香农熵的再认识

Shannon's entropy revisited

Sergei Viznyuk

摘要:

我认为一个有限的样本大小的独立事件的样本的熵的影响。提出了满足香农公理的熵公式,并在样本容量为无穷大的情况下,简化为香农熵。我讨论了两个公式之间的差异的物理意义,包括一些实际的影响,如最大可实现的信道利用率,和最小可实现的通信协议开销,对于一个给定的消息大小。

英文摘要:

I consider the effect of a finite sample size on the entropy of a sample of independent events. I propose formula for entropy which satisfies Shannon's axioms, and which reduces to Shannon's entropy when sample size is infinite. I discuss the physical meaning of the difference between two formulas, including some practical implications, such as maximum achievable channel utilization, and minimum achievable communication protocol overhead, for a given message size.
