AI Program Beats Top Poker Pros in Ground-Breaking Research

"Artificial intelligence has been a scientific area broadly explored over the past decades. And its application in the game of poker has become the focus of research of two scholars from Carnegie Mellon University. Computer science professor Tuomas Sandholdm and PhD student Noam Brown may have developed an AI program that is able to beat some of poker’s brightest minds in No-Limit Hold’em heads-up matches.

Libratus, the name the program is known by, triumphed over four seasoned poker professionals – Jimmy Chou, Dong Kim, Jason Les, and Daniel McAulay – in a 20-day No-Limit Hold’em heads-up playing session. It had accumulated $1.7 million worth of chips by the end of the tournament.

The program had the difficult task to sort through imperfect information, while trying to detect when and whether its opponent was bluffing. Libratus was designed to deploy a rather different approach from the ones applied by other AI products in the past when learning poker.

Each night, the program analyzed its own strategy from throughout the day. Using a complex meta-algorithm, it explored the holes its opponents had spotted in its behavior at the poker table, prioritized them, and patched the three most obvious ones.

Libratus was thus able to self-improve with each day passing. Its creators explained that previous algorithms had been developed to detect holes in opponents’ playing style. In other words, Libratus’ ability to identify the presence and essence of holes in its own strategy is what makes it a ground-breaking project.

The program’s self-learning has also allowed it to build and beat skills that are mainly based on intuition and psychology in people’s case. Bluffing is one such skill. It is essential for the game of poker and it really takes time and persistence to master. However, through trial and error, an old-time yet perfectly effective approach, Libratus has trained itself to mimic decisions based on intuition and the psychology of its opponent.

The program’s creators explained that now and for now it is most proficient in heads-up No-Limit Hold’em games as more players at the table mean more possible outcomes and this makes it more difficult for the computer to go for the best possible moves.

Although trained to play Texas Hold’em, Libratus can be applied in other areas as well, including business negotiations, medical research, cybersecurity, military strategy, and many more that involve incomplete information."

One of the engineers at the last place I worked built a crazy mineral oil cooled computer. Always thought it was freaking cool, this isn't it.
I knew a guy who worked at one of the big Silicon Valley firms. He and some of his friends liked to play with the tech. They built a desktop machine with the processor mounted on a four-pound cube of pure copper machined for coolant flow. I believe the ultimate plan was to fire a jet of un-liquefying nitrogen through it. But I might be exaggerating in memory. He did show me the copper block though ... coolness. I brought a neo magnet (neodymium, not @neosapien) and we had endless fun with diamagnetic and inductive effects. A magnetic pendulum slows RIGHT down when it swings over block of copper ... ideal viscous damping

I have, idk 4+ dozen, 1"×2" neo magnets. My last job built their own linear mag rails, I'd get the rejects. They are great for welding/ fabrication set up... also funny watching people that don't know what they are play with them, SNAP.. MY FINGER!

I have a coupla 2x2s ... and a 4x6 I very carefully made out of two NdFeB magnets 6 inches across and 2 thick. (About a pound of paraffin wax was used as a shock absorber.) Those things are wicked.

I'm bad about not backing up stuff and in fact did have a BSOD with my Win10 sys a while back. This was not a clean install but an update to 10 from 8. Luckily I was able to fix it but the article below reminded me i should have a alternate repair method available. Uses a USB drive.

Yeah I was scrupulous about back ups and testing at work but sort of meh about it at home LOL. Finally bought a couple external drives and back up seamlessly just like I used to at work! Problem solved LOL.

Personally I want a black box that you never even notice, I like looking at the screen. I can't stand all of the lights and clear cases and bs they sell for a tower, I would rather power more fans than led lights so you can see the insides. The op has a good case there, lots of airflow and no blinking lights! My computer is in the living room so I don't want it to draw any attention.

Hey maybe one of you uber geeks can help me with a keyboard problem. I keep pressing the escape key but:

I AM STILL HERE!
