Data was collected from 50 participants. Coding details are available in user_study_encoding.csv.
The code was written in python2.7. To install the requiements run:
pip install -r requirements.txtExtract the accelerometer data from the recorded walking times.
python get_walking_data.py user_study_encoding.csv raw_data/ walking_data/Extract features from sliding windows.
python extract_windows.py walking_data/ features/Compute classification accuracies of happy vs sad.
python user_lift.py -mo features/features_mo_ew* -mu features/features_mu_ew* -mw features/features_mw_ew* -o acc_f1Compute classification accuracies of happy vs sad vs neutral.
python2 user_lift.py -mo features/features_mo_ew* -mu features/features_mu_ew* -mw features/features_mw_ew* -o neutral --neutralRun permutation test to determine if accuracies are higher than baseline.
