基于容差关系的不完备可变精度多粒度粗糙集
Incomplete variable precision multi-granulation rough sets based on tolerance relation
摘要
Abstract
To integrate the good points of variable precision rough set and multi-granulations rough set in the incomplete information system,this paper proposed the incomplete variable precision multi-granulation rough sets based on tolerance relation,and discussed the properties of variable precision multi-granulation optimistic approximation and variable precision multi-granulation pessimistic approximation.Through the analysis of variable precision multi-granulations rough set and the classical multigranulation rough set,it concluded that incomplete variable precision multi-granulation rough sets based on tolerance relation have a higher approximation.At last,results of the experiment show the effectiveness of the theory.关键词
