专家系统中证据的合成,传播与修正

在专家系统中，由于证据的不确定性和推理规则的不确定性，推理也相应地发生变化，需要对证据进行合成、传播与修正。有许多文献进行了研究［２］，［３］，［４］，但已有的方法大都是针对不同的不确定性推理给出不同的方法。“本文旨在给出不确定性推理中证据合成、传播与修正的一般公式。

The Combination, Propagation and Modification of Evidence In Expert Systems

In expert systems, because of the introduction of the uncertainty of evidence and reasoning rules,the methods for the uncertainty reasoning should include the combination, propagation and modification of evidence. much work has been done on this respect (2], 3], 4]), However,most of the methods only present specific methods according to particular uncertainty reasoning frameworks. The aim of the present paper is to estabesh some general formulas for the combination,propagation and modification of evidence in uncertainty reasoning.
