查询词典 data delimiter

Uniform random sampling is widely applied to many kinds of algorithms in data mining. It processes uniform distribution data set extremely effectively, but easily loses slight cluster and consequently decreases clustering accuracy, when the processing data set is skew distribution.

随机抽样技术已经广泛应用于数据挖掘的各类算法中，它在处理分布均匀的数据集时非常有效，但在处理分布比较倾斜的数据集时容易丢失小的聚类。

So,the massive data acquired in the period from January to December in 2006 and authorized by CAIDA Skitter project were used to analyze the searched topological data at CAIDA(cooperative association for Internet data analysis) router level,thus describing the characteristics of the distribution of the degree s of nodes at router level.

针对目前对路由层面的Internet拓扑研究较少的问题，基于2006年1月至2006年12月采集的CAIDA Skitter项目授权的海量数据，对CAIDA路由层面拓扑探测数据进行了分析，描述了路由级节点度分布的幂率性。在此基础上计算出了更能体现网络拓扑层次性的各节点的核数，描述了节点核的幂率分布性质，进一步分析了节点核数与度之间的关系。研究表明，对低核节点，其度分布存在着幂率性质
