This paper addresses the deep face recognition problem under an open-set protocol, where ideal face features are expected to have smaller maximal intra-class distance than minimal inter-class distance under a suitably chosen metric space. To this end, hyperspherical face recognition, as a promising line of research, has attracted increasing attention and gradually become a major focus in face recognition research. As one of the earliest works in hyperspherical face recognition, SphereFace… 

Unifying Margin-Based Softmax Losses in Face Recognition

A theoretical and experimental framework to study the effect of margin penalties on angular softmax losses, which have led to state-of-the-art performance in face recognition, and a new multiplicative margin which performs comparably to previously proposed additive margins when the model is trained to convergence.

A novel negative sampling solution based on dynamic policy switching, referred to as negative sampling probability annealing, which aims to exploit the positives of all approaches.

Continual Learning by Modeling Intra-Class Variation

This work examines memory-based continual learning and identifies that large variation in the representation space is crucial for avoiding catastrophic forgetting and proposes to diversify representations by using two types of perturbations: model-agnostic variation and model-based variation.

Just Noticeable Difference Modeling for Face Recognition System

This work develops a novel JND prediction model to directly infer JND images for the FR system and achieves higher accuracy of JND map prediction compared with the state-of-the-art JND models, and is capable of saving more bits while maintaining the performance of theFR system compared with VTM-15.0.

Structural Causal 3D Reconstruction

This paper restricts the structure of latent space to capture a topological causal ordering of latent factors and demonstrates that the latent space structure indeed serves as an implicit regularization and introduces an inductive bias beneficial for reconstruction.

SphereFace2: Binary Classification is All You Need for Deep Face Recognition

This paper identifies the discrepancy between training and evaluation in the existing multi-class classification framework and discusses the potential limitations caused by the “competitive” nature of softmax normalization, and proposes a novel binary classification training framework, termed SphereFace2, which effectively bridges the gap betweenTraining and evaluation.

This paper reformulates the softmax loss as a cosine loss by L2 normalizing both features and weight vectors to remove radial variations, based on which acosine margin term is introduced to further maximize the decision margin in the angular space, and achieves minimum intra-class variance and maximum inter- class variance by virtue of normalization and cosine decision margin maximization.
