TīmeklisHaving read the book myself, this statement refers to a regularized model (edit: I guess all smoothing splines are like that), where every point is a knot, but you are regularizing by adding $\lambda \int g''(x)^2$ to the loss function, so you are punishing a "wiggly function", as expressed in a large absolute second derivative. Tīmeklis2024. gada 6. marts · where the B k are a set of basis functions defining V and β k are the associated spline coefficients. With k knots there are k+1 polynomials of degree d along with d ∗ k constraints, leading to (d+1)(k+1)−d ∗ k=d+k+1 free parameters [9, 41]; for a natural spline there are k free parameters. Since βB=(βA)(A −1 B)=γB ∗ for any …
