粒计算是一种基于问题概念空间划分的新的智能计算理论和方法,不相容决策表是粗集理论研究的一个重点,而粗集中的等价关系可以用来刻化等价粒.结合粒计算的处理方法给出了决策表信息系统的粒表示、粒运算规则和粒分解算法,同时结合粗集中的属性核计算方法,提出了决策表信息系统在粒表示下属性核的获取方法.
Granular computing is a new intelligent computing theory based on partition of problem concepts. Inconsistent decision table is an important aspect in rough set theory, and the equivalent relation in rough set theory is used to express equivalent granule. A decomposing model of granular computing in decision information system is developed. Furthermore, one also presents the method of getting core attributes based on granular mode in decision table.
