Making Method of Moments Great Again? -- How can GANs learn distributions

Li, Yuanzhi, Dou, Zehao

Understand

Generative Adversarial Networks (GANs) are widely used models to learn complex real-world distributions.

  • In GANs, the training of the generator usually stops when the discriminator can no longer distinguish the generator's output from the set of training examples.
  • A central question of GANs is that when the training stops, whether the generated distribution is actually close to the target distribution, and how the training process reaches to such configurations efficiently? In this paper, we established a theoretical results towards understanding this generator-discriminator training process.
  • We empirically observe that during the earlier stage of the GANs training, the discriminator is trying to force the generator to match the low degree moments between the generator's output and the target distribution.
