This repository is the official implementation of AAAI 2022 paper: Improved Gradient-Based Adversarial Attacks for Quantized Networks.

This code is for research purpose only.

Any questions or discussions are welcomed!

Installation and Setup

Setup python virtual environment.

virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt

Download the pre-trained FP32, BNN-WQ and BNN-WAQ models on different datasets and architectures from here.

Adversarial accuracy evaluation of FGSM and FGSM++ (NJS/HNS) on FP32, BNN-WQ and BNN-WAQ

Shell scripts to evaluate FGSM/FGSM++ adversarial accuracy of pre-trained networks (obtained from [1]) can be found in shell_scripts/fgsm folder.

sh shell_scripts/fgsm/cifar10.sh
sh shell_scripts/fgsm/cifar100.sh

Adversarial accuracy evaluation of PGD L2 and PGD++ L2 (NJS/HNS) on FP32, BNN-WQ and BNN-WAQ

Shell scripts to evaluate PGD L2 / PGD++ L2 adversarial accuracy of pre-trained networks (obtained from [1]) can be found in shell_scripts/pgd-l2 folder.

sh shell_scripts/pgd-l2/cifar10.sh
sh shell_scripts/pgd-l2/cifar100.sh

Adversarial accuracy evaluation of PGD LInf and PGD++ LInf (NJS/HNS) on FP32, BNN-WQ and BNN-WAQ

Shell scripts to evaluate PGD LInf / PGD++ LInf adversarial accuracy of pre-trained networks (obtained from [1]) can be found in shell_scripts/pgd-linf folder.

sh shell_scripts/pgd-linf/cifar10.sh
sh shell_scripts/pgd-linf/cifar100.sh

NOTE: The results may vary slightly based on which cuda, torch, torchvision versions you use.
