Improving interpretability in approximative fuzzy models via multiobjective evolutionary algorithms

INTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 9 2007
A.F. Gómez-Skarmeta
Current research lines in fuzzy modeling mostly tackle improving the accuracy in descriptive models and improving of the interpretability in approximative models. This article deals with the second issue, approaching the problem by means of multiobjective optimization in which accuracy and interpretability criteria are simultaneously considered. Evolutionary algorithms are especially appropriated for multiobjective optimization because they can capture multiple Pareto solutions in a single run of the algorithm. We propose a multiobjective evolutionary algorithm to find multiple Pareto solutions (fuzzy models) showing a trade-off between accuracy and interpretability. Additionally, neural-network-based techniques in combination with ad hoc techniques for improving interpretability are incorporated into the multiobjective evolutionary algorithm to improve the efficiency of the algorithm. © 2007 Wiley Periodicals, Inc.

Measuring the edge-to-edge available bandwidth in a DiffServ domain

INTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 5 2008
N. Blefari-Melazzi
The new Internet will be deployed with a number of tools for network management and quality of service control. To this end, we focus on a single administrative domain based on the Differentiated Services architectural model, and we recognize the need for two main functions for each supported traffic class: an admission control procedure, and a monitoring of the edge-to-edge bandwidth availability. In this work, we specifically focus on the second issue. To preserve scalability and thus to be compliant with Differentiated Services architecture, we propose stateless and distributed procedures based on traffic measurements. Our technique tests network resources by means of ,special' probing packets, which have the task of implicitly conveying the network status to its edges. We show by means of simulations the effectiveness of our solutions, in spite of a very low overhead. Copyright © 2007 John Wiley & Sons, Ltd. [source]

Integration of colour and textural information in multivariate image analysis: defect detection and classification issues

JOURNAL OF CHEMOMETRICS, Issue 1-2 2007
J. M. Prats-Montalbán
Abstract In industrial processes, the detection and visualisation of defects and the development of efficient automated classification tools are strategic issues, especially when dealing with random colour textures (RCTs). This paper discusses the benefits of integrating colour and spatial (i.e. textural) information of digital RGB colour images in multivariate image analysis (MIA) to deal with these topics. Regarding the first one, a simple and computational cost-effective monitoring procedure based on colour-textural MIA merged with multivariate statistical process control (MSPC) ideas is outlined. Two novel computed images: T2 and RSS Images are proposed. The procedure is applied on digital RGB colour images from artificial stone plates. With respect to the second issue, when colour-textural MIA is used for image classification a lot of factors (e.g. pre-processing, modelling,,,) likely affecting the success rate in the classification (SRC) show up. This paper presents a methodology based on the combination of experimental design and logistic regression for choosing the best combination of factors to maximise the SRC of different types of images. Digital RGB colour images from ceramic tiles and orange fruits are used to illustrate the potential of the proposed methodology. Copyright © 2007 John Wiley & Sons, Ltd. [source]

A Decade of Europe?

JOURNAL OF LAW AND SOCIETY, Issue 2 2003
Some Reflections on an Aspiration
This article suggests that Europe faces four primary challenges today. The first relates to democracy, as all the anxieties about the ,democratic deficit' in Community are writ even larger in the Union. A second issue is that of liberal legalism. Lawyers have long presumed that the ,new' Europe has been integrated ,through' law. This article suggests that the role of law is of far less importance to the future of the Union. A third problem, perhaps the most pressing, relates to enlargement. Is the ,new' Europe fully prepared for the inevitable shock that will follow the much-vaunted ,big bang'? Finally, there is the overarching problem of a continuing lack of ethos, or public philosophy, underpinning public life in the ,new' Europe. [source]

The Textual Criticism of Middle English Manuscript Traditions: A Survey of Critical Issues in the Interpretation of Textual Data

LITERATURE COMPASS (ELECTRONIC), Issue 6 2009
Gavin Cole
This essay is intended to survey two broad issues which determine the use of textual data. The first is the underlying orientation towards the use of textual data and how this relates to critical evaluations of agency, authority and materiality. This essay surveys two broad orientations: (i) an essentially retrospective genetic orientation and, (ii) an orientation which focuses on the phenomenon of change. Both approaches are dependent on the ability to distinguish original readings from scribal readings, identify genetic relationships and account for acts of horizontal transmission. With this in mind, the second issue with which this essay is concerned is the importance of critical interpretation in the categorisation of textual data. This essay argues that textual criticism is a practical demonstration of the difficulties of interpretation and that no textual data ,has any real evidential value until it has been interpreted' (Patterson 90).

6th International Workshop on Expert Evaluation & Control of Compound Semiconductor Materials & Technologies

PHYSICA STATUS SOLIDI (A) APPLICATIONS AND MATERIALS SCIENCE, Issue 1 2003
Bálint P
The EXMATEC workshops are a series of biannial conferences with the aim to bring together research and development specialists involved in compound semiconductor material physics, chemistry, process technology, characterization and device fabrication. EXMATEC 2002 is the continuation of successful meetings, previously held in Lyon, Parma, Freiburg, Cardiff and Heraklion. The central topics were development, improvement and application of new and advanced methods in the fabrication and evaluation of compound semiconductor materials and structures to develop understanding of the interrelationship between structural, electrical and other material properties and device characteristics, such as performance, reliability, reproducibility, lifetime, yield, etc. The conference topics apply to all compound semiconductor materials (III,V, II,VI, IV,IV, II,IV,V2), related structures and processing steps (from substrate and epitaxial growth to complete devices) and cover instrumentation and characterization issues. The full Proceedings of EXMATEC 2002 are published in the second issue of the new journal series physica status solidi , conferences Vol. 0, No. 2 (2003). As one representative example of the topics presented at this conference, the cover picture of the present issue issue of phys. stat. sol. (a) shows the band scheme of a typical GaInAs/AlInAs superlattice quantum cascade laser, taken from the invited paper by Razeghi and Slivken [1]. [source]

Research an exciting journey and a career statement: a means to an end, putting rurality on the nursing research agenda

AUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 6 2004
Sonia Allen
Abstract Two issues were of importance to nurses in rural areas considering postgraduate studies. The first was the need for part-time study and what this entails. The second was a request that there be no research component within the postgraduate courses they identified. It is this second issue that I wish to address. I was a nonbeliever in the merit of research studies being integrated into nursing specialist programs. Following a long career in rural clinical nursing and management I have come full circle and now acknowledge the need to understand the role to base practice evidence that is generated through empirical research.
