基于粗糙集的证据获取与合成方法研究
Research on evidence acquirement and combination method based on rough set
摘要
Abstract
Evidence theory is a powerful tool to deal with uncertain problems.However, the evidence is usually obtained from experts with a high degree of subjectivity, and the importance of different evidences combined is equivalent.A novel method of evidence acquirement and combination based on rough set is proposed.Confidence degrees of evidence are used to calculate approximate conditional probability assignments.Evidence weights are calculated according to the attribute significances and support degrees of evidence.Decisions are gained by using combinational rule to integrate approximate conditional probability assignments.The results show the validity of this method.关键词
