Nl. Zhang et L. Yan, INDEPENDENCE OF CAUSAL INFLUENCE AND CLIQUE TREE PROPAGATION, International journal of approximate reasoning, 19(3-4), 1998, pp. 335-349
This paper explores the role of independence of causal influence (ICI)
in Bayesian network inference. ICI allows one to factorize a conditio
nal probability table into smaller pieces. We describe a method for ex
ploiting the factorization in clique tree propagation (CTP) - the stat
e-of-the-art exact inference algorithm for Bayesian networks (BNS). We
also present empirical results showing that the resulting algorithm i
s significantly more efficient than the combination of CTP and previou
s techniques for exploiting ICI. (C) 1998 Published by Elsevier Scienc
