Query: GB-CosFace: Rethinking Softmax-based Face Recognition from the
  Perspective of Open Set Classification   State-of-the-art face recognition methods typically take the
multi-classification pipeline and adopt the softmax-based loss for
optimization. Although these methods have achieved great success, the
softmax-based loss has its limitation from the perspective of open set
classification: the multi-classification objective in the training phase does
not strictly match the objective of open set classification testing. In this
paper, we derive a new loss named global boundary CosFace (GB-CosFace). Our
GB-CosFace introduces an adaptive global boundary to determine whether two face
samples belong to the same identity so that the optimization objective is
aligned with the testing process from the perspective of open set
classification. Meanwhile, since the loss formulation is derived from the
softmax-based loss, our GB-CosFace retains the excellent properties of the
softmax-based loss, and CosFace is proved to be a special case of the proposed
loss. We analyze and explain the proposed GB-CosFace geometrically.
Comprehensive experiments on multiple face recognition benchmarks indicate that
the proposed GB-CosFace outperforms current state-of-the-art face recognition
losses in mainstream face recognition tasks. Compared to CosFace, our
GB-CosFace improves 1.58%, 0.57%, and 0.28% at TAR@FAR=1e-6, 1e-5, 1e-4 on
IJB-C benchmark.
