A noise-robust Multivariate Multiscale Permutation Entropy for two-phase flow characterisation
John Stewart Fabila-Carrasco, Chao Tan, Javier Escudero
Using a graph-based approach, we propose a multiscale permutation entropy to explore the complexity of multivariate time series over multiple time scales. This multivariate multisc…
A geometric construction of isospectral magnetic graphs
John Stewart Fabila-Carrasco, Fernando Lledó, Olaf Post
We present a geometrical construction of families of finite isospectral graphs labelled by different partitions of a natural number of given length (the number of summands)…
Isospectral graphs via spectral bracketing
Fernando Lledó, John S. Fabila-Carrasco, Olaf Post
In this article, we develop a perturbative technique to construct families of non-isomorphic discrete graphs which are isospectral for the standard (also called normalised) Laplaci…
Multivariate permutation entropy, a Cartesian graph product approach
John Stewart Fabila-Carrasco, Chao Tan, Javier Escudero
Entropy metrics are nonlinear measures to quantify the complexity of time series. Among them, permutation entropy is a common metric due to its robustness and fast computation. Mul…
