TABLE 4:

The balanced accuracy (BAcc) of the proposed classifier and the baseline methods on the three neuroimaging datasets.

	SFSH	SFSP	SFSC	${\mathbf{JFSS}}_{{\mathit{\ell }}_{\mathbf{1}}}$-W	${\mathbf{JFSS}}_{{\mathit{\ell }}_{\mathbf{1}}}$ [53]	$\mathbf{L}{\mathbf{R}}_{{\mathit{\ell }}_{\mathbf{0}}}$-W [62]	FSSVM-W	SVM-W	SVM
CTRL vs. ALC	69.2	67.7	67.3	65.1	62.9	67.7	66.7	64.0	59.4†
CTRL vs. HIV	75.1	74.5	74.0	70.1	53.6	67.9	68.4	62.8†	52.4†
CTRL vs. ALC+HIV	77.9	76.5	77.0	71.5	55.4†	71.6	69.7	65.2	54.3†

Scores with ^† are not significantly better than chance, i.e.,, p-value > 0.001 according to the Fisher exact test [79].
