题目:Coordinate descent algorithms
摘要:
Coordinate descent (CD) algorithms solve an optimization problem by solving a sequence of simpler optimization that updates one coordinate (or block of coordinates) each time. It is useful in solving large-scale optimization problems with smooth or non-smooth and convex or non-convex objective functions. These methods are generally applicable to a variety of problems involving large or high-dimensional data sets since they naturally break down complicated optimization problems into simpler subproblems which are easily parallelized or distributed. In addition, CD is applicable to non-convex problems.
