【摘要】：針對傳統(tǒng)Takagi-Sugeno-Kan(TSK)模糊系統(tǒng)處理大規(guī)模數(shù)據(jù)時間代價較高的問題,提出一種基于概率模型框架的L2型TSK模糊系統(tǒng)建模策略,建立具有處理大規(guī)模數(shù)據(jù)能力的貝葉斯L2型TSK模糊系統(tǒng)(B-TSK-FS).具體地,基于L2型TSK模糊系統(tǒng)的輸出誤差概率化表示,對系統(tǒng)前后件參數(shù)聯(lián)合學(xué)習(xí),提高系統(tǒng)的泛化能力.另外,引入狄利克雷先驗(yàn)分布函數(shù),對模糊隸屬度稀疏化表示,實(shí)現(xiàn)樣本的壓縮,降低運(yùn)算時間.在模擬和真實(shí)數(shù)據(jù)集上的實(shí)驗(yàn)結(jié)果驗(yàn)證了所提出模糊系統(tǒng)的優(yōu)勢.
[Abstract]:In order to solve the problem of high time cost for traditional Takagi-Sugeno-Kanko fuzzy system to deal with large-scale data, a modeling strategy of L2 type TSK fuzzy system based on probabilistic model framework is proposed, and a Bayesian L2 type TSK fuzzy system with large scale data processing capability is established. Specifically, based on the probabilistic representation of the output error of L2 type TSK fuzzy system, the parameters of the front and rear parts of the system are jointly studied to improve the generalization ability of the system. In addition, the prior distribution function of Delikley is introduced to sparse representation of fuzzy membership degree, which can compress the sample and reduce the operation time. Experimental results on simulated and real data sets verify the advantages of the proposed fuzzy system.
