Total belief theorem and conditional belief functions [PDF]
International Journal of Intelligent Systems, 2018 In this paper, new theoretical results for reasoning with belief functions are obtained and discussed. After a judicious decomposition of the set of focal elements of a belief function, we establish the total belief theorem (TBT).

Depth-bounded Belief functions [PDF]
International Journal of Approximate Reasoning, 2020 This paper introduces and investigates Depth-bounded Belief functions, a logic-based representation of quantified uncertainty. Depth-bounded Belief functions are based on the framework of Depth-bounded Boolean logics [4], which provide a hierarchy of ...

On conditional belief functions [PDF]
International Journal of Approximate Reasoning, 1994 Criteria for establishing conditional belief functions are suggested, and the advantages and disadvantages of conditional belief functions that have been suggested before are discussed.

A correlation coefficient of belief functions [PDF]
International Journal of Approximate Reasoning, 2016 How to manage conflict is still an open issue in Dempster–Shafer (D-S) evidence theory. The conflict coefficient k in D-S evidence theory cannot represent conflict reasonably, especially sometimes two Basic Probability Assignments (BPAs) are identical ...

Distributed combination of belief functions
Information Fusion, 2021 We consider the problem of combining belief functions in a situation where pieces of evidence are held by agents at the node of a communication network, and each agent can only exchange information with its neighbors.

Belief Functions on Distributive Lattices
Proceedings of the AAAI Conference on Artificial Intelligence, 2021 The Dempster-Shafer theory of belief functions is an important approach to deal with uncertainty in AI.In the theory, belief functions are defined on Boolean algebras of events. In many applications of belief functions in real world problems, however,

Belief functions on lattices [PDF]
International Journal of Intelligent Systems, 2009 International audienceWe extend the notion of belief function to the case where the underlying structure is no more the Boolean lattice of subsets of some universal set, but any lattice, which we will endow with a minimal set of properties according to ...

Hidden Conflicts of Belief Functions
International Journal of Computational Intelligence Systems, 2020 In this paper, hidden conflicts of belief functions are observed in the case where the sum of all multiples of the conflicting belief masses equals zero.

Algorithms for combining belief functions [PDF]
International Journal of Approximate Reasoning, 1992 In general, combining Dempster-Shafer belief functions over a frame of n elements is a problem with exponential time complexity in n. This is a consequence of an exponential number of focal elements being generated when the focal elements of the belief ...

Belief Functions on Real Numbers. [PDF]
International Journal of Approximate Reasoning, 2005 We generalize the TBM (transferable belief model) to the case where the frame of discernment is the extended set of real numbers R = [−∞, ∞], under the assumptions that ‘masses’ can only be given to intervals.
