回归样条(regression spline)本质上是一个分段多项式, 但它一般要求每个分段点上连续并且二阶可导,这样可以保证曲线的平滑性。而限制性立方样条是在回归样条的基础上附加要求:样条函数在自变量数据范围两端的两个区间内为线性函数。 在利用限制性立方样条绘制曲线关系时,通常需要设置样条函数节点的个数(k)和位置(ti)。...

In this image, the orange line represents a cubic spline interpolation method, and the blue line represents a linear regression model. We can see the two models oscillate very differently. For the linear regression model, if we are given a data point outside of the boundaries of the training...

A cubic spline regression model was used to fit the experimental open-circuit potential (OCP) curves of two intercalation electrodes of a lithium-ion battery. All the details of an OCP curve were accurately predicted by the resulting model. The number of regression intervals used to fit an OCP...
