Web1. apr 2024 · (1) We provide an analysis of the margin-based softmax loss and conclude four key properties from the three aspects of gradient, feature, and optimization. (2) We carefully design a sampling distribution based on the non-independent truncated Gaussian distributions, through which the sampled loss function conforms to the above four … WebGeometrically, A-Softmax loss can be viewed as imposing discriminative constraints on a hypersphere manifold, which intrinsically matches the prior that faces also lie on a mani- fold. Moreover, the size of angular margin can be quantita- tively adjusted by a parameter m. We further derive specific mto approximate the ideal feature criterion.
