Table 7 Effects of tuning parameters on system performance. The "base" parameters are shown in Table 4. The "deg." means the degree of the polynomial kernel, the "win." is the window range, and "cv" is the cost of constraint violation. The cost is the trade-off between the training error and margin. The "one-vs.-rest" method was used for solving multi-class problems. The parenthesized values are the p-values. The values in bold font have a statistically significant difference from the base value. A difference is labeled statistically significant when the p-value is less than 0.05 on the Wilcoxon signed-ranks sum test (two-sided).
