Estimadas/os:

Tenemos el agrado de invitarlas/os a la charla del Ondrej Majer
(Czech Academy of Sciences) quien visitará el
Departamento de Matemática durante la próxima semana.

La charla se realizará el día miércoles 13 de noviembre a las 11:00 hs en la
Sala de Conferencias (Edificio Abuelas de Plaza de Mayo).

Aquí les dejamos la información de la charla:

Título: Representation of imperfect information in epistemic logics

Resumen:
Agents represented in standard systems of epistemic logics are usually
idealized as well as information they process. The agents are perfect
logical thinkers and they deal with complete and consistent information.
Real agents on the other hand have limited cognitive capacity and they have
to make decisions based on information, which is not only incomplete, but
also inconsistent. The situation in frameworks dealing with uncertain
information is similar, agents are e.g. supposed to provide their degrees
of uncertainty reflecting their subjective probabilities of all events with
an unrealistic precision. In this presentation we present a framework the
main aim of which is to relax some of these idealizations. In particular we
introduce a framework for representing incomplete and/or inconsistent
information which might also be uncertain. Formally our framework consists
in introducing various uncertainty measures over Belnap-Dunn logic. This
logic was designed to deal with inconsistent and/or incomplete information,
its extension with uncertainty measures allows to specify not only degrees
of belief in information supporting truth/falsity of a proposition, but
also a degree of its incompleteness and inconsistency. We focus on the
dynamics of this kind of information and present some methods of updating
of the presented uncertainty measures. In particular we provide some
non-classical variants of Bayes and Jeffrey conditioning of these measures
and discuss some methods of their aggregation.
