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](https://www.hemanthdv.org/officeHomeDataset.html).
### VisDA-2017
VisDA-2017 dataset can be download from [here](http://ai.bu.edu/visda-2017/).
### DomainNet
DomainNet dataset can be download from [here](http://ai.bu.edu/M3SDA/).
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](https://dl.fbaipublicfiles.com/deit/deit_small_distilled_patch16_224-649709d9.pth) and [vit_base](https://dl.fbaipublicfiles.com/deit/deit_base_distilled_patch16_224-df68dfff.pth) 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](https://github.com/BIT-DA/Domain-Oriented-Transformer/releases).
Or you can run the following command to train the source model by yourself:
```python
# 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.
```python
# 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
```
