Does anyone have link to papers about the technology behind Libratus?

Re: AI Beats Four Top Poker Players
#52"Each night after the play ended, the Pittsburgh Supercomputing Centre added computations to sharpen the AI's strategy." This sounds more like an "advanced chess" setup, where a human teams up with an AI to play. The title of the article should really be "amateur poker players + AI defeat professional poker players". The real test would be if the AI self-corrected over the length of the tournament, without human inte…
"He added that the professionals had been sharing notes and tips in an effort to find weaknesses in the AI's game-play."
This doesn't sound like they had the goal of conducting a fully controlled experiment here, but it's still interesting none the less.
Re: AI Beats Four Top Poker Players
#53Unfortunately this fails to impress me, merely because you could theoretically build a terrible AI and still win.
The article mentions a similar tournament that occurred last year where the human players won against the AI. Accomplishing this turn-around in the span of a year seems like quick progress to me, and also impressive. It is certainly a link in the sequence to more autonomously adaptive AI. So, while what you say might be logically true, following the progress of AI would indicate that this specific outcome is, in fact, pretty cool. Whether or not you are impressed by it is up to you, but it is progress.

#54it won't be long before we hearing more headlines like: "AI beats top 10 hedge fund managers" to "AI run hedge fund blows up due to black swan event" regardless it's an incredible feat. It really casts questions into what our edge as humans are which is slowly disappearing and we didn't even need to put a brain in a jar and hook it up to a computer....it's deep learning reinforced algorithms that is appearing to outl…
It's just that AI researchers are exploring and finding every single field where deep learning algorithms perform better than humans. Play poker, run hedge funds... But for instance understanding and specially producing meaningful language, let it be natural language or programming language? I hope not so. Because otherwise, your average joe hacker might as well shut down their IDE and say good bye.
Looking at the recent leap in translation between natural languages, it seems that producing meaningful language about various situations is not far off.

>AI beats top 10 hedge fund managers" Hedge funds are already using A.I. successfully. I talked one manager who's team was trying to layer successful individual neural networks into a "bigger brain".
Been there, done that (well kind, of, via several small specialized nets). Actually a pretty good trading strategy, but works better if you actually have capital to use it....
I was under the impression that you need some capital, but not so much that you move the market with your trades. True?

#56Andrew Ng posted a comment about this on facebook: "I'm thrilled about Libratus' Poker triumph--this is a huge step for AI. Othello/Checkers/Chess/Go were theoretically solvable with minimax tree search and sheer computation; but poker, which requires bluffing, needs sophisticated modeling of your opponents and new algorithmic principles. CMU's Tuomas Sandholm has also (in a private email) promised to publish their a…
I'm surprised that Andrew Ng made this claim. The strategy that was built for Libratus' predecessor did not do sophisticated modeling of the opponents, or use new algorithmic principles.
Poker is solved using a very large game tree, just as with the other games. The structure of the tree is modified to support the notion of hidden state, but beyond that it is essentially the same as the other games. The structure for representing hidden nodes was developed in the 1950s by Von Neumann. Most of the algorithmic innovations related to how to update the game tree.
My guess is that the primary innovation for the Libratus strategy was that of scale.

#57EDIT: Read below, I am wrong. I clearly didn't know what I was talking about. This is a great achievement in AI, don't get me wrong, but the headline should read, "AI beats the best four poker players we could find who were willing to play for a mere $200K". All the actual best players play for millions and have a reputation to uphold. They would never agree to do this. They four guys they got are pretty good, and co…
They are at worst top 15 HUNL players in the world.
How was this determined? Online play?

eh, if you've got the money to be worrying about moving the market, you're using brokers' advanced execution algos and darkpools.

IDK that much about the finer parts of trading, since I just approached it from a ML perspective.
What I do know is that it wasn't worth it for me personally to occupy my GPUs. By contrast, larger trading firms would probably like it.
