Acknowledgement

Our code is built on the GAN implmentation of Which Training Methods for GANs do actually Converge? [Mescheder et al. ICML 2018]. This repo adds the VGAN and instance noise implementations, along with FID computation.

Usage

First download your data and put it into the ./data folder.

To train a new model, first create a config script similar to the ones provided in the ./configs folder. You can then train you model using

python train.py PATH_TO_CONFIG

You can monitor the training with tensorboard:

tensorboard --logdir output/<MODEL_NAME>/monitoring/

Experiments

To generate samples, use

python test.py PATH_TO_CONIFG

You can also create latent space interpolations using

python interpolate.py PATH_TO_CONFIG
