Graph-Based Search Procedure for Vector Autoregressive Models [PDF]

open access: yes
Vector Autoregressions (VARs) are a class of time series models commonly used in econometrics to study the dynamic effect of exogenous shocks to the economy.

Box-constrained vector optimization: a steepest descent method without “a priori” scalarization [PDF]

open access: yes
In this paper a notion of descent direction for a vector function defined on a box is introduced. This concept is based on an appropriate convex combination of the “projected” gradients of the components of the objective functions.

A propagation of chaos result for a system of particles with moderate interaction

open access: yes
This paper is concerned with the asymptotic behaviour of a system of particles with moderate interaction. The main result is a propagation of chaos result which generalizes a convergence result of Oelschläger.

Using divergence free wavelets for the numerical solution of the Stokes problem

open access: yes, 1996
The divergence free formulation of the Stokes problem leads to a positive definite system of reduced size for the velocity, provided that divergence free trial spaces are available.

Benchmarking least squares support vector machine classifiers. [PDF]

open access: yes
In Support Vector Machines (SVMs), the solution of the classification problem is characterized by a ( convex) quadratic programming (QP) problem. In a modified version of SVMs, called Least Squares SVM classifiers (LS-SVMs), a least squares cost function
