A Strategy of Constructing Heterogeneous Cost-sensitive Decision Tree

摘要：

　　Usually,the algorithm of constructing cost-sensitive decision tree assume that all types of cost can be converted into a unified units of the same price,apparently how to construct an cost conversion function is an challenge.In this paper,a strategy of constructing heterogeneous cost-sensitive decision tree is designed and the different cost are take into account together in split attribute selection.Whats more,an attribute selection model based on heterogeneous cost-sensitive is constructed and the pruning strategy based on cost-sencitive is designed.The experimental results show that the proposed method is correct and more efficient than the present other methods
