WebNov 25, 2016 · Komaty et al. suggested a signal-filtering approach based on a combination of EMD and a similarity measure for noise removal. Park et al. ( 2015 ) applied a quantile smoothing method to a signal itself instead of interpolating local extrema of a signal for sifting. WebIn addition, we employ the EMD method to remove signal trends from the original signal and generate another type of MBE, called S-MBEs, using FFT and a Mel filter bank. Four different datasets were utilised and convolutional neural networks (CNN) were trained using features extracted from Fourier transform-based MBEs (FFT-MBEs), EMD-MBEs, and S ...
