Back in 2015, Google-owned company DeepMind gave its AI access to a series of Atari 2600 games, 49 of which it learned to play its own. One particular title was a bit too complicated for the technique it used, though: Montezuma's Revenge. Now, the team has figured out how to make it "curious" enough to want to win the game. They programmed artificial curiosity into the AI by giving it rewards for exploring more of the platformer's world. The version of the AI programmed with artificial curiosity managed to explore 15 rooms out of 24 and to beat the first room in only four tries. An older model that didn't have incentive to play the game more only explored two rooms.
