摘要
Abstract
When classical rou tribute decision table, discretizi set theory is used to deal with the problems of continuous valued at- ng continuous valued attributes will result in loss of information. Meanwhile the classical rough set model can not deal with imprecise classification. To solve the above problems, variable precision rough set model based on the gray absolute correlation degree has been established and some properties of the model are studied ; and then a reduction algorithm based on the significant degree is designed; finally, an example is used to illustrate the process of the model foun- dation and reduction.关键词
