DSmT: A new paradigm shift for information fusion

TL;DR

DSmT introduces a novel framework for information fusion that effectively manages highly conflicting and uncertain sources, surpassing traditional methods like Dempster-Shafer Theory in complex scenarios.

Contribution

The paper presents the foundations and main rules of DSmT, a new paradigm shift in information fusion capable of handling paradoxical and highly conflicting data.

Findings

DSmT can handle highly conflicting information sources.

It generalizes Dempster-Shafer Theory with broader applicability.

Illustrative examples demonstrate DSmT's effectiveness.

Abstract

The management and combination of uncertain, imprecise, fuzzy and even paradoxical or high conflicting sources of information has always been and still remains of primal importance for the development of reliable information fusion systems. In this short survey paper, we present the theory of plausible and paradoxical reasoning, known as DSmT (Dezert-Smarandache Theory) in literature, developed for dealing with imprecise, uncertain and potentially highly conflicting sources of information. DSmT is a new paradigm shift for information fusion and recent publications have shown the interest and the potential ability of DSmT to solve fusion problems where Dempster's rule used in Dempster-Shafer Theory (DST) provides counter-intuitive results or fails to provide useful result at all. This paper is focused on the foundations of DSmT and on its main rules of combination (classic, hybrid and Proportional Conflict Redistribution rules). Shafer's model on which is based DST appears as a particular and specific case of DSm hybrid model which can be easily handled by DSmT as well. Several simple but illustrative examples are given throughout this paper to show the interest and the generality of this new theory.
