“…Therefore, a vast amount of data must be collected for each class given the range of possible scenarios, and if the real leakage features and network conditions differ from the simulated ones, then the fault location performance may deteriorate. Moreover, in these works the demand uncertainty is not explicitly considered, and some of them assume that multiple flow sensors are installed on the DMA (Wachla et al, 2015;Moczulski et al, 2016). Ultimately, obtaining a data set of all the possible leak scenarios is not a feasible task even for networks with a model that is available.…”
