Abstract:The research of unsupervised cross-domain fault diagnosis for bearing is of great significance. However, there are still some problems to be solved. For example, a single predictor may not enough to acquire accurate pseudo-labels in target domain. In addition, global feature alignment may cause different subdomains of source and target domains to be too close. Finally, due to the inaccuracy of pseudo-labels, the effect of local subdomain feature alignment is also very limited. To this end, this paper proposes … Show more
