Confusion matrix showing an overlay for all three subjects for the Affinity approach using data from the best Approach 2 test run for each subject. Darker cells indicate higher numbers of correct predictions, which can be seen along the diagonal. Most cells are white, indicating zero predictions. Note that most predictions are close to the diagonal, and many incorrect classifications are clustered around common activity groups (tip pinch, 3-jaw chuck, etc.). A notable exception is the confusion between the tip pinch group (TPx) and neutral/rest (NR)
