Abstract: General multi-dimensional Bayesian network classifier (GMBNC) is one kind of Bayesian network (BN) tailored for the application of multi-dimensional classification,hence it contains only features necessary for the prediction.To avoid global search,a novel algorithm called DOS-GMBNC was proposed.It inherits the framework of existing IPC-GMBNC,conducts a dynamic order of search by making use of the underlying topology information.Experimental stu-dies indicate the effectiveness and efficiency of DOS-GMBNC.It outputs networks with equal quality as PC and iPC-GMBNC algorithms,and it brings considerable reduction of computation complexity,e.g.about 89% and 45% less than PC and IPC-GMBNC respectively on a 100-node network problem.
