WebMay 8, 2024 · Answers (2) Harsha Priya Daggubati on 11 May 2024. Hi, Currently there is no support for arcface or sphereface loss in MATLAB. cui on 21 Nov 2024. cui on 13 Jan 2024. please reference here: Web它与前面提到的L-sofrmax最大的区别在于SphereFace将W权重归一化了。 L-Softmax会同时从角度和权重长度上区分不同类别,而SphereFace只从角度上去区分不同类别,在数据集大小固定的条件下,L-softmax的精确度可能不如sphereFace。
