A Review on Integrating Evolutionary Multiobjective Optimization in Developing Fuzzy Systems
Vipin Khattri, Sandeep Kumar Nayak · 2018
Fuzzy systems are developed to model the information inexactness and uncertainty in the real world problems. The development of fuzzy system can be considered as an optimization task. So Evolutionary Algorithms are well utilized to design fuzzy systems. The fuzzy systems have two strong features that must be considered during the development i.e. interpretability and accuracy. Interpretability is the subjective feature and not easy to quantify and accuracy shows the closeness between the real and modeled systems. These features are contradicting with each other and lead to interpretability-accuracy trade-off. This is basically combined as a multiobjective optimization problem and further it is solved by the multiobjective optimization evolutionary algorithm (MOEA). This is the reviews the approaches developed under these issues. The future of this research line is also discussed.
