This project is aimmed at implementing the CosFace described by the paper CosFace: Large Margin Cosine Loss for Deep Face Recognition. The code can be trained on CASIA-Webface and the best accuracy LFW is 98.6%. The result is lower than reported by paper(99.33%), which may be caused by sphere network implemented in tensorflow. I train the sphere network implemented in tensorflow using the softmax loss and just obtain the accuracy 95.6%, which is more lower than caffe version(97.88%). I supply the preprocessed dataset in baidu pan:CASIA-WebFace-112X96,lfw-112X96. You can download and unzip them to dir dataset.
