摘要:

Smets提出了Pignistic概率转换(PPT)作为可转移信念模型(TBM)中的决策层,该模型认为当没有更多信息时,我们必须使用概率质量函数(PMF)做出决策。通过在层次假设空间中引入因果关系,提出了信念进化网络和完全因果函数。基于BEN,我们解释的PPT从信息融合的观点,并提出了一种新的概率转换(PT)方法称为全因果概率转换(FCPT),它具有更好的性能下双准则评估。此外,我们还提出了一种新的基于FCPT的概率融合方法。与Dempster合并规则(DRC)相比,该方法在融合相同证据时具有更合理的结果。

英文摘要:

Smets proposes the Pignistic Probability Transformation (PPT) as the decision layer in the Transferable Belief Model (TBM), which argues when there is no more information, we have to make a decision using a Probability Mass Function (PMF). In this paper, the Belief Evolution Network (BEN) and the full causality function are proposed by introducing causality in Hierarchical Hypothesis Space (HHS). Based on BEN, we interpret the PPT from an information fusion view and propose a new Probability Transformation (PT) method called Full Causality Probability Transformation (FCPT), which has better performance under Bi-Criteria evaluation. Besides, we heuristically propose a new probability fusion method based on FCPT. Compared with Dempster Rule of Combination (DRC), the proposed method has more reasonable result when fusing same evidence.
