Google has trained a machine to work out the location of almost any photo, just going by its pixels. It trained its system on 126 million images with EXIF geolocations mined from all over the web. The machine outperforms humans at determining the locations of images even images captured inside, without geolocation giveaways or hints such as palm fronds, street signs, local-language billboards or Niagara Falls misting away in the background. It also learned to recognize locally typical landscapes or objects think red phone booths architectural styles, and even plants and animals.”]
