Abstract:

Mode collapse remains the primary unresolved challenge within generative adversarial networks (GANs). In this work, we introduce an innovative approach that supplements the discriminator by additionally enforcing the similarity between the generated and real distributions. We implement a one-sample test on the generated samples and employ the resulting test statistic to penalize deviations from the real distribution. Our method encompasses a practical strategy to estimate distributions, compute the test statistic via a differentiable function, and seamlessly incorporate test outcomes into the training objective. Crucially, our approach preserves the convergence and theoretical integrity of GANs, as the introduced constraint represents a requisite condition for optimizing the generator training objective. Notably, our method circumvents reliance on regularization or network modules, enhancing compatibility and facilitating its practical application. Empirical evaluations on diverse public datasets validate the efficacy of our proposed approach.
