Abstract :
Discusses the activation and deactivation phenomenon in a backpropagation network. The failure of an excitatory network to distinguish certain input patterns is explained by using the `IT´ example. In a character recognition problem, the characters `I´ and `T´ have a very special characteristic; the letter `I´ is embodied in the letter `T´. The partial inhibitory network is introduced; it can perform feature deactivation and multiple object recognition, and is applicable to this type of problem. The deductive factor governs the inhibitory effect in the network. A small deductive factor increases the performance in multiple object recognition, but also increases the training time
