False Positives (FP) and False Negatives (FN) for the 7 strategies presented in the Experiments section on the two cost vectors described in the main text, where (a), (c) correspond to cost vector 1, while (b), (d) correspond to cost vector 2. For each strategy s _j , the associated curve in (a), (b) consists of the points \((t,FP_{s_{j}}(t)+FN_{s_{j}}(t))\), while the associated curve in (c), (d) consists of the points \((FP_{s_{j}}(t),FN_{s_{j}}(t))\), where t is a threshold varying from 0–100 %, and \(FP_{s_{j}}(t)\), \(FN_{s_{j}}(t)\) are respectively the false positives and false negatives of strategy s _j after removing all events having supports smaller than t. Note that in Figure (c), (d), the same number of FP does not correspond to the same threshold
