SPRIGHT: A Fast and Robust Framework for Sparse Walsh-Hadamard Transform
Xiao Li, Joseph K. Bradley, Sameer Pawar +1
We consider the problem of computing the Walsh-Hadamard Transform (WHT) of some -length input vector in the presence of noise, where the -point Walsh spectrum is -sparse w…

Sub-linear Time Support Recovery for Compressed Sensing using Sparse-Graph Codes
Xiao Li, Dong Yin, Sameer Pawar +2
We study the support recovery problem for compressed sensing, where the goal is to reconstruct the a high-dimensional -sparse signal , from low-dimens…
