Webbconstruct a variant of the ADMM algorithm that simplifies the inverse problem, or use a proximal gradient approach that avoids it altogether. In [13][12], the authors use the ADMM algorithm for sparse coding. They observe that if the dictionary is a tight frame, that is, DDT = I, then the inverse can be simplified WebbHiroki Iimori received his B.Eng. degree and M.Eng. degree (Hons.) in Electrical and Electronic Engineering from Ritsumeikan University, Kyoto, Japan, in 2024 and 2024, respectively, and his Ph.D. degree (Summa Cum Laude) in Electrical Engineering from Jacobs University Bremen, Germany in 2024.
