a re-implementation of asoftmax in tensorflow
what is the meaning of 'f' and 'ff' ? 0.5???
Since m=3 hasn't been implemented, will you please provide the formula for that.
cos_sign = tf.sign(cos_th) res = 2*tf.multiply(tf.sign(cos_th), tf.square(cos_th)) - 1 what's the mean of the sign function in calculate the cos(m*th)
I tried to reproduce sphereface via tensorflow on CASIA-WebFace, but I found the loss function is very difficult to convey, and loss function sometimes be very large (10e6). Are there...
I tested your code for 20-layer setting of Sphereface paper with the CNN and residual units but the loss value for m=4 became weirdly huge.
Hi author. There is a new published paper proposed additive margin softmax(AM-softmax), which seems easier to train than sphereface. https://arxiv.org/abs/1801.05599 I implemented main part of this paper here by tensorflow:...
