As a result, for feed-forward NN model this paper first proposes the concepts of"attractor"and"attraction region","fake attractor"and"fake attraction region", and norm of describing"attraction region". Further this paper presents a mathematics method of calculating feed-forward NN"attraction region", it solves the overelaborate job of checking NN fault-tolerance performance by testing all detecting samples, so to test fault-tolerance performance using theoretic characteristic norm is an important break. In accordance with feed-forward NN low fault-tolerance and difficult to satisfy practical application, according to practical application theory, this paper presents an actual method of enhancing NN fault-tolerance performance, builds the mechanism of reconstructing NN model based on combining NN and fuzzy process, reforms NN "fake attractor"and"fake attraction region"to enhance NN fault-tolerance performance greatly.
