And here is what it tells us:
In the most recent paper, and one published earlier in the year by the Association for the Advancement of Artificial Intelligence, these were among the predictive correlations:
■ The system was able to accurately predict income, race, education and voting patterns at the ZIP code and precinct level in cities across the country.
■ Car attributes (including miles-per-gallon ratings) found that the greenest city in America is Burlington, Vt., while Casper, Wyo., has the largest per-capita carbon footprint.
■ Chicago is the city with the highest level of income segregation, with large clusters of expensive and cheap cars in different neighborhoods; Jacksonville, Fla., is the least segregated by income.
■ New York is the city with the most expensive cars. El Paso has the highest percentage of Hummers. San Francisco has the highest percentage of foreign cars.
