熵——度量随机变量不确定性的一种尺度
Entropy—A Measure of Uncertainty of Random Variable
【摘要】 本文首先论述了不确定性的概念,而后介绍熵及其性质。在此基础上,引进了微分熵。最后论述离散随机过程熵,并且得到了一些结论。
【Abstract】 At first, the concept of uncertainty has been discussed in this paper, then the entropy and its natures have been introduced.On this basis, differential entropy has been led into. At last, the entropy of discrete random processes has been discussed, and some conclusions have been obtained.
