Spline (mathematics) - Wikipedia
网页In mathematics, a spline is a function defined piecewise by polynomials. In interpolating problems, spline interpolation is often preferred to polynomial interpolation because it yields similar results, even when using low degree polynomials, while avoiding Runge's phenomenon for higher degrees.
一文读懂回归样条（regression splines），附Python代码 - 知乎

网页在数学学科数值分析中，样条（spline）是一种特殊的函数，由多项式分段定义。 样条的 英语 单词 spline 来源于可变形的样条工具，那是一种在 造船 和 工程制图 时用来画出光滑形状的工具。
Curves & Splines 写一点 - 知乎 - 知乎专栏
网页样条(Spline) 可以理解为 多段 Cubic Curve 的拼接，不过样条在 Cubic Curve 拼接的时候，提出了特殊要求：两段 Cubic Curve 在拼接的位置，需要能够“平滑衔接”，以保证整个样条的曲线平滑。

Regression splines — Introduction to Regression Models
网页To learn more about the spline regression method, review “An Introduction to Statistical Learning” from [James et al., 2021]. Regression splines involve dividing the range of a feature X into K distinct regions (by using so called knots). Within each region, a polynomial function (also called a Basis Spline or B-splines) is fit to the data.
Smoothing splines — SciPy v1.14.1 Manual
网页Spline interpolation requires two essential steps: (1) a spline representation of the curve is computed, and (2) the spline is evaluated at the desired points. In order to find the spline representation, there are two different ways to represent a curve and obtain (smoothing) spline coefficients: directly and parametrically.
A Very Gentle Introduction to Splines - GitHub Pages
网页1 Linear Splines. 1.1 Mathematical model. Instead of a single regression line, we fit a set of piecewise linear regressions with the only restriction being that they intersect at the knots. Mathematically, with one predictor variable, we write the regression equation as follows. Note that we have K + 2 parameters to estimate.
Spline -- from Wolfram MathWorld
网页2024年8月22日 · Spline. A piecewise polynomial function that can have a locally very simple form, yet at the same time be globally flexible and smooth. Splines are very useful for modeling arbitrary functions, and are used extensively in computer graphics.
