Nonconvex Sparse Representation With Slowly Vanishing Gradient Regularizers
Sparse representation has been widely used over the past decade in computer vision and signal processing to model a wide range of natural phenomena. For computational convenience and robustness against noises, the optimization problem for sparse representation is often relaxed using convex or noncon...
