Suppose there were at least two distinct points P and P ' . Let H be the hyperplane of points equidistant from P and P ' . For W in W , S ( W ) must contain both P and P ' and therefore W must lie in H. We ...

Suppose that patterns are presented to the PWL machine one at a time from a training sequence . Let the initial weight vectors be selected arbitrarily . * We shall describe the adjustments to be made at the kth step .
