However, the constructed filter banks for MCFBS are with irrational coefficients, which bring great obstacles to implement integer transform. In this work, anew class of M-channel filter banks is firstly constructed and then several integer M-channel filter banks (IMFB) derived from this class are proposed for MCFBS. Experimental results show that IMFB can save about 61% of encoding time per frame, with nearly negligible loss of peak signal-to-noise(PSNR) value.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124646820","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}

However,existing top-k query consumes much bandwidth. Motivated by user’s goal to identify one or a few relevant data behind top-k query, it is attractive to use approximate top-k query algorithms to reduce the bandwidth usage. In this paper,we propose a three-phase approximate algorithm (TPAA),which is based on determining the value difference of the same object in different nodes. TPAA precuts the object whose values have big difference in different nodes. By precutting the illegitimate objects with a high probability,TPAA can reduce bandwidth consumption with high precision in some cases. It also supports probabilistic pruning of candidates, considerably reducing bandwidth usage at the expense of a small loss in precision of the top-k results.Furthermore, by performance evaluations using both theoretical analysis and computer simulations, we show that the proposed algorithm can reduce the bandwidth usage compared with existing probabilistic algorithms.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129160437","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}

There may be hundreds or thousands of data sources providing data of relevance to a particular domain on the web, So a primary challenge to large-scale deep web data integration is to determine in what order to user integrate candidate data sources. In this paper, we develop a most-benefit approach (MBA) for ordering candidate data sources for user integration. At the core of this approach is a utility function that quantifies the utility of a given the state of integration system; thus, we devise a utility function for integration system based on query result number. We show in practice how to efficiently apply MBA in concert with this utility function to order data sources. A detailed experimental evaluation on real datasets shows that the ordering of data sources produced by this MBA-based yields a integration system with a significantly higher utility than a wide range of other ordering strategies.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131568671","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}
