I have never seen such an important and so strange game of Go. When Li Shishi lost three sets in a row, almost everyone lost confidence in mankind. Who wants the fourth round of the contest on the 13th, "Alpha Dog" in the middle of the game. In the end what happened?
"Li Shishi played well, 'Alpha Dog' also showed defects." Liu Zhiqing, a professor at Beijing University of Posts and Telecommunications and an expert in Go artificial intelligence. He and Gu Li Jiu Duan witnessed the miracle as a TV broadcaster.
In this counterattack against the chess game, Li Shishi made a “dig†in 78 hands. After the game, he was called “stunning hand†by the professional masters of Go. After that, the "Alpha Dog" sneaked into a thousand miles, and eventually it was hard to support.
"Our research on Go artificial intelligence, through the performance of 'Alpha Dog', can be inferred that it has various defects, not invulnerable." Liu Zhiqing said, "I don't know if Li Shishi consulted artificial intelligence experts before preparing for the war. Some experts may be able to inspire him. It is also possible that Li Shishi has some feelings through hundreds of steps.
Liu Zhiqing said that the principle of "Alpha Dog" determines that it has some weaknesses that cannot be avoided. It is too complicated to describe this weakness in professional language. “In simple terms, people use logical reasoning to some extent, and 'Alpha Dog' is weaker in logical reasoning.â€
"Li Shishi's layout is more stable today, and he has been waiting for the opportunity. The situation in the first half seems to be unfavorable to Li Shishi. The complicated attack and killing also makes Li Shishi almost run out of time." Liu Zhiqing said.
Looking back, before the 78 hands, the "Alpha Dog" chess shape seems to be stable, but in reality it hides the structural crisis, which was captured by Li Shishi.
"Not every professional expert can see this opportunity. But Li Shishi is coming out." Liu Zhiqing said that this move is beyond the expectation of "Alpha Dog", and then the game is on the control of "Alpha Dog". Another way.
There is a concept in Go that is called "One Road" - "That is, I have a good move, and the other side has only one road in Huashan. The computer using Monte Carlo algorithm does not seem to count this move, and then it is a mess." "Liu Zhiqing said.
Liu Zhiqing said that another weakness of the "Alpha Dog" is that it uses a neural network to simulate the sense of chess, but the sense of chess will also be biased. Today, the "Alpha Dog" did not expect Li Shishi to go out of "God to the hand", and then some of its "unconventional tricks" let the onlookers shake their heads.
"These weaknesses are common to the algorithm-based Go software, which is a traditional problem in this field. But Google has solved it so well that everyone thinks that these problems do not exist. It seems that it is still not completely solved." Liu Zhiqing said.
At the press conference after the game, the Google team's Hasabis said: "We are here to test the weakness of the 'Alpha Dog'. Li Shishi is a genius who can help us. We are very happy to discover the weakness of the Alpha dog before we can Enhance it."
"This time I lost the game and proved that the 'Alpha Dog' choice and judgment had a problem." Hasabis said: "We are not sure what happened, we will return to the UK to analyze the data."
After the victory of the first round of the "Alpha Dog" on the 9th, Lin Huimin, member of the National Committee of the Chinese People's Political Consultative Conference and director of the State Key Laboratory of Computers, told the Science and Technology Daily reporter not to exaggerate the significance of this artificial intelligence victory.
"Some artificial intelligence deals with the problem of 'measurability'. In various board games, if computing resources and algorithms are strong enough, computers will always outperform humans. But many fields are unmeasurable, including human creation. The artificial intelligence wins, but the design process is still human. The media wins or loses from a game of chess, saying that 'computer defeats humanity' is not appropriate."
