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.
