A Modified Multivariable Complexity Measure Algorithm and Its Application for Identifying Mental Arithmetic Task

open access: yesEntropy, 2021
Properly measuring the complexity of time series is an important issue. The permutation entropy (PE) is a widely used as an effective complexity measurement algorithm, but it is not suitable for the complexity description of multi-dimensional data.

Multi-variable quaternionic spectral analysis [PDF]

open access: yesOpuscula Mathematica, 2021
In this paper, we consider finite dimensional vector spaces \(\mathbb{H}^n\) over the ring \(\mathbb{H}\) of all quaternions. In particular, we are interested in certain functions acting on \(\mathbb{H}^n\), and corresponding functional equations.
