One of the main challenges for feature representation in deep learning-based
classification is the design of appropriate loss functions that exhibit strong
discriminative power. The classical softmax loss does not explicitly encourage
discriminative learning of features. A popular direction of research is to
incorporate margins in well-established losses in order to enforce extra
intra-class compactness and inter-class separability, which, however, were
developed through heuristic means, as opposed to rigorous mathematical
principles. In this work, we attempt to address this limitation …
