Home location inference

advertising

Inferred 'home' location (typically the most common overnight device location over N days) can be wrong for shared devices, frequent travelers, or short observation windows, misassigning the household cell.

Detection

Overnight location observation count below the minimum threshold for a stable home inference, or two candidate locations with similar visit frequency (ambiguous).

Mitigation

Require a minimum number of overnight observations across a minimum date span before inferring home
Flag and suppress ambiguous dual-candidate inferences rather than pick one arbitrarily
