Non-parallel least squares support matrix machine for rolling bearing fault diagnosis
Mechanism and Machine Theory(2020)
摘要
•A novel matrix data classifier called NPLSSMM is proposed in this paper.•NPLSSMM can fully utilize the structure information of matrix data.•Wavelet time-frequency diagram is directly used as the input of NPLSSMM.•NPLSSMM has more excellent fault diagnosis performance.
