Damage Detection of Structures for Ambient Loading Based on Cross Correlation Function Amplitude and SVM

Figure 7

CV accuracy with and for polynomial, RBF, and SKF kernel functions, in the second loading condition.

(a) Polynomial kernel function (). Optimal and are C = , = 2¹⁰

(b) RBF kernel function. Optimal and are C = , = 2⁸

(c) SKF kernel function. Optimal and are C = 2⁶, = 2²
