TL;DR通过 KappaFace 算法和 von Mises-Fisher 分布相结合,提出了一种考虑类不平衡问题的大规模人脸识别方法,该算法有效提高了深度人脸识别的性能。
Abstract
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 p
