Confusion matrix showing an overlay for all three subjects for the DTW approach using data from the best test run for each subject. As with the Affinity approach, most predictions are close to the diagonal (dark cells), and many incorrect classifications are clustered around common activity groups (tip pinch, 3-jaw chuck, etc.). Similar to the Affinity approach is the confusion between the tip pinch group (TPx) and neutral/rest (NR)
