We ( proved) that the membership functions of fuzzy union-preserving mapping and fuzzy meet-preserving ( mapping) may be expressed by the composite operation of fuzzy relation and operator. 本文证明了模糊保并、保交映射的隶属函数可以表示为模糊关系与算子的合成。
Fuzzy production rule reasoning based on similarity is a kind of method generally used in classification. It depends on the selection of related functions, such as membership, similarity and match operator. 基于相似性的模糊产生规则推理是广泛应用于分类问题的一种推理方法,推理过程依赖于隶属函数、相似度和推理算子等函数的选择,不同的函数可能会导致不同的推理结果。
Fuzzy entropy is introduced to evaluate the enhancement effects and the characteristic of the sine membership function and generalized fuzzy enhancement operator is analyzed. 引入了模糊熵的方法来评价图像的增强效果,并对提出的正弦隶属度函数及广义模糊增强算子的特性进行了分析。
We discussed the dynamics of two cases that the model of multicast group membership changes and the model of network topology changes. The population update operator and individual repair operator are introduced into the algorithm to compensate and repair the multicast tree after the dynamic changes. 讨论了网络中组播组成员变化和网络拓扑结构变化两种情况的动态变化,本算法中引入种群更新算子和个体修复等算子对动态变化对组播树产生的影响进行修复和补偿。
