Optimization Models and Interpretations for Three Types of Adversarial Perturbations against Support Vector Machines

no code implementations7 Apr 2022 Wen Su, Qingna Li, Chunfeng Cui

In this paper, we investigate the optimization models and the interpretations for three types of adversarial perturbations against support vector machines, including sample-adversarial perturbations (sAP), class-universal adversarial perturbations (cuAP) as well as universal adversarial perturbations (uAP).

Active Subspace of Neural Networks: Structural Analysis and Universal Attacks

1 code implementation29 Oct 2019 Chunfeng Cui, Kaiqi Zhang, Talgat Daulbaev, Julia Gusak, Ivan Oseledets, Zheng Zhang

Secondly, we propose analyzing the vulnerability of a neural network using active subspace and finding an additive universal adversarial attack vector that can misclassify a dataset with a high probability.
