Abstract Generalization is very important in Cerebellar Model Articulation Controller (CMAC). If CMAC has good generalization, it will have high precision. In this paper, the principle, structure and learning algorithm of CMAC are described. The relationship between the quantification precision and sampling precision that influences the generalization is discussed theoretically. Simulation results show the correctness of relationship between the quantification and sampling precision, and the conclusion that the quantification precision should be higher than the sampling precision is gotten. Moreover, a new kind of optimization based on pareto genetic algorithm (PGA) about generalization parameter and quantification precision is proposed. Experimental results show the correctness of the new method.
