Based on the analysis of the mechanism of fuzzy reasoning by compositional rule of inference, the principle of how to achieve the same results with interpolation method is presented.

Based on fuzzy entropy rule and sum-squared error rule, a fuzzy learning method was presented. According to this method, BP neural network was used to model the performance of air-conditioning units.

As a nonlinear method, the fuzzy rule-based pattern recognition has good comprehensibility, but has not been applied to the multiple classifier fusion.
