For this purpose, we introduce new adaptive algorithms for the computation of the square root of the inverse covariance matrix Sigma-1/2. Then we construct self-organized networks based on the proposed algorithms and use them for optimal feature extraction from Gaussian data. Convergence proof of the proposed algorithms and networks is given by introducing the related cost function and discussion about its properties. Adaptive nature of the new feature extraction method makes it appropriate for on-line pattern recognition applications. Experimental results using two-class multidimensional Gaussian data demonstrated the effectiveness of the new adaptive feature extraction method.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133268879","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}

A computer model utilizing measured transfer functions from an experimental setup is developed for simulations using real medical equipment noise. An average cancellation of 16 dB was observed.

This representation, known as quasi-linear parameter varying (Quasi-LPV), is useful for control designs based on nonlinear Hinfin approaches. Two nonlinear Hinfin controllers that guarantee induced L2-norm, between input (disturbances) and output signals, bounded by an attenuation level γ are used to control a WMR. These controllers are solved via linear matrix inequalities (LMIs) and algebraic Riccati equation. Experimental results are presented, with a comparative study among these robust control strategies and the standard computed torque, plus proportional-derivative, controller.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117163442","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}
