"Not all who wander are lost": Can a UAV learn a city by heart — no GPS, no map on board, just a $4 flight computer?
Yes! We found a special-purpose neural memory architecture that ‘remembers’ an exact geo-location, given an in-flight daytime picture of Berlin. The typical miss is 27 m — no GPS, no internet, no map on board, just a 3.1 MB file of weights. It works on 96.5% of camera frames, and it took 81 experiments and $364 to find.
