Model‐based object recognition using basic probability assignment

Systems and Computers in Japan, 1995
AbstractA method of object recognition is proposed based on Dempster‐Shafer theory (DS theory), which can treat the ambiguity of image data. A model based object recognition technique based on an aspect imaging method will also be proposed. The aspect imaging method recognizes a similar aspect object by comparing an input image with an aspect image of ...

Determining Basic Probability Assignment for Efficient Data Fusion

Advanced Science and Technology Letters, 2014
The Basic Probability Assignment should basically include the un- certainty and obscurity of the context of the real world to recognize and reduce the uncertainty in the result of the arithmetic operation. This study proposed calculation of the BPA by getting a clue from a policy that recognizes at a cer- tain time interval and reports changes worth ...

Discriminating Event Information for Calculation of Basic Probability Assignment

International Journal of Smart Home, 2013
This study proposed a novel way to calculate Basic Probability Assignment(BPA), which is crucial in the data fusion. The study mapped sensing signal with a linear discriminant function analysis and assessed the sizes with time. This was beneficial to get a clue for context inference with using the Dempster-Shafer Theory and to determine BPA based on ...

Determination of Basic Probability Assignment Based on Recognition Sequence

Advanced Materials Research, 2014
In some practical application of target recognition with sensors, the sensors will give the recognition sequence of targets, which is more detailed than the single recognition result. How to properly construct the basic probability assignment by the recognition sequence becomes the key to successful application of evidence theory.

Entropy measures associated with a fuzzy basic probability assignment

Proceedings of 6th International Fuzzy Systems Conference, 2002
We consider a basic probability assignment whose focal elements are fuzzy subsets (called FBPA for short). FBPA offers an appropriate scheme in order to generalize several known measures of entropy. In addition, we provide a general formulation which also contains new measures of entropy.

A non-parametric method to determine basic probability assignment for classification problems

Applied Intelligence, 2014
As an important tool for knowledge representation and decision-making under uncertainty, Dempster-Shafer evidence theory (D-S theory) has been used in many fields. The application of D-S theory is critically dependent on the availability of the basic probability assignment (BPA). The determination of BPA is still an open issue.

Nonspecificity Degrees of Basic Probability Assignments

2001
As we have already defined, in the case of a finite basic space S, basic probability assignment (BPA) on S is a probability distribution on the power-set P(S) (set of all subsets of S). In this chapter we shall define and investigate the nonspecificity degree of a BPA given by the normalized expected value of the size (cardinality) of subsets of S with

A New Method to Determine Basic Probability Assignment Based on Interval Number

2019 Computing, Communications and IoT Applications (ComComAp), 2019
Dempster-Shafer evidence theory(D-S theory) is a widely used method in information fusion fields. The significant step in applying D-S theory is to determine the basic probability assignment(BPA). But how to determine BPA appropriately is still a problem to be solved.

Combining Basic Probability Assignments for Fuzzy Focal Elements

2008
The Dempster-Shafer theory is convenient for implementation in models of medical diagnosis as it neglects dependence of symptoms. Yet, combination of two basic probability assignments that is defined in the theory is often criticized. The paper shows opportunities of combining that are created when the Dempster-Shafer theory is extended for fuzzy focal

Determination of Generalized Basic Probability Assignment Based on Interval Numbers

Applied Mechanics and Materials, 2014
On the basis of the determination of basic probability assignment based on interval numbers, and combine the generalized evidence theory in the open world, the paper proposed an approach to determine generalized basic probability assignment based on the interval number, which offered a new idea of the determination of generalized basic probability ...
