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 $M$ -by- $N$ matrix $X_{0}$ from $n < M N$ measurements $y_{i} = T r (A_{i}^{T} X_{0})$ where each $A_{i}$ …

Random Subsets of Structured Deterministic Frames have MANOVA Spectra

Marina Haikin, Ram Zamir, Matan Gavish

We draw a random subset of $k$ rows from a frame with $n$ rows (vectors) and $m$ columns (dimensions), where $k$ and $m$ are proportional to $n$ . For a variety of important determi…
