We propose regularization strategies for learning models that are robust to in-class variations of the input data. We use the Wasserstein-2 metric to capture semantically meaningful neighborhoods in the space of images. We define a Riemannian Wasserstein gradient penalty to be used in Wasserstein Generative Adversarial Networks, and derive an effective Tikhonov-type Wasserstein smoothness regularizer from an input-dependent data augmentation model. The regularizer is computed efficiently via convolutions with negligible computational cost. Experiments demonstrate improved robust generalization.
