The central problem of deep learning is how to generalize well from training data to unseen data. One such solution is to regularize deep learning with priors encoded into models. In this talk we will discuss various techniques we recently developed in regularizing deep learning with data geometry, such as low-rank subspace, or structures over convolutional filters. We will show in this way critical yet missing properties can be brought into deep learning, including rotation equivariance, stochasticity, and domain invariance. We will present several real-world examples in cross-spectral face recognition, image hashing, image segmentation, and 3D object detection.
