双论域的一般多粒度粗糙集
General multi-granulation rough set over two universes
摘要
Abstract
The research of multi-granulation rough set is an important theory in recent years. In this paper, the multi-granu-lation and two universes are combined. Firstly, the support functions in different universes are defined;secondly, the general multi-granulation rough set approximation operators in different universes are constructed by support functions, and the properties of the approximation operators are studied. What's more, the roughness and precision are discussed. Finally, an example about course selection in college students illustrates the feasibility and efficiency of this model.关键词
