This paper introduces a framework for relevant belief revision. We represent agent’s beliefs in prime implicants and express agent’s preference on beliefs as a pre-order over terms. We define a belief revision operator via minimising the change of the prime implicants of the existing beliefs and the incoming information with respect to agent’s preferences. We show that such a belief revision op...

Intelligent agents require methods to revise their epistemic state as they acquire new information. Jeffrey’s rule, which extends conditioning to uncertain inputs, is used to revise probabilistic epistemic states when new information is uncertain. This paper analyses the expressive power of two possibilistic counterparts of Jeffrey’s rule for modeling belief revision in intelligent agents. We s...

We describe a model of iterated belief revision that extends the AGM theory of revision to account for the effect of a revision on the conditional beliefs of an agent. In particular, this model ensures that an agent makes as few changes as possible to the conditional component of its belief set. Adopting the Ramsey test, minimal conditional revision provides acceptance conditions for arbitrary ...

Semantic structures for belief revision are proposed. We start with one-stage revision structures that generalize the notion of choice function from rational choice theory. A correspondence between these one-stage structures and AGM belief revision functions is established. We then add branching time and consider more general structures that accommodate iterated revision. AGM temporal revision ...

Revision history Revision 0 (3 May 2006) First revision Revision 1 (10 June 2006) Incorporated comments from May 2006 CAP WG changed to SET/REPORT DEVICE IDENTIFIER commands instead of the Device Identification VPD page 83h. Revision 2 (7 September 2006) Incorporated comments from July 2006 CAP WG renamed to SET/REPORT IDENTIFYING INFORMATION to avoid overuse of “identifier”, increased the info...

We point out that current belief revision operations can be used to revise non-monotonic theories and we propose a new operation, called permissive belief revision. The underlying idea of permissive belief revision consists of instead of abandoning some beliefs during a revision, transforming those beliefs into weaker ones, while still keeping the resulting belief set consistent. This framework...

This paper presents experimental evidence concerned with behavior in Cournot duopolies where players indulge in a form of pre-play communication termed as revision phase before playing the “one-shot” game. During this revision phase individuals announce their tentative quantities that are publicly observed and revisions are costless. The payoffs are determined only by the quantities selected at...

BACKGROUND The published data on pain and physical function before and after revision of total hip arthroplasty (THA) is scarce. The study reports the course and interrelationships of radiographic loosening, pain and physical function 5 year before and after a first revision THA. METHODS The study was based on the IDES-THA database. All patients with their first THA revision for aseptic loose...
