Researchers Cesar A. Hidalgo, Elisa Castañer, and Andres Sevtsuk created a computer model to predict the mix of electronics stores, bakeries, and other businesses found in a given neighborhood. How we define a neighborhood and its boundaries is subjective, so the team used a clustering algorithm to locate dense group lines of amenities that represent human-identified neighborhoods like Boston's Central Square. The predictive model, which incorporates this algorithm, is sure to be invaluable in determining the optimal mix of city's amenities.
