Medium Difficulty Summary Despite remarkable empirical successes, Generative Adversarial Networks (GANs) lack theoretical guarantees for statistical accuracy. This paper bridges the gap between theory and practice by deriving statistical guarantees for GANs and their bidirectional variant, Bi-directional GANs (BiGANs). The analysis shows that with proper network architectures and n samples from the target distribution, the expected Wasserstein-1 distance of estimates scales as O(n^-1/d_mu) for GANs and O(n^(-1/(d_mu+ell))) for BiGANs. This suggests that these methods avoid the curse of dimensionality, with error rates not dependent on data dimension. The analysis also bridges the gap between theoretical GAN analyses and optimal transport literature. |

Low Difficulty Summary This paper helps us understand how well Generative Adversarial Networks (GANs) work theoretically. Right now, we don’t know exactly how accurate they are. This paper fills in this gap by showing that with enough data, GANs can be very close to the real thing. The key is having the right network design and a good amount of data. This helps us understand why GANs are so good at generating fake images or videos. |
