【Abstract】 Case-based decision theory (CBDT) which combines principles from decision theory and case-based reasoning is studied. A CBDT formalization based on possibility theory and case-based reasoning is presented, which is realized as a two-stage process. In the first stage, the decision maker applies case-based reasoning for quantifying his uncertainty associated with different decisions in form of possibility distributions over the set of consequences. In the second stage, generalizations of expected utility theory is used for choosing acts among associated distributions.更多还原
