SCGAN

The search code will be published once the paper is accepted, and the training code and network weights will be published immediately.

Code used for "SCGAN: Sampling and Clustering-based Neural Architecture Search for GANs".

Introduction

We've desinged a evolutionary neural architecture search algorithm for generative adversarial networks (GANs), dubbed SCGAN. Experiments validate the effectiveness of SCGAN on the task of unconditional image generation. Extensive experiments on the CIFAR-10 and STL-10 datasets demonstrated that T-EAGAN only requires 0.42 GPU days to find out a superior GAN architecture in a search space including approximately 10¹⁵ network architectures. Our best-found GAN outperformed those obtained by other neural architecture search methods with performance metric results (IS=9.68±0.06, FID=5.54) on CIFAR-10 and (IS=12.12±0.13, FID=12.54) on STL-10.

Set-Up

1.environment requirements:

The search environment is consistent with AlphaGAN，to run this code, you need:

• PyTorch 2.0
• TensorFlow 2.12.0
• cuda 12.0

Other requirements are in environment.yaml

conda env create -f environment.yaml

2.prepare fid statistic file

you need to create "fid_stat" directory and download the statistical files of real images.

mkdir fid_stat

How to search the architecture by yourself

1. Search on CIFAR-10

bash EAGAN_Only_G30.sh

How to train the discovered architecture reported in the paper

1. Fully train GAN on CIFAR-10

bash ./scripts/train_arch_cifar10.sh

2. Fully train GAN on STL-10

bash ./scripts/train_arch_stl10.sh

How to test the discovered architecture reported in the paper

1. Fully train GAN on CIFAR-10

bash ./scripts/test_arch_cifar10.sh

2. Fully train GAN on STL-10

bash ./scripts/test_arch_stl10.sh
