US Patent 11109194 Location network analysis tool for predicting contamination change

A computing system receives geolocation information indicating aggregated locations of mobile devices configured to move in a geographic area. The geolocation information comprises measured location(s) for a given mobile device of the mobile devices. The system generates a time series representing mobility network graphs over a first time period. The time series is generated by, for each subperiod in the time series, generating data representing estimated movement of member(s) of a population between locations within the geographic area. The estimated movement is estimated based on the geolocation information and a total population for the geographic area. The system generates metric(s) derived from the time series. The system determines contamination information indicating a respective contamination status for locations for each subperiod of the time series. The system generates a computer model to predict changes in the contamination information in a second time period subsequent to the first time period.
