Cross-View Feature Learning via Structures Unlocking Based on Robust Low-Rank Constraint
IEEE Access, 2020 The cross-view multimedia are widely existed and attract many attentions in recent years. Nevertheless, it is noted that the phenomenon, that data in different classes from same view are more similar than that in same class from different views, is ...
