摘要: 基于均匀概率空间的无穷乘积,在n值Lukasiewicz逻辑系统中引入命题的α-真度理论,给出了一般真度推理规则;利用命题的α-真度定义了命题间的α-相似度, 进而导出命题集上的一种伪距离,使得在n值命题逻辑系统中展开近似推理成为可能.
关键词: α-真度, 真度, 相似度, 伪距离, 近似推理
Abstract: By means of the infinite product of evenly distributed probability space, this paper introduces the theory of α-truth degrees in n-valued Lukasiewicz logical system, also, general reference rules with truth degrees are obtained. Moreover, a pseudo-metric on the set of propositions is defined by means of the concept of truth degrees of propositions and this make it possible to develop approximate reasoning in n-valued proposition logic.
Key words: α-Truth degree, Truth degree, Similarity degree, Pseudo-metric, Approximate reasoning
