Abstract:

In order to obtain the accurate structural parameters of fuzzy rules, a disjunctive cloud fuzzy belief rules based recognition method with adaptive parameters is proposed. In order to complete the adaptive division of fuzzy domain, a double threshold detection method based on frequency statistics and inclusion degree separately are proposed. Cloud model is used as fuzzy set, of which by changing entropy coefficient and super entropy coefficient to adjust the shape of fuzzy set, and the connection of premise attributes is set as disjunctive logic relation. The basic probability assignment of conflict evidence is improved, and a programming model is built to optimize the rule weight and attribute weight. The experimental results show that compared with other methods, the correct recognition rate of our method is improved by 5%~15%, and the rules are more interpretable.

Key words: adaptive parameters, cloud fuzzy, belief rule, recognition
