WebPC 算法. 好的现在讲主题了,用 PC 算法 来学习出贝叶斯网络的结构。如上文所述,PC 算法会先确定节点间的依赖关系(但不确定方向),即先生成一个无向图,然后再确定依赖方向,把无向图扩展为完全部分有向无环图(Completed Partially Directed Acyclic Graph,CPDAG)。 WebGreedy Equivalent Search (GES) is an effective algorithm for Bayesian network problem, which searches in the space of graph equivalence classes. However, original GES may easily fall into local optimization trap because of empty initial structure. In this paper, An improved GES method is prosposed. It firstly makes a draft of the real network, based on … coligny partners
