SNGAN-Projection Tensorflow

This is a Unofficial TF2.0 implementation of Spectral Normalization for Generative Adversarial Networks and cGANs with Projection Discriminator.

Official implementation is available here

Dataset

There are Food-101and MNIST training examples.

I found that it is easier to train 128 * 128 resolutions with dataset which has fewer classes and more examples. For example, I failed to train 64 * 64 res model with tiny-image-net(200 classes with 500 images in each classes) and stanford-dogs(120 classes with 20,580 images). However, I can get relative good result in Foods-101(101 classes and 101,000 images)

Environments

• Python 3
• jupyter or jupyterlab
• numpy
• matplotlib
• tensorflow 2.0

How to Run

1. Download the dataset you want.

2. Clone this repo, then use Juypter Notebook or Lab to open the *.ipynb file.

3. Modify the DATASET_PATH, and the parts with Needs to be modified in the Prepare dataset section.

Results

Foods:

• 128 * 128 resolutions
• batch size: 16
• noise dimension: 128
• 430k iterations

MNIST

• 28 * 28 resolutions
• batch size: 64
• noise dimension: 100
• 100k iterations
