Many real-world applications involve multi-label data streams, so effective concept drift detection methods should be able to consider the unique properties of multi-label stream data, such as label dependence. To deal with these challenges, we proposed an efficient and effective method to detect concept drift based on label grouping and entropy for multi-label data. Two methods are proposed to group...
The evolution of Internet topology is not always smooth but sometimes with unusual sudden changes. Consequently, identifying certain patterns of the unusual topology evolution is critical for Internet topology modeling and simulation. We analyze IPv6 Internet topology evolution in IP-level graph to demonstrate how it changes in uncommon ways to restructure Internet. After evaluating changes of average...
