The Gaussian process (GP) regression can be severely biased when the data are contaminated by outliers. This paper presents a new robust GP algorithm that iteratively trims most extreme points. While retains attractive properties of standard as nonparametric and flexible method, it greatly improve model accuracy for even in presence or abundant It is also easier to implement compared with previ...

this paper deals with scrutinizing the convergence properties of iterative methods to solve linear system of equations. recently, several types of the preconditioners have been applied for ameliorating the rate of convergence of the accelerated overrelaxation (aor) method. in this paper, we study the applicability of a general class of the preconditioned iterative methods under certain conditio...

In this paper, we introduce an iterative process for approximating common fixed points of two finite families of nonexpansive mappings in Banach spaces. Our process contains some iterative processes being used for the purpose. We prove some weak and strong convergence theorems for this iterative process. Our results generalize and improve some results in contemporary literature.

This paper presents an efficient method for updating the structural finite element model. Model updating is performed through minimizing the difference of recorded acceleration of real damaged structure and hypothetical damaged structure, by updating physical parameters in each phase using iterative process of Levenberg-Marquardt algorithm. This algorithm is based on sensitivity analysis and pr...

In this paper, we prove strong convergence results for a modified Mann iterative process for a new class of I- nearly weak uniformly L-Lipschitzian mappings in a real Banach space. The class of I-nearly weak uniformly L-Lipschitzian mappings is an interesting generalization of the class of nearly weak uniformly L-Lipschitzian mappings which inturn is a generalization of the class of nearly unif...

Efficiency is generally the most important aspect to take into account when choosing an iterative method to approximate a solution of an equation, but is not the only aspect to consider in the iterative process. Another important aspect to consider is the accessibility of the iterative process, which shows the domain of starting points from which the iterative process converges to a solution of...
