###VAT for supervised learning on MNIST dataset

python train_mnist_sup.py --cost_type=VAT_finite_diff --epsilon=2.1 --layer_sizes=784-1200-600-300-150-10 --save_filename=<filename>

###VAT for semi-supervised learning on MNIST dataset (with 100 labeled samples)

python train_mnist_semisup.py --cost_type=VAT_finite_diff --epsilon=0.3 --layer_sizes=784-1200-1200-10 --num_labeled_samples=100 --save_filename=<filename>

After finish training, the trained classifer will be saved with <filename> in ./trained_model.

You can obtain a test error of the trained classifier saved with <filename> by the following command:

python test_mnist.py --load_filename=<filename>
