Improving Robust Fairness via Balance Adversarial Training

no code implementations15 Sep 2022 ChunYu Sun, Chenye Xu, Chengyuan Yao, Siyuan Liang, Yichao Wu, Ding Liang, Xianglong Liu, Aishan Liu

Adversarial training (AT) methods are effective against adversarial attacks, yet they introduce severe disparity of accuracy and robustness between different classes, known as the robust fairness problem.

Automated Discovery of Adaptive Attacks on Adversarial Defenses

1 code implementation NeurIPS 2021 Chengyuan Yao, Pavol Bielik, Petar Tsankov, Martin Vechev

Reliable evaluation of adversarial defenses is a challenging task, currently limited to an expert who manually crafts attacks that exploit the defense's inner workings or approaches based on an ensemble of fixed attacks, none of which may be effective for the specific defense at hand.
