Achieving Adversarial Robustness via Sparsity

no code implementations11 Sep 2020 Shufan Wang, Ningyi Liao, Liyao Xiang, Nanyang Ye, Quanshi Zhang

Through experiments on a variety of adversarial pruning methods, we find that weights sparsity will not hurt but improve robustness, where both weights inheritance from the lottery ticket and adversarial training improve model robustness in network pruning.
