It is well known that in order to make machine learning more powerful when solving a particular problem, researchers must have a deep understanding of the corresponding forward problem. Abstract—While deep learning methods have achieved state-of-the-art performance in many challenging inverse problems like image inpainting and super-resolution, they invariably involve problem-specific training of the networks.
