Machine learning system can ID cities via pics

What makes Paris look like Paris? It is instead the details woven into the urban fabric that form a pattern, according to a machine learning system that's part of a U.S.-French visual data mining project. Yes, computers are learning to ID your city just by looking at random photos. Researchers at Carnegie Mellon University and INRIA/Ecole Normale Superieure in Paris had the system look at 40,000 Google Street View images of Paris, London, New York, and Barcelona, as well as eight other cities to find frequent and unique elements. The machine learning program found features like the street signs, balconies, and lampposts of Paris to be distinct.
