Training without alignment

Dear @happynear, first of all thanks for your work and uploaded results! I would like to ask about alignment step, is it really important to get good performance? I have not tried your code ( will do it this week ), but tried ResNet-18 with VGG2 without alignment step. SoftMax and CenterLoss gave about 90% both, CenterLoss also provided much better localization, but surprisingly ArcFace result was 70% only, I will try CosFace this week but I expect more or less the same. Did you try to train something without alignment?
Thank you! I will post my result with CosFace
