How to debug margin and scale?

[AITTSMD]

Hi, thanks for your great job. I wonder how I can debug the value of margin and scale to get better result.I use the default setting(m=0.35, scale=30)on my face recognition dataset, the final training loss is about 3 and it can't decrease. So I come here to ask the quesion, thank you~

The final loss value in AM-Softmax is meaningless. It doesn't matter what the final loss is.

@happynear okay，thank you~Can you explain the meaning of scale？How to adjust the value of scale to get better result?

您好，
请问我想用 arcface 损失函数是将您的caffe 版本中的 将这一层， name: "label_specific_margin"
type: "LabelSpecificAdd" type改动，LabelSpecificHardMargin, 不需要参数设置，
