A Fast Matching Fuzzy Inference Method Based on Self-learning Mechanism

Abstract

The invention relates to a self-learning mechanism-base fast matching fuzzy reasoning method. The method includes the following steps that: a Gaussian membership degree function method is adopted to construct parameter fuzzification information; a fuzzy rule base is established; external parameters are fuzzificated, so that a fact item can be obtained; the fact item is matched with rules in the fuzzy rule base by adopting a rete algorithm, so that a fuzzy reasoning result can be obtained; the fuzzy reasoning result is subjected to defuzzification, so that a final reasoning result can be obtained; and a sample set is constructed according to the final reasoning result and an actual feedback result, and rule strength self-learning correction is carried out based on the sample set. According to the self-learning mechanism-base fast matching fuzzy reasoning method of the invention, the rete algorithm is adopted, so that the efficiency of fuzzy reasoning can be improved, and the fuzzy reasoning method can be applied to the engineering field with high real-time requirements.

Problems solved by technology

[0004] Most of the current fuzzy reasoning technology adopts the forward reasoning method. When the number of knowledge rules is large, explosive combination of knowledge is easy to occur, resulting in low efficiency of pattern matching. On the other hand, the construction of fuzzy knowledge base in fuzzy reasoning technology mainly relies on Due to the experience of experts, in the process of using the fuzzy reasoning system, it mainly relies on experts to maintain the knowledge base, and lacks a self-learning correction mechanism based on reasoning result samples
