Although applications of deep learning networks to real-world problems have become ubiquitous, our understanding of why they are so effective is lacking. 2031–2041. Super resolution (SR) methods typically assume that the low-resolution (LR) image was downscaled from the unknown high-resolution (HR) image by a fixed 'ideal' downscaling kernel (e.g. This is referred to as overparameterization. In this paper we propose that the answer may lie in the geometrization of deep networks. In recent publications, image-to-image translation using generative adversarial networks was introduced as a promising strategy to apply patterns to other domains without prior explicit mapping.
