不精确和欠定义或过定义信息的香农熵

Shannon entropy for imprecise and under-defined or over-defined information

Vasile Patrascu

摘要:

首先定义了概率分布的Shannon熵,然后将其应用扩展到完全信息系统的知识不确定性度量。本文提出将Shannon熵的应用推广到欠定或过定信息系统。为了能够使用香农熵,通过仿射变换对信息进行归一化。仿射变换的构造分为两个阶段:一个用于相似性,另一个用于平移。此外,这一办法还包括信息有一定程度不准确的情况。此外,本文还介绍了Shannon熵在一些特殊情况下的应用,如:三价和二价的模糊信息、双模糊信息、直觉模糊信息、不精确模糊信息、模糊划分等。

英文摘要:

Shannon entropy was defined for probability distributions and then its using was expanded to measure the uncertainty of knowledge for systems with complete information. In this article, it is proposed to extend the using of Shannon entropy to under-defined or over-defined information systems. To be able to use Shannon entropy, the information is normalized by an affine transformation. The construction of affine transformation is done in two stages: one for homothety and another for translation. Moreover, the case of information with a certain degree of imprecision was included in this approach. Besides, the article shows the using of Shannon entropy for some particular cases such as: neutrosophic information both in the trivalent and bivalent case, bifuzzy information, intuitionistic fuzzy information, imprecise fuzzy information, and fuzzy partitions.
