Spline (mathematics) - Wikipedia
WEBIn 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.

WEBOct 5, 2023 · Interpolating Cubic Spline. Given n+1 data points, (x_0,y_0),\ (x_1,y_1),\ldots,\ (x_n,y_n), fit an interpolating cubic spline through the data. For cubic spline interpolation, piecewise cubic polynomials approximate the data between two consecutive points. The interpolating cubic spline is given by the cubics as.
WEBFinally, I will assert that smoothing splines are linear smoothers, in the sense given in earlier lectures: predicted values are always linear combinations of the original response values y i. 1.1 The Meaning of the Splines Look back to the optimization problem. As !1, having any curvature at

Cornell CS4620 Fall 2020 Steve Marschner •. • In many applications we need smooth shapes. – that is, without discontinuities. • So far we can make. – things with corners (lines, triangles, squares, rectangles, …) – circles, ellipses, other special shapes (only get you so far!)

WEB1.2.2 Penalization: Restrict the \ (b_i\) coefficient magnitudes. This is an alternative to choosing knot location. Assume a large-ish number of knots is OK, then control overfitting via penalization. We use a penalty term \ (\lambda\) to constrain coefficients as follows.
