Friday July 9, 2021

“Wow, it’s been a while! Welcome back,” Nyarlah commented on the latest Michael Redmond AlphaGo game commentary; Part 1 was published last week. “It’s been too long AGA!” agreed Clay Tin. Some commenters noted the unusually long pre-game chat as Redmond and host Chris Garlock caught up on news from the previous 8 months; note that the game commentary starts at 22:56.

Part 2 of the AlphaGo-AlphaGo Game 50 commentary will be published at 6p ET tonight.  The game series was published by Deepmind after AlphaGo’s victory over world champion Ke Jie 9p in May 2017. The video was produced by Eva-Dee Beech, Chris Garlock and Stephen Hu.

Michael Redmond 9P’s live commentary series resumes this Sunday, August 16 at 8p EDT on Twitch when he and E-Journal Managing Editor Chris Garlock will review Game 45 in the AlphaGo vs. AlphaGo series.

In the latest episode in the Redmond’s Reviews series — which originally aired live on Twitch back in May on Mother’s Day — Redmond takes a look at his game against Yao Zhi Teng 5P. Once again, Michael tries some AlphaGo moves and “things get messy,” he says. Yao Zhi Teng 5p “is one of the younger really strong players,” and this game was played in late 2019 before the competition hiatus due to the COVID pandemic.

Redmond launches new AlphaGo video commentary series

Monday June 8, 2020

In the first days of 2017, rumors started to ricochet around the online go community. A mysterious online player had been making huge waves by defeating dozens of top professionals on go sites in Asia in recent days. “Master” first appeared on December 29, 2016, registering from Korea. Achieving 30 consecutive wins against many former and current world go champions, Master defeated Park Junghwan four times and Ke Jie twice. After that, Master appeared on a different go site and logged another 30 consecutive wins. That made it 60 games in a row with no losses. Was AlphaGo the Master?

Michael Redmond had been on holiday when the games were being played but word had of course spread swiftly through the professional community about the mysterious online player racking up win after win. “That kind of record was simply mindblowing,” he says, “and even before I got the game files off the internet it was clear that something new was happening. Anyone – or anything – that could win 60 straight games could probably give a 2-stone handicap, and these were top professionals who were losing to a player no-one had ever heard of.” The 60 Master games were not only evidence that AlphaGo had attained a whole new level of play, but an incredibly rich “treasure trove for professionals,” says Redmond.

Working again with American Go E-Journal Managing Editor Chris Garlock, Redmond is launching a new series of videos in which he’ll focus on the key points of each of the 60 Master games in brief videos, most of which will be 15 minutes or less. The commentaries will also be the basis for Volume 2 of AlphaGo to Zero: The Complete Games, “as well as a chance to introduce viewers to the professional go players who tackled Master,” notes Garlock.

The first video will be released on Tuesday, June 9 on Redmond’s YouTube channel and the series will be linked on the AGA’s YouTube channel  as well. Stephen Hu is producing the series.

The human player in this first game is 15-year-old Pan Tingyu 1P, who finished #1 in the Chinese professional qualification tournament in 2015. Pan has Black and plays a modern version of the mini-Chinese, and AlphaGo shows a new move in the upper left corner, which has since become the standard move for White in the Chinese opening pattern.

NOTE: The AlphaGo vs AlphaGo series, now up to Game 41, will continue through Game 55.

AlphaGo, KataGo, and the future of AI

Saturday June 6, 2020

Visualization of ownership predictions by KataGo

“There’s something magical about the game of go,” writes Branton DeMoss in a recent blog post. “For thousands of years, it has captured the imagination of those who want to learn what it is to learn, to think about what thinking means. With the recent advent of strong, open source go AI that can beat top professionals, it’s worth tracing the history of the game, why it remained so difficult to beat humans for so long, and what the future of go may hold.”

DeMoss explores the evolution of computer go, and then discusses how AlphaGo differs from the open source Katago. “KataGo attempts to predict a greater number of game outcomes than just value,’ says DeMoss, “in particular, KataGo also predicts final territory control, final score difference, and from each board state the opponent’s next move. As a result of these improvements, KataGo massively outperforms Leela Zero and Facebook’s ELF bot in learning efficiency. KataGo achieves a factor of fifty improvement in training efficiency vs. ELF”.

The creator of KataGo, David J. Wu, answers some of DeMoss’s questions at the end of the article. “I think the AlphaZero-style training loop using MCTS (Monte Carlo Tree Search) is not the last word on [things like] this,” says Wu. “Blind spots are just the most visible of the flaws, but there are some technical and theoretical details you can dig into that start to make it clear that there are some practical problems with how exploration and move discovery work in this loop, some basic theoretical flaws involving mismatches between the neural net’s training distribution and usage, and also some fundamental ‘missing’ capabilities in current bots in terms of using search effectively.” The full blog post can be read here. -Story by Paul Barchilon. image from Accelerating Self-Play Learning in Go, by David J.

Friday May 29, 2020

Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews the 41st game of the amazing AlphaGo vs. AlphaGo selfplay games. The 50-game series was published by Deepmind after AlphaGo’s victory over world champion Ke Jie 9p in May 2017.

In this commentary, originally broadcast live on the AGA’s Twitch channel on April 26, Redmond talks about a special video his mother made about the first time a young Michael met Kaoru Iwamoto, “who did so much to promote go overseas.” Today’s game starts with the Chinese Opening, “which is a little unusual for AI’s, we’ll see a few 3-3 invasions and of course some exciting fighting involving some groups where you’ll be wondering if they’re dead or alive.”

Also, tune in this Sunday on Twitch at 7p EDT for another live commentary, this one on the Ichiriki-Shibano game from Pandanet’s recent “Golden Panda Cup”
