TVT: Transferable Vision Transformer for Unsupervised Domain Adaptation, WACV 2023

updates (03/10/2022)

1. Add the environment requirements to reproduce the results.

2. Add the attention visualization code. An example is as follows where att_visual.txt contains image pathes:

python3 visualize.py --dataset office --name dw --num_classes 31 --image_path att_visual.txt --img_size 256

More details can be found in Attention Map Visualization

updates (03/08/2022)

Add the source-only code. An example on Office-31 dataset is as follows, where dslr is the source domain, webcam is the target domain:

python3 train.py --train_batch_size 64 --dataset office --name dw_source_only --train_list data/office/dslr_list.txt --test_list data/office/webcam_list.txt --num_classes 31 --model_type ViT-B_16 --pretrained_dir checkpoint/ViT-B_16.npz --num_steps 5000 --img_size 256

Pretrained ViT

Download the following models and put them in checkpoint/

• ViT-B_16 (ImageNet-21K)
• ViT-B_16 (ImageNet)

TVT with ViT-B_16 (ImageNet-21K) performs a little bit better than TVT with ViT-B_16 (ImageNet):

Datasets:

• Download data and replace the current data/

• Download images from Office-31, Office-Home, VisDA-2017 and put them under data/. For example, images of Office-31 should be located at data/office/domain_adaptation_images/

Training:

All commands can be found in script.txt. An example:

python3 main.py --train_batch_size 64 --dataset office --name wa \
--source_list data/office/webcam_list.txt --target_list data/office/amazon_list.txt \
--test_list data/office/amazon_list.txt --num_classes 31 --model_type ViT-B_16 \
--pretrained_dir checkpoint/ViT-B_16.npz --num_steps 5000 --img_size 256 \
--beta 0.1 --gamma 0.01 --use_im --theta 0.1

Attention Map Visualization:

python3 visualize.py --dataset office --name wa --num_classes 31 --image_path att_visual.txt --img_size 256

The code will automatically use the best model in wa to visualize the attention maps of images in att_visual.txt. att_visual.txt contains image pathes you want to visualize, for example:

/data/office/domain_adaptation_images/dslr/images/calculator/frame_0001.jpg 5
/data/office/domain_adaptation_images/dslr/images/calculator/frame_0002.jpg 5
/data/office/domain_adaptation_images/dslr/images/calculator/frame_0003.jpg 5
/data/office/domain_adaptation_images/dslr/images/calculator/frame_0004.jpg 5
/data/office/domain_adaptation_images/dslr/images/calculator/frame_0005.jpg 5
