Hermite-Birkhoff interpolation on scattered data on the sphere and other manifolds
Giampietro Allasia, Roberto Cavoretto, Alessandra De Rossi
The Hermite-Birkhoff interpolation problem of a function given on arbitrarily distributed points on the sphere and other manifolds is considered. Each proposed interpolant is expre…
Optimal selection of local approximants in RBF-PU interpolation
Roberto Cavoretto, Alessandra De Rossi, Emma Perracchione
The Partition of Unity (PU) method, performed with local Radial Basis Function (RBF) approximants, has been proved to be an effective tool for solving large scattered data interpol…
Positive constrained approximation via RBF-based partition of unity method
Alessandra De Rossi, Emma Perracchione
In this paper, we discuss the problem of constructing Radial Basis In this paper, we discuss the problem of constructing Radial Basis Function (RBF)-based Partition of Unity (PU) i…
