- 摘要:
- 为避免模糊系统建模和估计领域的"维数灾难",将TSK(Takagi-Sugeno-Kang)模糊系统建模转换为一个分块稀疏表示问题,提出FCA稀疏TSK模糊系统(FCA-sparse TSK)。首先运用模糊聚类算法(FCA)对样本特征进行化简,并产生模糊系统字典;再利用存在于TSK模糊系统中的分块结构信息,选取重要的模糊规则并对所选模糊规则的后件参数进行估计。该系统同时对模糊规则及模糊规则数进行化简,在合成数据集和真实数据集上都表现出较好的性能。
- Abstract:
- In order to solve the curse of dimensionality existing in fuzzy system identification and approximation, this paper proposes the FCA-sparseTSK fuzzy system by casting the Takagi-Sugeno-Kang(TSK ) fuzzy system identification into a block sparse representation problem. First, FCA-sparseTSK fuzzy system uses the fuzzy clustering algorithm (FCA) to simplify sample features and generate fuzzy system dictionary. Then selects main important fuzzy rules and estimate the fuzzy rule’s consequent parameter vector by taking into account the block-structured information that exists in the TSK fuzzy model. The FCA-sparseTSK fuzzy system simplifies the fuzzy rules and the number of fuzzy rules at the same time and shows good performance in artificial datasets and real-world datasets.
