The aim of unsupervised domain adaptation is to leverage the knowledge in a labeled (source) improve model’s learning performance with an unlabeled (target) domain—the basic strategy being mitigate effects discrepancies between two distributions. Most existing algorithms can only handle closed set (UCSDA), i.e., where source and target domains are assumed share same label set. In this article, ...

The existing iris recognition methods offer excellent performance for known classes, but they do not consider the rejection of unknown classes. It is important to reject an object class a reliable system. This study proposes open-set based on deep learning. In method, by training network, extracted features are clustered near feature centre each kind image. Then, authors build open-class outlie...
