A New Method to Determine BPA in Evidence Theory

Wen Jiang, Yong Deng, JinYe Peng

Abstract


Dempster Shafer theory of evidence has been widely used in many data fusion application systems. However, how to determine basic probability assignment, which is the main and the first step in evidence theory, is still an open issue. In this paper, based on the distance measure between the sample data under test and the model of attribute of species, a new method to obtain BPA is proposed. A numerical example is used to illustrate the efficiency of the proposed method.
