Murakawa Daisuke Takes Oza Title in Surprise Victory Over Iyama Yuta

Saturday December 20, 2014

In a surprise victory, Murakawa Daisuke 8P defeated Iyama Yuta 9P on December 16 to win the 62nd Oza. The Oza is Murakawa’s first major 2014.12.20_Murakawa-Daisuketitle. This is the first time a player from the Kansai Kiin has won the Oza since Hashimoto Shoji 9P did so 33 years ago in 1981. The final game was played in Toba, Mie Prefecture, Japan. The upset attracted a lot of attention in Japan, because former Oza Iyama Yuta currently dominates the domestic Japanese go scene.

Your Move/Readers Write: An IBM CTO Responds to Scottish Neural Network

Saturday December 20, 2014

“It’s interesting to read about the work of University of Edinburgh to use machine learning to improve the level of playing in computers, (Scottish Neural Network Takes Computer Go to Next Level 12/16/2014 EJ)” writes Nin Lei, Distinguished Engineer and CTO, Analytics and Big Data, STG IBM Systems and Technology Group. “However, the title in their article creates an impression that their research is creating a program that can beat the best human players. If their probability of guessing their next move is only 44%, then their chance of guessing it wrong is 56%.  In a sequence of 10 moves, the chance of getting the complete sequence correctly is 0.56 ** 10, which is a very small number.” Noting that checkers “has been solved via machine learning,” Lei says that “it appears it is promising for go as well.” But because machine learning predicates that there is a pattern in the underlying data set, Lei warns that “it could be so complex that machine learning can only attain a certain level of accuracy.  It seems to me a program needs to have very high level of accuracy before it can play a good game at strong human level.” Lei also says that “Since machine learning is based on pattern recognition, I wonder if a professional can trick the program by using moves that may not be optimally locally but will create patterns that the program has not seen before. I applaud the work they are doing,” Lei concludes. “It is innovative by using a different approach than the existing strong computer programs.  It will be interesting to find out if someday they can come up with an algorithm that can improve the accuracy significantly.”

 

Baduk TV releases More Classic Go Books

Friday December 19, 2014

Another series of classic go books has just been released by BadukTV, reports Shawn Ray (Clossius). The first set of four books 2014.12.18_art-of-closingwas “The Profound and Mysterious,” a life-and-death exercise book written between 1347 and 1349, during the Yuan dynasty. The second and just-released series is “The Art of Closing,”  a 6-book set filled with ancient problems put together by previous masters and translated by Cho Hye-yeon. “It is a level below that of ‘The Profound and Mysterious’ so players 5-kyu and stronger should be able to benefit greatly from it,” Ray tells the E-Journal. “Though I think anyone can take a lesson or two from it.” Click here to buy both as a bundle of all 10 of the books.

Scottish Neural Network Takes Computer Go to Next Level

Tuesday December 16, 2014

“One of the last bastions of human mastery over computers is about to fall to the relentless onslaught of machine learning algorithms,” according to a December 15 report in the MIT Technology review. Why Neural Networks Look Set to Thrash the Best Human Go Players for the First Time reviews the work of Christopher Clark and Amos Storkey at the University of Edinburgh in Scotland, who “have applied the same machine learning techniques that have transformed face recognition algorithms to the problem of finding the next move in a game of Go.”

“The question that these guys have trained a deep convolutional neural network to answer is: given a snapshot of a game between two Go experts, is it possible to predict the next move in the game?…Clark and Storkey used over 160,000 games between experts to generate a database of 16.5 million positions along with their next move. They used almost 15 million of these position-move pairs to train an eight-layer convolutional neural network to recognize which move these expert players made next…the trained network was able to predict the next move up to 44 percent of the time, ‘surpassing previous state of the art on this task by significant margins.’”

After just a few days training, Clark and Storkey’s neural network beat GNU Go almost 90 percent of the time in a run of 200 games, but against Fuego 1.1, it fared less well, winning only just over 10 percent of its games.

“There is no suggestion from Clark and Storkey that this approach will beat the best Go players in the world,” the report concludes. “But surely, it is only a matter of time before even Go players will have to bow to their computerized overlords.”

Thanks to John Goon for passing this along.

Go Spotting: Netflix’ Borgia

Monday December 15, 2014

Go makes an appearance in the Netflix series “Borgia,” which is not to be confused with the similar series “The Borgias.” In the 29th minute of 2014.12.14_borgia-seriesthe third episode (“1497″) of the third season, Cesare Borgia , the illegitimate son of Pope Alexander VI (r. 1492-1503), uses “the game of strategy from the Orient, go,” to give a plan for his conquest of northern Italian states. He uses a thick go board with legs and colored glass beads to demonstrate his point. “The goal is to add as few men as possible; out-thinking your opponent rather than out-fighting him.” The winner does not eradicate his opponent, but rather entices him to surrender.
