Just turned over a new leaf and became a wise and intelligent student

Chapter 444 Zero-Sum Game
In June 2011, Beijing officially entered the noisy summer.

Some cicadas that woke up early have already begun to announce their arrival to the world in a noisy way.

Xu Qingshan gets up earlier than the cicada.

He has been running back and forth between the school and the courtyard recently because summer vacation has arrived and Lin Yuehua and Lin Qingying have also had their summer vacation. He really abandoned the two old men and ran to Beijing to see the children of the two families.

Jiang Huanxi and Tong Tong were preparing for exams, so they went to live in Yandongyuan, leaving Xu Qingshan alone to deal with greetings from their two mothers from time to time.

Fortunately, their grandmother accompanies them to go out for a walk from time to time and take a look at the environment of the capital.

Except for occasionally staying at home when sleeping, Xu Qingshan would like to escape from this home as soon as possible at other times.

It’s not that there are any other emotions, it’s just a simple drama between three women, and they are three older women.

"Qingshan, why are you up so early? There is breakfast prepared for you in the room. Remember to eat before going to work."

Xu Qingshan had just come out of the house, and before he even saw anyone, he heard his mother's voice.

He rubbed his eyes and saw Lin Yuehua and Lin Qingying sitting by the pool in the yard, eating melon seeds and watching TV series together.

"okay."

Xu Qingshan looked at the TV that was pushed out in the yard with a strange expression.

The two mothers didn't ask him how they managed to make such an advanced mobile TV.

It's normal for grandma not to be at home at this time. She likes to stroll around the streets in the morning when the sun just comes out.

According to my grandmother's own words, she had never seen Tiananmen Square in her life before Xu Qingshan came to college. As a result, he has lived next to Tiananmen Square in recent years, so he would take a closer look every day before she goes down.

"We're done eating. I'll be leaving first. I'll pick up Xiaoxi and Tongtong tonight. After they finish their exams today, they won't have another exam until next week."

Xu Qingshan came out of the house and gave instructions to the two mothers who were addicted to TV dramas.

"But I need to work a little overtime in the evening, so I might be back a little late. You don't have to cook dinner for us. I can just take them out to eat in the evening."

"Oh, okay, go ahead, go ahead, don't be late."

Lin Yuehua just waved her hand impatiently and poured some of the melon seeds in her hand into the hands of her good sister next to her.

Xu Qingshan felt helpless. He was too tired to complain. Why would he, a lab boss, be late?
Xu Qingshan packed his things and drove towards the school.

Before the car reached the school, Xu Qingshan's cell phone kept ringing on the road. Since he became the boss of the laboratory, his message alerts have never stopped.

Arriving at the parking lot of Jingcheng University, Xu Qingshan did not rush to get out of the car. Instead, he sat in the car and briefly browsed the messages on his mobile phone.

Why is being a top scientist so tiring?

In addition to his normal academic work and teaching students, he also has to contact Qiu Jing from Qingshan Capital from time to time.

Now there are the processes of the Aoyama Institute for Advanced Studies, which require his attention from time to time. In addition, various technical talents need to be recruited from overseas to fill the positions of Aoyama University in the future. Finally, some talents in the chip industry need to be secretly invited back to China to carry out chip research and development.

Xu Qingshan sometimes felt that he was a bit abnormal.

Although I am busy enough with the things I have at hand, I still find careers from outside from time to time that require a lot of my investment.

To be honest, China is so big, and he is not the only one who is working hard to advance his career.

Even if it did not exist in the past, China's industry and technology would still develop rapidly in the 21st century, and it would grow into one of the world's top powers in a very short period of time.

They even have the confidence to confront the United States. Faced with a 104% threat, they are not afraid at all and can even fight back.

Xu Qingshan is very clear about the current international situation.

Before the last two crazy guys were elected president, even though the Western world's technological blockade of China had always existed, there were relatively more opportunities to act secretly.

This is also why Xu Qingshan is working tirelessly and still devotes a lot of energy during this period to recruit talents from the West in various important fields.

Wait until ten years later, when the world situation changes again.

The Western forces that want to strangle the Chinese will be surprised to find that the Chinese have started a new life at some point and regained absolute voice.

Grothendieck and his team are one example, and Bengio’s team who came all the way from Canada is another.

Xu Qingshan met Joshua Bengio who had returned to the Talent Exchange Center of Beijing University.

"Xu, I'm back. This is my student, Ian Goodfellow. According to the original plan, he was supposed to study for a doctorate at the University of Montreal."

During the time Joshua was away, he seemed to become more cheerful. When he saw Xu Qingshan, he smiled warmly.

This time Joshua brought five or six students, both boys and girls, and a Latino student.

As he said this, he introduced everyone to Xu Jinshan, until he came to the last young man next to him who looked a little shy.

"Hello, Ian, nice to meet you."

Xu Qingshan wasn't quite sure what characteristics this shy young man had. He just maintained his usual personality and extended his hand to him in a friendly manner.

"Xu, I really can't believe that I can meet you. I like you very much."

Xu Qingshan found that he was deceived by the young man at first sight. He originally thought that he should be very shy, but after he greeted him, the young man held his hand tightly and began to talk about his mental journey.

It can be said to be a mental journey, or in fact the other party has some understanding of all the work Xu Qingshan has been doing, especially the digital simulation part of the Riemann hypothesis.

"Maybe, they only saw the world you created mathematically. They didn't see the computer concept you implemented when solving the Riemann hypothesis. Although deep learning artificial intelligence can learn to recognize things, they have no way to create things. The quantum generative simulation you use is essentially creating a new existence, even if it is just a number."

The young man looked like he had been holding it in for the entire journey and had a lot to say to Xu Qingshan.

"Ian, be polite."

Joshua frowned imperceptibly and patted Ian's arm gently.

Ian's excitement came to an abrupt end. He retracted his arms and stood there looking like a cowering quail.

I felt very awkward for a moment and didn't know what to do.

"It's okay. I think he's quite spiritual. Let's go and see the place we've arranged for you."

Xu Qingshan stood up with a smile.

Joshua and the others came to Jingcheng University to see him, and could only be arranged to meet here temporarily, but Xu Qingshan had already arranged an office location for them.

"This area is our Beijing University's science and technology park. Although my school has completed the infrastructure, some hardware and software have not yet been arranged in the school, so I can only ask you to borrow a little space in Beijing University to work."

Xu Qingshan took Joshua and others to the science and technology park left for him by Jinda.

At present, Sun Nan is still setting up a chip research and development team. There are not many teams moving into this area yet, and there are still many vacant offices.

Before the digital core strategy was officially implemented, there was no such thing as a confidentiality-level organization.

When Sun Nan is almost ready, Joshua's team will be arranged by Xu Jinshan to go to Qingshan University in Ludao.

"As for accommodation, I will arrange for you to stay at the nearby Beijing University Boya International Hotel. I will book long-term rooms for you because our subsequent research will probably be transferred to the south."

Xu Qingshan and Joshua spoke frankly.

"So it's not very appropriate to arrange dormitories here now."

"After you have chosen your workstations, you can follow me to my laboratory to get your Peking University campus cards, which will facilitate your life on campus and the borrowing of various books." Xu Qingshan and Joshua said as they walked in front of the team.

The students behind him looked at their surroundings with some surprise.

After all, this building has just been newly renovated, and the overall design should be more modern and technological.

This is quite different from when they were in Montreal.

You should know that the capital of Canada is called Ottawa in China. Xu Qingshan has been to Montreal before. Some of the buildings there can be said to be classical Western style, but they have nothing to do with modernization.

“Oh, even the toilets here are smart.”

There was a chubby girl in the team who had just returned from using the toilet. She spoke in surprise to her classmates around her.

"Really? That's great. I'm tired of the old toilet that didn't work properly."

Looking at the students in the team whispering, Joshua felt a little embarrassed and smiled awkwardly at Xu Qingshan.

"The school has been cleaned up here. You can move in today and start to pack up your work."

Xu Qingshan pulled Joshua down without a care in the world and sat down at the long table in the conference room.

The rooms here are all very well appointed and the meeting rooms are separated by glass walls.

There are also electric blinds that can be used for shielding.

Through the glass wall, Joshua glanced at his students outside who were still selecting public health personnel and looking around, and heaved a sigh of relief.

"Thank you very much, Xu. We are going to bother you a lot in the last few years."

Joshua spoke a little nervously.

"What kind of interruption is this? We are just collaborating on a project together. Look, Jessica and the others have no intention of leaving at all."

Xu Qingshan said with a smile.

He actually knew Joshua's thoughts very well. Joshua's personality was rather indecisive.

If Joshua fails to break through his predicament and find the right path within a few years, he will probably leave China and return to Canada or the United States.

For him, Xu Qingshan was just the most likely stepping stone.

Xu Qingshan was not sad about this. He was also very clear that Joshua's team was a first-class team in deep learning.

It’s just that the direction Joshua chose himself does not quite fit in with the current mainstream of international academia.

In fact, Joshua is still the leader of the Montreal AI school.

Even though he brought his team to China to seek cooperation with himself, people outside still referred to him as a member of the Montreal AI School.

But Xu Qingshan was very confident that he could use his ability to transform Joshua into his own shape, making him want to stay in China and Qingshan University.

"Well, thank you."

Joshua is still the same taciturn old Deng.

After a few words, he let their conversation fall to the ground again.

"Knock knock."

When Xu Qingshan was about to open his mouth to find a new topic with some helplessness, there was a knock on the door of the conference room. Ian was seen standing at the door timidly, looking inside.

"Professors, may I come in?"

I don’t know how a sultry old man like Joshua could bring up a socially gifted student like Ian.

Although he looks shy, he is actually very capable in society.

"Come in and sit down. You've already stuck your head in. What else can I say?"

Xu Qingshan greeted the social worker with a smile, who had left a deep impression on him.

Anyway, he and Joshua are just sitting here staring at each other, so why not have a young person come in to give them more topics to talk about?

Ian slid over to Xu Qingshan's side as quickly as a loach and sat down. He immediately put forward his ideas with excitement on his face.

"Xu! Do you have any ideas about computer vision? I've watched your videos before, and I think your approach is correct."

Ian said excitedly, then scratched his head embarrassedly.

"My classmates and I have recently been using generative models to create data, but the facial images generated by computers are sometimes too blurry, with either no ears or no eyes."

"We also thought about using statistical analysis to help the computer create its own avatar, but the amount of number crunching was too large and it was not suitable, so I rejected this idea."

"I wonder if you could give me some advice?"

Ian looked at Xu Qingshan expectantly, wanting to learn from his idol about the development path of his research topic.

"Ian."

Before Xu Qingshan could speak, Joshua interrupted Ian with dissatisfaction.

In Lao Deng's opinion, it is not very polite to talk about work when others are taking a break or chatting.

"It's okay, Joshua, I just had that idea."

Xu Qingshan smiled and shook his head.

"Ian, do you want to try to let two neural networks compete with each other?"

Xu Qingshan said with a smile.

"You should be familiar with Nash equilibrium and zero-sum game."

"Of course, the three core formulas of game theory, as well as the dominant strategy equilibrium."

"Ok."

Xu Qingshan nodded.

“You can try to have two neural networks play a zero-sum game, one as a generator and one as a discriminator, against each other to generate realistic samples from random noise.”

Xu Qingshan tapped his fingers on the table.

When he said this, Ian froze for a moment, and Joshua next to him suddenly straightened his back and became more alert.

“A receiver receives random noise as input and undergoes a nonlinear transformation to generate samples that are close to the true data distribution.”

“The discriminator is then used to distinguish between real data and fake data generated by the generator, and different subsystems are used to maximize the ability to correctly distinguish between the two.”

“As long as the generator can generate high-quality samples that can fool the discriminator, then the generator has learned the real data distribution.”

As Xu Qingshan spoke, the light in Ian's eyes grew brighter.

"What a genius idea, I want to try it!"
