摘要

Water leakage in water distribution networks (WDNs) can cause serious economic and social impacts.Therefore, it is urgent to discover the efficient sensor deployment methods to monitor the leakage of WDNs.While related research studies mainly consider the single-point leakage, this paper firstly presents a pressure sensor deployment strategy to deal widi the problem of the multi-point leakage occurred in WDNs. The novel proposed label space dimension reduction joint mutual information method (LSDR-JMI) is based on a filter multi-label feature selection algorithm. The label space dimension reduction (LSDR) method is based on the dependence of the label matrix on the leak cases to obtain the optimal label subspace. Then the optimal subset of feature matrix is calculated according to the relevant information between the optimal label subspace and the feature matrix. This method is applied to two hydraulic networks simulated by EPANET to demonstrate its effectiveness and advantage.
