Bregman Proximal Methods for Semidefinite Optimization
Lieven Vandenberghe (UCLA)
Abstract: Generalized proximal methods based on Bregman distances offer the possibility of matching the distance to the structure in the problem, with the goal of reducing the complexity per iteration. In semidefinite optimization, the use of a generalized distance can allow us to avoid expensive eigendecompositions, needed in standard proximal methods for Euclidean projections on the positive semidefinite cone. We discuss applications to sparse semidefinite optimization, and to other types of structure that are common in control and signal processing, such as Toeplitz structure.
