Installation

1. We provide the yml-file for the virtual conda envirement in the file
   pytorch.yml. After installation you should be able to run the code in this repository.

2. First, download the dataset your are prefering. The links to the datasets can be found in the respective sections.

3. After download, unzip the files and place the output folders as they are in the directory images.

4. (Optional: Adapt the dataset lists in data to your to preferred path)

Demo

For a simple training-evaluation demo run with preset parameters, you can use the following commands for training on

Office-31 A->W
train_image.py --tl RSL --s_dset_path data/office/amazon.txt --t_dset_path data/office/webcam.txt --test_interval 100 --num_workers 12 --sn True --k 11 --tllr 0.001

Image-Clef I->P
train_image.py --tl RSL --dset image-clef --s_dset_path data/office/amazon.txt --t_dset_path data/office/webcam.txt --test_interval 100 --num_workers 12 --sn True --k 11 --tllr 0.001

Training and Inference

1. The network can be trained via train_image.py See the Args-Parser parameter description in the file for the documentation of the parameters.

2. The trained models are obtainable under snapshopt/san
