摘要: Vague集的模糊熵应体现数据的未知性和自身的不确定性。分析了现有模糊熵的一些缺陷,并应用基于未知性和自身的不确定性的新模糊熵的公理化定义,构造了三个新模糊熵计算公式,分析了新模糊熵公式的合理性。

Abstract: The fuzzy entropy of vague sets should be calculated taking into the unknown and uncertainty.The deficiencies of existing fuzzy entropy of vague sets are analyzed in this paper.By use of an axiom definition of the fuzzy entropy of vague sets that according with the above two properties,three kinds of formulas of the fuzzy entropy of vague sets are also presented.It is proved that these formulas of the fuzzy entropy of vague sets are much more rational by analyzing.
