Leveraging Contaminated Datasets to Learn Clean-Data Distribution with Purified Generative Adversarial Networks

2 code implementations3 Feb 2023 Bowen Tian, Qinliang Su, Jianxing Yu

When training on such datasets, existing GANs will learn a mixture distribution of desired and contaminated instances, rather than the desired distribution of desired data only (target distribution).

Global Convergence and Stability of Stochastic Gradient Descent

no code implementations4 Oct 2021 Vivak Patel, Shushu Zhang, Bowen Tian

Under a slightly more restrictive assumption on the joint behavior of the non-convexity and noise model that generalizes current assumptions in the literature, we show that the objective function cannot diverge, even if the iterates diverge.
