Abstract

Past studies have shown that dense blocks in real-world tensor have anomalous or fraudulent behavior such as zombie followers' behavior or network attack. Thus, various methods have been used for detecting dense blocks in tensor. How-ever, these methods have low accuracy or low recall rate. To overcome those limitations, this paper proposed DDB-BST, which was a method on dense blocks detection based on binary tree search which finds the block with the highest metric in tensor by local search. By comparing key values between child's and father's nodes, it judged whether the binary tree grows. Finally, when the binary tree stop growing, all the child nodes are dense blocks. It mathematically proves the end condition of binary tree growing. Experiments on both synthesis data and real-world data show efficiency of the method, the F1 value with DDB-BST being 30 percent higher than for M-zoom.
