Generalized MLS and LS-SVR for Allen-Cahn Equations on Spheres
Vahid Mohammadi, Mehdi Dehghan, Stefano De Marchi
This work extends least-squares support vector regression (LS-SVR) based on the generalized moving least squares (GMLS) approximation to the numerical solution of partial different…
Mapping for Approximation: A Unified View of Rescaled, Variably Scaled and Rational Kernel Methods
Stefano De Marchi
Classical approximation methods are usually improved by changing the sampling set, increasing the number of data points, or selecting a different basis. We advocate a complementary…
Results, challenges and new steps on RBF approximation and computation
Stefano De Marchi, Nadaniela Egidi, Josephin Giacomini +1
We present an up-to-date overview of approximation methods based on Radial Basis Function (RBF) techniques, which have recently attracted attention across various computational too…
Geometric properties of the Lebesgue function
Leokadia Białas-Cież, Stefano De Marchi, Mateusz Suder
We present a collection of observations concerning the peculiar behavior of the Lebesgue function in the setting of the interval and the square $[-1,1]^2…
