Revisiting the decay of missing ordinal patterns in long-term correlated time series
(Elsevier Science, 2019-11-15)
We revisit the decay of missing ordinal patterns in long-term correlated time series. More precisely, a stretched exponential model is proposed to describe more appropriately how the number of missing ordinal patterns ...
Fisher information measure and causal probability distribution of Bandt and Pompe: application to the chaotic dynamical systems analysisMedida de Información de Fisher y distribución causal de probabilidad de Bandt y Pompe: Aplicaciones al análisis de sistemas dinámicos caóticos
(2013)
The potentiality of a special approximation of the Theory of Information is studied with the purpose of unveil dynamical structures of nonlinear dynamics. The focus here lies on information quantifiers: Shannon entropy, ...
Unraveling the decay of the number of unobserved ordinal patterns in noisy chaotic dynamics
(American Physical Society, 2019-10)
In this paper, we introduce a model to describe the decay of the number of unobserved ordinal patterns as a function of the time series length in noisy chaotic dynamics. More precisely, we show that a stretched exponential ...
Ambiguities in Bandt-Pompes methodology for local entropic quantifiers
(Elsevier Science, 2012)
Flujo de información en sistemas dinámicos extendidos
(2020)
En este trabajo se evalúan la información mutua y la transferencia de entropía como medidas de correlación entre diferentes variables de sistemas que simulan procesos en la atmósfera. La dinámica atmosférica puede ...
Classification and Verification of Handwritten Signatures with Time Causal Information Theory Quantifiers
(Public Library of Science, 2016-12)
We present a new approach for handwritten signature classification and verification based on descriptors stemming from time causal information theory. The proposal uses the Shannon entropy, the statistical complexity, and ...
Discriminating chaotic and stochastic dynamics through the permutation spectrum test
(American Institute Of Physics, 2014-09)
In this paper, we propose a new heuristic symbolic tool for unveiling chaotic and stochastic dynamics: the permutation spectrum test. Several numerical examples allow us to confirm the usefulness of the introduced methodology. ...
Complejidad de patrones dinámicos en oscilaciones estocásticas corticales
(Bogotá - Ciencias - Maestría en Ciencias - EstadísticaDepartamento de EstadísticaUniversidad Nacional de Colombia - Sede Bogotá, 2020-01-20)
This work presents the results of the study of two dynamical parameters from cortical stochastic oscillations in time series of a 40-subjects group of healthy adults in resting state (RS): normalized permutation entropy ...
