The official PyTorch implementation of the CVPR 2022, L3D-IVU Workshop paper titled "Attention Consistency on Visual Corruptions for Single-Source Domain Generalization". This repository contains: (1) our single-source domain generalization benchmark that aims at generalizing from natural images to other domains such as paintings, cliparts and skethces, (2) our adaptation/version of well-known advanced data augmentation techniques in the literaure, and (3) our final model ACVC which fuses visual corruptions with an attention consistency loss.

Dependencies

torch~=1.5.1+cu101
numpy~=1.19.5
torchvision~=0.6.1+cu101
Pillow~=8.3.1
matplotlib~=3.1.1
sklearn~=0.0
scikit-learn~=0.24.1
scipy~=1.6.1
imagecorruptions~=1.1.2
tqdm~=4.58.0
pycocotools~=2.0.0

• We also include a YAML script acvc-pytorch.yml that is prepared for an easy Anaconda environment setup.

• One can also use the requirements.txt if one knows one's craft.

Training

Training is done via run.py. To get the up-to-date list of commands:

python run.py --help

We include a sample script run_experiments.sh for a quick start.

Analysis

The benchmark results are prepared by analysis/GeneralizationExpProcessor.py, which outputs LaTeX tables of the cumulative results in a .tex file.

• For example:

python GeneralizationExpProcessor.py --path generalization.json --to_dir ./results --image_format pdf

• You can also run distributed experiments, and merge the results later on:

python GeneralizationExpProcessor.py --merge_logs generalization_gpu0.json generalization_gpu1.json

Case Study: COCO benchmark

COCO benchmark is especially useful for further studies on ACVC since it includes segmentation masks per image.

Here are the steps to make it work:

1. For this benchmark you only need 10 classes:

airplane
bicycle
bus
car
horse
knife
motorcycle
skateboard
train
truck

2. Download COCO 2017 trainset, valset, and annotations

3. Extract the annotations zip file into a folder named COCO inside your choice of data_dir (For example: datasets/COCO)

4. Extract train and val set zip files into a subfolder named downloads (For example: datasets/COCO/downloads)

5. Download DomainNet (clean version)

6. Create a new DomainNet folder next to your COCO folder

7. Extract each domain's zip file under its respective subfolder (For example: datasets/DomainNet/clipart)

8. Back to the project, use --first_run argument once while running the training script:

python run.py --loss CrossEntropy --epochs 1 --corruption_mode None --data_dir datasets --first_run --train_dataset COCO --test_datasets DomainNet:Real --print_config

9. If everything works fine, you will see train2017 and val2017 folders under COCO

10. Both folders must contain 10 subfolders that belong to shared classes between COCO and DomainNet

11. Now, try running ACVC as well:

python run.py --loss CrossEntropy AttentionConsistency --epochs 1 --corruption_mode acvc --data_dir datasets --train_dataset COCO --test_datasets DomainNet:Real --print_config

12. All good? Then, you are good to go with the COCO section of run_experiments.sh to run multiple experiments

13. That's it!
