Official Implementation for ProxyMix

ProxyMix: Proxy-based Mixup Training with Label Refinery for Source-Free Domain Adaptation

This implementation is based on ATDOC.

Framework:

1. train on the source domain;
2. Construct the proxy source domain and train on target dataset.

Prerequisites:

• python == 3.6.8
• pytorch ==1.1.0
• torchvision == 0.3.0
• numpy, scipy, sklearn, PIL, argparse, tqdm

Dataset:

• Please manually download the datasets Office, Office-Home, VisDA-C from the official websites, and modify the path of images in each '.txt' under the folder './data/'. [**How to generate such txt files could be found in https://github.com/tim-learn/Generate_list **]

Training:

1. Office-31 dataset

   # train source model
   python train_source.py --dset office --s 0 --max_epoch 50
   # train target model
   python train_target.py --dset office --easynum 5 --output test --gpu_id 7 --s 0 --t 1
   python train_target.py --dset office --easynum 5 --output test --gpu_id 7 --s 0 --t 2
   

2. Office-Home dataset

   • Coming soon ...

3. VISDA-C dataset

   • Coming soon ...
