The Normative Representation of Quantified Beliefs by Belief Functions
نویسنده
چکیده
The use of belief functions has recently been advocated as an alternative to the use of probability functions in order to represent quantified beliefs. Such a proposal lacked justification. We present a set of requirements that justify the use of belief functions. The assessment of the validity of these requirements provides a tool for assessing the relative value of normative models of subjective behaviors.

belief function and the transferable belief model
Beliefs are the result of uncertainty. Sometimes uncertainty is because of a random process and sometimes the result of lack of information. In the past, the only solution in situations of uncertainty has been the probability theory. But the past few decades, various theories of other variables and systems are put forward for the systems with no adequate and accurate information. One of these a...
متن کاملThe Axiomatic Justification of the Transferable Belief Model
Belief functions have recently been advocated as an alternative to probability functions for representing quantified belief. This new normative model has several merits, but these merits are not sufficient to justify its use. Some ‘axiomatic’ justification is also needed. Indeed the examination of the requirements that underlie the normative models of subjective behaviors provides usually the b...

This note is a very short presentation of the transferable belief model (TBM), a model for the representation of quantified beliefs based on belief functions. Details must be found in the recent literature. The TBM covers the same domain as the subjective probabilities except probability functions are replaced by belief functions which are much more general. The model is much more flexible than...

متن کاملThe transferable belief model for quantified belief representation
The transferable belief model is a model to represent quantified beliefs based on the use of belief functions, as initially proposed by Shafer. It is developed independently from any underlying related probability model. We summarize our interpretation of the model and present several recent results that characterize the model. We show how rational decision must be made when beliefs are represe...
