In FIG. 4, for convenience of explanation, a configuration having three inputs and three outputs is shown. When a plurality of inputs are input to the input layer (X1-X3), the value is multiplied by the weight W1 (w11-w16) and input to the intermediate layer (Y1-Y2), and the result is further weighted W2 (w21-). It is output from the output layer (Z1-Z3) by multiplying it by w26). This output result depends on the values of the weights W1 and W2. In the first embodiment, the data input to the input layer is X1 to X9, and the data output from the output layer is Z.
