To preference via entrenchment

To Preference via Entrenchment

We introduce a simple generalization of G ardenfors and Makinson’s epistemic entrenchment called partial entrenchment. We show that preferential inference can be generated as the sceptical counterpart of an inference mechanism de ned directly on partial entrenchment.

Basic Entrenchment

In contrast to other prominent models of belief change models based on epistemic entrenchment have up to now been applicable only in the context of very strong packages of requirements for belief revision This paper decomposes the axiomatization of entrenchment into independent modules Among other things it is shown how belief revision satisfying only the basic postulates of Alchourr on G arden...

Entrenchment Relations: A Uniform Approach to Nonmonotonicity

We show that Gabbay’s nonmonotonic consequence relations can be reduced to a new family of relations, called entrenchment relations. Entrenchment relations provide a direct generalization of epistemic entrenchment and expectation ordering introduced by Gärdenfors and Makinson for the study of belief revision and expectation inference, respectively.

Psycholinguistic Studies of Entrenchment

Entrenchment-Based Horn Contraction

The AGM framework is the benchmark approach in belief change. Since the framework assumes an underlying logic containing classical Propositional Logic, it can not be applied to systems with a logic weaker than Propositional Logic. To remedy this limitation, several researchers have studied AGM-style contraction and revision under the Horn fragment of Propositional Logic (i.e., Horn logic). In t...
