High order approximation to non-smooth multivariate functions
Approximations of non-smooth multivariate functions return low-order approximations in the vicinities of the singularities. Most prior works solve this problem for univariate functions. In this work we introduce a method for approximating non-smooth multivariate functions of the form f = g + r+ where g, r ∈ C(R) and the function r+ is defined by r+(y) = { r(y), r(y) ≥ 0 0, r(y) < 0 , ∀y ∈ R . G...
متن کاملOptimal Order of Convergence and (In-) Tractability of Multivariate Approximation of Smooth Functions
We study the approximation problem for C∞ functions f : [0, 1] → R with respect to a Wm p -norm. The optimal order of convergence is infinite, hence excellent, but the problem is still intractable for m ≥ 1. This means that the order of convergence supplies incomplete information concerning the computational difficulty of a problem. For m = 0 and p = 2, we prove that the problem is not polynomi...
متن کاملApproximation of Multivariate Functions
We discuss one approach to the problem of approximating functions of many variables which is truly multivariate in character. This approach is based on superpositions of functions with infinite families of smooth simple functions. §
متن کاملApproximation of Multivariate Functions
| In this paper, a new class of higher-order feedforward neural networks, called ridge polynomial networks (RPN) is formulated. The new networks are shown to uniformly approximate any continuous function on a compact set in multidimensional input space with any degree of accuracy. Moreover, these networks have an eecient and regular architecture as compared to ordinary higher-order feedforward ...
متن کاملMultivariate Refinable Functions of High Approximation Order Via Quotient Ideals of Laurent Polynomials
We give an algebraic interpretation of the well–known “zero–condition” or “sum rule” for multivariate refinable functions with respect to an arbitrary scaling matrix. The main result is a characterization of these properties in terms of containment in a quotient ideal, however not in the ring of polynomials but in the ring of Laurent polynomials.
