Iterated Belief Change, Computationally

no code implementations17 Feb 2022 Kai Sauerwald, Christoph Beierle

Iterated Belief Change is the research area that investigates principles for the dynamics of beliefs over (possibly unlimited) many subsequent belief changes.

A Conditional Perspective on the Logic of Iterated Belief Contraction

no code implementations4 Feb 2022 Kai Sauerwald, Gabriele Kern-Isberner, Christoph Beierle

For all these principles, we provide semantic characterization theorems and provide formulations by postulates which highlight how the change of beliefs and of conditional beliefs is constrained, whenever that is possible.

AGM Belief Revision, Semantically

no code implementations27 Dec 2021 Faiq Miftakhul Falakh, Sebastian Rudolph, Kai Sauerwald

As our second core contribution, we provide a characterization of all logics for which our result can be strengthened to assignments producing transitive preference relations (as in K&M's original work).

Conditional Inference and Activation of Knowledge Entities in ACT-R

no code implementations28 Oct 2021 Marco Wilhelm, Diana Howey, Gabriele Kern-Isberner, Kai Sauerwald, Christoph Beierle

Activation-based conditional inference applies conditional reasoning to ACT-R, a cognitive architecture developed to formalize human reasoning.

On Limited Non-Prioritised Belief Revision Operators with Dynamic Scope

no code implementations17 Aug 2021 Kai Sauerwald, Gabriele Kern-Isberner, Christoph Beierle

In this paper, we contribute to this line of research by introducing the concept of dynamic-limited revision, which are revisions expressible by a total preorder over a limited set of worlds.

A General Katsuno-Mendelzon-Style Characterization of AGM Belief Base Revision for Arbitrary Monotonic Logics

no code implementations29 Apr 2021 Faiq Miftakhul Falakh, Sebastian Rudolph, Kai Sauerwald

The AGM postulates by Alchourr\'{o}n, G\"{a}rdenfors, and Makinson continue to represent a cornerstone in research related to belief change.

A Conditional Perspective for Iterated Belief Contraction

no code implementations20 Nov 2019 Kai Sauerwald, Gabriele Kern-Isberner, Christoph Beierle

According to Boutillier, Darwiche, Pearl and others, principles for iterated revision can be characterised in terms of changing beliefs about conditionals.

Decrement Operators in Belief Change

no code implementations20 May 2019 Kai Sauerwald, Christoph Beierle

While research on iterated revision is predominant in the field of iterated belief change, the class of iterated contraction operators received more attention in recent years.
