Fast One-Pass Sparse Approximation of the Top Eigenvectors of Huge Approximately Low-Rank Matrices? Yes, !

Edem Boahen, Simone Brugiapaglia, Hung-Hsu Chou +2

Motivated by applications such as sparse PCA, in this paper we present provably-accurate one-pass algorithms for the sparse approximation of the top eigenvectors of extremely massi…

High-Dimensional Confidence Regions in Sparse MRI

Frederik Hoppe, Felix Krahmer, Claudio Mayrink Verdun +2

One of the most promising solutions for uncertainty quantification in high-dimensional statistics is the debiased LASSO that relies on unconstrained -minimization. The init…

Proof methods for robust low-rank matrix recovery

Tim Fuchs, David Gross, Peter Jung +3

Low-rank matrix recovery problems arise naturally as mathematical formulations of various inverse problems, such as matrix completion, blind deconvolution, and phase retrieval. Ove…
