BELIEF FUNCTIONS AND THE TRANSFERABLE BELIEF MODEL
Philippe Smets · 2000
Belief functions have been proposed for modeling someone's de- grees of belief. They provide alternatives to the models based on probability functions or on possibility functions. There are several interpretations of belief functions: the lower probabilities model, Dempster's model, the hint model, the probability of modal propositions model, the transferable belief model. All these models are unfortunately clustered under the generic name of Dempster{ Shafer theory, which hides their dierences and explains most of the confusion and errors that appear in the literature.
