TLDR
Wang et al. as mentioned in this paper proposed a deep learning based large-scale bisample learning (LBL) method for ID versus Spot (IvS) face recognition, where a classification-verification-classification training strategy is proposed to progressively enhance the IvS performance.Abstract:
In real-world face recognition applications, there is a tremendous amount of data with two images for each person. One is an ID photo for face enrollment, and the other is a probe photo captured on spot. Most existing methods are designed for training data with limited breadth (a relatively small number of classes) and sufficient depth (many samples for each class). They would meet great challenges on ID versus Spot (IvS) data, including the under-represented intra-class variations and an excessive demand on computing devices. In this paper, we propose a deep learning based large-scale bisample learning (LBL) method for IvS face recognition. To tackle the bisample problem with only two samples for each class, a classification–verification–classification training strategy is proposed to progressively enhance the IvS performance. Besides, a dominant prototype softmax is incorporated to make the deep learning scalable on large-scale classes. We conduct LBL on a IvS face dataset with more than two million identities. Experimental results show the proposed method achieves superior performance to previous ones, validating the effectiveness of LBL on IvS face recognition.read more

AdaptiveFace: Adaptive Margin and Sampling for Face Recognition
TL;DR: This paper proposes the Adaptive Margin Softmax to adjust the margins for different classes adaptively, and makes the sampling process adaptive in two folds: Firstly, the Hard Prototype Mining to adaptively select a small number of hard classes to participate in classification, and secondly, theAdaptive Data Sampling to find valuable samples for training adaptively.

Learning Meta Face Recognition in Unseen Domains
TL;DR: This paper proposes a novel face recognition method via meta-learning named Meta Face Recognition (MFR), which synthesizes the source/target domain shift with a meta-optimization objective, which requires the model to learn effective representations not only on synthesized source domains but also on synthesizer target domains.

Occluded Face Recognition in the Wild by Identity-Diversity Inpainting
TL;DR: This paper proposes identity-diversity inpainting to facilitate occluded face recognition by integrating GAN with an optimized pre-trained CNN recognizer which serves as the third player to compete with the generator by distinguishing diversity within the same identity class.
