Accelerated Primal-Dual Proximal Block Coordinate Updating Methods for Constrained Convex Optimization

17 Feb 2017Yangyang XuShuzhong Zhang

Block Coordinate Update (BCU) methods enjoy low per-update computational complexity because every time only one or a few block variables would need to be updated among possibly a large number of blocks. They are also easily parallelized and thus have been particularly popular for solving problems involving large-scale dataset and/or variables... (read more)
