I wonder if it is possible to use the universal threshold b proposed in SphereFace2 as an actual threshold? (Can it be used like the Threshold exemplified in Figure 2(b) of the paper?)
We set -b/r as the threshold and compared it with the similarity score. However, it does not yield good performance.
(We used universal threshold b obtained after training and r (in eq. 4))
If there are any related codes or methods, please let me know.
Thank you for the nice work!
