But for a long time, the heavy computational load of maximizing the multivariate, highly non-linear likelihood function prevented it from popular use. In this paper, we introduced Ant Colony Algorithm (ACA) to work with AML for computing the exact solutions to the likelihood function with a guarantee of global convergence. The resulted estimator is called Approximated Maximum Likelihood bearing estimator based on Ant Colony Algorithm (ACA-AML). Simulations show that ACA-AML not only reduces the computational complexity greatly but also maintains the excellent performance of the original AML estimator.","PeriodicalId":119569,"journal":{"name":"2010 International Conference on Web Information Systems and Mining","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126395767","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}

Optimal Linear Method of. Focusing on its high precision, high fidelity, the authors indicate that the truncation error of interpolation model should be considered as the main error in estimating the error of DEM generation method. A new DEM generation method (MADEM) based on Map Algebra is provided. It is in fact a linear interpolation on horizontal projection of the steepest descent line realized by recursive powered Voronoi interpolation between assigned points and lines. Its precision is much better than that of the DEM generation methods basing on linear interpolation on Delaunay Triangulation under the same conditions, and it also has the feature of high fidelity. Having been compared with other methods, the DEM generation method in this paper should be the best linear interpolation method of all.","PeriodicalId":119569,"journal":{"name":"2010 International Conference on Web Information Systems and Mining","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129379341","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 research adopts addition chains tree to produce addition chains and store them into a database,in which the number of child nodes of each node is uncertain until the children of this node in the tree is completed. When we retrieve a number which does not exist in the database in this method, the system will automatically expand the tree to reach it; meanwhile, if the number is already available in the database, we can get the result very quickly without the further data calculation. The favorable results of the theoretical analysis and the experiments demonstrate that the proposed algorithm is more efficient than the other methods.","PeriodicalId":119569,"journal":{"name":"2010 International Conference on Web Information Systems and Mining","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128895759","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}

To achieve this aim, we extend the agent model with the E-institution elements (roles, role relations, scenes etc) and present a language of the agent model (including the semantic and the properties) to show the characteristics of this kind of agents according to the role-playings of the agents.
