Insight Face on TensorFlow

Insight Face in TensorFlow

Tasks

• mxnet dataset to tfrecords
• backbone network architectures [vgg16, vgg19, resnet]
• backbone network architectures [resnet-se, resnext]
• LResNet50E-IR
• LResNet100E-IR
• Additive Angular Margin Loss
• CosineFace Loss
• train network code
• add validate during training
• multi-gpu training
• combine losses contributed by RogerLo.
• evaluate code

Training Tips(Continual updates)

• If you can't use large batch size(>128), you should use small learning rate
• If you can't use large batch size(>128), you can try batch renormalization(file L_Resnet_E_IR_RBN.py)
• If use multiple gpus, you should keep at least 16 images each gpu.
• Try Group Normalization, you can use the code L_Resnet_E_IR_GBN.py
• Using the current model, and the lr schedule in train_nets.py, you can get the results as model c
• The bug about model size is 1.6G have fixed based on issues #9. If you want to get a small model, you should use L_Resnet_E_IR_fix_issues9.py
• multi-gpu training code's bug have fixed. If you want to use the correct version, you should use train_nets_mgpu_new.py
