DigGAN: Discriminator gradIent Gap Regularization for GAN Training with Limited Data

1 code implementation27 Nov 2022 Tiantian Fang, Ruoyu Sun, Alex Schwing

In contrast, we propose a Discriminator gradIent Gap regularized GAN (DigGAN) formulation which can be added to any existing GAN.

Precondition Layer and Its Use for GANs

no code implementations1 Jan 2021 Tiantian Fang, Alex Schwing, Ruoyu Sun

We use this PC-layer in two ways: 1) fixed preconditioning (FPC) adds a fixed PC-layer to all layers, and 2) adaptive preconditioning (APC) adaptively controls the strength of preconditioning.

Towards a Better Global Loss Landscape of GANs

1 code implementation NeurIPS 2020 Ruoyu Sun, Tiantian Fang, Alex Schwing

We also perform experiments to support our theory that RpGAN has a better landscape than separable-GAN.

Co-Generation with GANs using AIS based HMC

1 code implementation NeurIPS 2019 Tiantian Fang, Alexander G. Schwing

Inferring the most likely configuration for a subset of variables of a joint distribution given the remaining ones - which we refer to as co-generation - is an important challenge that is computationally demanding for all but the simplest settings.

CP-GAN: Towards a Better Global Landscape of GANs

no code implementations25 Sep 2019 Ruoyu Sun, Tiantian Fang, Alex Schwing

In this work, we perform a global analysis of GANs from two perspectives: the global landscape of the outer-optimization problem and the global behavior of the gradient descent dynamics.
