A Unified Framework of Propositional Knowledge Base Revision and Update Based on State Transition Models

Belief revision and belief update are two of the most basic types of belief change operations. We need to select either revision or update when we accept new information into the current belief, however, such decision making has not been considered. In this paper, we propose a unified framework of revision and update based on state transition models that enable us to do such decision making. Th...

A unified computational modeling approach to decision making

For centuries, theorists have focused almost exclusively on the use of additive utility representations in attempts to describe decision behavior. This basic framework has constantly been modified in order to account for challenging empirical results. However, each revision to the basic theory has in turn consistently been confronted with conflicting evidence. Here, we summarize an alternative ...

Decision Making in a Context where Uncertainty is Represented by Belief Functions

A quantified model to represent uncertainty is incomplete if its use in a decision environment is not explained. When belief functions were first introduced to represent quantified uncertainty, no associated decision model was proposed. Since then, it became clear that the belief functions meaning is multiple. The models based on belief functions could be understood as an upper and lower probab...

Belief Revision as Applied Within a Descriptive Model of Jury Deliberations

Belief revision is a well-research topic within AI. We argue that the new model of belief revision as discussed here is suitable for general modelling of judicial decision making, along with extant approach as known from jury research. The new approach to belief revision is of general interest, whenever attitudes to information are to be simulated within a multi-agent environment with agents ho...
