基于关联度的决策概率转换方法

针对基本概率赋值转换为决策概率的问题,提出一种新的基于关联度的决策概率转换方法.该方法将单子集命题的基本概率赋值和转换后的决策概率之间的关联度作为评价转换方法的标准,并用其对比例信度转换方法和比例似然度转换方法进行线性组合,得出命题的决策概率.通过算例对比新方法与已有方法,结果表明新方法更加合理有效.

Transformation method of decision-making probability based on correlation degree

To slove the problem in the transformation of basic probability assignment to decision-making probability, this paper proposed a novel transformation method based on correlation degree. The correlation degree between basic probability assignment of singleton proposition and decision-making probability was used to evaluate the transformation method, and the decision-making probability of each proposition was achieved by linear combination, which was the transformation method of decision-making probability based on proportional belief and proportional plausibility. The proposed method was compared to the other usual methods with an example. The experimental result shows that the proposed method is more reasonable and effective.
