2016 arXiv   pre-print
Our main technical contribution centers around a novel training method, called Multibatch, for similarity learning, i.e., for the task of generating an invariant "face signature" through training pairs  ...  This work is motivated by the engineering task of achieving a near state-of-the-art face recognition on a minimal computing budget running on an embedded system.  ...  We have shown that our multibatch method introduces a dramatic acceleration of the training time required to learn an effective embedding for the task of face recognition.  ...

Marginal Loss for Deep Face Recognition

Jiankang Deng, Yuxiang Zhou, Stefanos Zafeiriou
2017 2017 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)  
In order to enhance the discriminative power of the deeply learned features, we propose a new supervision signal named marginal loss for deep face recognition.  ...  Convolutional neural networks have significantly boosted the performance of face recognition in recent years due to its high capacity in learning discriminative features.  ...  Introduction Face representation through the deep convolutional network embedding is considered the state-of-the-art method for face verification, face clustering, and recognition [24, 18, 17] .  ...

Rethinking Feature Discrimination and Polymerization for Large-scale Recognition [article]

Yu Liu and Hongyang Li and Xiaogang Wang
2017 arXiv   pre-print
It inherits the softmax property to make inter-class features discriminative as well as shares the idea of class centroid in metric learning.  ...  Unlike previous work where the center is a temporal, statistical variable within one mini-batch during training, the formulated centroid is responsible for clustering inner-class features to enforce them  ...  The feature dimension is three for better illustration. The triplet loss [33] has a constraint on feature embedding ( f 2 = 1) and thus the learned features are scatted on a hypersphere.  ...
