Constructing Method for Decision Trees Based on Rough Sets

WEI Ping-ping(Department of Mathematics and Computer Science,Guizhou Institute of Education, Guiyang 550003,China)  
During constructing a decision,how to select classified attributes influences the effect of classification.This paper introduces a new way for selecting attributes,called Sets Classify Roughness,which is based on Rough sets theory and the characteristic of the decision tree and can elevate the level of leaf node to a degree when the total number does not change.
