Keras VAEs and GANs

Keras implementation of various deep generative networks such as VAE and GAN.

Models

Standard models

• Variational autoencoder (VAE) [Kingma et al. 2013]
• Generative adversarial network (GAN or DCGAN) [Goodfellow et al. 2014]
• Improved GAN [Salimans et al. 2016]
• Energy-based GAN (EBGAN) [Zhao et al. 2016]
• Adversarially learned inference (ALI) [Dumoulin et al. 2017]

Conditional models

• Conditional variational autoencoder [Kingma et al. 2014]
• CVAE-GAN [Bao et al. 2017]

Usage

Prepare datasets

First, download img_align_celeba.zip and list_attr_celeba.txt from CelebA webpage. Then, place these files to datasets and run create_database.py on databsets directory.

Training

# Standard models
python train.py --model=dcgan --epoch=200 --batchsize=100 --output=output

# Conditional models
python train_conditional.py --model=cvaegan --epoch=200 --batchsize=100 --output=output
