Abstract

Abstract: A new method of knowledge acquisition based on intuitionistic fuzzy-rough sets is proposed.The model of rough sets under intuitionistic fuzzy equivalant relation is systemically investigated，the definition of positive field，the depend-degree and nodepend-degree and so forth are given.The basic processes of intuitionistic fuzzy-rough rules mining are particularly analyzed.Through a simple experiment，the application of the algorithm is testified.

Key words: intuitionistic fuzzy sets, intuitionistic fuzzy analogical relation, intuitionistic fuzzy-rough sets, positive field

摘要： 将粗糙集理论与直觉模糊集理论相结合，提出了一种基于直觉模糊粗糙集理论的知识获取方法。描述了直觉模糊相似关系下粗糙集的模型，并在此基础之上重新定义了正域、依赖度与非依赖度、确定性因子与非确定性因子等概念。详细分析了基于直觉模糊粗糙集的规则挖掘算法的基本步骤，最后通过实例验证了该算法的可行性。

关键词: 直觉模糊集, 直觉模糊相似关系, 直觉模糊粗糙集, 正域
