Stacked bar graph of the F1-scores for the k-NN and SVM classifiers for all the classes and participants. The participants rank ordered based on the total value of the F1-score in the presented classes. The black horizontal line represents a general cutoff for the highly functional levels of classification performance (average F1-score > 0.95). a) Stacked bar graph of F1-scores from the k-NN classifier. b) Stacked bar graph of F1-scores from the SVM classifier. NC = Noncompensation, TLF = Trunk lean-forward, TR = Trunk rotation, SE = Shoulder elevation, k-NN = k-nearest neighbor, SVM = support vector machine
