An end-to-end framework combining time–frequency expert knowledge and modified transformer networks for vibration signal classification

作者:

Highlights:

• The proposed end-to-end framework combined expert knowledge and deep neural networks.

• The Transformer network was modified to fit time–frequency features extraction.

• Multi-sensor fusion improved the performance without much extra computation cost.

• Joint optimization was realized throughout the framework to avoid human intervene.

• The proposed framework has potential broad applicability on different vibration signals.
