A View of the Em Algorithm that Justifies Incremental, Sparse, and other Variantstion for only one of the unobserved variables is recalculated in each E step. This variant is shown empirically to give faster convergence in a mixture estimation problem. A variant of the algorithm that exploits sparse conditional distributions is also described, and a wide range of other variant algorithms are also seen to be possible.

Inference in Bayesian Networks Using Nested Junction Treesuch reductions. The usefulness of the method is emphasized through a thorough empirical evaluation involving ten large real-world Bayesian networks and both the Hugin and the Shafer-Shenoy inference algorithms.

Advanced Inference in Bayesian NetworksThe previous chapter introduced inference in discrete variable Bayesian networks. This used evidence propagation on the junction tree to find marginal distributions of interest. This chapter presents a tutorial introduction to some of the various types of calculations which can also be performed with the junction tree, specifically:
