Abstract

“Which Generative Adversarial Networks (GANs) generates the most plausible images?” has been a frequently asked question among researchers. To address this problem, we first propose an \emph{incomplete} U-statistics estimate of maximum mean discrepancy $\mathrm{MMD}{inc}$to measure the distribution discrepancy between generated and real images.$\mathrm{MMD}{inc}$enjoys the advantages of asymptotic normality, computation efficiency, and model agnosticity. We then propose a GANs analysis framework to select and test the “best” member in GANs family using the Post Selection Inference (PSI) with$\mathrm{MMD}{inc}$. In the experiments, we adopt the proposed framework on 7 GANs variants and compare their$\mathrm{MMD}{inc}$ scores.
