Rapid Approximation Prediction for Kriging
Ziyu Li, Gregory Fasshauer, Douglas Nychka
Exact Kriging and conditional simulation (CS) for uncertainty quantification are computationally infeasible for modern spatial analyses with large numbers of observations and dense…

Anisotropic weights for RBF-PU interpolation with subdomains of variable shapes
R. Cavoretto, A. De Rossi, G. E. Fasshauer +2
The partition of unity (PU) method, performed with local radial basis function (RBF) approximants, has already been proved to be an effective tool for solving interpolation or coll…
