A Sub-Quadratic Time Algorithm for Robust Sparse Mean Estimation
A Pensia - arxiv preprint arxiv:2403.04726, 2024 - arxiv.org
We study the algorithmic problem of sparse mean estimation in the presence of adversarial
outliers. Specifically, the algorithm observes a\emph {corrupted} set of samples from …
