Elimination of End effects in LMD Based on LSTM Network and Applications for Rolling Bearing Fault Feature Extraction

<div>Analysis of local envelope for a simulated signal (solid blue line): (a) using the endpoint as the extremum of the local envelope waveform (dashed red line); (b) real local mean waveform obtained using the extension signal (dashed green); (c) difference between the two local envelope waveforms.</div>
