Making the Best of Both Worlds: A Domain-Oriented Transformer for Unsupervised Domain Adaptation

Wenxuan Ma, Jinming Zhang, Shuang Li, , Chi Harold Liu, Yulin Wang, and Wei Li

Official implementation of our ACM MM 2022 paper "Making the Best of Both Worlds: A Domain-Oriented Transformer for Unsupervised Domain Adaptation" (DOT).

Framework Overview

In this work, we propose a new UDA paradigm that simultaneously learns multiple feature embedding spaces with their own different specification (denoted as domain-oriented feature spaces). The comparison between our new paradigm and the classical ones is shown in the figure.

Datasets Preparation

Office-Home

Office-home dataset can be download from here.

VisDA-2017

VisDA-2017 dataset can be download from here.

DomainNet

DomainNet dataset can be download from here.

When finish downloading, please modify the corresponding data lists in "./data/" to match your data root.

Training DOT for Unsupervised Domain Adaptation

Source Model

First, download the ImageNet-1k pretrained vit_small and vit_base model, and put them under the "./pretrained/" directory.

Next, a source model is trained to generate initial pseudo-labels for DOT training. The source model can be downloaded here.

Or you can run the following command to train the source model by yourself:

# Office-Home [0,1,2,3]->[Ar,Cl,Pr,Rw]
python train_sourceonly.py --dset home --s 0 --model vit_small --output_src [YOUR_SOURCE_MODEL_ROOT]  --mixup-active --save --seed 2022 --gpu_id 0 

# VisDA2017 [0,1]->[Synthetic,Real]
python train_sourceonly.py --dset home --s 0 --model vit_small --output_src [YOUR_SOURCE_MODEL_ROOT] --mixup-active --save --seed 2022 --gpu_id 0 

Training DOT

Run the following command to train a DOT model.

# Office-Home [0,1,2,3]->[Ar,Cl,Pr,Rw]
python train_DOT.py --dset home --s 0 --t 1 --model dot_small --output_dir output  --src_model_path [YOUR_SOURCE_MODEL_ROOT] --seed 2022 --gpu_id 0

# VisDA2017 [0,1]->[Synthetic,Real]
python train_DOT.py --dset visda2017 --s 0 --t 1 --model dot_small --output_dir output  --src_model_path [YOUR_SOURCE_MODEL_ROOT] iter_per_epoch 1000 --lr 1e-3 --seed 2022 --gpu_id 0
