WebThe algorithm did detect large blocks of dense subgraph Table 2. The algorithm has low precision (0.03) in detecting injected collusion groups. The algorithm is developed to detect and approximate dense subgraphs that are significantly denser than the rest of the graph behavior, under the assumption that add a large number of edges, inducing a 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. how far is decatur alabama
