Abstract

A method of estimating the geographical location of an object from location information reported by one or more mobile devices having location determining means comprises collecting location data from the one or more mobile devices, preparing the data by selecting features of the data, training an estimator by inputting selected features of the data, and applying the estimator to a map grid to estimate the location of the object. During training of the estimator a kernel machine operates on histograms of distances that are computed with respect to a considered location and the user reports nearby. During application of the estimator, if the estimator assigns a score above a certain threshold a location is marked as the true location of the object. In case multiple locations are predicted, a subsequent clustering merges multiple predictions into one by using the weighted mean.
