Covering Rough Set Model Based on Multi-granulations

  • Conference paper
Rough Sets, Fuzzy Sets, Data Mining and Granular Computing (RSFDGrC 2011)

Part of the book series: Lecture Notes in Computer Science ((LNAI,volume 6743))

Abstract

The paper extends the covering rough set model based on single granulation to the covering rough set model based on multi- granulations, which is named CMGRS. The lower and upper approximations of a set in a covering approximation space are defined based on multi-granulations, and some basic properties are investigated.
