sphereface #5

What did you mean by sphereface? is it Asoftmax or L-Margin or Isoftmax ? because I think it's not same as Asoftmax ... If yes did you test it and get similar behavior to the original one

nttstar commented 6 years ago

I just normalized the weight and then use L-Margin(L-Softmax). It equals to ASoftmax logically.

Just I want to test combine both of ASoftmax and Triplet... did you test it before? Thanks

nttstar commented 6 years ago

Yes it works. You need to train ASoftmax firstly and finetune it by triplet with semi-hard mining. It brings +0.2 acc on my previous megaface top1 test.

What is your highest accuracy you have got on Megaface, and which loss did you use?

nttstar commented 6 years ago

We will publish all experiment results, dataset and training scripts/notes soon.
