The classes are learned by the algorithm using the information contained by samples randomly generated from them. The learning process is based on the set of class skeletons, where the class skeleton is represented by the independent axes estimated from data. Basically, for each new sample, the recognition algorithm classifies it in the class whose skeleton is the \"nearest\" to this example. Comparative analysis is performed and experimentally derived conclusions concerning the performance of the proposed method are reported in the final section of the paper for signals recognition applications.","PeriodicalId":269090,"journal":{"name":"2008 The Second International Conference on Advanced Engineering Computing and Applications in Sciences","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121058334","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 fundamental idea underlying this architecture is the use of a hierarchical communications structure called \"logical namespace tree\" and a structured set of control processes interconnected, called \"logical sensors graph\". This architecture is named frame sensor adapter control (FSA-Ctrl). The aim of FSA-Ctrl is to provide a simple interface to specify the control actions and ensure a communication with some specified QoS parameters restrictions. In this architecture both systems, communication and control, manages the QoS policies. The communication system is based on the data distribution service (DDS), a standard proposed by object management group (OMG). Control system is derived from the sensor Web enablement (SWE) model proposed by open geospatial consortium (OGC). The system introduced in this paper is focused on the use of QoS parameters of the distributed systems components to manage the information redundancy.","PeriodicalId":269090,"journal":{"name":"2008 The Second International Conference on Advanced Engineering Computing and Applications in Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129357678","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 other view is that it is a set of standards and tools that help build better Web applications. Since the latter is probably more realistic at the moment, it means that a lot of software has to be developed before we start actually seeing the semantic Web in widespread use.Many developers would be needed for the task and unless we \"win their hearts and minds\", they are likely to obstruct rather than support the semantic Web idea. And from the average developer's point of view, there is not much to like on today's RDF query languages, especially when compared with relational algebra and SQL. Besides the fact that they are built on different principles, none of the languages we are aware of has a property that has served SQL so well - they are not closed.","PeriodicalId":269090,"journal":{"name":"2008 The Second International Conference on Advanced Engineering Computing and Applications in Sciences","volume":"45 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134530898","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}

This task is referred to as function approximation or as generalization. One way to solve the problem is to regress a family of parameterized functions so as to make it fit at best the observed samples. Yet, usually batch methods are used and parameterization is habitually linear. Moreover, very few approaches try to quantify uncertainty reduction occurring when acquiring more samples (thus more information), which can be quite useful depending on the application. In this paper we propose a sparse nonlinear Bayesian online kernel regression. Sparsity is achieved in a preprocessing step by using a dictionary method. The nonlinear Bayesian kernel regression can therefore be considered as achieved online by a Sigma Point Kalman filter. First experiments on a cardinal sine regression show that our approach is promising.","PeriodicalId":269090,"journal":{"name":"2008 The Second International Conference on Advanced Engineering Computing and Applications in Sciences","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130103454","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 location area partitioning is a strategy of location management that tries to minimize the involved costs. In this paper we present a new approach based on differential evolution algorithm applied to the location area partitioning, as a cost optimization problem. We use realistic dat for generating the test networks. This work has the objective of defining the best values to the differential evolution (DE) parameters and setting the DE scheme, which allows us to obtain better results when compared to classical strategies and the other authors' results. The best solution is obtained after the development of four distinct experiments, each one applied to one of the differential evolution parameters. The final results obtained by this approach are very good.","PeriodicalId":269090,"journal":{"name":"2008 The Second International Conference on Advanced Engineering Computing and Applications in Sciences","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122239434","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}
