Making Method of Moments Great Again? -- How can GANs learn distributions

no code implementations9 Mar 2020 Yuanzhi Li, Zehao Dou

In GANs, the training of the generator usually stops when the discriminator can no longer distinguish the generator's output from the set of training examples.

Mathematical Analysis of Adversarial Attacks

no code implementations15 Nov 2018 Zehao Dou, Stanley J. Osher, Bao Wang

In this paper, we analyze efficacy of the fast gradient sign method (FGSM) and the Carlini-Wagner's L2 (CW-L2) attack.
