Fault diagnosis of machines based on D–S evidence theory. Part 1: D–S evidence theory and its improvement

Pattern Recognition Letters, 2006
In this paper, conventional D-S evidence theory is improved through the introduction of fuzzy membership function, importance index, and conflict factor in order to address the issues of evidence sufficiency, evidence importance, and conflicting evidences in the practical application of D-S evidence theory.

Fault Diagnosis of Generator Based on D-S Evidence Theory

2008 Eighth International Conference on Intelligent Systems Design and Applications, 2008
It is difficult to identify the fault type with the signal gathered from the sensors. In this paper, a new fusion algorithm based on the Dempster-Shafer theory of evidence and neural networks is brought forward. This method combines the advantages of D-S evidence theory and the BP neural network. Neural networks are used to pretreated the data gathered

Application of D-S evidence theory in equipment fault diagnosis

2011 Seventh International Conference on Natural Computation, 2011
For the situation that the changes of the state parameters are uncertain in the equipment working process, this would create difficulties for equipment fault diagnosis. In this paper, we utilize the D-S (Dempster-Shafer) evidence theory data fusion algorithm for data processing.

Grid Map Building Based on D-S Evidence Theory

2009 Fifth International Conference on Natural Computation, 2009
A method of constructing a grid map using ultrasonic sensors based on Dempster-Shafer evidence theory (D-S evidence theory) is proposed with respect to the problem of unstructured unknown environment mapping. Mobile robot explores environment with ultrasonic sensors; D-S evidence theory is used to fuse multi-sensor information; The problem that D-S ...

Fact Reasoning with Reliable D-S Evidence Theory

2009 Third International Symposium on Intelligent Information Technology Application, 2009
This paper introduced a reasoning method based on D-S evidence theory for inferring the facts of a law case. For repairing shortage of classic D-S theory, the reliability factor D and correlative coefficient r are introduced to decrease the influence of uncertain evidence and correlative evidence on reasoning conclusion.

The ship discrimination based on D-S evidence theory

2012 IEEE 11th International Conference on Signal Processing, 2012
The paper presents a new method of ship discrimination based on the theory of DS evidence. What's more, based on the analysis of the ship and the common false alarm scattering mechanism differences, the effective polarization characteristics are extracted, and the basic probability assignment method based on the polarization characteristics are ...

Reliability assessment based on D-S evidence theory

2009 8th International Conference on Reliability, Maintainability and Safety, 2009
For many high-reliability products, reliability assessment relying on the tests has become unrealistic, but expert experience shows its advantage to the above problem. In order to resolve the problem that how to fuse the expert experience, we convert the expert experience into the reliability probability density distribution, determine the knowledge ...

Modified combination rule of D-S evidence theory

2010 2nd IEEE International Conference on Information Management and Engineering, 2010
For solving information fusion problem of inequality important information in integrated target recognition the concept of evidence weight is introduced based on D-S reasoning. For transformation of each evidence according to its weight difference the evidence synthesis is completed using tradition method in integrated target recognition of different ...

An Improved Evidence Combination Method of D-S Theory

2016 International Symposium on Computer, Consumer and Control (IS3C), 2016
Dempster-Shafer evidence theory provides a useful computational scheme for integrating uncertain information from multiple sources. However, the combination result can be paradoxical when the evidences seriously conflict with each other. In this paper, we present an improved D-S algorithm which verifies the weights of conflicting evidences. Firstly, we

Matting image based on D-S evidence theory

IEEE Conference Anthology, 2013
This paper presents a new method for the matting problem of color image, which is based on the ideology of image matting proposed by Thomas Porter and Tom Duff and the algorithm of D-S evidence theory. Firstly, the given image must be marked as many approaches. The difference from other methods is that the boundary of foreground called uncertain region
