| 摘 要： | 将集对分析与径向基函数神经网络结合,提出了集对分析径向基函数神经网络预测模型。模型思路是将研究对象t-1时和t时的影响因子集构造为集对并计算联系度,由联系度的同一度、差异度、对立度及研究对象t-1时的值为输入,研究对象t时的值为输出,构建径向基函数神经网络。以年径流预测为例研究表明,模型结构清晰、步骤明确、预测精度较高,为集对分析应用于水文预测提供了新思路。

| Abstract: | The proposed SPA-RBFNN prediction model is a combination of set pair analysis(SPA) and radial basis function neural network(RBFNN).The idea of SPA-RBFNN,firstly sets the impact factors of research object in both t-1 and t period of time as a pair,and calculates the connection degree of the pair,then uses its calculated homology degree,difference degree and antinomy degree,along with the situation of research object in t-1 period of time as model input,the situation of research object in t period of time as ... |
