Determining interval basic probability assignment based on statistical information

Evidence theory can express and process uncertain and non-precision information well, so it is widely used in the related fields of information fusion. How to determine the basic probability assignment is one of the most difficult problems of the evidence theory. Traditional single basic probability assignment is difficult to measure some fuzzy information, but the interval basic probability assignment can solve the problem better. Therefore, this paper proposes a method to determine the interval basic probability assignment based on confused matrix, this method measures the uncertainty of the statistic information by interval probability, and converts the interval combination results to single probability by the method of interval probability transform, then do the decision by the single probability. The simulation results indicate that this method is reasonable and effective.
