4.5 An error - correction training procedure for R > 2 = A linear machine for classifying patterns belonging to more than two categories was defined in Chapter 2. It consists of R linear discriminators and a maximum selector ( Fig .

fortunately , no efficient training procedures are known which simultaneously locate the weight vectors and adjust their voting strengths . Therefore , our discussion will concentrate on the " simple - majority ” committee machine with ...

Suppose that we decided to use an error - correction training procedure to train a single TLU . Even though a TLU is capable of implementing the optimum decision surface , an error - correction procedure could never stabilize at the ...
