Refined Error Estimates for Radial Basis Function Interpolation Academic Article uri icon


  • We discuss new and refined error estimates for radial-function scattered data interpolants and their derivatives. These estimates hold on Rd, the d-torus, and the 2-sphere. We employ a new technique, involving norming sets, that enables us to obtain error estimates, which in many cases give bounds orders of magnitude smaller than those previously known.
