Permutation entropy and its main biomedical and econophysics applications: a review

M Zanin, L Zunino, OA Rosso, D Papo - Entropy, 2012 - mdpi.com
Entropy is a powerful tool for the analysis of time series, as it allows describing the
probability distributions of the possible state of a system, and therefore the information …

Practical considerations of permutation entropy: A tutorial review

M Riedl, A Müller, N Wessel - The European Physical Journal Special …, 2013 - Springer
More than ten years ago Bandt and Pompe introduced a new measure to quantify
complexity in measured time series. During these ten years, this measure has been modified …

Dispersion entropy: A measure for time-series analysis

M Rostaghi, H Azami - IEEE Signal Processing Letters, 2016 - ieeexplore.ieee.org
One of the most powerful tools to assess the dynamical characteristics of time series is
entropy. Sample entropy (SE), though powerful, is not fast enough, especially for long …

Distinguishing noise from chaos

OA Rosso, HA Larrondo, MT Martin, A Plastino… - Physical review …, 2007 - APS
Chaotic systems share with stochastic processes several properties that make them almost
undistinguishable. In this communication we introduce a representation space, to be called …

Amplitude-and fluctuation-based dispersion entropy

H Azami, J Escudero - Entropy, 2018 - mdpi.com
Dispersion entropy (DispEn) is a recently introduced entropy metric to quantify the
uncertainty of time series. It is fast and, so far, it has demonstrated very good performance in …

Improved multiscale permutation entropy for biomedical signal analysis: Interpretation and application to electroencephalogram recordings

H Azami, J Escudero - Biomedical Signal Processing and Control, 2016 - Elsevier
Permutation entropy (PE) is a well-known and fast method extensively used in many
physiological signal processing applications to measure the irregularity of time series …

Forbidden patterns, permutation entropy and stock market inefficiency

L Zunino, M Zanin, BM Tabak, DG Pérez… - Physica A: Statistical …, 2009 - Elsevier
In this paper we introduce two new quantifiers for the stock market inefficiency: the number
of forbidden patterns and the normalized permutation entropy. They are model-independent …

Automated emotion identification using Fourier–Bessel domain-based entropies

A Nalwaya, K Das, RB Pachori - Entropy, 2022 - mdpi.com
Human dependence on computers is increasing day by day; thus, human interaction with
computers must be more dynamic and contextual rather than static or generalized. The …

Amplitude-aware permutation entropy: Illustration in spike detection and signal segmentation

H Azami, J Escudero - Computer methods and programs in biomedicine, 2016 - Elsevier
Background and objective Signal segmentation and spike detection are two important
biomedical signal processing applications. Often, non-stationary signals must be segmented …

Complexity-entropy causality plane: A useful approach to quantify the stock market inefficiency

L Zunino, M Zanin, BM Tabak, DG Pérez… - Physica A: Statistical …, 2010 - Elsevier
The complexity-entropy causality plane has been recently introduced as a powerful tool for
discriminating Gaussian from non-Gaussian process and different degrees of correlations …
