Automatic feature extraction of time-series applied to fault severity assessment of helical gearbox in stationary and non-stationary speed operation

[Display omitted] •An automatic feature extraction method is proposed.•Manual feature extraction procedures can be replaced with deep learning approach.•Valid features can be extracted from a time-frequency representation of time-series.•A pre-trained layer by layer model is better than a model with...
