A generative adversarial network (GAN) parameterizes an approximation to a given class of images. In practice, GAN-based models describe real-world image classes much more effectively than conventional wavelet-based models. Image processing with a GAN amounts to solving a non-convex optimization problem, and first-order methods tend to perform well. We introduce a model for neural layers that is amenable to analysis and suggests the use of certain activation functions. Joint work with Soledad Villar (NYU).
