(c) Polynomial

(d) RBF

Figure 11: Comparison with AR and WPT methods (Part (a), (b), (c) and (d) show SVM-based diagnosis experiments with Linear, Quadratic, Polynomial and RBF kernel function, respectively. The -axis indicates Precision (%) of health status or disease/symptom identification, and the explanations of the -axis has already been given in Figure 2.)
