摘要: Abstract This study introduces the concept of conditional independence in valuation-based systems (VBS). VBS is an axiomatic framework capable representing many different uncertainty calculi. We define terms factorization joint valuation. The definition generalizes corresponding probability theory. Besides theory, our applies also to Dempster-Shafer's belief-function Spohn's epistemic-belief and Zadeh's possibility In fact, it any calculi that fit framework. prove satisfies usual properties associated with it. particular, Pearl Paz's graphoid axioms.
