摘要
利用模糊逻辑中的R-型蕴涵算子定义随机模糊信息系统对象集上的模糊等价关系,进而实现对随机模糊信息系统知识的近似表示。讨论随机模糊下近似、上近似集的模糊概率与模糊信任测度、模糊似然测度之间的关系。给出基于模糊信任测度和模糊似然测度的随机模糊信息系统知识约简的方法。
In this paper, the fuzzy equivalent relation in the object set of random fuzzy information system are defined by virtue of R-imply operators in fuzzy logic. The approximate representation of knowledge in the random fuzzy information system is obtained. The relationship between fuzzy probability defined by lower approximation and upper approximation of random fuzzy sets and fuzzy belief measures, fuzzy plausibility measures is discussed. The knowledge reduction method based on fuzzy belief measures and fuzzy plausibility measures are introduced.
