The Dempster-Shafer “theory of evidence” encompasses and extends the Bayes Theorem-based decision making machinery. Dempster-Shafer’s innovation is the introduction of lower and upper bounds, designated “belief” and “plausibility”, that are attached to probability estimates. The Dempster-Shafer algebra provides for propagation of and reasoning about these quantities according to an algebra whos...

This paper presents a supervised classi®cation model integrating fuzzy reasoning and Dempster±Shafer propagation of evidence has been built on top of connectionist techniques to address classi®cation tasks in which vagueness and ambiguity coexist. The salient aspect of the approach is the integration within a neuro-fuzzy system of knowledge structures and inferences for evidential reasoning bas...

Cognitive radio (CR) is a promising technology that brings about remarkable improvement in spectrum utilization. To tackle the hidden terminal problem, cooperative spectrum sensing (CSS) which benefits from the spatial diversity has been studied extensively. Since CSS is vulnerable to the attacks initiated by malicious secondary users (SUs), several secure CSS schemes based on Dempster-Shafer t...

In the current versions of the Dempster-Shafer theory, the only essential restriction on the validity of the rule of combination is that the sources of evidence must be statistically independent. Under this assumption, it is permissible to apply the Dempster-Shafer . rule to two or more distinct probability distributions. An essential step in the Dempster-Shafer rule of combination of evidence ...

The initial work introducing Dempster-Shafer (D-S) theory is found in Dempster (1967) and Shafer (1976). Since its introduction the very name causes confusion, a more general term often used is belief functions (both used intermittently here). Nguyen (1978) points out, soon after its introduction, that the rudiments of D-S theory can be considered through distributions of random sets. More furt...

Kucing merupakan salah satu hewan yang banyak dipelihara oleh masyarakat. Penyakit kulit pada kucing seringkali membuat pemiliknya merasa bingung dan terkendala dalam diagnosa penyakit dipelihara. Butuh perawatan lebih untuk menjaga kesehatan perlunya pemahaman bagi pemilik mengetahui cara menangani apabila terserang kulit. Dengan adanya sistem pakar dapat diketahui apa sedang dialami tersebut ...

The weighted average is an efficient way to address conflicting evidence combination in the Dempster-Shafer theory. However, it open issue how determine weights reasonably. Although many traditional solutions based on distance or entropy have been put forward, are determined with a single aspect, and no comprehensive consideration of other useful information affects weights. Thus, does not ensu...

We present a Gibbs sampler for the Dempster–Shafer (DS) approach to statistical inference categorical distributions. The DS framework extends Bayesian approach, allows in particular use...
