Chapter 217 AlphaGo's Bug (First Update)
It was late at night, but the third-floor conference room at the Four Seasons Hotel in Jongno-gu, the capital of Goryeo, was still very busy.

The crooked tables and chairs were filled with all kinds of computers and electronic equipment, and all kinds of wires were tangled together on the ground.

A dozen unkempt young people in T-shirts or plaid shirts were sitting or standing, each with more than one display screen in front of them.

The computers and electronic devices in the room are not AlphaGo itself. This artificial intelligence designed specifically for Go is currently distributed on 48 TPUs in Google data centers around the world.

Everything here is just a terminal for debugging and monitoring.

"Is there any problem?" David Silva, who was tall and thin, had not shaved for two days and had an unpleasant odor.

It has been three days since they arrived in Goryeo, and the entire DeepMind team has been mobilized for this game.

Not only the Chief Technology Officer David Silva, but also the CEO and founder of DeepMind, the peerless genius Demis Hassabis, flew from London to Korea with them.

What most people don’t know is that the two founders of Google, Larry Page and Sergey Brin, also came to Korea at this time.

It is conceivable how much importance Google attaches to the game between AlphaGo and Lee Se-sil!
This is the first appearance of artificial intelligence in the eyes of the world!

This is a day that will surely go down in history!
However, Larry Page and Sergey Brin did not appear on the scene, but were taken away by the tycoons to participate in a mysterious reception.

"I found a small problem in the last two tests." Fan Hui took off his glasses and rubbed his eyes. The marks left by the nose pads of his glasses were visible on his nose bridge, and his eyes were full of red bloodshot.

"I found that when I played with white, the AI ​​always seemed to crash when I played these variations."

Fan Hui leaned back in his chair, his face full of fatigue. He hadn't had a good rest for three days.

It’s not easy to get money from Google.

He has a typical square face and his eyes are always staring straight ahead, which sometimes makes people feel that the expression on his face is a little strange.

Fan Hui was originally from the Great Zhou Dynasty, and was assigned a position in the Great Zhou Dynasty.

When he was 17, he realized that his talent would not allow him to become a top chess player in his lifetime, so he went to Gaul to study abroad alone.

After working for two years, he picked up Go again and became the Go Europ Champion for three consecutive years.

There are many Go enthusiasts in Europ, especially since Deep Blue defeated Kasparov. Go, as the only chess game that has not been conquered by computers, has attracted many smart people who want to prove their intelligence to join.

Last October, Fan Hui received an invitation from Demis Hassabis and flew from Paris to London to participate in the game of AlphaGo.

According to Google's paper, Fan Hui lost to AlphaGo 0:5.

But in fact, the two parties signed a contract for ten games, five official games and five non-public test games.

In the test games, Fan Hui won two games, but these two victories were not recorded in the paper published by Google in Nature.

Because it is not conducive to the promotion of AI.

Of course, at that stage, AlphaGo's chess skills were only equivalent to that of a professional fifth-dan player.

After three months and four rounds of in-depth training, AlphaGo has now completely surpassed the top nine-dan players in terms of chess skills. Unfortunately, in some extreme cases, some bugs will occasionally occur.

As a special tester of AlphaGo, Fan Hui's job is to find more bugs before playing against Lee Se-sil to ensure that the AI ​​will not fail temporarily during the game.

"Huang, can you solve it?" Hearing Fan Hui's words, David Silva unconsciously became a little nervous and turned to ask another middle-aged Chinese man wearing a shirt who was a typical stereotype.

This middle-aged Chinese man is the real driving force behind AlphaGo, the designer who applied MCTS to AlphaGo, and the first author of the groundbreaking article "Mastering the Game of Go through Deep Neural Networks and Tree Search" in Nature, Huang Shijie.

Huang Shijie wore thick glasses and looked like an accountant. He smiled awkwardly at David Silva: "David, we are working on it."

"How long will it take to resolve?" David Silva asked immediately.

Huang Shijie was embarrassed: "We haven't found the problem yet."

"Damn it!" David Silva looked at the time. It was already two o'clock in the morning. There was a press conference at ten o'clock in the morning, and the war would officially start at one o'clock in the afternoon.

There are still bugs that have not been fixed at this time. What if Li Shishi seizes the opportunity?
David Silva, who hadn't showered for two days, broke out in a sweat and the stench on his body became stronger. Huang Shijie was too embarrassed to hide and his breathing became unnatural.

"David, don't be too nervous." Demis Hassabis, who was wearing a black T-shirt and had a slightly Mediterranean look, patted his old partner on the shoulder.

"This is just a small problem, and the probability of it happening is very low. It is unlikely that Lee Se-sil will catch it during the game."

"After calculation, the probability of Lee Se-sil winning is only 0.5%." Demis Hassabis bent down and looked at Fan Hui's chess record.

He actually has half Chinese ancestry and is an absolute child prodigy. After he was admitted to Cambridge University when he was less than 16 years old, Cambridge University asked him to postpone his enrollment for a year because he was too young.

Hassabis used this year to develop the world's first business simulation game, and the first sandbox game - "Theme Park". This game was sold millions of copies by Bullfrog, a famous game development company in the United States, and was rated as one of the top ten best-selling games in 3040.

It is worth noting that Hassabis had already begun applying AI technology to this game 22 years ago.

Before going to college, Hassabis successfully achieved financial freedom with his genius.

After entering Cambridge, for many students, it is not easy to complete their studies in four years.

Hassabis successfully completed all the credits in just two and a half years and graduated early, with a double first-class honors degree that only a very small number of graduates can obtain.

After graduation, Hassabis, who had worked in the gaming industry for several years, felt it was boring, so he went to the University of London to study for a PhD in cognitive neuroscience.

He believes that if we want to create true artificial intelligence, we must first understand what human intelligence mechanisms are like.

Hassabis' first academic paper in neuroscience, "People with hippocampal amnesia are unable to imagine new experiences," was published in the Proceedings of the National Academy of Sciences.

This paper is called a milestone in the field of neuroscience and was named one of the top ten scientific breakthroughs of the year by Science magazine.

Hassabis, who believed he had mastered enough knowledge of neuroscience, founded DeepMind six years ago with two friends who shared the same goal.

Just four years later, two years ago, through the introduction of Peter Thiel, Google acquired DeepMind for 400 million pounds.

At the same time, he was also the youngest chess master in the world.

It can be said that Hassabis’ life is a life of cheating that is comparable to any cool novel. Everyone who has come into contact with him calls him a peerless genius.

And now, this extraordinary genius is just like an ordinary programmer, bending over the computer screen, tapping his fingers non-stop, adjusting the relevant parameters of AlphaGo.

"OK, the problem should be solved." Hassabis stood up. "There are still some problems with the evaluation strategy of the value network. I have marked them. It should be fixed in a few minutes."

Huang Shijie took a look and couldn't help but admire him. Although Hassabis did not fix the algorithm problem himself, he marked the problems and it could indeed be fixed in just a few minutes.

I originally thought it was a training problem, but if that’s the case, it would be troublesome.

After all, there is no time for another round of training now.

"Readjust once more and go back to rest. There will be a good result tomorrow."

Demis Hassabis sniffed and said, "David, you better go take a shower right now. The air in this conference room is almost turning green!"

David Silva smelled his armpit and smiled awkwardly. Hassabis found out where the problem was, and he felt relieved.

"In fact, I really hope that Lee Se-sil can find some bugs and win the game."

David Hassabis picked up the pad and kept swiping. "The topic of artificial intelligence is too sensitive. When artificial intelligence surpasses humans in Go, it will not only attract more attention, but also cause discomfort and panic to some people. If Lee Sedol can win a game, the result may be perfect."

“Should we let AlphaGo give us a game? Or give Lee Se-sil a hint about AlphaGo’s bug?” Huang Shijie turned around and joked with a smile.

"It's not impossible..." Hassabis touched his chin thoughtfully. If it was 5:0, although it would make the world realize the power of AI, the mainstream public opinion would definitely be wailing.

But if Lee Se-sil wins a game, more people will have a favorable impression of AI.

After all, no one likes to exist without flaws.

Moreover, the AI ​​first defeated Lee Se-sil with its overwhelming strength, and then Lee Se-sil used his keen sense of smell to detect the weaknesses of AlphaGo, found the bug and defeated the powerful AI like a Terminator. This script seems to be even more ups and downs and deeply rooted in people's hearts.

"Don't think about these for now. The key point is to defeat Lee Sesil first." Hassabis looked relaxed. He picked up a bag of potato chips next to him and started eating.

"Ugh! What's that smell!?" As soon as the potato chips entered his mouth, Hassabis almost couldn't help vomiting.

He had never tasted anything like this before. It wasn't unpalatable, but disgusting.

"Hahaha, these are Goryeo's kimchi-flavored potato chips. Are you not used to them?" Huang Shijie laughed.

"It tastes like kimchi, so disgusting." Hassabis shuddered and threw the potato chips into the trash can with a look of disgust.

"The smell of kimchi and David's body odor, I really can't stay in this room for even a minute." Hassabis decided to go out and clear his lungs. "Which floor is tomorrow's press conference on?"

"The press conference will be held on the sixth floor, and the game room is on the seventh floor." Huang Shijie responded.

"Okay, the bug has been fixed. Of course, if you need it, we can restore it at any time."

After saying that, Huang Shijie winked at Hassabis.
