Looks interesting and well-written - I will need to take a closer look.
By Joseph Woodworth and .﻿
Abstract: The $\ell^0$ minimization of compressed sensing is often relaxed to $\ell^1$, which yields easy computation using the shrinkage mapping known as soft thresholding, and can be shown to recover the original solution under certain hypotheses. Recent work has derived a general class of ...
