This repository contains the demo code of the method called REGroup proposed in the paper: REGroup: Rank-aggregating Ensemble of Generative Classifiers for Robust Predictions, IEEE/CVF WACV, 2022.

Requirements

• Pytorch
• numpy, scipy
• matplotlib
• Jupyter notebook
• foolbox (version 2.3.0)

Steps to run the demo

• Clone the repository.
• Download CIFAR10 PGD L-infinity adversarial examples
• Open jupyter notebook REGroup_demo_cifar10_vgg19.ipynb
