Detecting cash-out users via dense subgraphs
WebThe underlying structures are then revealed by detecting the dense subgraphs of the pair-wise graph. Since our method fuses information from all hypotheses, it can robustly detect structures even under a small number of MSSs. The graph framework enables our method to simultaneously discover multiple structures. WebFinally, we give a spectral characterization of the small dense bipartite-like subgraphs by using the kth largest eigenvalue of the Laplacian of the graph. Keywords. Local Algorithm; Spectral Characterization; Dense Subgraph; Sweep Process; Small Subgraph; These keywords were added by machine and not by the authors.

We focus on a special class of temporal networks whose nodes and edges are kept fixed, but edge weights regularly vary with timestamps. However, finding dense subgraphs in temporal networks is non-trivial, and its state of the art solution …
Webdeg S(u) to denote u’s degree in S, i.e., the number of neighbors of uwithin the set of nodes S.We use deg max to denote the maximum degree in G. Finally, the degree density ˆ(S) of a vertex set S V is de ned as e[S] jSj, or w(S) jSj when the graph is weighted. 2 Related Work Dense subgraph discovery.
