Tight Measurement Bounds for Exact Recovery of Structured Sparse Signals
Nikhil Rao, Benjamin Recht, Robert Nowak
Standard compressive sensing results state that to exactly recover an s sparse signal in R^p, one requires O(s. log(p)) measurements. While this bound is extremely useful in practi…

Convex Approaches to Model Wavelet Sparsity Patterns
Nikhil S Rao, Robert D. Nowak, Stephen J. Wright +1
Statistical dependencies among wavelet coefficients are commonly represented by graphical models such as hidden Markov trees(HMTs). However, in linear inverse problems such as deco…
