Robot defeats world's top poker players in breakthrough for Artificial Intelligence

Facebook and CMU's poker AI beat five pros at once

Facebook and CMU's poker AI beat five pros at once

Here is how the software succumbed the world's poker elite. In a two-player game, it can be an effective strategy for AI - ideally, the human opponent will slip up or upset the equilibrium resulting in a win for the machine but at worst, the game will result in a tie.

An AI poker gamer created by research scientists from Facebook AI and Carnegie Mellon University has defeated two of the World's best poker players.

Pluribus first took on Chris "Jesus" Ferguson, a player who has won the highest distinction in poker by topping the World Series of Poker six times.

As a reminder, Pluribus' achievement comes after various other experiments on Libratus AI, which was able to defeat players in a two-player Poker setup. There were also games in which one human played against five AIs.

But the tables turned overnight as an algorithm trained by the might of Facebook AI and Carnegie Mellon University beat the poker professionals at the latest showdown in Texas.

This is a milestone for AI, which can now beat more than two human poker professionals simultaneously at their own game. Misleading information is proffered readily and an AI is really no good judge of character.

Sandholm has led a research team studying computer poker for more than 16 years.

After years of research, a predecessor of the AI, Claudico, was fielded at the Brains vs.

Now scientists have created an artificial intelligence (AI) bot that can best even the top human players.

"Whenever playing the bot, I feel like I pick up something new to incorporate into my game", poker pro Jimmy Chou said in a statement released to the press. "There's no going back". Thus, Libratus was born.

A bot playing better than top humans in multi-player Texas Hold 'em is seen as an AI milestone - like when IBM's Deep Blue supercomputer beat chess legend Garry Kasparov. That forced the researchers to build Pluribus a decision-making apparatus more complex than those of the other game-playing bots.

The Brains vs AI tournament held in 2017 at the Rivers Casino in Pittsburgh.

The research is a joint project between Facebook and Carnegie Mellon, and the bot was upgraded for full multiplayer poker.

Sean Ruane, one of the players who took on Pluribus, found the program a tough opponent.

Games with three or more players present AI with significantly more variables, i.e., considerably more to think about, work out, and make predictions.

The objective was clear: devise a way for the AI to follow through with all different moves players do. The last surviving one of us would develop into an instant millionaire. In chess and Go, both players can see everything that goes on on the board. But Pluribus placed donk bets far more often than the professionals it defeated.

Facebook says that it has no plans to make the Pluribus program code public in case it has a negative impact on the poker community, although examples of techniques used will be provided to other AI researchers. It either raised or folded, rather than calling. Strategic Machine applies the technologies to poker, gaming, business and medicine, while Strategy Robot applies them to defense and intelligence.

For that reason, Sandholm calls poker an "imperfect information" game with unknown variables, much like real-world scenarios including business deals predicated on market variability. It didn't follow any patterns and played with bet sizes that varied all the time, introducing additional confusion among the players.

Where does that leave the human player? "And that's what makes it so hard to play against", said one of the humans, Jason Les.

Of course, the true advantage of Pluribus has is consistency.

The success of Pluribus has been welcomed but it has also made people question the future of the game.
