Sparse Signal Inversion with Impulsive Noise by Dual Spectral Projected Gradient Method
We consider sparse signal inversion with impulsive noise. There are three major ingredients. The first is regularizing properties; we discuss convergence rate of regularized solutions. The second is devoted to the numerical solutions. It is challenging due to the fact that both fidelity and regulari...
