3.4 测试cpu gpu影响

TEST: scale/kernel ToyNet

修改网络的卷积层深度,并进行训练,可以得到以下结论:

结论:lenet这种卷积量比较少,只有两层的,cpu利用率高,gpu利用率低。在这个基础上增加深度,用vgg那种直筒方式增加深度,发现深度越深,cpu利用率越低,gpu利用率越高。

修改训练过程的batch size,可以得到以下结论:

结论:bs会影响收敛效果。

3.5 StepLR优化下测试cutout和mixup

architecture epoch cutout mixup C10 test acc (%)
shake_resnet26_2x64d 200 96.33
shake_resnet26_2x64d 200 96.99
shake_resnet26_2x64d 200 96.60
shake_resnet26_2x64d 200 96.46

3.6 测试SAM,ASAM,Cosine,LabelSmooth

architecture epoch SAM ASAM Cosine LR Decay LabelSmooth C10 test acc (%)
shake_resnet26_2x64d 200 96.51
shake_resnet26_2x64d 200 96.80
shake_resnet26_2x64d 200 96.61
shake_resnet26_2x64d 200 96.57

PS:其他库在加长训练过程(epoch=1800)情况下可以实现 shake_resnet26_2x64d achieved 97.71% test accuracy with cutout and mixup!!

3.7 测试cosine lr + shake

architecture epoch cutout mixup C10 test acc (%)
shake_resnet26_2x64d 300 96.66
shake_resnet26_2x64d 300 97.21
shake_resnet26_2x64d 300 96.90
shake_resnet26_2x64d 300 96.73

1800 epoch CIFAR ZOO中结果,由于耗时过久,未进行复现。

architecture epoch cutout mixup C10 test acc (%)
shake_resnet26_2x64d 1800 96.94(cifar zoo)
shake_resnet26_2x64d 1800 97.20(cifar zoo)
shake_resnet26_2x64d 1800 97.42(cifar zoo)
shake_resnet26_2x64d 1800 97.71(cifar zoo)

3.8 Divide and Co-training方案研究

  • lr:
    • warmup (20 epoch)
    • cosine lr decay
    • lr=0.1
    • total epoch(300 epoch)

    • Random left-right flipping
    • AutoAugment
    • Normalization
    • Random Erasing
    • Mixup
  • weight decay=5e-4 (bias and bn undecayed)
