Subthreshold signal encoding in coupled FitzHugh-Nagumo neurons [article]

Maria Masoliver, Cristina Masoller
2017 arXiv   pre-print
By simulating the FitzHugh-Nagumo stochastic model and then using a symbolic method to analyze the firing activity of the neuron, preferred and infrequent spike patterns (defined by the relative timing  ...  We also show that the probabilities of the symbolic patterns achieve maximum or minimum values when the period of the external signal is close to (or is half of) the mean firing period of the neuron.  ...  Parlitz U, Berg S, Luther S, Schirdewan A, Kurths J, Wessel N (2012) Classifying cardiac biosignals using ordinal pattern statistics and symbolic dynamics.

Using Permutations for Hierarchical Clustering of Time Series

Jose Cánovas, Antonio Guillamón, María Ruiz-Abellón
2019 Entropy  
The effect of the embedding dimension and the linkage method are also analyzed. Finally, several real data series are properly clustered using the proposed method.  ...  We apply these distances to both simulated theoretical and real data series.  ...  On the other hand, the discriminative power of ordinal pattern statistics and symbolic dynamics to classify cardiac biosignals has been evaluated in [17] , whereas [18] uses ordinal patterns to detect  ...
