Abstract: The defects of the present predicting models of neural networks that didn’t lay enough stress on the new information for working conditions predicting to rotary sets are analyzed, the BP network model is improved and a new predicting model of the weighted new information predicting model of neural network is put forward. The mathematical expression and the topological construction of the new model are presented. The satisfactory results of the on – line predicting are gained.
