Multi-Granularity Variable Precision Soft Rough Set

View through CrossRef
This paper briefly introduces the basic concepts of rough sets, and then introduces some current research status of rough sets. Based on this, a multi-granularity variable precision soft rough set (MGVPSRS) is proposed and some related properties are given. Then a new reduction algorithm is proposed by using the multi-granularity variable precision soft rough set model and applied to the weather classification problem.
