Figure 5. Wilcoxon signed-rank test p-values that show significant differences (i.e., from 0 to 0.05) between control and non-control SampEn features in the optimization dataset. Hyperparameters were fixed to their optimal values. Note that p-values were adjusted using the Benjamini–Hochberg False Discovery Rate (FDR) step-up procedure.
