The intention of the researchers was, as you might guess, to accelerate and improve the process of turning satellite imagery into Google’s famously accurate maps.
What tipped the team off was that, when the agent reconstructed aerial photographs from its street maps, there were lots of details that didn’t seem to be on the latter at all.
What the agent was actually being graded on was how close an aerial map was to the original, and the clarity of the street map.
The details of the aerial map are secretly written into the actual visual data of the street map: thousands of tiny changes in color that the human eye wouldn’t notice, but that the computer can easily detect.
The colorful maps in are a visualization of the slight differences the computer systematically introduced.
A computer creating its own steganographic method to evade having to actually learn to perform the task at hand is rather new.
As always, computers do exactly what they are asked, so you have to be very specific in what you ask them.
