Granular Computing and its Applications in Data Mining
粒度计算及其在数据挖掘中的应用

Granular computing (GrC) involves the theories,methodologies,techniques,and tools that make use of granules in the process of problem solving.This paper introduces the basic ideas and basic issues of GrC,as well as three main GrC models:fuzzy set,rough set and quotient space.After that,the applications of GrC in data mining are discussed.
