This is a pytorch implementation of the paper On Leveraging Pretrained GANs for Limited-Data Generation.

Please consider citing our paper if you refer to this code in your research.

Requirement

python=3.7.3
pytorch=1.2.0

Notes

CELEBA_[f]GmDn.py is the implementation of the model in Figure1(f).

Flower_[h]our.py is the implementation of the model in Figure1(h). This code is for "Section 4.1 Comparisons with Existing Methods".

Flower25_our.pyis the code for the experiments on Flowers-25.

Usage

First, download the pretrained GP-GAN model by running download_pretrainedGAN.py. Note please change the path therein.

Second, download the training data to the folder ./data/. For example, download the Flowers dataset from: https://www.robots.ox.ac.uk/~vgg/data/flowers/102/ to the folder ./data/102flowers/. For Flowers-25, we choose the first 25 images from the passion category, following Image Generation from Small Datasets via Batch Statistics Adaptation.
