CART-Classification and Regression Trees algorithm is an important algorithm in Data Mining.In this paper,we based on the theory of CART algorithm,adopted the algorithm of solving the decision tree under the categorical variables,introduced the optimized splitting function,and then made use of the division of the universe of discourse in type variable to construct binary tree,extracted and screened the forecasting criterion.The purpose of this paper is to provide a scientific and reliable basis for the department decision.At last,the application example of the algorithm was provided with the data in teaching and administration of GuiZhou normal university in this paper.
