In view of basis on analyzing insufficient of the classifacation and regression trees(CART) algorithm

which requests the choosen attribute is continual and having order

and onlycan produce two children nodes

based on CART algorithm theory

this paper uses A-CART the algorithm

makes up the CART method insufficiency

namely the method which selects the discrete and disorder attribute to accomplish split point of decision tree

after splitting it may have many split node.It has designed a split function for the a...
