A combination rule of evidence theory based on brief max-entropy model
Wang Zhen-jiang · Kongzhi yu juece · 2012
The combination rule of high conflict evidence is one of the important issues in D-S theory since it gives error results that contrary with the instinct.Combining relative theories into D-S theory is an effective way in dealing with the inherent defects of D-S theory.Based on the max-entropy and D-S theory,a basic belief max-entropy assignment function is proposed.Then a model based on max-entropy is obtained by combing Max-entropy with classic D-S theory and the alternative D-S theories,relevant rational formulas are presented.Theoretical analysis and experiments show that the incorporation of the new max-entropy evidence into D-S theory can better process high-conflict information by re-allocating the basic belief value of the non-single focal elements proportionally into the single focal elements.
