Forest trails are just a distraction from the real story here:<p>&gt; When tested on a new, previously unseen trail, the deep neural network was able to find the correct direction in 85% of cases; in comparison, humans faced with the same task guessed correctly 82% of the time.<p>They made a computer better at identifying trails than a human. That they can manage that and quickly enough to feed a flight control loop with directions is mighty impressive.
