Multi-ultrasonic sensor fusion for autonomous mobile robots

Zou Yi, Yeong K. Ho, Chin Seng Chua, Xiao Wei Zhou, Belur V. Dasarathy
2000 Sensor Fusion: Architectures, Algorithms, and Applications IV  
Dempster's rule of combination is used to fuse the sensor data to obtain the map defined on a 2D evidence grid.  ...  In this paper, we examine the application of evidential method for data integration using the specially designed sensor model to overcome the problem.  ...  Dempster-Shafer's evidence theory has advantages over Bayesian theory in this aspect since it is able to provide evidence for both singletons and subsets so it can clearly distinguish between ignorance  ...

The combination of belief: When and how fast?

Nic wilson
1992 International Journal of Approximate Reasoning  
The cornerstone of Dempster-Shafer therory is Dempster's rule and to use the theory it is essential to know when the rule is justified. This paper discusses, and attempts to clarify, this issue.  ...  A Monte-Carlo algorithm is described which can be used to greatly improve the complexity of the calculation of combined belief.  ...  ACKNOWLEDGMENTS Thanks to Mike Clarke, Serai]n Moral, Judea Pearl, and Philippe Smets for many useful and enjoyable discussions.

On The Validity Of Dempster-Shafer Theory

Jean Dezert, Pei Wang, Albena Tchamova
2015 Zenodo  
We challenge the validity of Dempster-Shafer Theory by using an emblematic example to show that DS rule produces counter-intuitive result.  ...  is not applicable to evidences combination in general, but only to a certain type situations which still need to be clearly identified.  ...  Before going further in our discussion, let us recall two of Shafer's statements about DST: The burden of our theory is that this rule [Dempster's rule of combination] corresponds to the pooling of evidence  ...

We analyzed an area of 50 km² in Rhineland Palatinate (Germany) near a Celtic oppidum by use of Dempster-Shafer's theory of evidence for predicting spatial probability distribution of archaeological sites  ...  One possibility to cope with such uncertainties is utilization of probability based approaches like Bayes Theorem or Dempster-Shafer-Theory.  ...  Dempster-Shafer's Theory of Uncertainty The Dempster-Shafer theory (Dempster, 1968 , Shafer, 1976 ) is a mathematical theory, which uses evidences instead of probabilities for modelling uncertainty.  ...

Basic Formal Properties of A Relational Model of The Mathematical Theory of Evidence [article]

Mieczysław A. Kłopotek, Sławomir T. Wierzchoń
2017 arXiv   pre-print
It is demonstrated that under the interpretation The Dempster rule of evidence combination corresponds to the join operator of the relational database theory.  ...  We demonstrated this property for Dempster rule of combination, marginalization, Shafer's conditioning, independent variables, Shenoy's notion of conditional independence of variables.  ...  The complexity of combination of evidence according to the Dempster rule in [23] gave an impulse for search of a simpler way to accomplish it.  ...

A mobility prediction architecture based on contextual knowledge and spatial conceptual maps

N. Samaan, A. Karmouch
2005 IEEE Transactions on Mobile Computing  
These groups are then refined to predict the user's future location when evidence accumulates using the Dempster rule of combination.  ...  Using concepts of evidential reasoning of Dempster-Shafer's theory, the user's navigation behavior is captured by gathering pieces of evidence concerning different groups of candidate future locations.  ...  Evidence Combination Dempster-Shafer's theory provides a means for combining beliefs from distinct sources, known as the Dempster-Shafer rule of combination.  ...

Using Dempster-Shafer's Evidence Theory for Query Expansion Based on Freebase Knowledge [chapter]

Dazhao Pan, Peng Zhang, Jingfei Li, Dawei Song, Ji-Rong Wen, Yuexian Hou, Bin Hu, Yuan Jia, Anne De Roeck
2013 Lecture Notes in Computer Science  
We propose a novel method, based on the well-principled Dempster-Shafer's (D-S) evidence theory, to measure the certainty of expansion terms from the Freebase structure.  ...  The expanded query model is then combined with a state of the art statistical query expansion model -the Relevance Model (RM3).  ...  Then it is key to fuse the relevant information from different aspects. In this paper, we propose to solve the fusion problem by using the Dempster-Shafer's (D-S) evidence theory [23] .  ...

A Belief Model of Query Difficulty That Uses Subjective Logic [chapter]

Christina Lioma, Roi Blanco, Raquel Mochales Palau, Marie-Francine Moens
2009 Lecture Notes in Computer Science  
This allows us to define a belief model and a set of operators for combining evidence of query difficulty.  ...  An application of this model with semantic and pragmatic evidence about 150 TREC queries illustrates the potential flexibility of this framework in expressing and combining evidence.  ...  Instead, Dempster-Shafer's belief theory suggests assigning a socalled belief mass to the whole event space.  ...
