BEEM : Bucket Elimination with External Memory
Proceedings of the 26th Conference on Uncertainty in Artificial Intelligence, PMLR R8:276-284, 2010.
Abstract
A major limitation of exact inference algo- rithms for probabilistic graphical models is their extensive memory usage, which often puts real-world problems out of their reach. In this paper we show how we can extend in- ference algorithms, particularly Bucket Elim- ination, a special case of cluster (join) tree de- composition, to utilize disk memory. We pro- vide the underlying ideas and show promis- ing empirical results of exactly solving large problems not solvable before.
