mobilefacenet-V2

now we get more higher accuray:

[lfw][12000]Accuracy-Flip: 0.99667+-0.00358
[agedb_30][12000]Accuracy-Flip: 0.96667+-0.00167 use my modified mobilenet network.

improve the accuracy of mobilefacenet in paper mobilefacenet论文(https://arxiv.org/abs/1804.07573)

First step training (use softmax to pretrain): train softmax(facenet):

Update wd=0.00001 , --fc7-wd-mult 10 --emb-size 512 i get new Accuracy:
