Explicit multivariate approximations from cell-average data

چکیده
Abstract Given gridded cell-average data of a smooth multivariate function, we present constructive explicit procedure for generating high-order global approximation the function. One contribution is derivation approximations to point-values function directly from data. The second development univariate B-spline-based quasi-interpolation operators using Multivariate spline are obtained by tensor product operators.

Approximate approximations from scattered data
The aim of this paper is to extend the approximate quasi-interpolation on a uniform grid by dilated shifts of a smooth and rapidly decaying function on a uniform grid to scattered data quasi-interpolation. It is shown that high order approximation of smooth functions up to some prescribed accuracy is possible, if the basis functions, which are centered at the scattered nodes, are multiplied by ...
متن کاملNetwork inference from single-cell data using multivariate information measures
G ene expression is robustly controlled in space and time by networks of transcriptional regulators. Single cell data now allow us to probe and map these networks and cellular transcriptional states in unprecedented detail, but the heterogeneity and large sample sizes that characterise these data pose new analytical challenges. Here we develop an algorithm that exploits these features to infer ...
متن کاملExponential Approximation of Multivariate Bandlimited Functions from Average Oversampling
Instead of sampling a function at a single point, average sampling takes the weighted sum of function values around the point. Such a sampling strategy is more practical and more stable. In this note, we present an explicit method with an exponentially-decaying approximation error to reconstruct a multivariate bandlimited function from its finite average oversampling data. The key problem in ou...
متن کاملMoving - Average Representation of Autoregressive Approximations
We study the properties of an MA1-representation of an autoregressive a p p r o x-imation for a stationary, real-valued process. In doing so we g i v e an extension of Wiener's Theorem in the deterministic approximation setup. When dealing with data, we can use this new key result to obtain insight i n to the structure of MA1-representations of tted autoregressive models where the order increas...
متن کاملDiscretized Approximations for POMDP with Average Cost
In this paper, we propose a new lower approximation scheme for POMDP with discounted and average cost criterion. The approximating functions are determined by their values at a finite number of belief points, and can be computed efficiently using value iteration algorithms for finite-state MDP. While for discounted problems several lower approximation schemes have been proposed earlier, ours se...
