The idea is based on the analysis of the optimizing hyper-plane and support vectors induced by an RBF kernel. We use the conformal transformation and Riemannian metric to modify this RBF kernel, and reconstruct a new SVM with the modified kernel. The later SVM is shown to be superior to the traditional SVM classifier. Experimental results show that this method can improve the accuracy of the class with less training data under a high total accuracy.","PeriodicalId":110076,"journal":{"name":"2007 Chinese Control Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123705509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The time delay operator is addressed and used to describe the nonlinear time delay systems. Then, the necessary and sufficient conditions for ODDP are achieved by applying extension Lie derivative and extension Lie bracket, and the input-output linearization of decoupling subsystem is also realized at the same time. Furthermore, two decoupling feedback control algorithms under the disturbance is available and unavailable for measurements are discussed. At last, the effectiveness of algorithms is verified by an illustration.","PeriodicalId":110076,"journal":{"name":"2007 Chinese Control Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125319023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sufficient conditions for the convergence to a consensus are obtained based on the frequency-domain analysis and matrix theory. The conditions depend on each agent's self-delay, the weights of the edges to each agent's neighbors, and the interconnection topology of the network. Under the proposed protocol, introducing self-delay can speed up the convergence rate for the system with communication delays. Moreover, the communication delays do not influence the convergence; they prolong the converging time instead. Simulation results illustrate the correctness of the results.","PeriodicalId":110076,"journal":{"name":"2007 Chinese Control Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125398846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
