摘要
结合门限自回归模型与人工神经网络模型的建模思想 ,首次提出这两种方法的耦合模型 ,即门限人工神经网络模型。新模型的实质是一种分段非线性化的处理方法 ,是对现有门限模型分段线性化的很好改进。实例计算结果说明 ,新模型在洪水的预报中是有效的 。
According to the modeling concept of the threshold auto-regressive model and artificial neural networks model , a new method called threshold artificial neural networks , is firstly presented in the paper .Compared with the existing threshold model which is linear in each subsection , the essence of the new method is non-linear in each subsection . The result of calculation example shows the flood forecasting with this new method is efficient in flood forecasting and is universal and practical in predicting nonlinear dynamic time series.
