Propagation of Belief Functions through Frames of Discernment: Application to
In smart homes, many context attributes, i.e. small pieces of context, have to be computed from sensors in order to provide adapted services. We observe that many of those context attributes can be deduced from others. This paper presents how methods to propagate belief functions from one frame of discernment to another can be used to compute contexts. It enables the creation of evidential netw...
متن کامل2CoBel : An Efficient Belief Function Extension for Two-dimensional Continuous Spaces
This paper introduces an innovative approach for handling 2D compound hypotheses within the Belief Function Theory framework. We propose a polygon-based generic representation which relies on polygon clipping operators. This approach allows us to account in the computational cost for the precision of the representation independently of the cardinality of the discernment frame. For the BBA combi...

متن کاملConstructing Multiple Frames of Discernment for Multiple Subproblems
In this paper we extend a methodology for constructing a frame of discernment from belief functions for one problem, into a methodology for constructing multiple frames of discernment for several different subproblems. The most appropriate frames of discernment are those that let our evidence interact in an interesting way without exhibit too much internal conflict. A function measuring overall...
متن کاملFamilies of compatible frames of discernment as semimodular lattices
Shafer’s mathematical theory of evidence is one of the most remarkable attempts to introduce a complete generalized probability theory. One of its features is the central role of the notion of different level of knowledge of a given phenomenon, embodied into the idea of compatible frames of discernment . In this work we are going to analyze the algebraic basement of the concept of family of fra...
