[Viviana Lobo]

Prezados,

dando continuidade ao Ciclo de Palestras do Programa de Pós-Graduação
em Estatística do IM-UFRJ, *na próxima 4a feira,* *18/10/2023  **às 15:30h*,
teremos a palestra da professora e pesquisadora Thais Fonseca. Segue abaixo:


*Palestrante:* Thais Fonseca (Dep. de Métodos Estatísticos, IM/UFRJ)

*Título:* Bayesian Networks: elicitation, temporal modeling and applications

*Resumo: *In ever-larger dynamic systems, it is increasingly difficult for
decision makers to effectively account for all the variables within the
system that may influence the outcomes of interest. This task is even
harder if the system evolves over time. In this context, Bayesian Networks
offer a useful approach designed to account for uncertainties using both
expert knowledge and experimental data. The idea is based on a divide to
conquer strategy and accounts for temporal dependence through dynamical
evolution of model parameters. In this talk, I present applications of
Bayesian networks in healthy, digital preservation and food security. The
graphical structure and probabilities are either estimated or elicited
according to expert information. For the discrete multivariate case, I
present a new temporal evolution based on Dirichlet processes. An online
app designed to be accessible to experts is developed and allows
practitioners to manage risks in decision making under uncertainty.

As palestras ocorrem *de forma presencial *às quartas-feiras às 15:30h
no *Laboratório
de Sistemas Estocásticos no Bloco I sala 044-b (subsolo)*, do Centro de
Tecnologia, Ilha do Fundão da Universidade Federal do Rio de Janeiro.
