Optimal tuning-free convex relaxation for noisy matrix completion

Yuepeng Yang, Cong Ma

This paper is concerned with noisy matrix completion--the problem of recovering a low-rank matrix from partial and noisy entries. Under uniform sampling and incoherence assumptions…

Optimally tackling covariate shift in RKHS-based nonparametric regression

Cong Ma, Reese Pathak, Martin J. Wainwright

We study the covariate shift problem in the context of nonparametric regression over a reproducing kernel Hilbert space (RKHS). We focus on two natural families of covariate shift…
