Sample entropy for graph signals: An approach to nonlinear analysis of graph signals
Mei-San Maggie Lei, John Stewart Fabila Carrasco, Javier Escudero
We introduce a graph-signal generalisation of Sample Entropy, denoted SampEn, to quantify irregularity of graph signals on a continuous state space, complementing existing me…

Graph Permutation Entropy: Extensions to the Continuous Case, A step towards Ordinal Deep Learning, and More
Om Roy, Avalon Campbell-Cousins, John Stewart Fabila Carrasco +2
Nonlinear dynamics play an important role in the analysis of signals. A popular, readily interpretable nonlinear measure is Permutation Entropy. It has recently been extended for t…
