  title={An Invisible Black-Box Backdoor Attack Through Frequency Domain},
  author={Wang, Tong and Yao, Yuan and Xu, Feng and An, Shengwei and Tong, Hanghang and Wang, Ting},
  booktitle={17th European Conference on Computer Vision, ECCV 2022},
  pages={396--413},
  year={2022},
  organization={Springer}
}

basic structure:
1. config args, save_path, fix random seed
2. set the clean train data and clean test data
3. set the attack img transform and label transform
4. set the backdoor attack data and backdoor test data
5. set the device, model, criterion, optimizer, training schedule.
6. save the attack result for defense
