| Abstract: | A subspace-partition based fuzzy system model(SPFS) and an adaptive model identification algorithm are proposed to solve the rule number's explosion problem.Genetic algorithm is employed to optimize subspace-partition,reduce the maximal identification error in subspaces, and partition the discourse universe on principle of consistency and completion.The relative optimum model identification result is thus achieved.The effectiveness of SPFS is proved theoretically and experimentally.The proposed SPFS model is helpful in relieving the rule number's explosion problem. |
