An pytorch implementation of paper 'Be Your Own Teacher: Improve the Performance of Convolutional Neural Networks via Self Distillation', https://arxiv.org/abs/1905.08094

Introduction

We provide code of training ResNet18 and ResNet50 with multiple breanches on CIFAR100 dataset.

Dependencies:

Python 3.5.2
PyTorch 1.2.0
torchvision 0.4.0
numpy 1.17.2
tensorboardX 1.8

Note: this is my machine environment, and the other version of software may also works.

Train an ResNet on CIFAR-100:

python train.py train multi_resnet18_kd \
                             --data-dir /PATH/TO/CIFAR100

Load an ResNet on CIFAR-100 and test it:

python train.py test multi_resnet18_kd \
                             --data-dir /PATH/TO/CIFAR100 
                             --resume /PATH/TO/checkpoint

Result on Resnet18

As the original paper does not tell us the hyper-parameters, I just use the follow setting. If you find better hyper-parmeters, you could tell me in the issues. Moreover, we do not konow the side-branch architecture details. So the accuracy is lower than the original paper. I will fine-tune the hyper-parameters.

alpha = 0.1
temperature = 3
beta = 1e-6
