ABSTRACT:
A pattern recognition apparatus includes a pattern input unit inputting pattern data and learning data, and a neural network system including a plurality of neural networks, each of the plurality of neural networks being assigned a corresponding one of a plurality of identification classes and having only two output units of a first unit (Uo1) and a second unit (Uo2). Learning for each of the plurality of neural networks is performed by using the learning data. The image recognition apparatus also includes judgment unit judging which one of the identification classes the pattern data input from the image reading unit belongs to on the basis of output values A and B from the two output units (Uo1) and (Uo2) of all neural networks.
