Table 2 The number of selected voxels in Stage I of FIDF

From: Brain response pattern identification of fMRI data using a particle swarm optimization-based approach

Stage I	SFS		SBS		PSO–SVM		HHPSO–SVM
Stage I	Mean	SD	Mean	SD	Mean	SD	Mean	SD
1	39	5	577	0	84	24	116	22
2	30	5	464	0	60	15	84	15
3	32	5	306	1	55	17	88	16
4	31	5	675	0	68	21	100	20
5	30	5	420	0	38	13	54	13
6	34	4	348	1	55	16	82	14

Average number and standard deviation of selected voxels are calculated for WFS without feature selection, SFS sequential forward feature selection, SBS sequential backward feature selection, PSO–SVM and HHPSO–SVM
