... For bipolar signals the outputs for the two classes are -1 and +1. For unipolar signals it is 0 and 1. Depending on the number of inputs the decision boundary can be a line, plane or a hyperplane. Eg. For two inputs its a line and for three inputs its a plane. If all of the training input vectors fo ...
