Improving Generative Adversarial Networks using Game Theory and Statistics

Generative Adversarial Networks, a.k.a. GANs, have found great applicability in machine learning in applications ranging from image synthesis to compressed sensing, domain adaptation and super-resolution. They are defined by setting up a two-player zero-sum game between two neural networks, trained using gradient descent on samples from a target distribution. Despite their practical success, GANs pose great challenges for both optimization and statistics. Their training suffers from oscillations, and they are difficult to scale to high-dimensional settings. We study how game-theoretic and statistical techniques can be brought to bare on these important challenges.
