Fast ResNet for CIFAR

This ResNet spends 3 hours to train on a modern CPU. It can reach 63% on CIFAR100 coarse 20 classes task.
This residual neural network is different from the original paper in there ways:

  • Only have 13 layers, which the original paper didn't studied.
  • No ReLU before subsampling convolutional layer, which improve accuracy by 3%
  • BatchNorm is done before addition, which improve accuracy a little bit.

This ResNet-13 can't beat ResNet-18/34/150/1000 layers residual nets in the long run, however, more efficient with non-sufficient training time, interestingly.
Details are shown here. Archtecture shown at the bottom.
