摘要:
We live in the age of big data and dataof huge size is becoming ubiquitous. With thiscomesthe need to solve optimization problems of unprecedented size. Classicaloptimization algorithms are not designed to scale to instances of this size. Inthis talk, I introduce two typical decomposition methods —— BCDand ADMM, for solving large scale optimization problems and present somenovel theoretical results on these two methods. Some interestingapplications, including matrix completion, pricing discrimination forinformation goods and sparse portfolio selection are also discussed.
