A Fast Algorithm for Adaptive Private Mean Estimation

no code implementations17 Jan 2023 John Duchi, Saminul Haque, Rohith Kuditipudi

We design an $(\varepsilon, \delta)$-differentially private algorithm to estimate the mean of a $d$-variate distribution, with unknown covariance $\Sigma$, that is adaptive to $\Sigma$.

Undersampling is a Minimax Optimal Robustness Intervention in Nonparametric Classification

1 code implementation26 May 2022 Niladri S. Chatterji, Saminul Haque, Tatsunori Hashimoto

While a broad range of techniques have been proposed to tackle distribution shift, the simple baseline of training on an $\textit{undersampled}$ balanced dataset often achieves close to state-of-the-art-accuracy across several popular benchmarks.

Is Importance Weighting Incompatible with Interpolating Classifiers?

1 code implementation ICLR 2022 Ke Alexander Wang, Niladri S. Chatterji, Saminul Haque, Tatsunori Hashimoto

As a remedy, we show that polynomially-tailed losses restore the effects of importance reweighting in correcting distribution shift in overparameterized models.
