1)  knowledge entropy
知识熵
1.
Some created concepts such as condition entropy,joint entropy,knowledge entropy,decision entropy,knowledge cough entropy and cough-sets cough entropy enrich rough sets theory,however,the denotations are not clear,and even lacking of the necessary explanations and proofs.
随着对粗糙集理论研究的的深入,基于信息论的信息熵陆续被引入到粗糙集研究中,陆续产生了一些如条件熵、联合熵、知识熵、决策熵、知识粗糙熵、粗集粗糙熵等新的概念,尽管丰富了粗糙集理论和应用,但使用中存在语义不统一的地方,甚至缺乏必要的说明和证明。
2)  knowledge rough entropy
知识粗糙熵
3)  the entropy of knowledge-information
知识信息熵
1.
Based on Shannon s Theory of information,The author analyzed the correlative characteristic of knowledge and knowledge-information,and brought forward an approximate method for estimating the entropy of knowledge-information which could be expressed in proposition.
基于申农(Shannon)的狭义信息论思想,分析了知识和知识信息的相关特征,提出一种关于以命题形式表征知识信息熵的近似计量估算方法。
4)  Knowledge transfer entropy
知识转移熵
5)  knowledge management entropy
知识管理熵
1.
By quantizing the knowledge management entropy and dissipative structure negentropy,basic standard to judge the system is established.
通过对合作创新系统的知识管理熵与耗散结构系统负熵的量化,导出对合作创新系统状态判别的基本标准。
6)  perceptual entropy
感知熵
1.
On the basis of the psycho-acoustic model,the perceptual entropy for wideband monophonic audio signal is in the range of 3~5bps,which means that for an uncompressed audio signal,a significant amount of additional information can be inserted into signal without causing a perceptual distortion.
在心理声学模型基础上,对于宽带单声道音频信号感知熵取值于3~5bps的范围,这就意味着对于未经压缩的音频信号,大量的水印信号可以添加到原始音频信号当中而不会产生失真。
补充资料:标准熵
分子式:
CAS号:

性质:根据热力学第三定律的普朗克表述(即0K时,纯物质的完整晶体的熵等于零)规定的物质的熵的绝对值,有时也称为规定熵(conventional entropy)。物理化学手册中给出的是纯物质在标准状态和298.15K的摩尔规定熵,也称为标准熵,符号Sm,298.15,单位J/(K·mol)。在确定熵值时需要用量热方法测量热容Cp与温度的关系以及各种相变热,因此规定熵也称量热熵(calorimetric entropy)。
