A Pytorch implementation of Center Loss & Contrastive-Center Loss.

(Thanks: https://github.com/jxgu1016/MNIST_center_loss_pytorch)

• A Discriminative Feature Learning Approach for Deep Face Recognition: https://ydwen.github.io/papers/WenECCV16.pdf

• Contrastive-center loss for deep neural networks: https://arxiv.org/abs/1707.07391

Modification/Addition:

• Implement Contrastive-Center Loss in addition to original one.
• Refactor and fix discrepancies between the paper and the implementation.
• Make calculation of center loss faster.
