Abstract: In one embodiment, a computing system may receive a request for a measurement project of a communication network for a geographic region of interest. The computing system may identify network metrics for control regions. The control regions may comprise geographic regions connected by the communication network. The network metrics may comprise features that measure a change in a value of a corresponding network metric during a particular time period.
