This repo contains demo reimplementations of the CIFAR-10 training code and the GAN experiment in PyTorch based on the following paper:

Hongyi Zhang, Moustapha Cisse, Yann N. Dauphin and David Lopez-Paz. mixup: Beyond Empirical Risk Minimization. https://arxiv.org/abs/1710.09412

CIFAR-10

The following table shows the median test errors of the last 10 epochs in a 200-epoch training session. (Please refer to Section 3.2 in the paper for details.)

Model	weight decay = 1e-4	weight decay = 5e-4
ERM	5.53%	5.18%
mixup	4.24%	4.68%

Generative Adversarial Networks (GAN)

Other frameworks

• A Tensorflow implementation of mixup which reproduces our results in tensorpack
