查询词典 cluster

METHODS: By cluster sampling, 214 cadets from a military academy were investigated with Modified Big Five Personality Scale and selfdesigned decisionmaking scale. The cadets were randomly divided into 2 groups. After noneffective questionnaires were eliminated, the first group (n=110) were in a positive framing and the second group (n=104) in a negative framing. A chisquare test was used to analyze the results of program chosen and t test was used to determine the relationship between personality dimension and risky choice.

采用自编决策问题问卷和大五人格量表中国修订版，以整群抽样的方法，抽取某军校大学生220人为研究对象，随机分为两组，剔除无效问卷后，正面框架组(n=110)，负面框架组(n=104)，对两组间被试的方案选择进行χ2检验，方案选择与人格特征的关系进行t检验。

That is to utilize general MPI programming environment, program on the NHBL parallel computational model, analyze and predicate the running cost of program by using the cost function of this model, and analyze the scalability of program by using the time-scale scalability metric. Finally, we analyze the numeric algorithm example---matrix multiplication and the nonnumeric algorithm example---PSRS sorting on Dawning-1000 MPP and NHPCC-cluster NOW system by using the integrative method.

提出了将并行计算模型、算法、编程进行一体化的研究的方法，即利用通用的标准的MPI编程环境，将编程建立在NHBL并行计算模型上，并且利用该并行计算模型的评价函数进行分析、预测程序的运行代价，再利用时间比例的可扩放性分析方法来分析程序的可扩放性性能；最后我们用PSRS排序算法和矩阵乘法这两个典型的数值和非数值的算法，在曙光-1000并行机和NHPCC-Cluster工作站集群上进行了一体化的分析。

Secondly, the relevance feedback approach requires relevant documents to be similar to each other. That is, they should cluster. Ideally, the term distribution in all relevant documents will be similar to that in the documents marked by the users, while the term distribution in all nonrelevant documents will be different from those in relevant documents. Things will work well if all relevant documents are tightly clustered around a single prototype, or, at least, if there are different prototypes, if the relevant documents have significant vocabulary overlap, while similarities between relevant and nonrelevant documents are small.

第二，相关反馈方法需要相关文档之间相似，即它们可以聚类，理想地，所有相关文档 term 分布应该相似，相关档即用户标记的文档，同时不相关文档应该与相关文档的 term 分布不同，如果所有的相关文档都很紧凑地聚在一个单一的中心点，或至少有不同的中心点，如果相关文档有明显的词汇重复，同时相关与不相关文档相似性比较小，它才是可行的。

According to theoretical analysis, it is convergent and has good convergence if the coefficient matrix is a nonsingular matrix. Moreover, examples have been implemented on HP rx2600 cluster, and the data verify that the numerical results of this algorithm coincide with its theoretics.

在理论上，算法只要系数矩阵A是非奇异矩阵就能够收敛，而且有较好的并行性，在HPrx2600集群上进行数值试验，验证了算法的计算结果与理论相一致。

In the early age,the cluster is managed by command line,therefore,some problems exist,such as imperfect functions,single structure,poor usability and nonsupport remote management etc.

由于集群具有性价比高和可扩展性好等优点，因此在并行处理领域中得到了广泛应用。
