Bregman Proximal Linearized ADMM for Minimizing Separable Sums Coupled by a Difference of Functions
Tan Nhat Pham, Minh N. Dao, Andrew Eberhard +1
In this paper, we develop a splitting algorithm incorporating Bregman distances to solve a broad class of linearly constrained composite optimization problems, whose objective func…
