Contribution of evidence-similarity to target classification

Abstract

To resolve the target classification problem under the condition of interference, the paper presents a target classification method based on the evidence-similarity. Because the results of Dempster-Shafer Theory (DST) and Dezert-Smarandache Theory (DSmT) are used in different conflict condition. In the low conflict situation, the classification by DST has good effect, but the classification by DSmT introduces the focal element, which increase the amount of computation greatly. In the high conflict situation, DSmT can effectively tackle the problem that the contradiction focal element can not be fused in DST, and avoid the DST classification appearing counterintuitive conclusions. Therefore, the two kinds of classification theories are combined by the similarity of evidence in the paper. Experiment results show that the method can effectively improve the accuracy of the target classification under different conflict condition.
