Genetic tuning of fuzzy rule-based systems integrating linguistic hedges
Jorge Casillas, Óscar Cordón, Francisco Herrera, María José del Jesús · 2002
Tuning fuzzy rule-based systems for linguistic modeling is an interesting and widely developed task. It involves adjusting the membership functions composing the knowledge base. To do that, changing the parameters defining each membership function as using linguistic hedges to slightly modify them may be considered. This paper introduces a genetic tuning process for jointly making these two tuning approaches. The experimental results show that our method obtains accurate linguistic models in both approximation and generalization aspects.
