An Empirical Study on GANs with Margin Cosine Loss and Relativistic Discriminator
This is a Pytorch implementation for the paper "An Empirical Study on GANs with Margin Cosine Loss and Relativistic Discriminator".
Requirement
- python 3.7.3
- pytorch 1.2.0
- tensorflow 2.0.0
- torchtext 0.4.0
- torchvision 0.4.0
- mnist
Data preparation
- Run 0_prepare_dataset.py to automatically download, process and store images of CIFAR10, STL10, MNIST datasets. CAT dataset can be downloaded here.
- Download FID stats for CIFAR-10 at http://bioinf.jku.at/research/ttur/ttur_stats/fid_stats_cifar10_train.npz
Training
- Run 1_train.sh to train our proposed loss function RMCosGAN along with other loss functions on four datasets.
