Title in Portuguese
Derivadas em redes Bayesianas usando eliminação de variáveis.
Keywords in Portuguese
Inferência bayesiana
Inteligência artificial
Abstract in Portuguese
Redes Bayesianas são extensivamente usadas em inteligência artificial, reconhecimento de padrões e identificação de sistemas. Uma operação importante é a diferenciação de redes Bayesianas; isto é, o cálculo de derivadas de parâmetros de uma rede Bayesiana. Este trabalho apresenta um novo método para este cálculo: apresentamos um algoritmo baseado no método de eliminação de variáveis, e discutimos as vantagens e aplicações deste novo algoritmo.

Abstract in English
Bayesian networks are extensively used in artificial intelligence, pattern recognition and system identification. An important operation is the differentiation of Bayesian networks; that is, the computation of derivatives for the parameters of a Bayesian networks. This work presents a new method for such a computation: we present an algorithm based on the variable elimination method, and discuss the advantages and applications of this new algorithm
