报告题目:Decomposition Methods for Large-Scale Optimization Problems and Their Applications
报告摘要:We live in the age of big data and data of huge size is becoming ubiquitous. With this comes the need to solve optimization problems of unprecedented size. Classical optimization algorithms are not designed to scale to instances of this size. In this talk, I introduce two typical decomposition methods —— BCD and ADMM, for solving large scale optimization problems and present some novel theoretical results on these two methods. Some interesting applications, including pricing discrimination for information goods and sparse portfolio selection are also discussed.
