Figure 5

The graph of classification objects (quadratic) of healthy subjects (red) from patients (green) depending on the features w (1), w (2) and w (3). The graph shows a visual distinction (classification) between healthy subjects and patients. The graph also shows a common area which is included in both data groups (those of patients and healthy subjects). The presented graph is one of the possibilities to create a closed area covering the cases of healthy subjects and patients in the axes of the three features w(1), w(2) and w(3).
