AlphaGo-AlphaGo Game 3: Three 3-3 invasions, a big moyo and a fight that fills the center of the board

Thursday August 3, 2017

This exciting game features an astonishing three invasions at the 3-3 point, prompting Michael Redmond 9p to note that “This version of AlphaGo 2017.08.03_AlphaGo vs. Alphago Game 3will invade here at any time when there is no urgent fighting going on. AlphaGo played an early invasion at the 3-3 in just two of the 60 Master series games, but that was shocking, as it defied the common knowledge of pros that such an early invasion should be bad. In this 50-game series AlphaGo played an early 3-3 invasion about 40 times.”

“Black plays a big moyo game, and then chases an eyeless White group into Black’s moyo, to start a fight that fills the center of the board,” adds Redmond.

The video is produced by Michael Wanek and Andrew Jackson.

AlphaGo-AlphaGo Game 2; Fighting throughout, a surprising sacrifice, a final huge ko

Wednesday August 2, 2017

“In this game AlphaGo shows great flexibility in the early stages, and also its ability to calculate extremely complicated fights later in the game,” 2017.08.02_AlphaGo vs. Alphago2says Michael Redmond 9P in his commentary on Game 2 in the AlphaGo-AlphaGo self-played series. Click here for his video commentary, hosted by the AGA E-Journal’s Chris Garlock, and follow along with the sgf below, which includes the extra variations Redmond refers to in the video. “Against Black’s sanrensei, White plays two unusual moves at 10 and 16 to create a unique opening,” says Redmond. “As the fighting starts, White makes a surprising sacrifice, abandoning a group to take the offensive in the center. Fighting continues throughout the game to climax in a final huge ko.” The video is produced by Michael Wanek and Andrew Jackson.

Redmond’s AlphaGo-AlphaGo commentaries launched

Tuesday August 1, 2017

In the first in a new series of AlphaGo video commentaries, Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews Game 1 of the amazing AlphaGo vs. AlphaGo selfplay games. The 50-game series was published by Deepmind after AlphaGo’s victory over 2017.08.01_AlphaGo vs. Alphago with Michael Redmond 9p Game 1world champion Ke Jie 9p in May 2017. Games 2-4 will be released this week, leading up to this year’s U.S. Go Congress in San Diego, which starts on Saturday.

“In the Master series earlier this year, AlphaGo first showed its big shimaris, and often played to dominate the center of the board in the early opening, using its famous shoulder hits to do so,” says Redmond. The Master version “had an early advantage in almost all of the games,” Redmond says, “and I was impressed with its ability to simplify complicated middle game positions and bring the game to an early outcome. Less convincing was the way Master handled complicated joseki. It also had a disturbing habit of losing several points in the endgame to win by the smallest possible margin.”

“With this new self-played series,” says Redmond, “I wanted to see how these traits had survived AlphaGo’s evolution; five months is a long period of time for a self-teaching AI. The exciting news is that Alphago has changed dramatically.” Click here, to find out how in the video commentary and see below for Redmond’s extensively commented sgf file.

Go Spotting: AlphaGo and Beyond; Robopocalypse Now? Kubo and the Two Strings

Sunday July 23, 2017

AlphaGo and Beyond: The national security blog Lawfare last month posted an article called “AlphaGo and Beyond: The Chinese Military Looks to Future ‘Intelligentized’ Warfare,” reports Kyle Highful. “Among other things, this article discusses alleged Chinese censorship of AlphaGo’s match with Ke Jie, recent advances in American and Chinese artificial intelligence, and possible military implications of AI 2017.07.19_KuboGobreakthroughs like AlphaGo.”

Robopocalypse Now? The 2017 Summer issue of “The Bent” has an article titled “Robopocalypse Now?” that includes several paragraphs on AlphaGo as an example of the recent progress in Artificial Intelligence, reports Jeff Newmiller. The Bent is the official news magazine of the Tau Beta Pi engineering honor society“The title was a bit of fluff… the conclusion of the article is that AI is more likely to yield surprise responses to unexpected input than to purposely mislead us.”

Kubo and the Two Strings: “Last weekend I watched the movie Kubo and the Two Strings (right), released in 2016 by Laika Entertainment and currently available on Netflix,” writes Alicia Seifrid. “It is a stop-motion fantasy film set in feudal Japan.  Early in the film, the main character Kubo goes into the village, and you see the villagers going about their everyday lives, including two men playing go.  Thanks as ever for sharing so much enjoyable and interesting go news!”

Researchers in China use appreciation of go to develop accurate chemical model

Sunday July 2, 2017

Zeolites, porous aluminosilicate minerals, are a key catalyst for industrial use due to their unique structure. As a result of their porous nature,2017.07.01 zeolites these minerals aid chemical reactions involving molecules directly bordering the zeolites, but carbon deposits can have a negative effect on surrounding molecules. As a result, models of Zeolites in 2d space behave similarly to some aspects of go, because the spaces bordering carbon deposits essentially act as liberties do in go. When an area of the model becomes completely surrounded by carbon deposits, those areas are inaccessible, despite not having carbon deposits themselves. Inspired by AlphaGo’s matches with Lee Sedol, Chemical Engineer Fei Wei and a team from Tsinghua University developed a detailed model that not only accurately described experimental results, but also allowed the team to predict the optimal acid density of a particular type of zeolite. A catalysis expert, Bert Weckhuysen, called the model “interesting and elegant” and added that he “directly see[s] a lot of potential applications.”

Lego go set idea seeks support

Saturday July 1, 2017

While several different Lego chess sets have been created and marketed in recent years, David Fazekas thinks the Danish plastic brick company 2017.06.30_lego-go-setis missing a big opportunity. “After Deep Blue defeated Kasparov in 1997 Lego had made several official Lego chess sets,” says Fazekas, promotion executive for the PaGoda Go Association in Hungary. “Now that Deep Mind’s AlphaGo has defeated both Lee Sedol and Ke Jie it’s time for Lego to acknowledge go players with a Lego Go set!” Fazekas has developed a Lego go set prototype and submitted it on the Lego Ideas site, where he needs to gather 10,000 supporters to advance to the next step in the approval process. Thus far he has 754 supporters. “A go Lego set would reach kids in every country,” says Fazekas, “please take a moment to click to show your support for this project.” The word “lego” is derived from the Danish words “leg godt”, meaning “play well”.

In surprise announcement, AlphaGo retires; DeepMind to release 50 self-play games

Saturday May 27, 2017

AlphaGo is retiring. DeepMind’s Demis Hassabis and David Silver made the stunning announcement as the Future of Go Summit wrapped up in Wuzhen, China, saying that the match against world #1 Ke Jie represented “the highest possible pinnacle for AlphaGo as a competitive program” and would be the AI program’s final match.2017.05.27_alphago

“The research team behind AlphaGo will now throw their considerable energy into the next set of grand challenges, developing advanced general algorithms that could one day help scientists as they tackle some of our most complex problems, such as finding new cures for diseases, dramatically reducing energy consumption, or inventing revolutionary new materials,” Hassabis said. “If AI systems prove they are able to unearth significant new knowledge and strategies in these domains too, the breakthroughs could be truly remarkable. We can’t wait to see what comes next.”

DeepMind isn’t leaving the go community empty-handed, however. As a “special gift to fans of Go around the world,” DeepMind is publishing a special set of 50 AlphaGo vs AlphaGo games, which Hassabis and Silver said “we believe contain many new and interesting ideas and strategies for the Go community to explore.”

And while DeepMind doesn’t plan to give AlphaGo itself a wide release, Hassabis says he’s more than happy for others to make use of DeepMind’s research themselves. Programs like Tencent’s Fine Art and Japan’s DeepZenGo have used similar deep-learning techniques to achieve around 9th-dan level, according to Hassabis. DeepMind will soon publish another paper on how it architected the latest version of AlphaGo, AlphaGo Master, and Hassabis expects other companies to learn from the new research.

Also, Hassabis said that “We’re also working on a teaching tool – one of the top requests we’ve received throughout this week. The tool will show AlphaGo’s analysis of Go positions, providing an insight into how the program thinks, and hopefully giving all players and fans the opportunity to see the game through the lens of AlphaGo. We’re particularly honoured that our first collaborator in this effort will be the great Ke Jie, who has agreed to work with us on a study of his match with AlphaGo. We’re excited to hear his insights into these amazing games, and to have the chance to share some of AlphaGo’s own analysis too.”
