I am the only one who practices magic: I practice magic in the city

Chapter 218: Man vs. Machine (I)

A conference room on the sixth floor of the Four Seasons Hotel in Jongno District was set up as a temporary media reception room. Demis Hassabis and David Silva, representatives of DeepMind, were standing at the tea break area at the door, looking at the cameras of the reporters on the scene, their faces a little stiff.

The reporters on the scene were mainly Korean reporters, but there were also a considerable number of Dazhou media and Youmai media.

Before the press conference officially started, reporters were whispering, discussing in low but intense voices whether this artificial intelligence called AlphaGo could possibly defeat Lee Se-sil.

Soon the staff came to urge them, saying that the time had come and Lee Se-sil had already arrived at the scene and would be present with representatives from DeepMind and the Korean Chess Institute.

The questions from Korean reporters were mostly focused on Lee Se-sil, and the fanatical national sentiment almost scared Hassabis to the ground.

When Hassabis was asked about the chances of AlphaGo defeating the world's number one player Lee Se-ji, he had to keep a low profile for fear of being beaten.

"It's 50-50," Hassabis replied briefly.

Isn't Lee Se-sil ranked fourth in the world now? How did she become first?
Obviously, this answer did not satisfy the reporters at the scene. Whether Lee Se-sil would win or lose was secondary to them. What they wanted to hear more was the flattery of the Koreans by these high-nosed and deep-eyed foreigners.

What about Goryeo being the world's number one in Go, I love Goryeo so much, kimchi is the most delicious food in the world, Goryeo people are very cultured and polite, Goryeo deserves the title in the World Cup semi-finals...

These are what the Koreans are willing to hear.

After the press conference, both parties entered the preparation stage. Fortunately, Google is a Malaysian company, which naturally has a superior position in Korea, thus avoiding a lot of trouble.

Finally, after Lee Se-sil had lunch and smoked half a pack of cigarettes, at one o'clock in the afternoon local time, the two sides finally arrived at the game room on the seventh floor of the Four Seasons Hotel.

Hassabis, David Silva and Huang Shijie have arrived for a long time and are doing the final check on AlphaGo.

"Lee Se-sil has five matches in March, so it's normal to ask for the matches to be put in February, but it just leaves us with much less time to practice."

"If we hadn't adopted the new training structure this time, we might not have been able to complete the last training. In that case, it would still be risky to defeat Lee Se-sil."

Hassabis picked up the bottle of water and took a sip.

"The applicability and efficiency of the youzi0.25b framework are amazing. If I hadn't used youzi0.25b in the last training, I might not have been able to complete the V13 training until now. If I hadn't completed it, this competition would have definitely been postponed."

David Silva nodded in agreement. As the project leader of AlphaGo, no one was more nervous than him about whether this project could be successful.

"It's a pity that their baseline architecture didn't choose a license and is not completely open source." Hassabis shook his head regretfully, "But it's also normal. It seems that this company has just started, and it is reasonable to set up some technical moats. Just like Hinton, he didn't open source AlexNet at the beginning, otherwise he wouldn't have received 40 million dollars from Google."

The Hinton that Hassabis was referring to is Jeffrey Hinton, who is already in his seventies and is a recognized leader in deep learning. He pioneered the concept of deep learning through the back-propagation algorithm thirty years ago.

Four years ago, Hinton released the groundbreaking AlexNet eight-layer neural network model, which used the CNN deep neural network and GPU-accelerated deep learning to greatly improve the computer's visual graphics recognition capabilities.

It was thanks to AlexNet that artificial intelligence first had real commercial value.

Hinton also became famous because of this, and officially stepped out of the circle and was sought after by major companies.

At that time, in order to maximize profits, Hinton did something out of the ordinary. He and two students set up a shell company. This company had nothing but the three of them.

Then Hinton organized an acquisition tender and invited major companies to sign up for auction-style bidding. Whoever bid the highest would be acquired and they would work for that company.

At that time, Qianxun was played a trick. After several rounds of bidding, she always offered the highest bid, but the other party refused to recognize her and still chose Google.

I'm just using you as a proxy, what can you do?

Deepmind also participated in the bidding at that time. Deepmind offered equity instead of cash, so Deepmind was eliminated in the first round of bidding. Therefore, Hassabis has always been dissatisfied with Hinton.

As a result, the two of them now work in the same company. Isn’t that a coincidence?

"I heard that Google is raising the price of EOS Technology. Currently, their EOS framework project has more than 70 branches and more than 300 contributors."

"Their official website updates examples almost every day. The framework has had five major updates and 5 minor updates in three months. The speed is very fast, but they are a big company, so Google has some concerns."

Hassabis chuckled.

"This company is indeed quite mysterious. No one knows who Professor Jorz is, and no one knows whether it is a gimmick inspired by Satoshi Nakamoto. However, if they didn't keep it secret, Jorz might have been poached by a big company long ago." Huang Shijie shook his head.

Hassabis' eyes flashed slightly. He had just sent an email to Professor Jorz a few days ago, promising that if Professor Jorz was willing to join Deepmind, in addition to giving corresponding shares, he would also be willing to let Professor Jorz be the chief technology officer of Deepmind.

Of course, this kind of thing cannot be mentioned in front of David.

At this time, two staff members came forward to remind that the game time was about to end.

Hassabis smiled and put his arms around Huang Shijie and David Silva’s shoulders: “Let’s go, let’s make history!”
-
Although it is a man-machine battle, a chessboard is still placed on the scene, and next to the chessboard is a computer. Huang Shijie will place the chess pieces at the corresponding positions according to the instructions of alphaGo and play against Lee Se-sil on the chessboard!

"It's an honor to play chess with you." Li Shishi politely shook hands with Huang Shijie and sat on one side of the chessboard.

After the referee introduced the rules, Lee Se-sil guessed that black would go first, picked up a black piece and placed it lightly in the upper right corner of the board.

Looks like a very relaxed state.

At the same time, Huang Shijie was also entering Li Shishi's first move into the computer.

AlphaGo's moves were not very fast, and it took about a minute to consider each move, while Lee Se-sil made his moves very quickly without thinking.

"The combination of moves 1, 3, 5, and 7 is not played like this in reality. Lee Se-sil must have wanted to test the AI's judgment logic, but the advantage of being the first mover was basically lost."

Da Zhou was also broadcasting this game live, and the commentator was none other than the real No. 1 player in the world, Gu Jie.

"The AI ​​was not affected and separated the two upper black pieces naturally. The response was standard. Lee Shishi had a bad start. However, for Lee Shishi, it should not be a problem to make up for the loss at the beginning from the AI ​​in the middle game." Gu Jie looked a little gloating and looked very relaxed.

But as the game progressed, both Lee Se-sil on the scene and Gu Jie, who was commentating, were dumbfounded by alphaGo's performance.

"The combination of 24 and 26 punches is very powerful. AlphaGo seems to be much stronger than we thought." Men and women working together make the work more tiring, and the live broadcast platform also assigned Gu Jie a female commentator.

In fact, we were also afraid that Gu Jie would talk nonsense on the spot, so we bought him insurance.

"That's because Li Shishi was too hesitant in his response!" As expected, Gu Jie immediately expressed his dissatisfaction with Li Shishi's play, "If he plays like this, he will definitely lose the game. It's not because AlphaGo is so strong, but because Li Shishi plays so badly!"

The progress of the whole game seemed to be just as Gu Jie said. After being shocked by AlphaGo's chess skills at the beginning, Lee Se-sil did seem a little nervous and frequently fell into long thoughts.

By the 67th move, the player was even holding the chess piece and dangling it on the board.

Even the KBS commentator exclaimed: "Li Jiudan seems to be doubting himself and is a little scared."

"The winning rate has risen to 73%." David Silva was holding a pad and following alphaGo's backstage at all times, quietly reporting the winning rate calculated by alphaGo based on each move.

At this moment, alphaGo seemed to have made a wrong judgment in the lower left corner. In such a good situation, it actually chose 88 tiger!
In this way, the black piece can successfully occupy the lower left corner!
The situation is reversed! ?
The studios of more than a dozen TV stations and five or six live broadcast platforms were all filled with jubilation.

AI made a mistake! Turn defeat into victory!

Is it really?

"The winning rate is still 70%." David Silva remained calm. He knows Go, but he knows alphaGo even better.

Li Shishi was also very excited. In his opinion, White's move 88 was undoubtedly a stupid move. It was obvious that White could have taken advantage of the victory to kill him completely, so why didn't he do that?
Li Shishi snapped twice and took the land in the lower left corner. Then, AI seemed to make a wrong judgment again and gave two pieces of land to Li Shishi.

Are we really going to turn defeat into victory?
After Lee Se-sil confidently cut off the black chess piece in move 101, AlphaGo made a brilliant move almost without any hesitation!
White, play 102.

what! ?

Not only Lee Se-sil, almost all the commentators in the studio exclaimed in amazement.

"Orange!?" Gu Jie also blurted out.

Chen Ying, who was explaining the game nearby, was shocked: "Gu Jie, you said AlphaGo is Orange?"

Gu Jie pondered for a moment and said, "No, I just said that this move reminded me of Orange. AlphaGo is not as good as Orange, and of course, it is not as good as me."

Chen Ying: "..."

"Orange?" Seeing this move, Li Shishi also raised his head and stared at Huang Shijie closely.

Huang Shijie had a question mark on his face: "What orange?"

They have stopped feeding human chess records to AlphaGo since November. Instead, like the Orange model, it has adopted a self-playing method for learning. They have basically not paid attention to news in the Go industry in the past two months. Even if they did, they only paid attention to the world championships. An online chess player who emerged in the Great Zhou Dynasty is not enough to catch the attention of DeepMind.

This is what it means to be a different person.

Although Orange is already well-known in the Go world, the artificial intelligence that specializes in Go is still unknown.

"No, nothing. It's not Orange. AlphaGo's chess skills are not as strong as Orange's." Li Shishi shook his head, but this scene had been faithfully recorded and broadcasted by the cameras on the scene.

As soon as move 102 is made, the outcome of the game is decided.

"Lee Se-sil is going to lose." Gu Jie was the first commentator to confirm this.

"Impossible? Black should have the upper hand now." Chen Ying was a little unsure.

It has just reached the middle of the game. Judging from the situation, Li Shishi does not seem to be at a disadvantage. Moreover, Li Shishi had such a big advantage just now, how could he lose?

"The move just now is the only gap for the black piece on the right." Gu Jie arranged the subsequent chess pieces on the big chessboard, "The black piece can only choose to grow one step, and then..."

After Gu Jie's move, the audience who knew a little about chess understood it.

Black is indeed going to lose.

The black chess piece in the lower corner, which originally seemed impregnable, was easily captured by three pieces by the white chess piece, leaving no room for resistance.

The 88 tiger, which everyone had previously thought was a stupid move, happened to save a small piece of white chess real estate.

But just this little piece is enough!
No matter how you calculate it, by the final stage, Li Shishi will lose at least three points.

Three points may not seem like a lot, but for a game of chess, a difference of half a point means the difference between winning and losing!

"AlphaGo's control over the situation really reminds me of Orange. They both play chess in the same way, which is that the basis for judging where to place a move is not based on how much the situation can be improved, but on how controllable the situation is."

"Of course, I still think that 88 Tiger is not a good move, but it is obvious that AlphaGo thought the situation was under control and that ensuring victory was the most important thing, so it gave up the lower left position. This choice was also made by Orange in the first game against me, but I won at that time."

The comments below the live broadcast room were so loud that I couldn’t even see the screen. They were all telling me, Jiebao, you lost the last two games.

Gu Jie didn't see the comments either, and said to himself: "From this game, AlphaGo's chess skills are probably about the same as when Orange played against me for the first time, but not as good as me. Compared with the last two games between Orange and me, the gap between them and Orange is even greater."

"So I was wondering..." Gu Jie touched his chin, "Is the orange that defeated me in the last two games also an artificial intelligence?"

"Besides, Yicheng is the website of the Great Zhou Dynasty. Juzi appears in Yicheng and is named Zhou Wenming. Maybe it is an artificial intelligence developed by a company in our country?" Gu Jie said excitedly, "In that case, I am still the number one in the human race, hahahaha."

“But, if Orange is an AI, then even you, who is currently ranked number one in the world, lost to him, and you even admitted that you couldn’t beat Orange. Doesn’t that mean that humans have already lost to AI? Doesn’t that mean that Go is dead?” Chen Ying blinked her big eyes.

"Ah!" The smile on Gu Jie's face froze suddenly.

The barrage of comments below became more frequent, and people who knew chess and those who didn’t were all posting barrages and comments.

"It's possible. I looked at Orange's chess records. That chess is simply not something a human can play!"

"Jiebao said it well, our Great Zhou's artificial intelligence is no worse than Mai's!"

"Zhou Wei is awesome! It must be Zhou Wei!"

"The above poster doesn't understand Go or AI. Zhou Wei doesn't work on AI. The only AI in China that can beat him is Qianxun."

"If Orange is AI, it must be from Miami. China doesn't have this technology. Even ballpoint pen refills have to be imported."

"You're all talking nonsense. Ju Zi is a real human being. If Li Shishi loses, it just means that he didn't play well. Do ordinary people understand that masters are more powerful than ordinary people?"
-
"Snap" Huang Shijie placed the 186th move on the chessboard according to the feedback from alphaGo on the screen.

Li Shishi picked up two black pieces from the chess box and tapped the box gently.

"Snapped"

"Snapped"

It's as if time has stood still.

Then, Li Shishi gently placed the two chess pieces on the chessboard.

"I lost."

As the Korean referee announced that AlphaGo had won the first game, Huang Shijie, Hassabis and other members of the DeepMind team cheered together.

AI defeated the top human chess player for the first time!

"I'm very sorry, I would like to ask, have you ever let alphaGo play Go on the Go website?" Li Shishi was not as depressed as imagined. He stood up and shook hands with Huang Shijie and Hassabis.

“?” Hassabis shook his head: “Until now, apart from our team members, AlphaGo has only played against you and Fan Hui.”

"So it's not you." Li Shishi showed a hint of disappointment on his face.

???

What do you mean?
"AlphaGo's thinking in several moves is very similar to that of a chess player I met online. Oh, by the way, his name is Orange. No one knows who he is. Gu Jie and I both lost to him."

Li Shishi said calmly.

"Orange?" Hassabis frowned, but didn't care.

In this world, no matter how strong a human chess player is, he can never be a match for alphaGo!
