Incremental kernel learning algorithms and applications.

Since the Support Vector Machines (SVMs) were introduced in 1995, SVMs have been recognized as essential tools for pattern classification and function approximation. Numerous publications show that SVMs outperform other learning methods in various areas. However, SVMs have a weak performance with large-scale data sets because of high computational complexity. One approach to overcome this limitation is the incremental learning approach where a large-scale data set is divided into several subsets and trained on those subsets updating the core information extracted from the previous subset. This approach also has a drawback that the core information is accumulated during the incremental procedure. When the large-scale data set has a special structure (e.g., in the case of unbalanced data set), the standard SVM might not perform properly. In this study, a novel approach based on the reduced convex hull concept is developed and applied in various applications. In addition, the developed concept is applied to the Support Vector Regression (SVR) to produce better performance. From the performed experiments, the incremental revised SVM significantly reduces the number of support vectors and requires less computing time. In addition the incremental revised SVR produces similar results with the standard SVR by reducing computing time significantly. Furthermore, the filter concept developed in this study may be utilized to reduce the computing time in other learning approach

Design of a Controlled Language for Critical Infrastructures Protection

We describe a project for the construction of controlled language for critical infrastructures protection (CIP). This project originates from the need to coordinate and categorize the communications on CIP at the European level. These communications can be physically represented by official documents, reports on incidents, informal communications and plain e-mail. We explore the application of traditional library science tools for the construction of controlled languages in order to achieve our goal. Our starting point is an analogous work done during the sixties in the field of nuclear science known as the Euratom Thesaurus.JRC.G.6-Security technology assessmen

Organizing the fight technological determinants of coalition command and control and combat operations

Despite the political impetus for greater multilateralism in international military operations, recent coalitions including U.S. forces reflect a trend toward increasing U.S. dominance and decreasing allied participation. As the United States continues to invest in its military with research, development and acquisition budgets at least double that of any other nation, it fields technologies so advanced with respect to its allies as to leave them incompatible for combined operations. Recent coalition operations suggest that there is a close relationship between technological asymmetries created by partner contributions and the structures formed as the coalition assembles. Using Desert Storm and Operation Allied Force as case studies, this thesis identifies a systemic relationship between technological advantage and coalition dominance. As a coalition seeks to reduce aggregate risk, it relies on technologies that offer the greatest effectiveness. This reliance causes the coalition to divert combat burden to the technologically dominant partner which, in turn, imposes its operational culture. This thesis concludes that the technological transformation currently underway in the U.S. Department of Defense conflicts with U.S. political initiatives to promote greater multilateralism in combat operations by forcing allies to rely on U.S. technologies thereby creating more unilateral operations.http://archive.org/details/organizingfightt109452656Outstanding ThesisApproved for public release; distribution is unlimited

Trade-off analysis of modes of data handling for earth resources (ERS), volume 1

Data handling requirements are reviewed for earth observation missions along with likely technology advances. Parametric techniques for synthesizing potential systems are developed. Major tasks include: (1) review of the sensors under development and extensions of or improvements in these sensors; (2) development of mission models for missions spanning land, ocean, and atmosphere observations; (3) summary of data handling requirements including the frequency of coverage, timeliness of dissemination, and geographic relationships between points of collection and points of dissemination; (4) review of data routing to establish ways of getting data from the collection point to the user; (5) on-board data processing; (6) communications link; and (7) ground data processing. A detailed synthesis of three specific missions is included

Expanding Eco-Visualization: Sculpting Corn Production

This dissertation expands upon the definition of eco-visualization artwork. EV was originally defined in 2006 by Tiffany Holmes as a way to display the real time consumption statistics of key environmental resources for the goal of promoting ecological literacy. I assert that the final forms of EV artworks are not necessarily dependent on technology, and can differ in terms of media used, in that they can be sculptural, video-based, or static two-dimensional forms that communicate interpreted environmental information. There are two main categories of EV: one that is predominantly screen-based and another that employs a variety of modes of representation to visualize environmental information. EVs are political acts, situated in a charged climate of rising awareness, operating within the context of environmentalism and sustainability. I discuss a variety of EV works within the frame of ecopsychology, including EcoArtTech’s Eclipse and Keith Deverell’s Building Run; Andrea Polli’s Cloud Car and Particle Falls; Nathalie Miebach’s series, The Sandy Rides; and Natalie Jeremijenko’s Mussel Choir. The range of EV works provided models for my creative project, Sculpting Corn Production, and a foundation from which I developed a creative methodology. Working to defeat my experience of solastalgia, Sculpting Corn Production is a series of discrete paper sculptures focusing on American industrial corn farming. This EV also functions as a way for me to understand our devastated monoculture landscapes and the politics, economics, and related areas of ecology of our food production
