Fast-Division Architecture for Dempster-Shafer Belief Functions

Given a number of Dempster-Shafer belief functions there are different architectures which allow to do a compilation of the given knowledge. These architectures are the Shenoy-Shafer Architecture, the Lauritzen-Spiegelhalter Architecture and the HUGIN Architecture. We propose a new architecture called ”Fast-Division Architecture” which is similar to the former two. But there are two important advantages: (i) results of intermediate computations are always valid Dempster-Shafer belief functions and (ii) some operations can often be performed much more efficiently.
