QUALITATIVE INFLUENCE DIAGRAMS WITH WEIGHTS
摘要
Abstract
Qualitative influence diagrams (QIDs) are the qualitative abstraction of influence diagrams (Ids) with precise probabilities and utilities. In a QID.the influences between nodes are expressed by the qualitative symbols which simplify uncertain knowledge representation, ease influence graphs modeling and accelerate uncertain knowledge reasoning. However, during the abstraction process, qualitative influence graphs lose partial information, resulting in ambiguous evaluation results which impede the extensive application of QIDs. QIDs are extended by attaching a numerical weight to each qualitative influence of QIDs so that the ambiguous evaluation results can be avoided by comparing corresponding weights. Therefore, the application of QIDs will be broadened.关键词
