Abstract:
Due to its importance in a number of fields, the problem
of classification or classes discrimination in
information systems has been approached by multiple
authors, and various methods to address this issue have
been developed. The combination of rough sets and fuzzy
logic for classification is a widely adopted method.
Rough set theory helps in minimizing the number of
attributes that influence the selection and fuzzy logic
permits to discriminate when there is more than one
possible solution for the same attributes and intervals.
Neural networks and information entropy have also been
used to discriminate. When information is diffuse and
the number of obtained values for each attribute is
large, such is the number of rules for any type of
solution method. Due to this fact, interval-valued
information systems have been proposed by several
authors, in which an interval of values is defined for
each attribute, moving from the minimum to the maximum
obtained values in the database or using the standard
deviation from the original data to define the minimum
and maximum values. Differently from other works, the
concept of information measure is used in this paper,
together with a fuzzy logic discrimination tool. Using
these concepts, an attribute reduction is initially
obtained and then fuzzy logic is applied for
discriminating among the possible solutions. The method
results simpler than others, and as accurate as the
methods usually employed.
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 his Professional
Engineer License from the state of Florida, USA. For
more than 20 years he taught and performed research at
the Higher Polytechnic Institute of Havana, where he
earned 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 was awarded medals in
recognition of his work from the Cuban Ministry of
Higher Education and at the Technical University of
Brno, in Czech Republic, where he participated in a
post-doctoral Study in robotics and did research with
the Faculty. Dr. Caballero 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 text books and one
monograph in the area of automatic control and obtained
five certificates of invention in the same area. He also
wrote published research reports and papers, published
in scientific journals and conference proceedings. In
total he has over 100 publications. Presently, he is a
lecturer 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, and works as a
consultant in electrical engineering.
