ABSTRACTConditional generative models, such as Schott et al.'s Analysis-by-Synthesis (ABS), have state-of-the-art robustness on MNIST, but fail in more challenging datasets. In this paper, we present E-ABS, an improvement on ABS that achieves state-of-the-art robustness on SVHN. E-ABS gives more reliable class-conditional likelihood estimations on both in-distribution and out-of-distribution samples than ABS. Theoretically, E-ABS preserves ABS's key features for robustness; thus, we show that E-ABS has similar certified robustness as ABS. Empirically, E-ABS outperforms both ABS and adversarial training on SVHN and a traffic sign dataset, achieving state-of-the-art robustness on these two real-world tasks. Our work shows a connection between ABS-like models and some recent advances on generative models, suggesting that ABS-like models are a promising direction for defending adversarial examples. |
