Attribute-Efficient PAC Learning of Low-Degree Polynomial Threshold Functions with Nasty Noise

no code implementations1 Jun 2023 Shiwei Zeng, Jie Shen

The concept class of low-degree polynomial threshold functions (PTFs) plays a fundamental role in machine learning.

List-Decodable Sparse Mean Estimation

no code implementations28 May 2022 Shiwei Zeng, Jie Shen

Robust mean estimation is one of the most important problems in statistics: given a set of samples in $\mathbb{R}^d$ where an $\alpha$ fraction are drawn from some distribution $D$ and the rest are adversarially corrupted, we aim to estimate the mean of $D$.

Efficient PAC Learning from the Crowd with Pairwise Comparisons

no code implementations2 Nov 2020 Shiwei Zeng, Jie Shen

We study crowdsourced PAC learning of threshold functions, where the labels are gathered from a pool of annotators some of whom may behave adversarially.
