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…
