混凝土的抗压强度随养护时间的延长而增加，现将一批混凝土作成12个试块，记录了养护日期x（日）及抗压强度y（kg/cm2）的数据：求型回归方程 示例方程在内(The compressive strength of concrete with curing time and increase the extension, now make a number of concrete block 12, recording the date of the conservation of x (day) and compressive strength of y (kg/cm2) of data: the regression equation for sample-based equation, including)

径向基函数是一个取值仅仅依赖于离原点距离的实值函数，也就是Φ（x）=Φ(‖x‖),或者还可以是到任意一点c的距离，c点称为中心点，也就是 Φ（x，c）=Φ(‖x-c‖)。任意一个满足Φ（x）=Φ(‖x‖)特性的函数Φ都叫做径向量函数，标准的一般使用欧氏距离，尽管其他距离函数也是可以的。一些径向函数代表性的用到近似给定的函数，这种近似可以被解释成一个简单的神经网络，径向基函数在支持向量机中也被用做核函数。(Radial basis function depends only on the value of a real-valued function of the distance from the origin, i.e. Φ (x) = Φ (x ‖ ‖) or may also be the distance to any point c, c is called the center point , i.e. Φ (x, c) = Φ (xc ‖ ‖). Satisfy any one of Φ (x) = Φ (x ‖ ‖) characteristic functions are called radial vector function Φ standard Euclidean distance is generally used, although other distance functions are also possible. Some typical uses radial function approximation given function, this approximation can be interpreted as a simple neural network, RBF in support vector machines have also been used to make nuclear functions.)
