Title: On the Temporal Granularity on Fuzzy Cognitive Maps
The theory of fuzzy cognitive maps (FCMs) is a powerful approach to
modeling human knowledge that is based on causal reasoning. Taking
advantage of fuzzy logic and cognitive map theories, FCMs enable
system designers to model complex frameworks by defining degrees of
causality between causal objects. They can be used to model and
represent the behavior of simple and complex systems by capturing
and emulating the human being to describe and present systems in
terms of tolerance, imprecision, and granulation of information.
However, FCMs lack the temporal concept that is crucial in many
real-world applications, and they do not offer formal mechanisms to
verify the behavior of systems being represented, which limit
conventional FCMs in knowledge representation. In this webinar, we
present a temporal extension to FCMs by exploiting a theory from
formal languages, namely, the timed automata, which bridges the
aforementioned inadequacies. Indeed, the theory of timed automata
enables FCMs to effectively deal with a double-layered temporal
granularity, extending the standard idea of B-time that
characterizes the iterative nature of a cognitive inference engine
and offering model checking techniques to test the cognitive and
dynamic comportment of the framework being designed. As shown
through experiments, where the proposed approach has been evaluated
by simulating a complex municipality garbage collection system,
TAFCMs improve conventional FCMs by yielding better performance in
terms of representation of dynamic systems behavior.
Giovanni AcamporaDr. Giovanni Acampora received the Laurea (cum laude) and Ph.D.
degrees in Computer Science from the University of Salerno, Salerno,
Italy, in 2003 and 2007, respectively. Since July 2012, he is an
Assistant Professor at the School of Industrial Engineering,
Information Systems, Eindhoven University of Technology, the
Netherlands. From March 2007 to March 2012, he has been a Research
Associate in the Department of Mathematics and Computer Science,
University of Salerno. He was also a Member of the Multi-Agent
Laboratory at the University of Salerno and scientific co-responsible
of the CORISA Research Centre. From September 2003 to June 2007, he
was also in CRDC-ICT Domotic project, where he was engaged in the
research on multi-agent systems and artificial intelligence applied to
ambient intelligence environments. In this context, he designed and
developed the Fuzzy Markup Language, an XML-based environment for
modeling transparent fuzzy systems. Currently, FML is under
consideration by IEEE Standard Association to become the first
standard in the field of computational intelligence. His current
research interests include novel algorithms design approaches inspired
by natural systems as swarm intelligence, evolutionary, and memetic
strategies, investigating the designing of novel human–computer
interaction systems based on integration among haptic hardware,
virtual reality and augmented reality technologies, formal methods
from language theory area, and on the study of temporal effects on the
behavior of fuzzy systems modeled through fuzzy controllers and fuzzy
cognitive maps. He has written some seminal papers on ambient
intelligence and, in particular, his work about fuzzy computation in
smart environments is one of the most cited paper of IEEE Transactions
on Industrial Informatics.
Dr. Acampora serves as reviewer and associate and guest editor for
several international journals and conferences.
Dr. Acampora is the chair of the IEEE Computational Intelligence
Society Standards Committee. In this context, he also served as Chair
of Task Force on Taxonomy and Terminology and Vice-Chair of Task Force
on New Standard Proposal. From 2010, he serves as Secretary and
Treasurer of Italian Chapter of IEEE Computational Intelligence
Society. Currently he is chairing the IEEE Standard Association P1855
Workgroup related to the FML standardization process.
Dr. Vincenzo Loia (SM’08) received the Bachelor’s degree in computer
science from the University of Salerno, Fisciano, Italy, in 1984 and
the Ph.D. degree in computer science from the University of Paris VI,
Paris, France, in 1989. Since 1989, he has been a Faculty member with
the University of Salerno, where he teaches Operating Systems,
Semantic Web, and Multi-Agents Systems. He is currently a Full
Professor of computer science with the Department of Mathematics and
Computer Science. He is the author of more than 190 original research
papers in international journals, e-book chapters, and international
conference proceedings. His current research interests include merging
soft computing and agent technology to design technologically complex
environments, with particular interest in web intelligence
applications. Dr. Loia is the Co-Editor-in-Chief of Soft Computing and
the Editor-in-Chief of Ambient Intelligence and Humanized Computing.
He serves as an Editor for 14 other international journals. He has
been the Chair of the Emergent Technologies Technical Committee of the
IEEE Computational Intelligence Society, where he is currently the
Chair the of Task Force Intelligent Agents.
Autilia Vitiello ( a PhD candidate) received the Laurea degree in Computer Science (cum
laude) from the University of Salerno (Italy) in 2009, discussing the
thesis "Time Sensitive Fuzzy Agents: formal model and implementation"
(advisor Prof. Vincenzo Loia). She is currently a PhD student at
Department of Computer Science of the University of Salerno under the
supervision of Prof. Vincenzo Loia and Dr. Giovanni Acampora. Her
research interests concern computational intelligence, and in
particular, fuzzy logic and knowledge representation theories. In last
years, she is working on evolutionary algorithms, above all, like
means to solve the ontology alignment problem.
