PyTorch Implementation for CAiDA

[NeurIPS-2021] Confident Anchor-Induced Multi-Source Free Domain Adaptation

This is the implementation code of our paper "Confident Anchor-Induced Multi-Source Free Domain Adaptation" accepted by NeurIPS-2021.

Overview of The CAiDA Model

Requirements:

• python == 3.6.8
• pytorch == 1.1.0
• numpy == 1.17.4
• torchvision == 0.3.0
• scipy == 1.3.1
• sklearn == 0.5.0
• argparse, PIL

Datasets Preparation:

• Office Dataset: Download the datasets Office-31, Office-Home, Office-Caltech from the official websites.
• Digits-Five Dataset: Download the datasets MNIST, MNIST-M, USPS, SVHN, Synthetic Digits from the official websites.
• DomainNet Dataset: Download DomainNet from the official website.
• Place these datasets in './data'.
• Using gen_list.py to generate '.txt' file for each dataset (change dataset argument in the file accordingly).

Training:

• Train source models (shown here for Office with source A)

python train_source.py --dset office-31 --s 0 --max_epoch 100 --trte val --gpu_id 0 --output ckps/source/

• Adapt to target domain (shown here for Office with target D)

python train_target_CAiDA.py --dset office-31 --t 1 --max_epoch 15 --gpu_id 0 --cls_par 0.7 --crc_par 0.01 --output_src ckps/source/ --output ckps/CAiDA
