D-S Evidence Belief Calculation

In this article, we will explore in detail how to calculate belief based on D-S evidence theory. This process involves collecting relevant evidence, combining the evidence using Dempster's rule of combination, and finally computing the corresponding belief measure. First, we need to ensure that the collected evidence is reliable, valid, and relevant to the problem under investigation. Then, we apply the combination rules from D-S evidence theory to merge all evidence, which typically involves implementing functions to handle mass functions and resolve conflicts between evidence sources. The combination algorithm requires careful management of conflicting evidence through normalization procedures. Finally, we calculate the belief measure using appropriate formulas, which can be implemented through probability assignment functions that map evidence to belief values over subsets of the frame of discernment. This enables comprehensive and accurate analysis of the problem through quantitative belief quantification.
