1. A method, comprising: receiving, at a computing device, a plurality of geofence-status indications, wherein at least one geofence-status indication of the plurality of geofence-status locations comprises training data associated with a geofence at a first location, and wherein the geofence is associated with a geographical area; training a geofence-status classifier of the computing device to determine a status of the geofence by providing the training data as input to the geofence-status classifier, wherein the training data comprises data for each of a plurality of training features; after the geofence-status classifier is trained, receiving query data associated with a second location at the computing device, wherein the query data comprises data for each of a plurality of query features, and wherein the plurality of query features comprises at least one query feature that corresponds to at least one training feature; providing the query data as input to the trained geofence-status classifier; and after providing the query data as input, indicating the status of the geofence using the trained geofence-status classifier.
