Inspiration is drawn from a fuzzy neural network that is constructed by fuzzy logic and zeroing neural network (ZNN). Distinct from most sliding mode control approaches, two nonsingular sliding mode surfaces are formulated by employing general ZNN approaches and differentiable predefined-time activation functions. Furthermore, for the compensation of external disturbance, a dynamic adaptive parameter and a fuzzy adaptive parameter are designed in the attitude control law. The fuzzy adaptive parameter, generated by the Takagi–Sugeno fuzzy logic system, is incorporated to enhance the robustness while reducing the chattering phenomena resulting from the discontinuous sign function. Theoretical proofs are provided to demonstrate the predefined-time convergence and robustness of the closed-loop system. Finally, two trajectory tracking examples are offered to validate the convergence, robustness, and low-chattering characteristics of the closed-loop system under the developed ARPTNSMC scheme.","PeriodicalId":13212,"journal":{"name":"IEEE Transactions on Fuzzy Systems","volume":"32 12","pages":"6775-6788"},"PeriodicalIF":10.7,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142759903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enhance the performance of feature selection, regularizers like \u0000<inline-formula><tex-math>${ell _{1}}$</tex-math></inline-formula>\u0000-norm or \u0000<inline-formula><tex-math>${ell _{2,1}}$</tex-math></inline-formula>\u0000-norm are commonly utilized to encourage sparsity. Nonetheless, these traditional regularization techniques encounter certain challenges. When correlations exist among features, the sparsity-driven regularization can unfairly diminish weights of correlated features to zero, thus ignoring the feature correlations and lacking group sparsity properties. While a straightforward combination of \u0000<inline-formula><tex-math>${ell _{1}}$</tex-math></inline-formula>\u0000-norm and \u0000<inline-formula><tex-math>${ell _{2}}$</tex-math></inline-formula>\u0000-norm can uncover feature correlations, it lacks adaptability and effectively balancing sparsity and correlation. To address these challenges, we introduce a novel matrix-based regularization term, called a fuzzy elastic net, in the unsupervised feature selection model. Our model is founded on principal component analysis, a well-established dimensionality reduction technique adept at finding subspaces that retain most information from raw data. The model is enhanced by a fuzzy elastic net, which promotes group or sparsity properties through adaptive parameter tuning. The new regularization term introduces a flexible fuzzy weighted scheme combining the \u0000<inline-formula><tex-math>${ell _{2,2}}$</tex-math></inline-formula>\u0000-norm and \u0000<inline-formula><tex-math>${ell _{2,p}}$</tex-math></inline-formula>\u0000-norm (\u0000<inline-formula><tex-math>$0< pleq 1$</tex-math></inline-formula>\u0000). This approach allows adaptive adjustment based on data characteristics, offering a tunable balance between selecting discriminative features and identifying correlated ones. Consequently, this regularization term equips the model to handle diverse data analysis tasks flexibly, thereby enhancing adaptability and generalization performance. Furthermore, we propose an efficient optimization strategy to solve this model. Extensive experiments conducted on UCI datasets and real-world datasets demonstrate the effectiveness and efficiency of our proposed method.","PeriodicalId":13212,"journal":{"name":"IEEE Transactions on Fuzzy Systems","volume":"32 12","pages":"6878-6890"},"PeriodicalIF":10.7,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142759901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
