Background: The link prediction issue is one of the most widely used problems in complex network analysis. Link prediction requires knowing the background of previous link connections and combining them with available information. The link prediction local approaches with node structure objectives are fast in case of speed but are not accurate enough. On the other hand, the global link predicti...

This paper describes the approach proposed by ARTEMISUBIMEDIA team at TRECVID 2011, Instance Search (INS) task. The method is based on a semi-global image representation relying on an over-segmentation of the keyframes. An aggregation mechanism was then applied in order to group a set of sub-regions into an object similar to the query, under a global similarity criterion.

In computer vision and, increasingly, in rendering and image processing, it is useful to lter images with continuous rotated and scaled families of l-ters. For practical implementations, one can think of using a discrete family of lters, and then to interpolate from their outputs to produce the desired ltered version of the image. We propose a multirate implementation of de-formable kernels, ca...

Sequential sampling strategies based on Gaussian processes are now widely used for the optimization of problems involving costly simulations. But Gaussian processes can also generate parallel optimization strategies. We focus here on a new, parameter free, parallel expected improvement criterion for asynchronous optimization. An estimation of the criterion, which mixes Monte Carlo sampling and ...

To obtain consistency and asymptotic normality, a generalized method of moments (GMM) estimator typically is defined to be an approximate global minimizer of a GMM criterion function. To compute such an estimator, however, can be problematic because of the difficulty of global optimization. In consequence, practitioners usually ignore the problem and take the GMM estimator to be the result of a...

OBJECTIVE Remission criteria for schizophrenia have been proposed, consisting of a time criterion and a symptomatic remission criterion. With longitudinal data of a representative patient group (N=317; median follow-up: 1,132 days), validity of the symptomatic remission criterion was investigated. METHOD In a group of 145 patients meeting the symptomatic remission criterion at baseline and a ...

Abstract The purpose of this study is to consider an international facility location problem under uncertainty and present an integrated model for strategic and operational planning. The paper offers two methodologies for the location selection decision. First the extended VIKOR method for decision making problem with interval numbers is presented as a methodology for strategic evaluation of po...

  In this paper flexible job-shop scheduling problem (FJSP) is studied in the case of optimizing different contradictory objectives consisting of: (1) minimizing makespan, (2) minimizing total workload, and (3) minimizing workload of the most loaded machine. As the problem belongs to the class of NP-Hard problems, a new hybrid genetic algorithm is proposed to obtain a large set of Pareto-optima...

In this paper, the global asymptotic stability of delayed cellular neural networks (DCNNs) is investigated. A novel criterion for the stability using the Lyapunov stability theory and linear matrix inequality (LMI) framework is presented. The criterion expressed by LMIs is delay-dependent. The result is less conservative than those established in the earlier references. A numerical example is g...
