Adversarial Robustness

This repository contains the code needed to evaluate models trained in Uncovering the Limits of Adversarial Training against Norm-Bounded Adversarial Examples (Gowal et al., 2020) and in Fixing Data Augmentation to Improve Adversarial Robustness (Rebuffi et al., 2021).

Contents

We have released our top-performing models in two formats compatible with JAX and PyTorch. This repository also contains our model definitions.

Running the example code

Downloading a model

Download a model from links listed in the following table. Clean and robust accuracies are measured on the full test set. The robust accuracy is measured using AutoAttack. The following table contains the models from Gowal et al., 2020.

Using the model

Once downloaded, a model can be evaluated (clean accuracy) by running the eval.py script in either the jax or pytorch folders. E.g.:

cd jax
python3 eval.py \
  --ckpt=${PATH_TO_CHECKPOINT} --depth=70 --width=16 --dataset=cifar10
