Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining geographic locations of devices. One of the methods includes obtaining an estimated user location associated with each respective IP address block based on observed events from the IP address block; obtaining an estimate of a probability model p(ev|loc), the probability model p(ev|loc) including a respective probability distribution of interest locations for each of multiple user locations; wherein obtaining the estimate of the probability model p(ev|loc) includes calculating p(ev|loc) from a p(zone|loc) matrix and a p(ev|zone) matrix; and using the estimate for the probability model p(ev|loc) and the observed events to calculate an estimate for multiple probability distributions X(loc) associated with a respective IP address block.
