摘要
Abstract
It can qualitatively and quantitatively analyze the dependencies between attributes,and do probabilistic reasoning. In parameter learning of Bayesian network,it is usually assumed that all variables are discrete or continuous variables obeying Gauss-ian distribution,so it is necessary to do the discretization for those variables in reality which disobey the assumptions.In this paper, two different methods(equal width,ChiMerge)are used to discrete data set,then the results of discretization are used to construct the corresponding Bayesian network and do parameter learning in Netica.Finally,the resulting Bayesian network is used to do some simple forecast and analysis.关键词
