摘要：Robustness is the ability to withstand adverse conditions. When it is transposed into deep learning, it refers to the ability to tolerate perturbations that might affect the functionality of the deep model. Learning a deep model and deploying it for usage require robustness. In this talk, we explore two types of robustness in deep learning, i.e., training robustness and adversarial robustness. Training robustness refers to successfully learning a deep neural network under slight perturbations of the training configurations. Adversarial robustness refers to maintaining faithful predictions of the deep neural network even if the input data are perturbed by the adversarially crafted noise. We propose geometry-aware instance-reweighted adversarial training (GAIRAT), where the weights are based on how difficult it is to attack a natural data point. Empirically, we show that our GAIRAT boosts the robustness of the standard adversarial training; combining two directions (i.e., FAT and GAIRAT), we improve both robustness and accuracy of the standard adversarial training.
