ABSTRACT:
A neural network computation apparatus having a plurality of layers, each of the plurality of layers has at least an input layer and an output layer, each layer having a plurality of units, a plurality of links, each of the plurality of links connecting units on the plurality of layers, and changing means for changing input and output characteristics of a particular unit of the plurality of units and/or the weight of a particular link of the plurality of links in accordance with an output of the output layer after learning an example and with a particular rule. After the neural network computation apparatus learns an example, the changing means changes input and output characteristics of units and weights of links in accordance with outputs of the output layer and a particular rule. Thus, a mutual operation between a logical knowledge and a pattern recognizing performance can be accomplished and thereby a determination close to that of a specialist can be accomplished. In other words, a proper determination in accordance with an experience can be made so as to deal with unknown patterns with high flexibility.
