Phase Transitions for Support Recovery from Gaussian Linear Measurements
Lekshmi Ramesh, Chandra R. Murthy, Himanshu Tyagi
We study the problem of recovering the common -sized support of a set of samples of dimension , using noisy linear measurements per sample. Most prior work has focuse…

Sample-Measurement Tradeoff in Support Recovery under a Subgaussian Prior
Lekshmi Ramesh, Chandra R Murthy, Himanshu Tyagi
Data samples from with a common support of size are accessed through random linear projections (measurements) per sample. It is well-known that roughly …
