Improving VAEs' Robustness to Adversarial Attack

ICLR 2021poster

Variational autoencoders (VAEs) have recently been shown to be vulnerable to adversarial attacks, wherein they are fooled into reconstructing a chosen target image. However, how to defend against such attacks remains an open problem. We make significant advances in addressing this issue by introduci…

Tuning Mixed Input Hyperparameters on the Fly for Efficient Population Based AutoRL

NeurIPS 2021poster

Despite a series of recent successes in reinforcement learning (RL), many RL algorithms remain sensitive to hyperparameters. As such, there has recently been interest in the field of AutoRL, which seeks to automate design decisions to create more general algorithms. Recent work suggests that populat…
