MemSAC (ECCV 2022)

We present MemSAC (Memory Augmented Sample Consistency for Large-Scale Domain Adaptation) for unsupervised domain adaptation across datasets with many categories or fine-grained classes.

The following dependencies are required.

• Ubuntu 18.04
• Python==3.7.4
• numpy==1.19.2
• PyTorch==1.4.0, torchvision==0.6.0, cudatoolkit==10.1

Data

The datasets can be downloaded using the following links.

1. DomainNet: http://ai.bu.edu/M3SDA/.
2. CUB-Paintings: https://drive.google.com/file/d/1G327KsD93eyGTjMmByuVy9sk4tlEOyK3/view?usp=sharing (from https://github.com/thuml/PAN).

Download the datasets into folder called data/.

Training model on DomainNet

To train the model on DomainNet, run the following script.

bash jobs/domainNet_345.sh <source> <target> <Path for DomainNet dataset> <queue_size>

For example,

bash jobs/domainNet_345.sh real clipart ./data/DomainNet/ 48000

To train the model on CUB-Drawings, run the following script.

bash jobs/cub200.sh <source> <target> <Path for cub2011 dataset> <queue_size>

Testing using trained model.

To directly test our trained model, download the models available at the following links.
