Various_softmax_by_Keras

Keras implementation of various loss functions in face recognition and visualization on Mnist

Requirements

• tensorflow 1.5
• keras 2.2.0
• some common packages like numpy and so on.

Quick start

• Now we support original softmax, center loss, A-softmax and AM-softmax.
• Just change the loss_name in keras_mnist_loss_compare.py

loss_name = 'AM-softmax'
