Applying Improved Multiscale Fuzzy Entropy for Feature Extraction of MI-EEG [PDF]

open access: yesApplied Sciences (Switzerland), 2017
Electroencephalography (EEG) is considered the output of a brain and it is a bioelectrical signal with multiscale and nonlinear properties. Motor Imagery EEG (MI-EEG) not only has a close correlation with the human imagination and movement intention but ...

Refined multiscale fuzzy entropy based on standard deviation for biomedical signal analysis [PDF]

open access: yesMedical and Biological Engineering and Computing, 2017
Multiscale entropy (MSE) has been a prevalent algorithm to quantify the complexity of fluctuations in the local mean value of biomedical time series. Recent developments in the field have tried to improve the MSE by reducing its variability in large scale factors. On the other hand, there has been recent interest in using other statistical moments than

Multiscale Entropy Analysis of Short Signals: The Robustness of Fuzzy Entropy-Based Variants Compared to Full-Length Long Signals [PDF]

open access: yesEntropy, 2021
Multiscale entropy (MSE) analysis is a fundamental approach to access the complexity of a time series by estimating its information creation over a range of temporal scales. However, MSE may not be accurate or valid for short time series.
