Facebook AI still has a long way to go

07/29/2019

For the first time, an artificial intelligence system has beaten a team of professional poker players in a game of six-player no-limit Texas hold 'em. It's the latest and greatest example yet of AI-powered bots excelling at games that once belonged entirely to humans.To be clear, it didn't just win once: The AI, named Pluribus, played 10,000 hands of the popular poker game across 12 days and 13 different opponents, all professionals. In some scenarios, it played five humans and in others, one human went up against five versions of Pluribus.The AI, which was created by Carnegie Mellon University researchers working with Facebook’s AI initiative, prevailed to win an average of $1,000 an hour, or $5 per hand.

What is less clear is what return the research’s funders—including Facebook and, indirectly, the United States Army—might hope to get on their investments.The gambling machine was built by Carnegie Mellon computer science professor Tuomas Sandholm and his PhD student Noam Brown, who reported their work in a paper in Science today (June 11). Since November, Brown has worked as an AI researcher at Facebook, which bankrolled the $56,000 in prize money divided among the experiment’s 15 poker players. Meanwhile, Sandholm’s game theory research, applied in this poker bot, was in part funded by a grant from the US Army Research Office (ARO). The National Science Foundation and the Pittsburgh Supercomputing Center also contributed to the research.

Not only is the information needed to win hidden from players (making it what’s known as an “imperfect-information game”), it also involves multiple players and complex victory outcomes. The game of Go famously has more possible board combinations than atoms in the observable universe, making it a huge challenge for AI to map out what move to make next. But all the information is available to see, and the game only has two possible outcomes for players: win or lose. This makes it easier, in some senses, to train an AI on.
