Reasoning about Hierarchical Storage
In this paper, we develop a new substructural logic that can encode invariants necessary for reasoning about hierarchical storage. We show how the logic can be used to describe th...

Comparing Hierarchical Markov Networks and Multiply Sectioned Bayesian Networks
Abstract. Multiply sectioned Bayesian networks (MSBNs) were originally proposed as a modular representation of uncertain knowledge by sectioning a large Bayesian network (BN) into ...
