Rules, Belief Functions and Default Logic
Nic Wilson
This paper describes a natural framework for rules, based on belief functions, which includes a repre- sentation of numerical rules, default rules and rules allowing and rules not…
A Monte-Carlo Algorithm for Dempster-Shafer Belief
Nic Wilson
A very computationally-efficient Monte-Carlo algorithm for the calculation of Dempster-Shafer belief is described. If Bel is the combination using Dempster's Rule of belief functio…
The Assumptions Behind Dempster's Rule
Nic Wilson
This paper examines the concept of a combination rule for belief functions. It is shown that two fairly simple and apparently reasonable assumptions determine Dempster's rule, givi…
Generating Graphoids from Generalised Conditional Probability
Nic Wilson
We take a general approach to uncertainty on product spaces, and give sufficient conditions for the independence structures of uncertainty measures to satisfy graphoid properties.…
An Order of Magnitude Calculus
Nic Wilson
This paper develops a simple calculus for order of magnitude reasoning. A semantics is given with soundness and completeness results. Order of magnitude probability functions are e…
Multi-objective Influence Diagrams
Radu Marinescu, Abdul Razak, Nic Wilson
We describe multi-objective influence diagrams, based on a set of p objectives, where utility values are vectors in Rp, and are typically only partially ordered. These can still be…
