5) Classification using support vector machine (SVM):
With the selected features, the support vector machine
(SVM) method is then used for classification. SVM
optimally separates classes by maximizing the margin
between classes and minimizing the classification error. In
Figure 3, there is clear overlap between the two classes of
PD and control, and among the three classes of PD with
significant gait disturbance, PD with no significant gait
