Network representation is a convenient and intuitive abstraction for analyzing the massive interacting data. Some topological characteristics of the network have been found in the past decade, and community structure is the typical one of them. Community detection has become a hot topic in complex network analysis. In the paper, a hybrid algorithm is presented for solving such problem. At first, we...
Data stream is a new data model that has recently attracted attentions in numerous applications. Considering the continuity, limitlessness of streaming data, this paper proposes a novel method to build a synopsis data structure, Nord_Histogram, for storing streaming data summary and a one-pass approximate algorithm, NHQC, for quantile computation. The algorithm implements quantile queries over data...
