This model is a re-implementation of Batch Normalization publication, and the model is trained with a customized caffe; however, the modifications are minor. Thus, you can run this with the currently available official caffe version, including cudnn v4 support and multigpu support.
The network definition and solver prototxt files are modified from https://github.com/BVLC/caffe/tree/master/models/bvlc_googlenet
Notes: - training with random crop; - training without any data-augmentation except random crop; - uses "xavier" to initialize the weights; - training with real-time shuffle with a modified data_reader.cpp; - ~~batch normalization layer is modified version of https://github.com/ChenglongChen/batch_normalization. The modified bn layer supports batch normalization for inference. (See neuron_layers.hpp, bn_layer.cpp, and bn_layer.cu)~~ - the official batch normalization layer is used and the usage of it is adopted from https://github.com/KaimingHe/deep-residual-networks. - use test_bn.cpp and predict_bn.cpp for inference. - use a mini-batch of 64 on 2 GPUs, i.e. 32 per GPU - use ILSVRC2015 labels, instead of 12' label. - Data (images) are resized with 256 x 256 convert_imageset.cpp.
The uploaded caffemodel is the snapshot of 1,200,000 iteration (30 epochs) using solverstepsize6400.prototxt
The uploaded model achieves a top-1 accuracy 72.05% (27.95% error) and a top-5 accuracy 90.87% (9.13% error) on the validation set, using a single center crop.
Thank John Lee for helping me training this model.
This model is released for unrestricted use.
