AlphaGo Zero whips AlphaGo, 100-0

NPR reports that a new version of Google’s AlphaGo Zero software became a Go master by learning to play the game only by playing itself, i.e., only by using reinforcement learning (as opposed to supervised learning). Per the report in Nature.com, “AlphaGo Zero achieved superhuman performance, winning 100–0 against the previously published, champion-defeating AlphaGo.”
