多元非线性回归——岭回归方法,比常规的最小二乘更适合数据量较大的优化问题(Multiple nonlinear regression- ridge regression method is more suitable than the conventional least squares optimization problem of the large amount of data)
对大量数据的差值与拟合算法的Matlab实现,基于多用思想(The difference of large amounts of data fitting algorithm of the Matlab implementation, based on multi-thinking)
支持向量机和BP神经网络都可以用来做非线性回归拟合,但它们的原理是不相同的,支持向量机基于结构风险最小化理论,普遍认为其泛化能力要比神经网络的强。大量仿真证实,支持向量机的泛化能力强于BP网络,而且能避免神经网络的固有缺陷——训练结果不稳定。本源码可以用于线性回归、非线性回归、非线性函数拟合、数据建模、预测、分类等多种应用场合(Support vector machines and BP neural network can be used for non-linear regression fit, but they is not the same principle, support vector machine based on structural risk minimization theory, generally considered its generalization ability than the neural network of strong . Inherent defect- a large number of simulation confirmed that generalization ability of support vector machine is stronger than the BP network, but also to avoid neural network training results unstable. The source code can be used for linear regression, nonlinear regression, nonlinear function fitting a variety of applications, data modeling, forecasting, classification)
克里金(Kriging)插值法又称空间自协方差最佳插值法,它是以南非矿业工程师D.G.Krige的名字命名的一种最优内插法。克里金法广泛地应用于地下水模拟、土壤制图等领域,是一种很有用的地质统计格网化方法。它首先考虑的是空间属性在空间位置上的变异分布.(Kringing smooth)
