The Combining Rule of Dempster-Shafer Theory for Correlative Evidence

摘要

This paper puts forward an improvement method for the combining rule of Dempster-Shafer evidence theory based on the correlation between evidences.Different from D-S theory, the correlation coefficient between evidences is introduced. By decreasing the probability evaluation of certainty and increasing the probability evaluation of uncertainty, the effect of correlative evidence to fusion result is reduced, and then we can get the fusion result which is closer to the fact. Finally, an example is provided to show the advantage of this method.
