Refined Composite Multivariate Multiscale Fuzzy Dispersion Entropy: Theoretical Analysis and Applications

Chaos, Solitons and Fractals
Multivariate multiscale sample entropy (mvMSE) is a popular method to quantify the irregularity of multi-channel time series. However, mvMSE generates either undefined or unreliable results for short-length signals and has a high computational cost. To address these issues, multivariate multiscale dispersion entropy (mvMDE) was recently developed, but ...

Dispersion Entropy-based Fuzzy Classification for Motor Imagery Electroencephalogram

, 2022
Fuzzy logic-based systems are a widely used method for both classification and control. Electroencephalography sign is frequently used in some studies such as Brain-Computer Interfaces. In this study, the popular and up-to-date Dispersion Entropy method is used to determine the values of fuzzy membership functions. The dynamic properties of time series
