Belief Revision in the Context of Abductive Explanation
نویسنده
چکیده
This proposal presents an approach to explanation that incorporates the paradigms of belief revision and abduction. We present an algorithm that combines these techniques and a system called Brace that is a preliminary implementation of this algorithm. We show the applicability of the Brace approach to a wide range of domains including scienti c discovery, device diagnosis and plan recognition. Finally, we describe our proposals for a new implementation, new application domains for our system and extensions to this approach.

UEcho: A Model of Uncertainty Management in Human Abductive Reasoning
This paper explores the uncertainty aspects of human abductive reasoning. Echo, a model of abduction based on the Theory of Explanatory Coherence (Thagard, 1992a), captures many aspects of human abductive reasoning, but fails to sufficiently manage the uncertainty in abduction. In particular, Echo does not handle belief acquisition and dynamic belief revision, two essential components of human ...
متن کاملAbductive Expansion: Abductive Inference and the Process of Belief Changey
Unlike the AGM framework of belief revision, where new information is added to the current belief state as it is (while attempting to preserve logical consistency), we model the following more natural proposal: agents seek a justiication (explanation) for the new information before \accepting" it and incorporate this justiication into their current belief state together with the new information...

متن کاملOn Explanatory Belief revision systems: Initiation Grant Proposal
In this project, a newmodel for belief revision based on abduction will be elaborated within the framework of AGM belief revision. We construe “abduction” as the process of reasoning in which explanatory (causal) hypothesis are formed and evaluated. Our basic hypothesis is that agent seeks explanation, before she accepts and integate the new evidential information with the old. As a result, it ...
