WebArcFace, or Additive Angular Margin Loss, is a loss function used in face recognition tasks. The softmax is traditionally used in these tasks. However, the softmax loss function does not explicitly optimise the feature embedding to enforce higher similarity for intraclass samples and diversity for inter-class samples, which results in a performance gap for deep face … WebJan 23, 2024 · In this paper, we propose a novel supervisor signal, additive angular … WebNov 29, 2024 · Experimental results demonstrate the effectiveness of our proposed max margin cosine loss and superiority over pervious losses.

Webadditive cosine margin. ArcFace [14], proposed by InsightFace, introduces another additive margin, which directly adds the margin to the angle instead of to the cosine, so that the Webization, adding a margin can enhance the discrimination of features by inserting distance among samples of different classes. A-Softmax Loss [20] normalizes the weights and adds multiplicative angular margins to learn more divisi-ble angular characteristics. CosFace [35] adds an additive cosine margin to compress the features of the same class

WebIn SphereFace [9], the margin m is multiplied to θ, so the angular margin is incorporated into the loss in a multiplicative way.In our proposed loss function, the margin is enforced by subtracting m from cos θ, so our margin is incorporated into the loss in an additive way, which is one of the most significant differences than [9].It is also worth mentioning that … WebAll these improved losses share the same idea: maximizing inter-class variance and minimizing intra-class variance. In this paper, we propose a novel loss function, namely large margin cosine loss (LMCL), to realize this idea from a different perspective.
