Lee Sedol Notches Win Against AlphaGo in DeepMind Challenge Game 4

Sunday March 13, 2016

Lee Sedol 9P made a comeback Sunday after three consecutive losses, to beat AlphaGo in the fourth game of the Google 2016.03.13-lee-sedol-round4DeepMind Challenge. Playing as white, Lee won by resignation after 180 moves. AlphaGo held a strong position for the first half of the game, but commentators noted that Lee Sedol played a brilliant move 78, followed by a mistake by AlphaGo at move 79. “Today’s game was another example of AlphaGo playing a very interesting, good game,” said English commentator Michael Redmond 9P. “However, move 78 by Lee Sedol was really brilliant — and enabled him to win.“ Song Taegon 9P, the Korean commentator, said that “It seems Lee Sedol can now read AlphaGo better and has a better understanding of how AlphaGo moves. For the 5th match, it will be a far closer battle than before since we know each better. 2016.03.12_demis-reviewsProfessional go players said that they became more interested in playing go after witnessing AlphaGo’s innovative moves. People started to rethink about moves that were previously regarded as undesirable or bad moves. AlphaGo can help us think outside of the box.“ As in the previous games in this match, Lee used up all of his time and two periods of byō-yomi overtime, playing nearly two hours on his last period. With the match score 3-1, AlphaGo has already secured victory in the Google DeepMind Challenge Match, but Sunday’s loss heightens the drama going into the final game, Game Five, which will be played on Tuesday, March 15 at 1pm KST.

Saturday March 12, 2016

Seventeen people attended a go house-party on Friday evening to watch the third game in the Lee Sedol – AlphaGo match.2016.03.12_San-Diego-party Members of the San Diego Go Club and the UCSD Go club gathered at the SDGC president’s home to try to root the human on to victory. “It was almost like a go sports bar,” reports  San Diego Go Club President Ted Terpstra, “with two big-screen TVs, a couple of Macs, iPads and a bevy of cell phones all tuned to the action. The upstairs’ TV was turned on to the DeepMind YouTube analysis by Chris Garlock and Michael Redmond 9P while downstairs some were watching the AGA YouTube channel featuring Andrew Jackson and Cho Hyeyeon 9P. Gobans were scattered around flat surfaces so that the spectators could look at variations during the match. Pizza and pop supplied by the American Go Association added to the party atmosphere. Play was well past the four-hour mark when Lee Sedol resigned and lost the  game and the match. The last of the disappointed and weary group ambled out at 12:30 a.m. PST.”

AlphaGo Scores Another Win to Go Up 2-0 Against Lee Sedol in DeepMind Challenge Match

Thursday March 10, 2016

AlphaGo posted a second straight win against Lee Sedol 9P on Thursday in Seoul. “Yesterday I was surprised but today it’s 2016.03.10_lee-sedol-game2more than that — I am speechless,” said Lee in the post-game press conference. “I admit that it was a very clear loss on my part. From the very beginning of the game I did not feel like there was a point that I was leading.” DeepMind founder Demis Hassabis was “speechless” too. “I think it’s testament to Lee Sedol’s incredible skills,” he said. “We’re very pleased that AlphaGo played some quite surprising and beautiful moves, according to the commentators, which was amazing to see.”

The complex, tense game ran nearly five hours and appeared to offer validation of AlphaGo’s evaluative ability, the main roadblock to proficiency for previous go programs. Hassabis said that AlphaGo was confident in victory from the midway point of the game, even though the professional commentators couldn’t tell which player was ahead.

Lee, the winner of 18 world championships, must now win all three remaining games to win the million-dollar prize.

AlphaGo Defeats Lee Sedol in First Game of Historic “Man vs Machine” Showdown

Wednesday March 9, 2016

AlphaGo scored a stunning win against Lee Sedol 9P in the first game of the historic match between Google Deep Mind’s 2016.03.09_AlphaGo-Lee-Sedol-Aja-Huang-550x366AI and the world’s top professional go player, forcing Lee to resign in just 186 moves. “#AlphaGo WINS!!!! We landed it on the moon,” tweeted DeepMind CEO Demis Hassabis after the game. “So proud of the team!! Respect to the amazing Lee Sedol too.” At a jam-packed post-game press conference, Lee admitted “I was so surprised. Actually, I never imagined that I would lose. It’s so shocking.” Cho Hanseung 9p said that “AlphaGo is much stronger than before, when it played against Fan Hui 2p!” Click here to see the English game commentary by Michael Redmond 9P with Chris Garlock on the Google Deepmind YouTube Channel.

The match began on Wednesday, March 9, at the Four Seasons Hotel, in Seoul, Korea. Lee is playing for one million dollars and, perhaps more importantly, the pride of countless humans around the world who don’t yet wish to see 2016.03.09_lee-press-crushcomputers triumph in the ancient board game go. DeepMind, on the other hand, seek to test the abilities of their machine and make another step along the road towards a general purpose learning algorithm.

Game two of the match is scheduled to take place Thursday March 10 (local time; see below for US details) and Lee said “I am looking forward to tomorrow.”

Humanity the winner at Deep Mind Challenge Match, Google Chief Says

Monday March 7, 2016

“The winner here, no matter who wins, is humanity,” said Alphabet executive chairman Eric Schmidt at Tuesday’s press conference launching2016.03.08_google-press-conf the Google Deep Mind Challenge Match between Google’s AlphaGo and world champion Lee Sedol 9P. Alphabet is the parent company of Google. Hundreds of journalists crowded into the 6th-floor ballroom at the Four Seasons in downtown Seoul. Camera flashes exploded as Schmidt took the stage to proclaim that “This is a great day for humanity. Humans will be smarter, the world will be a better place.” Deep Mind CEO Demis Hassabis called go “The most elegant game humans have ever invented.” Hassabis, a go player himself, noted that because of go’s complexity, “It’s been a longstanding challenge for the AI community to master this game.” Lee Sedol, who a few weeks ago confidently predicted he would defeat AlphaGo, adopted a more circumspect approach this time. “Playing against a machine is very different from an actual human opponent,” the world’s Number 1 told the BBC. “Normally, you can sense your opponent’s breathing, their energy. And lots of times you make decisions which are dependent on the physical reactions of the person you’re playing against. With a machine, you can’t do that.” Indeed, asked about AlphaGo’s strengths, Hassabis sais that “AlphaGo will never get tired and it won’t be intimidated, unlike a human opponent.” Even so, Hassabis said, “We’re many decades away from a real human AI; we’re still playing games.” And Sedol turned a bit philosophical at the end of the press conference, quietly saying that “If I get defeated it might be negative for go, but it is inevitable in this modern life. But it won’t destroy the value of go itself.”

Ke Jie defeats Lee Sedol to win Nongshim Cup for China

Sunday March 6, 2016

Ke Jie 9p defeated Lee Sedol 9p in the final game of the 17th Nongshim Cup on March 5, enabling Team China to take the Cup back home for 2016.03.06_Ke-Jie-trophy-Nongshim-Cupanother year. While Korea has dominated this event, winning it 11 times, China now has five wins; Japan has won it only once. The Nongshim Cup is a team event between China, Japan and Korea, sponsored by the Korean instant noodles company. Lee Sedol had scored three consecutive wins, beating Gu Li, Lian Xiao and Iyama Yuta. The match against Ke Jie was Lee’s fourth in as many days and though some worried that he’d be tired going into the final round, others said it was a great opportunity for Lee because of his form’s sweeping upturn. Although Ke Jie was the last man standing for China, his head-to-head record against Lee was 7-2 and he demonstrated a superior sense of balance in the Nongshim final, resolving a tense middle game with a trade and employing his excellent endgame technique to close out the win.
