Weighted quantile discrepancy-based deep domain adaptation network for intelligent fault diagnosis

作者:

Highlights:

• A novel WQD metric is proposed to measure the discrepancy of distributions.

• It is then introduced to develop a DWQDAN model for intelligent fault diagnosis.

• The weights in DWQDAN are flexible to focus on different quantiles of distributions.

• The efficacy of DWQDAN is illustrated by the public CWRU and Paderborn datasets.

• The results show the DWQDAN model is promising and suitable for fault diagnosis.
