Sparse Signal Recovery from Random Measurements

Man Ting Wong, Siu-Wing Cheng

Given the compressed sensing measurements of an unknown vector $z \in R^{n}$ using random matrices, we present a simple method to determine $z$ without solving any optimizat…

A Dynamic Working Set Method for Compressed Sensing

Siu-Wing Cheng, Man Ting Wong

We propose a dynamic working set method (DWS) for the problem $min_{x \in R^{n}} \frac{1}{2} ∥ Ax - b ∥^{2} + I^\cdot ∥ x ∥_{1}$ that arises from com…
