Unfortunately, as the volume of dataset gets larger day by day, most of the FIM algorithms in literature become ineffective due to either too huge resource requirement or too much communication cost. In this paper, we propose a balanced parallel FP-Growth algorithm BPFP, based on the PFP algorithm [1], which parallelizes FP-Growth in the MapReduce approach. BPFP adds into PFP load balance feature, which improves parallelization and thereby improves performance. Through empirical study, BPFP outperformed the PFP which uses some simple grouping strategy.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129950976","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 paper presents a Web services selection algorithm of QoS-aware and global multi-objective optimization, termed WSSPEA2. The essence of the proposed algorithm is that the problem of Web services selection based on QoS is transformed into a multi-objective services composition optimization problem with QoS constraints. A strength Pareto evolutionary algorithm (SPEA2) is utilized to produce a set of Pareto-optimal solutions by means of simultaneously optimizing a series of objective functions, that is, minimizing service cost(C) and service time(T) with the constaint of satifying the parameters reputation(RE), reliability(R) and availability(A). And the users can select one from these solutions for their preferences. The results of a series of simulation experiments indicate the feasibility and efficiency of this algorithm.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115623615","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}

Finally, we evaluated the impact of sample size and its distribution on classification accuracy. The train and test ratio of 8:2 was proved to be a better choice for improving land cover classification. The distribution of samples influenced classification results, with a standard deviation of 0.81 to overall accuracy and 0.01 to Kappa coefficient. The overall accuracy of resultant classification map was 96.45 with Kappa coefficient of 95.8%.

However perfect channel knowledge is required, which leads to large feedback amount of channel state information (CSI). In this paper, the uplink scenario of multi-relay OFDM cooperative networks with subcarrier mapping scheme is considered. An opportunistic relaying strategy with limit feedback CSI is proposed. The transmission scheme, which is based on instantaneous channel quality, is selected to offer maximum the end-to-end system capacity.

This paper proposed the mathematical model and the quantitative research methods on the variability in the task execution-time. On the modern complex digital signal processing platform, the task execution-time probability density can be approximated as normal distribution. The mean-variance of execution-time, which can be an indicator to measure the degree of variability in the task execution-time, indicates the dispersion of all execution-time samples from the mean execution-time. This paper analyzed the variability in the task execution-time of the Godson 2E processor-based digital demodulation system. Experiments show that the interaction between different tasks will be reduced by task scheduling. Task scheduling is an effective method to significantly reduce the mean-variance of execution-time, and is an effective method to reduce the degree of variability in the task execution-time.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115455378","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}

An efficient Media Access Control (MAC) protocol is important for future home private WDM optical fiber network, which provides high data rate services to large amount of device. The advantages of multi-channels Aloha and Slotted Aloha scheme are simple structure and low cost. Moreover, optical fiber provides large amount of bandwidth which is far larger than device requirement. In this article, Aloha and Slotted Aloha schemes are proposed for home private optical fiber bus network. Reasons are provided for choosing bus topology instead of star topology and against Carrier Sense Multiple Access (CSMA) as the MAC scheme.
