5.3 The Perceptron Concept   163



























                              Figure 5.15.  Separation of  U's  (right side) from V's  (left side) by  a perceptron.
                              Borderline U and V lying near the linear discriminant are also shown.



























                               Figure 5.16. Non-separable situation  of  U's and V's.  One of  the perceptron's  best
                               solutions is shown.



                                 We  will illustrate this behaviour  using the Perceptron program included  in the
                               CD (see Appendix B). This program demonstrates  the perceptron learning rule for
                               a two-class problem consisting of the discrimination  of  handwritten  U's  and V's.
