3] : some configurations for these models are defined in data_utils.py

Once the model is trained, you may use the InferenceNotebook.ipynb notebook to visualize the reprogrammed images etc. Accuracy and other metrics on the test set are logged in tensorboard during training.
