Research Project: Geometry of General Belief Combination
In this project, we start to extend this geometric analysis to several other major combination operators, including Yager's and Dubois' rules, but also the disjunctive operator. The final objective of the research programme is a comparative geometric analysis of combination rules, which would eventually allow us to describe the `cone' of possible future belief states under stronger or weaker assumptions on reliability and independence of sources, associated with conjunctive and disjunctive combination. The bulk of the analysis focusses on standard, normalised belief functions, but we will also consider unnormalised belief functions to provide some preliminary results.
