Permutation complexity of interacting dynamical systems
Roberto Monetti, José María Amigó, Thomas Aschenbrenner +1
The coupling complexity index is an information measure introduced within the framework of ordinal symbolic dynamics. This index is used to characterize the complexity of the relat…
Information directionality in coupled time series using transcripts
Roberto Monetti, Wolfram Bunk, Thomas Aschenbrenner +2
In ordinal symbolic dynamics, transcripts describe the algebraic relationship between ordinal patterns. Using the concept of transcript, we exploit the mathematical structure of th…
Spatio-Temporal Structuring of Brain Activity - Description of Interictal EEG in Paediatric Frontal Lobe Epilepsy
W. Bunk, T. Aschenbrenner, G. Kluger +1
A method for the quantitative assessment of spatio-temporal structuring of brain activity is presented. This approach is employed in a longitudinal case study of a child with front…
Characterizing Synchronization in Time Series using Information Measures Extracted from Symbolic Representations
Roberto Monetti, Wolfram Bunk, Ferdinand Jamitzky
We present a methodology to characterize synchronization in time series based on symbolic representations. A symbol is linked to a sequence of numbers through the rank-order of its…
Detecting non-linearities in data sets. Characterization of Fourier phase maps using the Weighted Scaling Indices
Roberto A. Monetti, Wolfram Bunk, Ferdinand Jamitzky +2
We present a methodology for detecting non-linearities in data sets based on the characterization of the structural features of the Fourier phase maps. A Fourier phase map is a 2D…
Analysing Large Scale Structure: I. Weighted Scaling Indices and Constrained Randomisation
C. Raeth, W. Bunk, M. Huber +3
The method of constrained randomisation is applied to three-dimensional simulated galaxy distributions. With this technique we generate for a given data set surrogate data sets whi…
