Filter Functions with Exponential Convergence Order
Oversampled functions can be evaluated using generalized sinc-series and filter functions connected with these series. A standard filter function is given by exp((ξ2 − 1)−1). We show that the Fourier transform of this filter posseses the convergence order O(exp(−√x)), improving an estimation given in [10]. Moreover, we define a family of filter functions with convergence order O(x · exp(−xσ)) w...
متن کاملMatrix Functions of Exponential Order
Both the theoretical and practical investigations of various dynamical systems need to extend the definitions of various functions defined on the real axis to the set of matrices. To this end one uses mainly three methods which are based on 1) the Jordan canonical forms, 2) the polynomial interpolation, and 3) the Cauchy integral formula. All these methods give the same result, say g(A), when t...
متن کاملBayesian Optimization with Exponential Convergence
This paper presents a Bayesian optimization method with exponential convergence without the need of auxiliary optimization and without the δ-cover sampling. Most Bayesian optimization methods require auxiliary optimization: an additional non-convex global optimization problem, which can be time-consuming and hard to implement in practice. Also, the existing Bayesian optimization method with exp...
متن کاملAchieving High-Order Convergence Rates with Deforming Basis Functions
This article studies the use of moving, deforming elliptical Gaussian basis functions to compute the evolution of passive scalar quantities in a two-dimensional, incompressible flow field. We compute an evolution equation for the velocity, rotation, extension and deformation of the computational elements as a function of flow quantities. We find that if one uses the physical flow velocity data ...
متن کاملEigenvalue Conditions for Convergence of Singularly Perturbed Matrix Exponential Functions
Abstract. We investigate convergence of sequences of n × n matrix exponential functions t → etA k for t > 0, where Ak → A, Ak is nonsingular and A is nilpotent. Specifically, we address pointwise convergence, almost uniform convergence, and, viewing the exponential as a Schwartz distribution, weak∗ convergence. We show that simple results can be obtained in terms of the eigenvalues of A−1 k alo...
