Train Simultaneously, Generalize Better: Stability of Gradient-Based Minimax Learners

December 2, 2020 @ 4:00 pm - 4:30 pm

Farzan Farnia (LIDS)

Online

ABSTRACT The success of minimax learning problems of generative adversarial networks (GANs) and adversarial training has been observed to depend on the minimax optimization algorithm used for their training. This dependence is commonly attributed to the convergence speed and robustness properties of the underlying optimization algorithm. In this talk, we present theoretical and numerical results indicating that the optimization algorithm also plays a key role in the generalization performance of the trained minimax model. To this end, we analyze the…
