The network of Zachary karate Club (Experiment 1). a Q matrix, estimated by ACD, as the expected value of \(Z_{ij}\) over the variational distribution. b The inferred anomalous edges, i.e., the entries of Q with the values above the threshold, here, the threshold = \(0.7\times max(Q)\). Here, \(\mu = 0.1, \pi = 10^{-4}\)
