Predicting Your Future Location Years in Advance
University of Rochester computer scientist Adam Sadilek has developed a system that can, under certain conditions, predict the location of an individual years in advance. The breakthrough is possible, in part, because of the wide and growing adoption of GPS-enabled smartphones. Almost 50% of the U.S. population now carries a GPS device of some sort, according to the Pew Internet and American Life Project.
Sadilek evaluated a large dataset consisting of 703 subjects (carrying GPS devices) over a variety of different time periods and collected more than 30,000 daily samples.
\"While your location in the distant future is in general highly independent of your recent location, as we will see, it is likely to be a good predictor of your location exactly one week from now. Therefore, we view long-term prediction as a process that identifies strong motifs and regularities in subjects’ historical data, models their evolution over time, and estimates future locations by projecting the patterns into the future,\" Sadilek writes.
The system, called Far Out, could be used to map future traffic congestion, disease spread, and electricity demand. Sadilek will present his paper at the Association for the Advancement of Artificial Intelligence 2012 conference in July.
