Table 1.

Intra-subject comparison of Kappa associated with NoPert and Pert, and the relative Z-score.

a. Unsupervised feature extraction				b. Supervised feature extraction
Sbj	K(NoPert)	K(Pert)	Z-score	Sbj	K(NoPert)	K(Pert)	Z-score
S1	0.95	0.81	1.47	S1	0.97	0.85	1.23
S2	0.85	0.75	1.24	S2	0.79	0.67	1.47
S3	0.59	0.58	0.02	S3	0.58	0.48	1.16
S4	0.79	0.64	1.75	S4	0.63	0.67	0.42
S5	0.68	0.75	0.90	S5	0.76	0.76	0.02

Two conditions are significantly different (α = 0.05) if Z-score is >1.96. The table shows the results of the Unsupervised and Supervised feature extraction-based decoders. To note that chance level is K = 0.
