Advances and Applications of DSmT for Information Fusion by Florentin Smarandache, Jean Dezert

By Florentin Smarandache, Jean Dezert

This publication offers the hot theoretical advances and purposes of the Dezert-Smarandache idea (DSmT) of believable and paradoxical reasoning for info fusion. DSmT proposes a brand new mathematical framework to accommodate the combo of doubtful, obscure and hugely conflicting resources of data expressed by way of generalized simple trust capabilities. DSmT works past the bounds of the Dempster-Shafer thought and proposes a brand new basic rule of mixture which doesn't require a normalization step and works with any versions (free DSm, hybrid DSm and Shafer's version) regardless of the measure of clash among resources is. The DSmT is definitely tailored for static and dynamic fusion problematics and permits to paintings on any finite frames (discrete, non-stop and/or hybrid). accordingly it might probably mix trust capabilities no matter if the refinement of the body of discernment is inaccessible as a result of the imprecise, relative, and obscure intrinsic nature of its components. half 1 of this e-book provides in info the final investigations on DSmT but in addition a few similar theoretical works with different methods for info fusion. half 2 of the ebook offers fascinating functions of DSmT for fixing either educational fusion difficulties and real-world fusion difficulties.

Collected works are via S. Corgne, F. Dambreville, M. Daniel, D. De Brucq, J. Dezert, M. Farooq, L. Hubert-Moy, A.-L. Jousselme, S. Kadambe, M. Khoshnevisan, P. D. Konstantinova, P. Maupin, G. Mercier, T. A. Semerdjiev, F. Smarandache, H. sunlight, A. P. Tchamova.

The ebook has been introduced in June on the Fusion 2004 convention in Stockholm, Sweden.

A moment quantity approximately new functions and advancements of DSmT (Dezert-Smarandache thought of believable, doubtful, and paradoxist details) may be released subsequent 12 months. anyone is invited to give a contribution papers or chapters for this moment collective booklet. time limit: Fall 2005.

The DST assumes therefore that a refinement exists to describe the fusion problem and is achievable while DSmT does not make such assumption at its starting. The assumption of existence of a refinement process appears to us as a very strong assumption which reduces drastically the domain of applicability of the DST because the frames for most of problems described in terms of natural language manipulating vague/continuous/relative concepts cannot be formally refined at all. Such an assumption is not fundamental and is relaxed in DSmT.

2. If A, B ∈ DΘ , then A ∩ B ∈ DΘ and A ∪ B ∈ DΘ . 3. No other elements belong to DΘ , except those obtained by using rules 1 or 2. The dual (obtained by switching ∪ and ∩ in expressions) of DΘ is itself. There are elements in DΘ which are self-dual (dual to themselves), for example α8 for the case when n = 3 in the example given in the n next section. The cardinality of DΘ is majored by 22 when Card(Θ) = |Θ| = n. The generation of hyper-power set DΘ is closely related with the famous Dedekind problem [4, 3] on enumerating the set of monotone Boolean functions as it will be presented in the sequel with the generation of the elements of DΘ .

E. e. when the frame Θ is changing with time. 16 CHAPTER 1. PRESENTATION OF DSMT These definitions are compatible with the definitions of classical belief functions in the DST framework when DΘ reduces to 2Θ for fusion problems where Shafer’s model M0 (Θ) holds. We still have ∀A ∈ DΘ , Bel(A) ≤ Pl(A). Note that when working with the free DSm model Mf (Θ), one has always Pl(A) = 1 ∀A = ∅ ∈ DΘ which is normal. ) corresponds to the conjunctive consensus of the sources. e. ) : DΘ → [0, 1]. This rule of combination is commutative and associative and can always be used for the fusion of sources involving fuzzy concepts.
