Figure 5

The decision surfaces of the multiclass SVMs in classifying the five classes (four gaze and one resting-state (non-gaze) conditions) in subject 1 and 6. The solid lines are the decision boundaries to separate each class from others. Colors code the outputs of decision function of the trained multiclass SVM.
