Robust Density Estimation under Besov IPM Losses

no code implementations NeurIPS 2020 Ananya Uppal, Shashank Singh, Barnabas Poczos

We study minimax convergence rates of nonparametric density estimation in the Huber contamination model, in which a proportion of the data comes from an unknown outlier distribution.

Nonparametric Density Estimation & Convergence Rates for GANs under Besov IPM Losses

no code implementations NeurIPS 2019 Ananya Uppal, Shashank Singh, Barnabás Póczos

Thus, we show how our results imply bounds on the statistical error of a GAN, showing, for example, that GANs can strictly outperform the best linear estimator.

Nonparametric Density Estimation under Adversarial Losses

no code implementations NeurIPS 2018 Shashank Singh, Ananya Uppal, Boyue Li, Chun-Liang Li, Manzil Zaheer, Barnabás Póczos

We study minimax convergence rates of nonparametric density estimation under a large class of loss functions called "adversarial losses", which, besides classical $\mathcal{L}^p$ losses, includes maximum mean discrepancy (MMD), Wasserstein distance, and total variation distance.
