On the Behavior of the Robust Bayesian Combination Operator and the Significance of Discounting

Abstract

We study the combination problem for credal sets via the robust Bayesian combination operator. We extend Walley's notion of degree of imprecision and introduce a measure for degree of conflict between two credal sets. Several examples are presented in order to explore the behavior of the robust Bayesian combination operator in terms of imprecision and conflict. We further propose a discounting operator that suppresses a source given an interval of reliability weights, and highlight the importance of using such weights whenever additional information about the reliability of a source is available.

Keywords. Imprecise probabilities, robust Bayesian combination, credal set, discounting, information fusion
