New explicit thresholding/shrinkage formulas for one class of regularization problems with overlapping group sparsity and their applications
Gang Liu, Ting-Zhu Huang, Xiao-Guang Lv +1
The least-square regression problems or inverse problems have been widely studied in many fields such as compressive sensing, signal processing, and image processing. To solve this…
