Training Dataset

• MNIST
• Fashion-MNIST
• CIFAR 10
• LLD(Large Logo Dataset)

Results

• GAN, LSGAN, WGAN are have same generator and discriminator CNN structure.
• No data augmentation.

WGAN result - after training LLD dataset for 5 epoch

Observation

1. MNIST dataset is easy for GAN, LSGAN, WGAN.
2. Training with Fashion-MNIST dataset, GAN is slightly better others.
3. Training with CIFAR 10 dataset, WGAN are better than others. but clearly does not generate looks pretty image like original image.
4. Training with LLD dataset, three GANs generate similar image. Compare with original image, three GANs generate ugly image.

Compare other GANs, WGAN generate best image in less epoch, but after 5 epoch generate worse than others.

Above loss of generator and discriminator, generator overpowered discriminator.

GANs trained outline of all original dataset(fashion-mnist, CIFAR10, LLD), but did not train detail.

Getting Started

1. python ./setup.py install and follow console (If you already installed dependencies, follow step 2.)
2. Run bench code python ./main.py
3. If you want to run another instance, modify workbench/bench_code.py.
