Confusion matrix – primary grips for residual limb for subjects 1 to 4. The diagonal entries represent the classification accuracy for the different grips. The off-diagonal entries represent inaccurate classifications. (1) For example, for subject 1, open palm grip in the second column is misclassified 10.67% of the time as relaxed hand and 10% of the time as tripod grip. (2) Confusion matrix – primary grips for residual limb for subject 2. (3) Confusion matrix – primary grips for residual limb for subject 3. (4) Confusion matrix – primary grips for residual limb for subject 4.
