Classification of Motor Imagery BCI Using Multivariate Empirical Mode Decomposition [PDF]

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2013
Brain electrical activity recorded via electroencephalogram (EEG) is the most convenient means for brain-computer interface (BCI), and is notoriously noisy. The information of interest is located in well defined frequency bands, and a number of standard frequency estimation algorithms have been used for feature extraction.

On the behavior of EMD and MEMD in presence of symmetric alpha-stable noise [PDF]

open access: yes, 2014
EmpiricalMode Decomposition (EMD) and its extended versions such as Multivariate EMD (MEMD) are data-driven techniques that represent nonlinear and non-stationary data as a sum of a finite zero-mean AM-FM components referred to as Intrinsic Mode ...

Chaotic signals denoising using empirical mode decomposition inspired by multivariate denoising [PDF]

open access: yes, 2020
Empirical mode decomposition (EMD) is an effective noise reduction method to enhance the noisy chaotic signal over additive noise. In this paper, the intrinsic mode functions (IMFs) generated by EMD are thresholded using multivariate denoising ...
