摘要

香农熵和柯尔莫哥洛夫复杂度是两个概念不同的信息指标,因为后者基于概率分布,而前者基于程序大小。然而,众所周知,所有递归概率分布都有一个完全取决于该分布的常数,即柯尔莫哥洛夫复杂度值等于其香农熵。我们研究了 Renyi 和 Havrda- Charvat 熵熵阶 α 之间是否存在类似的相关性,表明它仅与阶 1 的 Renyi 和 Havrda- Charvat 熵一致。我们将研究这种相似性的一个方面。具体来说,香农熵和柯尔莫哥洛夫复杂度的线性不等式是成立的。恰好,以下情况是正确的:(1) 所有线性不等式对香农熵成立,反之亦然;(2) 所有线性不等式对香农熵成立,反之亦然;(3) 所有线性不等式对线性空间有限子集的秩成立,反之亦然。

Uniform Estimates on Length of Programs and Computing Algorithmic Complexities for Quantitative Information Measures
Shannon entropy and Kolmogorov complexity are two conceptually distinct information metrics since the latter is based on probability distributions while the former is based on program size. All recursive probability distributions, however, are known to have an expected Up to a constant that solely depends on the distribution, the Kolmogorov complexity value is equal to its Shannon entropy. We investigate if a comparable correlation exists between Renyi and Havrda- Charvat Entropy entropies order α, indicating that it is consistent solely with Renyi and Havrda- Charvat entropies of order 1. Kolmogorov noted that the characteristics of Shannon entropy and algorithmic complexity are comparable. We examine a single facet of this resemblance. Specifically, linear inequalities that hold true for Shannon entropy and for Kolmogorov complexity. As it happens, the following are true: (1) all linear inequalities that hold true for Shannon entropy and vice versa for Kolmogorov complexity; (2) all linear inequalities that hold true for ranks of finite subsets of linear spaces for Shannon entropy; and (3) the reverse is untrue.
