Plenary Lecture

Classification in Interval-Valued Information Systems



Professor Amaury A. Caballero
Lecturer and Advisor
Department of Electrical and Computer Engineering
Florida International University
Miami, Florida, USA
E-mail: caballer@fiu.edu


Abstract:
The use of information theory, rough sets and fuzzy logic helps in extracting important facts from an information system and to discriminate among the different objects, classes or decisions. The minimization of attributes or key facts that influence any selection is the first step when dealing with raw data, where the important information is hidden making the selection complicated. When information is diffuse and the number of obtained values for each attribute is large, so is the number of rules in the discrimination process. Due to this fact, an interval of values is defined for each attribute, moving from the minimum to the maximum obtained values in the database. This is what is defined as interval-valued information systems. Differently from other works, the concept of information measure is used here, together with a fuzzy logic discrimination tool. Using these concepts, initially the key facts are identified (attribute reduction) and then fuzzy logic is applied for discriminating among the possible solutions. The method results simpler than others, and gives accuracy not less than the usually employed methods.


Brief Biography of the Speaker:
Amaury A. Caballero obtained his Bachelor Degree in Electrical Engineering from the University of Havana, Cuba, earned his Ph.D. in Technical Cybernetics from the Energy Institute of Moscow, Russia, and the Professional Engineer License from the state of Florida, USA. He taught and did researches for more than 20 years at the Higher Polytechnic Institute of Havana, where he obtained the category of Full Professor and directed research in the areas of Automatic Control and Robotics. He was also a member of the Higher Scientific Council of the Cuban Academy of Sciences and received medals recognizing his work from the Cuban Ministry of Higher Education and the Technical University of Brno, in Czech Republic, where participated in a post-doctoral Study in robotics and in research with the Faculty of this University. Has been invited to give speeches at the “Universidad de Pamplona” in Colombia, the “Universidad Catolica de Santa Maria” in Peru, the “Universidad Tecnologica Centroamericana” in Honduras, and the “Universidad Autonoma Estatal del Estado de Hidalgo” in Mexico, where he also imparted a graduate course in fuzzy logic. He has published two books in the area of automatic control and obtained five certificates of invention in the same area. He also wrote published research reports, journals papers and proceedings in scientific conferences. In total he has over 100 publications. Presently, he works as a consultant in electrical engineering and is a lecturer and advisor at Florida International University where he teaches in the department of Electrical and Computer Engineering, and has conducted in-depth research in the areas of automation applied to construction management and in fuzzy logic applications.
