Many applications generate data streams where online analysis needs are essential. In this context, pattern mining is a complex task because it requires access to all data observations. To overcome this problem, the state-of-the-art methods maintain a data sample or a compact data structure ...
in some applications—queries with relatively low selectivity,outlier detection in large multidimensional data sets,and clustering over data streams with skewed Zipf distribution,the importance of need for using biased sampling methods in these scenarios is fully dissertated.In addition to listing ...

Stream sampling is the process of collecting a representative sample of the elements of a data stream. The sample is usually much smaller than the entire stream, but can be designed to retain many important characteristics of the stream, and can be used to estimate many important aggregates on...

1.After discussing the limitation of these existing methods,a viewpoint that the stub-network instead of the IP address should be taken as the sampling granularity was put forward,and a self-contained destination selection method that was termed all stub-networks coverage and two-step random selec...
