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.

@AITTSMD 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，
