New framework unifies belief change models in AI research

By PulseAugur Editorial · [2 sources] ·

Researchers have introduced Abstract Worlds Semantics (AWS), a new set-theoretic framework for belief change that does not assume any logical syntax. This approach treats worlds as fundamental elements, defining contraction and revision operators over them to unify various belief change models. AWS aims to simplify and generalize belief change theory by providing a homogeneous account of different models, including AGM, KM, and Multiple Change, when applied to classical propositional logic.
