Most studies on social networks require access to the data, which often contains sensitive information that needs to be anonymized before publication. One of such anonymized approaches is link privacy. A standard technique of link privacy is to probabilistically randomize the destination of a link in the local neighborhood of the source node of link, known as neighborhood randomization technique. In this paper, we propose an algorithm based on neighborhood randomization. Unlike previous studies, the proposed algorithm pays more attention to popular nodes in the social network structure. Given the low number of these nodes and the fact that the links of these nodes are more often threatened, they have been perturbed more than other nodes to preserve the privacy of popular nodes. The algorithm has been evaluated using real life social network data.","PeriodicalId":239692,"journal":{"name":"2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116136924","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}

Three static methods have been evaluated: the linear model, the multilayer perceptron (MLP) and the radial basis function (RBF). For linear case, the selection of appropriate attributes was determined by forward selection and for nonlinear one, the selection was based on the genetic algorithm (GA) result. Parameters of nonlinear models were determined by cross-validation and then well logs were estimated. By comparing estimated and actual logs, RBF has the best performance with least training error. Since well logs contain high frequency content, so localized networks such as RBF has better performance than MLP through the study data set.","PeriodicalId":239692,"journal":{"name":"2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125720782","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}

One of the most important requirements of cloud is employing an efficient method to register and discover services which are befitting consumer needs. A successful search to discover the service requires an efficient service registry. In this paper, an algorithm is introduced for minimizing the number of service registry messages in unstructured peer to peer network cloud platform for execution of which, the genetic algorithm has been used to discover an efficient arrangement of service providers as well as exploiting the breadth first search to discover connective arrangements. The execution is done on different arrangements of service providers the results of which show that the mentioned minimizing algorithm has reached to the most efficient arrangement that leads the least service registry messages.","PeriodicalId":239692,"journal":{"name":"2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131386807","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}

Due to non-linear and time varying dynamic, controlling this vehicle has some special difficulties. Modeling errors that may exist and Uncertainties which associated with the environment firstly evokes that the idea of a robust controller to control the underwater robot. For this purpose, after the linearization of underwater robot model with six degrees of freedom at the optimum operating point, then design H_infinity controller. Furthermore fuzzy logic controller which can works with nonlinear model and unpredictable uncertainty Such as sea currents which influence on autonomous underwater vehicle performance is designed. Finally compare obtained results in fuzzy logic controller with H_infinity robust controller. As shown in simulation results fuzzy logic controller has better performance in the presence of uncertainties in compare with H_infinity robust controller.","PeriodicalId":239692,"journal":{"name":"2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115644386","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}
