AlphaGo doc now available to rent or buy

Wednesday December 6, 2017

“AlphaGo,” the 2016 documentary about the historic AlphaGo-Lee Sedol match, is now available on the Google “Play” store for2017.12.06_alphaGo-movie rental and purchase.
“AlphaGo” chronicles a journey from the backstreets of Bordeaux, past the coding terminals of Google DeepMind, to Seoul, where a legendary go master faces an unproven AI challenger. As the drama unfolds, questions emerge: What can artificial intelligence reveal about a 3000-year-old game? What will it teach us about humanity?

“This is such a beautiful telling of this historic moment,” comments Ben Murdoch on the site. “An intimate and at times tense portrayal of a milestone moment in AI history. Captivating!” says Marek Barwiński.

AlphaGo Zero-AlphaGo Master: A Master misread?

Sunday December 3, 2017

“Although the openings in this series are pretty repetitive, the games themselves vary,” says Michael Redmond 9p in his2017.12.01_ag-ag-zero-master-2 second commentary on the AG Zero games. “So in some, you’ll see a half-point game, and in others we’ll see Master crash. This game is interesting because it’s the first time that Zero has black. Also, later in the game, I get the feeling that Master is acting like it did in the 60-game series earlier this year against top human players, where it thinks its winning and is sort of closing up shop and wrapping up the game. So I wonder whether it mis-read a tsume-go — actually a 60-move sequence — in this game.”

Click here for the first Zero-Master commentary.

“Zero shows a strong2017.11.23_AlphaGo Zero vs. Master with Michael Redmond 9p Game 1 bias for territory, and this makes it’s overall game plan relatively easy to understand,” says Redmond. “Quite often we will see Zero diving into Master’s moyo, with some exciting fighting.”

DeepMind has yet to find out how smart its AlphaGo Zero AI could be

Monday November 13, 2017

“Perhaps the most interesting thing about AlphaGo Zero, though, isn’t how fast it was able to do what it did, or with such efficacy, but also that2017.11.12_hassabis-techcrunch it ultimately didn’t even achieve its full potential,” reports TechCrunch. “DeepMind CEO and co-founder Demis Hassabis explained on stage at Google’s Go North conference in Toronto that the company actually shut down the experiment before it could determine the upper limits of AlphaGo Zero’s maximum intelligence.”

“We never actually found the limit of how good this version of AlphaGo could get,” he said. “We needed the computers for something else.”

Hassabis said that DeepMind may spin up AlphaGo Zero again in future to find out how much further it can go, though the main benefit of that exercise might be to help teach human AlphaGo players about additional, “alien” moves and stratagems that they can study to improve their own play.

AlphaGo Zero-AlphaGo Master: Two openings, less variety

Saturday November 11, 2017

“In the set of 20 games between AG Zero and AG Master, there are pretty much just two openings — i.e. identical moves for about the first 202017.11.11_ag-ag-zero-opening moves — one with Zero as Black and one with Master as Black,” says Michael Redmond 9p in this first commentary on the recently released AG Zero games. “This provides an opportunity to examine how Zero differs from Master, as well as how Master differs from earlier versions. ”

“When AGMaster plays against AGZero, it does not show the variety that it had before,” says Redmond. “As AG does not change within a version, I find it hard to accept that it apparently does not have the option to play moves that it played before in identical board positions. In the ‘Master series’, 60 games played against top pros in Dec 2016 to Jan 2017, Master could play the 3-4 point as it’s first move in about 1/4 of the games when it had Black. Incidentally, AGKeJie also could play the 3-4 point in some of it’s games. The fact that Master repeats the same opening every time in these games against AGZero bothers me and makes me question, is this truly the same version of AGMaster that played the Master series, and if so, what caused it to play the same opening every time in this series, when it was allowed to have variety in previous games with identical board positions? The difference in calculated winning percentage between A and B should be extremely small and I would expect it to have little or no effect on the ultimate win-loss record. This set of games would be much more valuable if Master had been allowed to vary in it’s choices for moves.”

Note that these commentaries focus only on the two openings; watch for a full-game Zero-Master commentary next week. Click here for a playlist of all the Redmond AG commentaries.

AlphaGo-AlphaGo Game 15: New, different and possibly bad

Friday November 10, 2017

“I don’t like to call it weird, but in this game we’re going to see some new and different stuff that AlphaGo is doing with the joseki that I don’t 2017.11.10_ag-ag-thumb-15really understand and I don’t like it,” says Michael Redmond 9p in his commentary on Game 15. “It’ll be interesting to see if eventually I change my mind, but for now I’m going to say it’s a bad move.” Redmond adds that “We’ll also see another typical AlphaGo move later in the game that’s pretty exciting too.”

Redmond announces new series on AlphaGo Master vs AG Zero

Saturday November 4, 2017

“We were expecting DeepMind to make some sort of an announcement (about a new version of AlphaGo),” says Michael Redmond 9p, “But 802017.11.04_agzupdatethumb games was a big present.” (Self-taught AlphaGo Zero bests all previous versions in record time Redmond discusses AlphaGo Zero with the E-Journal’s Chris Garlock in a brief video announcing the launch of a new series of game commentaries. DeepMind released four sets of games for the self-taught AI, including training games, games against the Fan Hui version, the Lee Sedol version and the Master version, which defeated 60 top human opponents earlier this year. “I’m going to be looking at the games where Master plays Zero, mainly because Master is such a popular version of AlphaGo,” Redmond says. Master’s tactics, including big shimaris and emphasizing the center “people wanted to play, but were afraid because that way of playing is weak in territory. Master showed us some successful ways…and is still having an effect on how professionals play. So it’s going to be really interesting to see Master playing against a stronger version of AlphaGo.”

AlphaGo-AlphaGo Game 14: A double kakari and a new joseki

Saturday November 4, 2017

“In this game we’re going to see a double kakari against a star point, a first for this series of games,” says Michael Redmond 9p in his game 2017.11.03_AG-14commentary on Game 14. “In the Master vs. human series back in January, Master would play away when the opponent played a kakari against a star point, sometimes. Now we’ll get to see how Master plays this with White, and it has a special move. Its a new joseki that actually make s some sense, so it’s going to be interesting.”

AlphaGo-AlphaGo Game 13: The large knight’s move enclosure workout

Sunday October 29, 2017

“This is a very different game, in that there are three corner enclosures,” says Michael Redmond 9p in his game commentary on AlphaGo-2017.10.27_AG-13AlphaGo Game 13. “Black isn’t playing a kakari, which is different from what human players do now. So we’re going to have kind of a workout in how to deal with the large knight’s move enclosure.”

Saturday October 21, 2017

“In this game we start with a variation of the mini Chinese opening, so we’re going to have another of these 3-3 invasions,” says Michael 2017.10.20_ag-12Redmond 9p in his game commentary on AlphaGo-AlphaGo Game 12. “It’s a really interesting opening, and it’s one of the games that ends in a collapse, so it’s an unusual game in that way.”
