Ordinal symbolic analysis opens an interesting and powerful perspective on time-series
analysis. Here, we review this relatively new approach and highlight its relation to symbolic …

… The paper was written by all three authors, where VA Unakafova was mainly responsible for
… AM Unakafov and VA Unakafova. All authors have read and approved the final manuscript. …

Permutation entropy, introduced by Bandt and Pompe, is a conceptually simple and well-interpretable
measure of time series complexity. In this paper, we propose efficient methods for …

Analysis of spike and local field potential (LFP) data is an essential part of neuroscientific
research. Today there exist many open-source toolboxes for spike and LFP data analysis …

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 time-…

In this paper we discuss the relationship between permutation entropy and Kolmogorov-Sinai
entropy in the one-dimensional case. For this, we consider partitions of the state space of a …

This thesis is devoted to the investigation of complexity measures for dynamical systems and
for time series. The central concepts throughout the thesis are the permutation entropy and …

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 …
