说实话,这个损失函数的效果并没有论文说的那么好,感觉还是原始的arcface的比较work。
建议使用arcface

你用的什么网络训练的,使用的什么数据,数据规模多大?

除了 lost adaface 不一样 ,其他都一样的情况下,收敛速度loss好慢啊,

Iteration 12000次 loss 从16.4 降到14.9 正常吗, 其他的loss 早就降到loss=1.0以内了

我自己训练的时候,acc=0.98左右, loss = 5.8左右,感觉是有点不是很正常,loss太高了。
测试效果也是不理想,参考别人的论文以及看法,这个损失函数确实有水分。

loss 开始高 没有关系,跟数据有关系,主要是降的太慢,又回到loss=15.1,晚上跑一晚上看看,能不能降到1以内

大神我用arcface 训练三天三夜,acc=0.984. loss=1.x 有什么办法让acc=0.99+ 不改变训练的数据情况下

可以试一下调整动量momentum。

大神 昨晚把动量从0.92调到0.9 m 0.35->0.4 acc=0.99 不知道收敛到0.996+

@wavelet2008 你们说的acc是fc6层作为输入的acc么?请问训练过程中AdaCosAddmScale的acc大概能到多少
