Multi-class Classification

Multi-class Classification. Mu-Chun Su. Case I. Each pattern class is separable from the other classes by a single hyperplane. M classes need M Perceptrons. A decision can not be made if (1) more than one perceptron have positive outputs; (2) none of the perceptron has positiveb output.
