A very computationally-efficient MonteCarlo algorithm for the calculation of Dempster-Shafer belief is described. If Bel is the combination using Dempster’s Rule of belief functions Bel1, . . . ,Belm then, for subset b of the frame Θ, Bel(b) can be calculated in time linear in |Θ| and m (given that the weight of conflict is bounded). The algorithm can also be used to improve the complexity of t...

An evidential reasoning mechanism based on the Dempster-Shafer theory of evidence is introduced. Its performance in real-world image analysis is compared with other mechanisms based on the Bayesian formalism and a simple weight combination method.

Health is very important and valuable for humans, because without good health, every human being will experience difficulties in carrying out their daily activities. Mycetoma disease, also known as fungal infection flesh-eating affects people who live rural or remote areas have limited access to health care medicines. So overcome this problem, we need an expert system that able diagnose mycetom...

Shafer [1] defined weights of evidence and the weight of internal conflict for separable support functions. He also formulated a conjecture, the weight-ofconflict conjecture, which implies that these definitions can be extended in a natural way to all support functions. In this paper I show that the extension to support functions can be carried out whether or not the weight-of-conflict conjectu...

Affective analysis of images in social networks has drawn much attention, and the texts surrounding images are proven to provide valuable semantic meanings about image content, which can hardly be represented by low-level visual features. In this paper, we propose a novel approach for visual affective classification (VAC) task. This approach combines visual representations along with novel text...

How to quantify the uncertain information in the framework of Dempster-Shafer evidence theory is still an open issue. Quite a few uncertainty measures have been proposed in Dempster-Shafer framework, however, the existing studies mainly focus on the mass function itself, the available information represented by the scale of the frame of discernment (FOD) in the body of evidence is ignored. With...

The drawbacks of pure probabilistic methods and of the certainty factor model have led us in recent years to consider alternate approaches. Particularly appealing is the mathematical theory of evidence developed by Arthur Dempster. We are convinced it merits careful study and interpretation in the context of expert systems. This theory was first set forth by Dempster in the 1960s and subsequent...
