Multichannel Time-Frequency Complexity Measures for the Analysis of Age-Related Changes in Neuromagnetic Resting-State Activity
(Instituto de Ingeniería Eléctrica y Electrónica, 2019-01)
We propose new multichannel time-frequency complexity measures to evaluate differences on magnetoencephalograpy (MEG) recordings between healthy young and old subjects at rest at different spatial scales. After reviewing ...
Characterization of time series via Rényi complexity–entropy curves
(Elsevier Science, 2018-05)
One of the most useful tools for distinguishing between chaotic and stochastic time series is the so-called complexity-entropy causality plane. This diagram involves two complexity measures: the Shannon entropy and the ...
Complexity-entropy analysis of daily stream flow time series in the continental United States
(Springer Verlag Berlín, 2013-10)
Complexity–entropy causality plane (CECP) is a diagnostic diagram plotting normalized Shannon entropy HSHS versus Jensen–Shannon complexity CJSCJS that has been introduced in nonlinear dynamics analysis to classify ...
Time series analysis in earthquake complex networks
(American Institute of Physics Inc., 2018)
© 2018 Author(s). We introduce a new method of characterizing the seismic complex systems using a procedure of transformation from complex networks into time series. The undirected complex network is constructed from seismic ...
Complex network study of solar magnetograms
(MDPI, 2022)
In this paper, we study solar magnetic activity by means of a complex network approach. A complex network was built based on information on the space and time evolution of sunspots provided by image recognition algorithms ...
