摘要

（1）Center loss: The method learns the centers of deep features for each class while penalizing the distances between the deep features and their corresponding class centers.
（2）Center loss is learnable and straightforward to optimize.
（3）The joint supervision of normalized exponential margin-based losses and center loss ensures in
