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 tradeoff between the training error and margin. The "onevs.rest" method was used for solving multiclass problems. The parenthesized values are the pvalues. The values in bold font have a statistically significant difference from the base value. A difference is labeled statistically significant when the pvalue is less than 0.05 on the Wilcoxon signedranks sum test (twosided).
