The network of POLBOOKS with injected edges (Experiment 1). We compare the performance of ACD in detecting the anomalous injected edges by estimating the confusion matrix for tow different values to initialize \(\mu\). By adjusting the value of \(\mu\), we can tune the recall and precision. a \(\mu =0.5, \pi =0.25\), b \(\mu =0.75, \pi =0.25\)
