• Numpy==1.20.1
• scikit-learn==0.24.1

• Wandb=0.12.7 (for sweeps)

Datasets

Available Datasets

We used four public datasets in this study. We also provide the preprocessed versions as follows:

• SSC
• UCIHAR
• MFD

Training procedure

The experiments are organised in a hierarchical way such that:

• Several experiments are collected under one directory assigned by --experiment_description.
• Each experiment could have different trials, each is specified by --run_description.

Training a model

To train a model:

python trainers/train.py  --experiment_description exp1  \
                --run_description run_1 \
                --da_method MAPU \
                --dataset HAR \
                --backbone CNN \
                --num_runs 3 \

Launching a sweep

Sweeps here are deployed on Wandb, which makes it easier for visualization, following the training progress, organizing sweeps, and collecting results.

python trainers/sweep.py  --experiment_description exp1_sweep  \
                --run_description sweep_over_lr \
                --da_method MAPU \
                --dataset HAR \
                --backbone CNN \
                --num_runs 3\
                --num_sweeps 50 \
                --sweep_project_wandb MAPU_HAR

Upon the run, you will find the running progress in the specified project page in wandb.

Results

• Each run will have all the cross-domain scenarios results in the format src_to_trg_run_x, where x is the run_id (you can have multiple runs by assigning --num_runs arg).
• Under each directory, you will find the classification report, a log file, checkpoint, and the different risks scores.
• By the end of the all the runs, you will find the overall average and std results in the run directory.
