This is a Pytorch implementation for the paper "An Empirical Study on GANs with Margin Cosine Loss and Relativistic Discriminator". https://arxiv.org/abs/2110.11293

• python 3.7.3
• pytorch 1.2.0
• tensorflow 2.0.0
• torchtext 0.4.0
• torchvision 0.4.0
• mnist

• 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

• Run 1_train.sh to train our proposed loss function RMCosGAN along with other loss functions on four datasets.
