Abstract: | An algorithm of approximation of a multidimensional point-by-point scalar function is considered. The solution is sought as
a series in a set of basis functions. The approximation is regularized by the introduction of a stabilizing function in the
Gaussian form; the parameter of regularization is sought by using the Bayesian approach. The proposed algorithm is inexpensive
in terms of computations. Unlike other Bayesian models of approximation, it has a unique analytical solution for the regularization
parameters. |
