چکیده

In this paper, investigate the approximation of unbounded functions in weighted space, by using trigonometric polynomials considered. We introduced type piecewise monotone having same local monotonicity as without affecting order huge error have a finite number max. and min. that amount. addition, we established not included any extreme points functions, closed subset γ on intervals then there exist class such best has high or for sufficiently great at each γ.

Space Efficient Approximation of Piecewise Linear Functions

In this work, we compute upper bounds of piecewise linear functions which is a special case of piecewise linear approximation. There are several application areas like pattern recognition or cartography. The goal is to reduce the number of sampling points while still preserving the characteristics of given data. The problem of approximating a given piecewise linear function with n sampling poin...

On 3-monotone approximation by piecewise polynomials

Abstract. We consider 3-monotone approximation by piecewise polynomials with prescribed knots. A general theorem is proved, which reduces the problem of 3-monotone uniform approximation of a 3-monotone function, to convex local L1 approximation of the derivative of the function. As the corollary we obtain Jackson-type estimates on the degree of 3-monotone approximation by piecewise polynomials ...

A Piecewise Constant Algorithm for Weighted L1 Approximation over Bounded or Unbounded Regions in R

Using Smolyak’s construction [5], we derive a new algorithm for approximating multivariate functions over bounded or unbounded regions in R with the error measured in a weighted L1-norm. We provide upper bounds for the algorithm’s cost and error for a class of functions whose mixed first order partial derivatives are bounded in L1-norm. In particular, we prove that the error and the cost (measu...

Monotone circuits for monotone weighted threshold functions

Weighted threshold functions with positive weights are a natural generalization of unweighted threshold functions. These functions are clearly monotone. However, the naive way of computing them is adding the weights of the satisfied variables and checking if the sum is greater than the threshold; this algorithm is inherently non-monotone since addition is a non-monotone function. In this work w...

Approximation and Compression of Piecewise Smooth Functions

Wavelet or subband coding has been quite successful in compression applications, and this success can be attributed in part to the good approximation properties of wavelets. In this paper, we revisit rate-distortion bounds for wavelet approximation of piecewise smooth functions, in particular the piecewise polynomial case. We contrast these results with rate-distortion bounds achievable using a...
