As is well known, Dempster-Shafer theory offers an alternative approach to deal with uncertainty reasoning in expert systems and other fields. In this paper, we present two results that relate to the use of the theory. First, we present and analyze four methods to induce uncerioin rules fvlm a training instance set for Dempster-Shafer theory. This is the first attempt to do so, to the best of o...

World Health Organization reports that African Trypanosomiasis affects mostly poor populations living in remote rural areas of Africa that can be fatal if properly not treated. This paper presents Dempster-Shafer Theory for the detection of African trypanosomiasis. Sustainable elimination of African trypanosomiasis as a public-health problem is feasible and requires continuous efforts and innov...

Abstract How to effectively reflect the randomness and reliability of decision information under uncertain circumstances, thereby improve accuracy decision-making in complex scenarios, has become a crucial topic field decision-making. In this article, loss –aversion behavior decision-makers non-compensation between attributes are considered. Furthermore, novel generalized TODIM-ELECTRE II metho...

In social media, trust and distrust among users are important factors in helping users make decisions, dissect information, and receive recommendations. However, the sparsity and imbalance of social relations bring great difficulties and challenges in predicting trust and distrust. Meanwhile, there are numerous inducing factors to determine trust and distrust relations. The relationship among i...

The latest developments in Markov models’ theory and their corresponding computational techniques have opened new rooms for image and signal modeling. In particular, the use of Dempster–Shafer theory of evidence within Markov models has brought some keys to several challenging difficulties that the conventional hidden Markov models cannot handle. These difficulties are concerned mainly with two...

Lightning has a certain degree of potential threat to the safe operation overhead transmission lines. In order make targeted lightning protection arrangements and reduce impact on lines, it is necessary conduct risk assessments This paper proposes failure assessment method for lines based modified Dempster–Shafer theory. First, analyze historical data line, determine factors, use confidence exp...

This paper examines the relationship between Shafer's belief functions and convex sets of probability distributions. Kyburg's (1986) result showed that belief function models form a subset of the class of closed convex probability distributions. This paper emphasizes the importance of Kyburg's result by looking at simple examples involving Bernoulli trials. Furthermore, it is shown that many co...

A sufficient condition is developed for the equality of the plausibility and commonality measures of the Dempster-Shafer belief calculus. When the condition is met, as it is in many applications, an efficient method to calculate relative plausibility is available. In particular, the method can be used to calculate the relative plausibility of atomic hypotheses and, therefore, it can be used to ...

The likelihood and uncertainty of severe rains flooding in the middle basin Yangtze River have grown due to global warming growing urbanization. A flood risk assessment index system is built based on resilience theory assess community a significantly changing environment, with communities serving as primary body manage cities. level Wuhan from 2011 2020 was assessed using Analytic Hierarchical ...
