ArcFace parameter settings

[waaaaangchangwen]

Hi, Im wondering how you came up with the parameter of margin 0.7 and scale 30 in the ArcFace loss. Is there a rule to follow or just by testing different numbers?

It‘s also set as margin 0.7 and scale 30 in test.

Thanks for answering the question But what i mean is that how you choose this setting

Sorry, the margin and scale are the empirical values determined through experiments.
