Application of elman neural network and MATLAB to dam displacement prediction

Based on the fact that the Elman model of neural network tool-box in MATLAB can well approach any nonlinear continuous function and has ability to reflect dynamic features of the systems, a method of dam displacement prediction by Elman model is presented. Through the displacement prediction by Elman model and BP model, the results show that the convergence and accuracy of prediction by the Elman model is higher than that by the BP network model. Taking advantage of network tool-box in MATLAB, Analysts can free themselves from editing hard program and raise working efficiency.
