Chongxuan Li, Kun Xu, Jun Zhu and Bo Zhang

Code for reproducing most of the results in the paper. Triple-GAN: a unified GAN model for classification and class-conditional generation in semi-supervised learning.

Warning: the code is still under development.

Envoronment settings and libs we used in our experiments

This project is tested under the following environment setting.

  • OS: Ubuntu 16.04.3
  • GPU: Geforce 1080 Ti or Titan X(Pascal or Maxwell)
  • Cuda: 8.0, Cudnn: v5.1 or v7.03
  • Python: 2.7.14(setup with Miniconda2)
  • Theano:
  • Lasagne: 0.2.dev1
  • Parmesan: 0.1.dev1

Python Numpy Scipy Theano Lasagne(version 0.2.dev1) Parmesan

Thank the authors of these libs. We also thank the authors of Improved-GAN and Temporal Ensemble for providing their code. Our code is widely adapted from their repositories.


Triple-GAN can achieve excellent classification results on MNIST, SVHN and CIFAR10 datasets, see the paper for a comparison with the previous state-of-the-art. See generated images as follows:
