Collections of GANs

Pytorch implementation of basic unsupervised GANs on CIFAR10.

For more defails about calculating Inception Score and FID using pytorch can be found here pytorch_gan_metrics.

Models

• DCGAN
• WGAN
• WGAN-GP
• SN-GAN

Requirements

• Install python packages

  pip install -U pip setuptools
  pip install -r requirements.txt

Results

The FID is calculated by 50k generated images and CIFAR10 train set.

Model	Dataset	Inception Score	FID
DCGAN	CIFAR10	6.01(0.05)	42.72
WGAN(CNN)	CIFAR10	6.62(0.09)	40.03
WGAN-GP(CNN)	CIFAR10	7.66(0.10)	19.83
WGAN-GP(ResNet)	CIFAR10	7.95(0.14)	16.95
SNGAN(CNN)	CIFAR10	7.84(0.12)	17.81
SNGAN(ResNet)	CIFAR10	8.31(0.10)	14.32

Examples

• DCGAN

  

• WGAN(CNN)

  

• WGAN-GP(CNN)

  

• WGAN-GP(ResNet)

  

• SNGAN(CNN)

  

• SNGAN(ResNet)

  

Reproduce

• Download cifar10.train.npz for calculating FID. Then, create folder stats for the npz files

  stats
  └── cifar10.train.npz
  

• Train from scratch

  Different methods are separated into different files for clear reading.
