MNIST-to-SVHN and SVHN-to-MNIST

To train autoencoder for both MNIST and SVHN (In mnist_to_svhn folder): python main_autoencoder.py --use_augmentation=True

To train OST for MNIST to SVHN: python main_mnist_to_svhn.py --pretrained_g=True --save_models_and_samples=True --use_augmentation=True --one_way_cycle=True --freeze_shared=False

To train OST for SVHN to MNIST: python main_svhn_to_mnist.py --pretrained_g=True --save_models_and_samples=True --use_augmentation=True --one_way_cycle=True --freeze_shared=False

Drawing and Style Transfer Tasks

Download Dataset

To download dataset (in drawing_and_style_transfer folder): bash datasets/download_cyclegan_dataset.sh $DATASET_NAME where DATASET_NAME is one of (facades, cityscapes, maps, monet2photo, summer2winter_yosemite)

Train Autoencoder

To train autoencoder for facades (in drawing_and_style_transfer folder): python train.py --dataroot=./datasets/facades/trainB --name=facades_autoencoder --model=autoencoder --dataset_mode=single --no_dropout --n_downsampling=2 --num_unshared=2

In the reverse direction (images of facades): python train.py --dataroot=./datasets/facades/trainA --name=facades_autoencoder_reverse --model=autoencoder --dataset_mode=single --no_dropout --n_downsampling=2 --num_unshared=2

Train OST

To train OST for images to facades: python train.py --dataroot=./datasets/facades/ --name=facades_ost --load_dir=facades_autoencoder --model=ost --no_dropout --n_downsampling=2 --num_unshared=2 --start=0 --max_items_A=1

To train OST for facades to images (reverse direction): python train.py --dataroot=./datasets/facades/ --name=facades_ost_reverse --load_dir=facades_autoencoder_reverse --model=ost --no_dropout --n_downsampling=2 --num_unshared=2 --start=0 --max_items_A=1 --A='B' --B='A'

To visualize losses: run python -m visdom.server

Test OST

To test OST for images to facades: python test.py --dataroot=./datasets/facades/ --name=facades_ost --model=ost --no_dropout --n_downsampling=2 --num_unshared=2 --start=0 --max_items_A=1

To test OST for facades to images (reverse direction): python test.py --dataroot=./datasets/facades/ --name=facades_ost_reverse --model=ost --no_dropout --n_downsampling=2 --num_unshared=2 --start=0 --max_items_A=1 --A='B' --B='A'
