Global convergence rate of incremental aggregated gradient methods for nonsmooth problems
We analyze the proximal incremental aggregated gradient (PIAG) method for minimizing the sum of a large number of smooth component functions f(x) = Σ[subscript i=1]m f[subscript i](x) and a convex function r(x). Such composite optimization problems arise in a number of machine learning applications...
