On entropy, entropy-like quantities, and applications
José M. Amigó, Karsten Keller, Valentina Unakafova
This is a review on entropy in various fields of mathematics and science. Its scope is to convey a unified vision of the classical as well as some newer entropy notions to a broad…
An approach to comparing Kolmogorov-Sinai and permutation entropy
Valentina A. Unakafova, Anton M. Unakafov, Karsten Keller
In this paper we investigate a quantity called conditional entropy of ordinal patterns, akin to the permutation entropy. The conditional entropy of ordinal patterns describes the a…
On the Relation of KS Entropy and Permutation Entropy
Karsten Keller, Anton M. Unakafov, Valentina A. Unakafova
Since Bandt et al. have shown that the permutation entropy and the Kolmogorov-Sinai entropy coincide for piecewise monotone interval maps, the relationship of both entropies for ti…
