Fisrtly,thank you for sharing the loss code and model architecture,it's a very nice work!! In you paper,in the table 5,you only compare the margin value of arcface loss! image

I can't find the scale and margin value when use ArcNegFace Loss,so is there has the optimal scale and margin value when choose ArcNegFace Loss? @liuyuisanai @songguanglu

In our experiments, we find that the hyper-pyrameters such as scale and margin in ArcFace can be directly applied to ArcNegFace. In our experiments, the scale is set to 64 as used in ArcFace Paper and for the margin, we compare the performance between margin 0.5 and 0.3.
