One of the more exciting developments in AI has been the development of algorithms that can teach themselves the rules of a system. Early versions of things like game-playing algorithms had to be given the basics of a game. But newer versions don’t need that—they simply need a system that keeps track of some reward like a score, and they can figure out which actions maximize that without needing a formal description of the game’s rules.
A paper released by the journal Neuron takes this a step further by using actual neurons…
