A Joint Characterization of Belief Revision Rules1
نویسندگان
چکیده
This paper characterizes di¤erent belief revision rules in a uni ed framework: Bayesian revision upon learning some event, Je¤rey revision upon learning new probabilities of some events, Adams revision upon learning some new conditional probabilities, and dual-Je¤reyrevision upon learning an entire new conditional probability function. Though seemingly di¤erent, these revision rules follow from the same two principles: responsiveness, which requires that revised beliefs be consistent with the learning experience, and conservativeness, which requires that those beliefs of the agent on which the learning experience is silent(in a technical sense) do not change. So, the four revision rules apply the same revision policy, yet to di¤erent kinds of learning experience.

Belief revision generalized: A joint characterization of Bayesís and Je§reyís rules
We present a general framework for representing belief-revision rules and use it to characterize Bayesís rule as a classical example and Je§reyís rule as a non-classical one. In Je§reyís rule, the input to a belief revision is not simply the information that some event has occurred, as in Bayesís rule, but a new assignment of probabilities to some events. Despite their di§erences, Bayesís and J...
متن کاملA Unified Model of Qualitative Belief Change: A Dynamical Systems Perspective
Belief revision and belief update have been proposed as two types of belief change serving different purposes, revision intended to capture changes in belief state reflecting new information about a static world, and update intended to capture changes of belief in response to a changing world. We argue that routine belief change involves elements of both and present a model of generalized updat...
متن کاملDescribing Plan Recognition as Nonmonotonic Reasoning and Belief Revision
We provide a characterization of plan recognition in terms of a general framework of belief revision and non-monotonic reasoning. We adopt a generalization of classical belief revision to describe a competence model of plan recognition which supports dynamic change to all aspects of a plan recognition knowledge base, including background knowledge, action descriptions and their relationship to ...
