Improved Stochastic Gradient Matching Pursuit Algorithm Based on the Soft-Thresholds Selection
The preliminary atom set exits redundant atoms in the stochastic gradient matching pursuit algorithm, which affects the accuracy of the signal reconstruction and increases the computational complexity. To overcome the problem, an improved method is proposed. Firstly, a limited soft-threshold selecti...
