Our discriminant- function pattern classifier , illustrated in Fig . 1.4 , would employ R dis- criminators , each of which computes the value of a discriminant function . The outputs of the discriminators will be called discriminants .

The performance level which the pattern classifier is eventually to achieve must be achieved largely by an adjustment process , which has become known as training . The training process proceeds as follows : a large number of patterns ...
