Sequential linear regression with online standardized data. [PDF]

PLoS ONE, 2018
The present study addresses the problem of sequential least square multidimensional linear regression, particularly in the case of a data stream, using a stochastic approximation process.

A generalization of Kantorovich operators for convex compact subsets [PDF]

, 2016
In this paper we introduce and study a new sequence of positive linear operators acting on function spaces defined on a convex compact subset. Their construction depends on a given Markov operator, a positive real number and a sequence of probability ...

Effective uniform approximation by the Riemann zeta-function [PDF]

, 2010
We apply an effective multidimensional Ω result of Voronin in order to obtain effective universality-type theorems for the Riemann zeta-function. We further use this approach to study approximation properties of linear combinations of derivatives of the ...

Surrogate methods for determining profiles of material properties of planar test objects with accumulation of apriori information about them [PDF]

Archives of Electrical Engineering
New methods for identifying the material properties of planar objects as a result of measurements by the eddy current method are proposed. The methods are based on the latest surrogate strategies and advanced optimization techniques that improve ...

Finite element approximation of the linear stochastic wave equation with additive noise [PDF]

, 2010
Semidiscrete finite element approximation of the linear stochastic wave equation (LSWE) with additive noise is studied in a semigroup framework. Optimal error estimates for the deterministic problem are obtained under minimal regularity assumptions ...

Single- and Multi-Distribution Dimensionality Reduction Approaches for a Better Data Structure Capturing

IEEE Access, 2020
In recent years, the huge expansion of digital technologies has vastly increased the volume of data to be explored, such that reducing the dimensionality of data is an essential step in data exploration.

Numerical stability analysis of the Euler scheme for BSDEs

, 2014
In this paper, we study the qualitative behaviour of approximation schemes for Backward Stochastic Differential Equations (BSDEs) by introducing a new notion of numerical stability.
