Self-Supervised GAN

Implementation of the paper:

Bingchen Liu, Yizhe Zhu, Kunpeng Song and Ahmed Elgammal. Towards Faster and Stabilized GAN Training for High-fidelity Few-shot Image Synthesis.

See here for the official Pytorch implementation.

Examples

Dependencies

• Python 3.8
• Tensorfow 2.8
• Tensorflow Addons 0.16

Usage

Train

Use --file_pattern=<file_pattern> to provide the dataset path and file pattern.

python train.py --file_pattern=./dataset_path/*.png

Generate

Use --main_dir=<main_dir> to provide the model directory name.

python generate.py --main_dir=<main_dir>

Hparams setting

Adjust hyperparameters on the hparams.py file.

Tensorboard

Run tensorboard --logdir ./.
