gan-manifold-reg's Introduction

Manifold regularization with GANs for semi-supervised learning

This is the code we used in our paper

Manifold regularization with GANs for semi-supervised learning Bruno Lecouat*, Chuan Sheng Foo*, Houssam Zenati, Vijay Ramaseshan Chandrasekhar

Requirements

The repo supports python 3.5 + tensorflow 1.5

Run the Code

To reproduce our results on SVHN

python train_svhn.py

To reproduce our results on CIFAR-10

python train_cifar.py

Results

Here is a comparison of different models using standard architectures on several datasets (SVHN and CIFAR-10):

CIFAR(% errors) 1000 labels 4000 labels
Pi model 5.43 +/- 0.25 16.55 +/- 0.29
Mean Teacher 21.55 +/- 1.48 12.31 +/- 0.28
VAT large 14.18
FM 21.83 +/- 2.01 18.63 +/- 2.32
ALI 19.98 +/- 0.89 17.99 +/- 1.62
Bad GAN 14.41 +/- 0.30
Ours 16.37 +/- 0.42 14.34 +/- 0.17
SVHN (% errors) 500 labels 1000 labels
Pi model 7.05 +/- 0.30 5.43 +/- 0.25
Mean Teacher 4.35 +/- 0.50 3.95 +/- 0.19
VAT small 5.77
FM 18.44 +/- 4.80 8.11 +/- 1.30
ALI 7.41 +/- 0.65
Bad GAN 7.42 +/- 0.65
Ours 5.67 +/- 0.11 4.63 +/- 0.11
