Mixed-Norm Regularization for Brain Decoding

Table 1

Performance results on the simulated datasets: the average performance in AUC (in %), the average percent of selected sensors (Sel), and the 𝐹-measure of the selected channels (in %).

Methods	Avg. AUC	AUC 𝑃-val	Avg. Sel	𝐹-measure
SVM	79.79	—	100.00	66.67
GSVM-1	79.32	0.027	98.75	67.25
GSVM-2	80.96	0.004	62.50	89.72
GSVM-p	80.74	0.020	63.12	89.40
GSVM-a	80.51	0.014	45.62	93.98

Best results for each performance measure are in bold.
The 𝑃 value refers to the one of a Wilcoxon signed-rank test with SVM as a baseline.
