First of all, through a multi-scale hybrid dilated convolutional feature extraction module, highly abstract sample features are extracted from a vibration signal acquired in a complex scenario.

In addition, a new similarity evaluation method, namely a central difference metric (CDM), is proposed to calculate a difference between the internal structures of the data, providing a more flexible similarity evaluation tool for a few-shot diagnosis task.
