KappaFace: Adaptive Additive Angular Margin Loss for Deep Face Recognition. (arXiv:2201.07394v1 [cs.CV])

Feature learning is a widely used method employed for large-scale face
recognition. Recently, large-margin softmax loss methods have demonstrated
significant enhancements on deep face recognition. These methods propose fixed
positive margins in order to enforce intra-class compactness and inter-class
diversity. However, the majority of the proposed methods do not consider the
class imbalance issue, which is a major challenge in practice for developing
deep face recognition models. We hypothesize that it significantly affects the
generalization ability of the deep face …
