邻域系统粗糙集模型
Rough Set Model Based on Neighborhood System
摘要
Abstract
Considering the rough approximation with the different views, properties of the neighborhood system based rough set model are investigated. The neighborhood system based rough set is compared with the two different generalized rough sets,the variable precision rough set model and the multi-granulation rough set model. Two different neighborhood systems are constructed according to the classification error and the multi-granulations. It is proved that the variable precision rough set model and multi-granulation rough set model are special cases of the neighborhood system based rough set,and the neighborhood system based rough set is a more generalized rough approach.关键词
