A HIGHLY RELIABLE RECONSTRUCTION OF A BP NETWORK WHEN INPUT ERRORS CONSIDERED
Zhiwen Yao · Acta Automatica Sinica · 1992
The input errors of BP(Back-Propagation) network are classified into dead point error and phase reversal error in this paper. A highly reliable reconstruction method for a BP network is proposed. The reliability problem of the reconstructed BP network is discussed under the above mentioned input errors respectively. It is shown that, when the probabilities that the inputs are correct (input reliabilities) are varying within a determined region, by increasing the number of inputs, the probability that the reconstructed BP network realizes the giyen function correctly (network reliability) may approach 1. The reconstructed BP network is fault tolerant to input errors to some extent.
