[Special Effects] Message-Passing-Algorithms DL : 0: 一本将基于AP传播算法的半监督聚类的算方法书.对于聚类研究的很有帮助-The Uncapacitated Facility Location Prob- lem (UFLP) is one of the most widely stud- ied discrete location problems, whose appli- cations arise in a variety of settings. We tackle the UFLP using probabilistic infer- ence in a graphical model- an approach that has received little attention in the past. We show that the ﬁ xed points of max-product linear programming (MPLP), a convexiﬁ ed version of the max-product algorithm, can be used to construct a solution with a 3- approximation guarantee for metric UFLP instances. In addition, we characterize some scenarios under which the MPLP solution is guaranteed to be globally optimal. We eval- uate the performance of both max-sum and MPLP empirically on metric and non-metric problems, demonstrating the advantages of the 3-approximation construction and algo- rithm applicability to non-metric instances.
