Software requirements

• CUDA
• Python 3.6 or newer
• PyTorch 1.6 or newer
• Other Python libraries listed in requirements.txt

Hardware requirements

• 10 GB available on each GPU
• Optional but strongly recommended: a cluster capable of running at least 8 parallel GPU jobs

Run experiments

To launch an ABAS run (OfficeHome, source Art, target Clipart):

./scripts/launch_slurm_stub.sh \
  --source art-oh \
  --target clipart-oh \
  --criterion 'regression(regressors/regr_no-pseudolabels_for_oh.pkl)' \
  --run-criterion 'regression(regressors/regr_for_oh.pkl)' \
  --net resnet50 \
  --da alda \
  --num-iterations 24 \
  --min-budget 2000 \
  --max-budget 6000 \
  --kill-diverging \
  --data-root /path/to/data

The script launch_slurm_stub.sh needs to be customized according to your cluster setup. A similar script can be developed for other schedulers, like PBS. Once the job is done, a result.pkl file will be produced. To analyze the results, run

./analysis.py --result experiments/your-experiment/results_file.pkl

You can test a specific configuration with

./train_model.py \
    --net resnet50 \
    --da alda \
    --gpu 0 \
    --source art-oh \
    --target clipart-oh \
    --config base.weight_da=0.88,disc.dropout=0.1,disc.hidden_size_log=10,disc.num_fc_layers=5,net.bottleneck_size_log=9 \
    --data-root /path/to/data
