Artificial intelligence programs have bested humans in checkers, chess, Go and two-player poker, but multi-player poker was always believed to be a bigger ask. Mission: accomplished.
Researchers at Carnegie Mellon University, working with Facebook’s AI initiative, announced Thursday that their program defeated a group of top pros in six-player no-limit Texas hold ’em.
The program, Pluribus, and its big wins were described in the US journal Science.
“Pluribus achieved superhuman performance at multi-player poker, which is a recognized milestone in artificial intelligence and in game theory,” said Tuomas Sandholm, a computer science professor at Carnegie Mellon.
Sandholm worked with Noam Brown, who is working at Facebook AI while completing his doctorate at the Pittsburgh-based university.
“Thus far, superhuman AI milestones in strategic reasoning have been limited to two-party competition,” Sandholm said in a statement released by the school.
According to the creators of Pluribus, the technology could be used to solve a “wide variety of real-world problems” that, like in poker, involve actors who bluff, or hide key information.
The program first defeated two major poker champions, Darren Elias and Chris Ferguson, who each played 5,000 hands against it.
Pluribus then took on 13 pros in a separate experiment, five at a time. In a total of 10,000 hands, the program “emerged victorious,” researchers said.
First, the program practiced against itself, learning little by little how to use poker moves to best advantage. Surprises cropped up.
“Its major strength is its ability to use mixed strategies,” said Elias.
“That’s the same thing that humans try to do. It’s a matter of execution for humans — to do this in a perfectly random way and to do so consistently. Most people just can’t.”
One surprise was that Pluribus used “donk betting” — ending one round with a call and starting the next with a bet — far more than would the pros, who traditionally see the move as a weak one.
Brown even ventured so far as to say that some of the program’s strategies “might even change the way pros play the game.”
‘Why do we need camo in space’: Trump’s Space Force ridiculed for woodland camouflage uniforms
On Friday, the United States Space Force released an image of their new uniforms on Twitter.
The image shows a Battle Dress Uniform (BDU) for a four-star general in a woodland camouflage pattern, with a matching camo nametape.
However, many people were confused as to why the Space Force would use uniforms designed to blend in on earth.
Here's some of what people were saying:
Sorry for the question but why do we need camo in space?
BUSTED: National Archives caught doctoring exhibit to remove criticism of President Trump from women
The National Archives were caught editing an artifact from the Trump administration to remove criticism of the president, according to a bombshell new report in The Washington Post.
The newspaper reported on a "large color photograph" at the National Archives exhibit marking the centennial of women's suffrage.
"The 49-by-69-inch photograph is a powerful display. Viewed from one perspective, it shows the 2017 march. Viewed from another angle, it shifts to show a 1913 black-and-white image of a women’s suffrage march also on Pennsylvania Avenue. The display links momentous demonstrations for women’s rights more than a century apart on the same stretch of pavement. But a closer look reveals a different story," the newspaper noted.
Dershowitz is running a ‘bizarro defense’ of Trump: Harvard Law colleague says ‘Alan is just completely wacko’
Two of the most famous names associated with Harvard Law School had competing appearances on MSNBC on Friday.
It began when Alan Dershowitz, a professor emeritus, was interviewed MSNBC chief legal correspondent Ari Melber about his new role officially representing President Donald Trump during the Senate impeachment trial.
Dershowitz claimed that neither abuse of power nor obstruction of Congress count as "high crimes" under the constitution.
Professor Alan Dershowitz, who has also been associated with Harvard Law for five decades, was asked about Dershowitz's argument during an interview with Chris Hayes.
