Table 1 provides the average computational time (in minutes) for the eight methods under the simulation settings. SIS clearly requires the least computational effort, whereas RLASSO as well as Scout require much longer computational time. But all methods except RLASSO(CLIME) can be computed under a reasonable amount of time for p = 5000 and n = 100. RLASSO(CLIME) takes much longer because of in...

This work proposes an “ad hoc” new method for variable selection in classification, specifically in Discriminant Analysis. This new method is based on the metaheuristic strategy Tabu Search. From a computational point of view variable selection is a NP-Hard problem and therefore there is no guarantee of finding the optimum solution (NP = Nondeterministic Polynomial Time). This means that when t...

Variable selection methods play an important role in the field of attribute mining. The Naive Bayes (NB) classifier is a very simple and popular classification method that yields good results in a short processing time. Hence, it is a very appropriate classifier for very large datasets. The method has a high dependence on the relationships between the variables. The Info-Gain (IG) measure, whic...

Compositional proof systems for shared variable concurrent programs can be devised by including the interference information in the speciica-tions. The formalism falls into a category called rely{guarantee (or assumption{ commitment), in which a speciication is explicitly (syntactically) split into two corresponding parts. This paper summarises existing work on the rely-guarantee method and giv...

In this paper‎, ‎the aim is to find a complex interval vector [Z] such that satisfies the complex interval linear system C[Z]=[W]‎. ‎For this‎, ‎we present a new method by restricting the general solution set via applying some parameters‎. ‎The numerical examples are given to show ability and reliability of the proposed method.

In this paper, we present an analytical method for solving a well-posed boundary value problem of mathematical physics governing the vibration characteristics of an internal flow propelled fluid-structure interaction where the pipeline segment is idealized as an elastic hollow beam conveying an incompressible fluid on a viscoelastic foundation. The effect of Coriolis and damping forces on the o...

The interrelationship between software faults and failures is quite intricate and obtaining a meaningful characterization of it would definitely help the testing community in deciding on efficient and effective test strategies. Towards this objective, we have investigated and classified failures observed in a large complex telecommunication industry middleware system during 20032006. In this pa...

This paper is concerned with the numerical approximation of definite integrals over [—1, 1], in which the function /to be integrated has isolated singularities near [ —1, 1 ]. Complex variable techniques are used to study the effectiveness of the method of subtracting out complex singularities.
