- Abstract:
-
The data-driven extended belief rule-based system uses relational data to generate rules based on the traditional belief rule base. Using this method to build a rule base is simple and effective. However, the rules activated by this method are inconsistent and incomplete, and this method cannot handle none-activated inputs. Therefore, this paper proposes an extended belief rule-based method, based on an improved rule activation rate. This method improves upon the individual matching degree calculation method through gauss kernels, balances the consistency and completeness of activation rules, and solves the problem of non-activation of rules based on the idea of k-nearest neighbors. Finally, this paper selects a nonlinear function fitting experiment and an oil pipeline leak detection experiment to test the efficiency and accuracy of the proposed method. Experimental results showed that the proposed method not only ensures efficiency, but also improves the accuracy of the extended belief rule-based system.
