In other words, time to train a DL network can be accelerated by as much as 57x (resnet 50) and 58x (inception V3) using 64 Xeon nodes comparing to a single Xeon node. It is a 50-layer deep neural network architecture based on residual connections, which are connections that add modifications with each layer, rather than completely changing the signal. DAWNBench is a benchmark suite for end-to-end deep learning training and inference. Wide ResNet-50-2 model from “Wide Residual Networks” The model is the same as ResNet except for the bottleneck number of channels which is twice larger in every block. This is an Keras implementation of ResNet-152 with ImageNet pre-trained weights. The model consists of a deep convolutional net using the ResNet-50 architecture that was trained on the ImageNet-2012 data set. 前からディープラーニングのフレームワークの実行速度について気になっていたので、ResNetを題材として比較してみました。今回比較するのはKeras（TensorFlow、MXNet）、Chainer、PyTorchです。ディープラーニングのフレームワーク選びの参考になれば幸いです。. 72 accuracy in 5 epochs (25/minibatch).
