Improved Algorithm for Decision Tree Based on Positive Region
一种改进的基于正区域的决策树算法

In this paper,the relationship of selected attribute standards between based on positive region,based on rough bound and based on attribute dependency is firstly analyzed.At the same time,it is proved that the three kinds of selected attribute standards are equivalent to each other.And then advantages and disadvantages of algorithm for constructing decision tree based on positive region are analyzed.Meanwhile,aiming at these disadvantages,a new se- lected attribute standard based on adjoint positive region ...
