This paper introduces a modified fuzzy decision tree model. Firstly, the data are fuzzed by the use of optimal division point with optimal division entropy. Secondly, uncertainty theory of fuzzy math is introduced and a tree is built according to uncertainty of classification and creation rule. Finally, each unit can be detected about whether or not it is a fraud according to rule match method.

介绍了一种改进的模糊决策二叉树模型，即采用最优分割熵方法确定最优割点来对数据模糊化，引入模糊数学中的不确定性理论，依据分类的不确定性建造树，生成规则，在此基础上利用规则匹配的方法检测任意的样本数据是否为欺诈数据。
