| 摘 要： | 对RBF神经网络进行了分析,建立了RBF神经网络模型,并对此模型进行了改进,使其具有更好的预测性能.把一类非线性较强的时间序列(万科A股2009年6月份股票价格)利用该模型进行了非线性逼近.用Matlab软件对网络的学习与训练过程进行了数值仿真.实验结果表明:利用改进后的网络模型对非线性时间序列进行短期预测是可行的,其预测精度高于改进前的预测精度,改进方法有效.

| Abstract: | RBF neural network is analyzed in this paper,and RBF neural network model is established,too.The model is improved to have better prediction performance.A strong class of nonlinear time series(stock price of Wanke A in June of 2009)is approached by using the model.Matlab software is applied to carry out numerical simulation of the network's learning and training process.Simulation results show that the improved network model for short-term prediction of nonlinear the series is feasible,and its prediction ac... |
