【摘要】 在不完备信息系统和模糊决策信息系统的基础上,提出一种基于相容关系的不完备模糊决策信息系统的粗糙集模型,并重新定义了不完备模糊决策信息系统上任意子集的上下近似,给出了基于属性依赖度的启发式知识约简算法,通过实例验证了算法的可行性。更多还原

【Abstract】 This paper proposes the concept of incomplete and fuzzy decision information system based on the compatibility relations,and redefined the upper and lower approximation of an arbitrary subset in the incomplete information system and fuzzy decision information system,given an heuristic attribute reduction algorithm about the dependence of knowledge,which is verified by an example.更多还原
