WebA Simple Linear GAM Model Built Using Smoothers from Multiple Predictors Thin plate splines are used to estimate smooth functions of multiple predictor variables from noisy observations of the function at particular values of those predictors. Consider: Yi = g(xi) + ϵi where: xiϵRd, d is the number of predictors in the smooth function g.

WebOct 31, 1996 · Thin-plate spline approximation for image registration Abstract: The point-based registration technique of F.L. Bookstein (1989) can be seen as an interpolation problem. With this technique an elastic transformation based on thin-plate splines is determined which maps the source and target landmarks exactly to each other. WebIn ndimensions, the idea of thin-plate splines is to choose a function f(x) that exactly interpolates the data points (x i;y i), say, y i = f(x i), and that minimizes the bending energy, E[f] = Z Rn jD2fj2 dX (1) where D2f is the matrix of second-order partial derivatives of f and jD2fj2 is the sum of squares of the matrix entries.
