Table 22:
Comparison in terms of G-mean and reduction of our memetic algorithm using a decision trees and SVMs and standard decision trees and SVMs. The table shows the win/loss record of each algorithm in the column against the algorithm in the row, the p-value of a two-tailed sign test on the win/loss record, ps, and the p-value of the Wilcoxon test, pw. Significant differences at a confidence level of 95% are marked with a tick (✓).
