Asymptotic Statistical Analysis of $f$-divergence GAN

no code implementations14 Sep 2022 Xinwei Shen, Kani Chen, Tong Zhang

We show that for parametric generative models that are correctly specified, all $f$-divergence GANs with the same discriminator classes are asymptotically equivalent under suitable regularity conditions.

Bidirectional Generative Modeling Using Adversarial Gradient Estimation

2 code implementations21 Feb 2020 Xinwei Shen, Tong Zhang, Kani Chen

This paper considers the general $f$-divergence formulation of bidirectional generative modeling, which includes VAE and BiGAN as special cases.

A General Pairwise Comparison Model for Extremely Sparse Networks

no code implementations20 Feb 2020 Ruijian Han, Yiming Xu, Kani Chen

Under this setup, we show that the maximum likelihood estimator for the latent score vector of the subjects is uniformly consistent under a near-minimal condition on network sparsity.
