Performance comparison between the best model achieved by MOEA-FW and the baseline. Each plot shows the performance measure by 10-fol cross-validation of the best model achieved by MOEA-FW and the baseline (i.e., all candidate input features) for a particular dataset. The polygon represents a particular performance’s model. When a polygon is covered means that the model is worse in all metrics that the model represented by the polygon that includes it. Wilcoxon signed rank test was performed on the measure resulting from the 10-fold cross-validation of best model achieved by MOEA-FW and the baseline. The models with significant improvement at p-value ≤0.05 are marked with the symbol *
