Thin-plate spline

Thin plate splines (TPS) are a spline-based technique for data interpolation and smoothing. They were introduced to geometric design by Duchon. They are an important special case of a polyharmonic spline. Robust Point Matching (RPM) is a common extension and shortly known as the TPS-RPM algorithm. See more The name thin plate spline refers to a physical analogy involving the bending of a thin sheet of metal. Just as the metal has rigidity, the TPS fit resists bending also, implying a penalty involving the smoothness of the … See more • Elastic map (a discrete version of the thin plate approximation for manifold learning) • Inverse distance weighting • Polyharmonic spline (the thin plate spline is a special case of a … See more The thin plate spline has a natural representation in terms of radial basis functions.

WebFeb 1, 2024 · One can also fit a thin plate spline to the same data by: p=1; st=tpaps ( [xData',yData'],zData',p) The resulting structure, st, includes st.coefs, which is a vector of 12 coefficients. By setting p=1, tpaps () returns an exact-fitting thin plate spline. As p decreases toward 0, the fit becomes increasingly approximate. WebApr 18, 2024 · Thin plate splines are therefore smoothing splines with a knot at each covariate value. To then obtain a low rank smoother Wood does an eigendecomposition and picks the first k eigenvectors which contains most of the variance. My question is why it is useful to build low rank smoothers? To reduce computational cost?
