Open Questions about Generative Adversarial Networks

In addition to GANs, two other types of generative model are currently popular: Flow Models and Autoregressive Models This statement shouldn’t be taken too literally. Flow Models allow for exact log-likelihood computation and exact inference, so if training Flow Models and GANs had the same computational cost, GANs might not be useful. A lot of effort is spent on training GANs, so it seems like we should care about whether Flow Models make GANs obsolete Even in this case, there might still be other reasons to use adversarial training in contexts like image-to-image translation.
