Optimal Shrinkage of Singular Values Under Random Data Contamination
Danny Barash, Matan Gavish
A low rank matrix X has been contaminated by uniformly distributed noise, missing values, outliers and corrupt entries. Reconstruction of X from the singular values and singular ve…
ReFACTor: Practical Low-Rank Matrix Estimation Under Column-Sparsity
Matan Gavish, Regev Schweiger, Elior Rahmani +1
Various problems in data analysis and statistical genetics call for recovery of a column-sparse, low-rank matrix from noisy observations. We propose ReFACTor, a simple variation of…
Near-optimal matrix recovery from random linear measurements
Elad Romanov, Matan Gavish
In matrix recovery from random linear measurements, one is interested in recovering an unknown -by- matrix from measurements where each …
Random Subsets of Structured Deterministic Frames have MANOVA Spectra
Marina Haikin, Ram Zamir, Matan Gavish
We draw a random subset of rows from a frame with rows (vectors) and columns (dimensions), where and are proportional to . For a variety of important determi…
