摘要 目前基于相似关系的近似推理方法 (SBAR)对相似关系的理解并不一致 ,在推理过程中未能考虑相异关系的影响。提出了一种基于相似关系的广义近似推理方法(GSBAR) ,并详细论述了 GSBAR的推理流程以及其中的相似关系函数、相似关系调整函数、相似关系合成函数和推理转换函数的性质 ;进而证明了该方法的逼近能力 ;同时给出了 GSBAR的一个示例。结果表明 ,GSBAR严格遵照相似关系定义 ,综合考虑相似关系和相异关系 ,推理过程直观简便 。 Current similarity based approximate reasoning methods (SBARs) have various views on similarity relations and neglect the effect of dissimilarity relations. A general SBAR (GSBAR) was developed which included the modifying function, the synthesizing function, and the result transforming function of similarity relations. The approximation ability of GSBAR was proved and an illustrative example was given. The result shows that GSBAR includes the definition of similarity relations and considers both similarity relations and dissimilarity relations.
