题目：Recovery of Signals with Structures from Incomplete Information

内容简介：In this talk, we consider the recovery conditions for the exact recovery of signals with structures in the noiseless setting and stable recovery in the noisy case from incomplete information. The structure includes sparsity, block structure or the context when some prior information on the support of the signals is available. Moreover, we consider the optimality or sharpness of these sufficient conditions. Key Words: Compressed sensing, RIP, convex program, greedy algorithm
