Confidence Sets for the Source of a Diffusion in Regular Trees

Justin Khim, Po-Ling Loh

We study the problem of identifying the source of a diffusion spreading over a regular tree. When the degree of each node is at least three, we show that it is possible to construc…

High-dimensional robust precision matrix estimation: Cellwise corruption under -contamination

Po-Ling Loh, Xin Lu Tan

We analyze the statistical consistency of robust estimators for precision matrices in high dimensions. We focus on a contamination mechanism acting cellwise on the data matrix. The…

Statistical consistency and asymptotic normality for high-dimensional robust M-estimators

Po-Ling Loh

We study theoretical properties of regularized robust M-estimators, applicable when data are drawn from a sparse high-dimensional linear model and contaminated by heavy-tailed dist…
