The tuned parameters (gamma, coef0, cost) and the performance estimates (sensitivity, specificity, accuracy) for each iteration are shown. The parameters corresponding to the best performance are shaded. A p-value from McNemar's Chi-square test was computed, and p < 0.05 was considered statistically significant.
