Abstract
Method and apparatus of error back-propagation for use in a neural network system. A first group (11) of processing devices (13.sub.1, 13.sub.2, 13.sub.3) performs the resolving steps and a second group (12) of analogous processing devices (13.sub.4, 13.sub.5) performs the training steps while backpropagating errors calculated in a central processing device (10). The synaptic coefficient matrix C.sub.ij of the first group and the transposed matrix T.sub.ji of the second group are simultaneously updated. This updating of the synaptic coefficients can be performed by means of multipliers (34.sub.1 to 34.sub.N) and adders (37.sub.1 to 37.sub.N).
