AI beats poker players once more
Pluribus shows that artificial intelligence dominates over human poker player
The world of artificial intelligence (AI) continues to evolve. As new advances are made, AI systems are continuously put to the test against humans to see how far it has come and nowhere do researchers like to gauge its success than through poker. Repeatedly over the past couple of years, AI such as Libratus and DeepStack has shown that it is superior in card games to humans and new evolution of AI has shown that, once again, the rise of the machines continues.
An AI poker bot called Pluribus, a virtual offspring of Libratus, has taken on several poker players in six-player Texas Hold’em, only to emerge victorious – Libratus would be proud. The AI is a collaborative effort between the AI Lab of Facebook and Carnegie Mellon University, and sat down at the virtual felt to play 10,000 hands in 12 days against 12 players. Without exception, Pluribus ruled the tables.
The players were pitted against the bot in two different scenarios – five players against Pluribus and one player against five versions of the AI. The machine won an average of $5 per hand and took $1,000 per hour, which was ultimately described as a “decisive margin” by the researchers. They added, “It’s safe to say we’re at a superhuman level and that’s not going to change.”
Playing against a single opponent shouldn’t be too difficult – the AI only has to follow one rival. However, Pluribus, in six-player, was able to keep up with all five opponents while, at the same time, developing strategies to counter all of their attempts. This led to a deadly combination of unpredictability, power plays and even bluffs that weren’t matched by the AI’s human counterparts. The next step, if a computer can learn how to bluff, should be even more interesting.
