Google Unveils Neural Network with “Superhuman” Ability to Determine the Location of Almost Any Imagewww.technologyreview.com
This is one of these obvious (and fun) application of deep learning that you kick yourself for not thinking about it. Google's AI PlaNet is able to localize 3.6 percent of the images in the street-view corpus at street-level accuracy and 10.1 percent at city-level accuracy., moreover, it determines the country of origin in 28.4 percent of the photos and the continent in 48.0 percent of them.
While this might not sound super impressive at first blush, PlaNet consistently beat human adversaries and if you're still not convinced try and beat these stats on www.geoguessr.com.
