New chaotic Elman neural network and its application
Qiang Jin · Journal of Computer Applications · 2009
An improved Elman neural network,the HF Elman network was presented for the modeling of unknown delay and high-order nonlinear system.The stability of the improved Elman network was proved in light of Lyapunov stability theory,and chaos searching was imported to train it,the defect of local extreme of Elman network was eliminated and the learning performance of the new network was improved effectively using global moving characteristic of chaotic mechanism.Simulation results show that the new network and the strategy can improve the network's training speed and the forecast accuracy of ethylene quality index effectively.
