摘要
通过实例对大坝监测数学模型中存在的欠拟合问题进行了讨论。为解决模型实际应用中的问题 ,笔者引用了积分回归的概念 ,对传统模型的因子集进行了扩充。一般欠拟合的情况下 ,采用该文的处理方法都会使模型效果有明显的改善。
This paper discusses the under fitting problem in mathematical models for dam safety monitoring through case history.To resolve the problem in the application of the models,the author expanded the classical factor set of models by introducing the concept of integral regression.The suggested method can improve the fitting results yielded by the models in the case of under fitting.
