Abstract
Disclosed in a pattern recognition apparatus including a neural net including a plurality of mutually coupled excitatory element-inhibitory element paris. The elements in the neural net are coupled through pair coupling coefficients and an excitatory element coupling coefficient. A teacher signal generator outputs a successive teacher signal Q (t) and its infinitesimal variation .DELTA.Q (t) in accordance with a learning pattern, to apply the output teacher signal and the output small variation to a coupling coefficient controller. The coupling coefficient controller carries out a learning processing in accordance with the teacher signal, so that the coupling coefficients in the neural net are updated. An operation time necessary for a pattern recognition is shortened. In addition, since the learning processing is carried out by only a forward processing on time base, a learning time is also decrease.
