规则的可信度传播是结论可信度值启发式更新过程的重要阶段之一。单纯的min/max算式不能全面反映前题重要性、松弛约束证据以及旁证条件等因素对规则结论可信度值的影响。本文提出了一种能综合体现上述诸因素作用的可信度传播算法,该算法满足不精确推理模型的统一约束条件,并蕴含了传统的可信度传播算式。
The rule of credibility spread is one of the important stages of the heuristic updating process of the conclusion credibility value. The simple min / max formula can not fully reflect the influence of the factors such as the importance of precedent, the evidence of relaxation restraint and the circumstantial evidence on the credibility of rule conclusion. This paper presents a credibility propagation algorithm that can comprehensively reflect the above-mentioned factors. The algorithm satisfies the unified constraints of inaccurate reasoning model and implies the traditional belief propagation algorithm.
