Zusammenfassung
This paper presents a method to design a neural network for coin
recognition by a genetic algorithm (GA). The GA specifies an architecture
of neural network, but does not train the network. The back-propagation
(BP) method trains the network. After training it by the BP, the
GA varies the architecture of the network to fit the environment,
which is to achieve a 100\% recognition accuracy and to make the
network small in size. The network reduced by the GA is further decreased
by using the BP with forgetting of weight. The object of this paper
is to design a smaller neural network for hardware implementation
of coin recognition system. Results by computer simulation show the
effectiveness of the method to variably rotated coin recognition
problem.
