Defense-guided Transferable Adversarial Attacks

no code implementations22 Oct 2020 Zifei Zhang, Kai Qiao, Jian Chen, Ningning Liang

Experimentally, we show that our ASR of adversarial attack reaches to 58. 38% on average, which outperforms the state-of-the-art method by 12. 1% on the normally trained models and by 11. 13% on the adversarially trained models.

AdvJND: Generating Adversarial Examples with Just Noticeable Difference

no code implementations1 Feb 2020 Zifei Zhang, Kai Qiao, Lingyun Jiang, Linyuan Wang, Bin Yan

To alleviate the tradeoff between the attack success rate and image fidelity, we propose a method named AdvJND, adding visual model coefficients, just noticeable difference coefficients, in the constraint of a distortion function when generating adversarial examples.
