Causal Compositional Models in Valuation-Based Systems
This paper shows that Pearl’s causal networks can be described using compositional models in the valuation-based systems (VBS) framework. There are several advantages of using the VBS framework. First, VBS is a generalization of several uncertainty theories (e.g., probability theory, a version of possibility theory where combination is the product t-norm, Spohn’s epistemic belief theory, and De...
متن کاملCompositional Models in Valuation-Based Systems
Compositional models were initially described for discrete probability theory, and later extended for possibility theory and for belief functions in Dempster-Shafer (D-S) theory of evidence. Valuation-based system (VBS) is an unifying theoretical framework generalizing some of the well known and frequently used uncertainty calculi. This generalization enables us to not only highlight the most i...
متن کاملConditioning in Decomposable Compositional Models in Valuation-Based Systems
Valuation-based systems (VBS) can be considered as a generic uncertainty framework that has many uncertainty calculi, such as probability theory, a version of possibility theory where combination is the product t-norm, Spohn’s epistemic belief theory, and DempsterShafer belief function theory, as special cases. In this paper, we focus our attention on conditioning, which is defined using the co...
