softmax loss provides roughly separable feature embedding but produces noticeable ambiguity in decision boundaries, while the proposed ArcFace loss can obviously enforce a more evident gap between the nearest classes. 2.2. Comparison with SphereFace and CosFace Numerical Similarity. In SphereFace [15, 16], ArcFace,

In this paper, we propose an Additive Angular Margin Loss (ArcFace) to obtain highly discriminative features for face recognition. The proposed ArcFace has a clear geometric interpretation due to the exact correspondence to the geodesic distance on the hypersphere. We present arguably the most extensive experimental evaluation of all the recent ...

Dec 17, 2019 · ArcFace is indeed a loss function. If you go through the research paper, the authors have mentioned that they use the traditional softmax function as an activation function for the last layer. (You can checkout the call function is metrics.py file. The last line is out = tf.nn.softmax (logits) ).
