Algorithm for exact recovery of Bayesian network for classification
摘要
Abstract
General Bayesian network classifier (GBNC)was the effective local section of the Bayesian network (BN)facing classification problem.Conventionally,it had to learn the global BN first,and existing structure learning algorithm imposed re-striction on possible problem scale.The paper developed an algorithm called IPC-GBNC for the exact recovery of GBNC with only local search.It conducted a breadth-first search with depth no more than 2 given the class node as the center.It proved its soundness,and experiments on synthetic and UCI real-world datasets demonstrate the merits of IPC-GBNC over classical PC al-gorithm which conducted global search:a)it produces same as or even higher quality of structure than PC,b)it saves considera-ble computation over PC,and c)effective dimension reduction is realized.As compared with state-of-the-art classifiers,GBNC not only performs as well on prediction,but inherits merits from being graphical model,like compact representation and power-ful inference ability.关键词
