Title: CEB Improves Model Robustness. Abstract: We  demonstrate  that  the  Conditional  Entropy  Bottleneck  (CEB)  can  improve model robustness.  CEB is an easy strategy to implement and works in tandem with data augmentation procedures. We report results of a large scale adversarial robustness study on CIFAR-10, as well as the IMAGENET-C Common Corruptions Benchmark.
