From small town scholar to chief scientist

The Chinese Academy of Sciences is located in Shangjing, not far from Shuimu University.

Although the Chinese Academy of Sciences has developed fiercely in recent years, there is one thing to say. Compared with Shangjing University, Shuimu University, and even Shanghai Jiaotong University and Zheda University, etc.,

There are still some gaps.

Maybe they will catch up later, but their mathematics institute still has a lot of talents.

At least in China, Beijing University is hard to match.

It's just a little low-key.

Professor Tian Ye, as well as some senior academicians, can go digging.

Some old academicians dug them up and used them as mascots, and then helped Chongqing Higher Court select academicians, nominate academicians and so on.

As for the masters of mathematics at Beijing University, Zhou Yi will also try to dig out a few.

For example, Academician E Weinan, although he turned to artificial intelligence, but poaching here is tantamount to strengthening the level of the entire artificial intelligence college.

He can also successfully obtain his contacts and influence in various aspects.

In the past two years at Shuimu University, Zhou Yi also traveled frequently and kept in touch.

Even discuss the BSD conjecture with Professor Field.

Not long after, Zhou Yi met Professor Tian Ye.

Professor Tian Ye expressed emotion and said:

"At the beginning when your dean pushed you to come to me to study as a graduate student, I was not even happy. Now it seems that I am not worthy."

Zhou Yi said with an embarrassed smile:

"Academician Yang of Chongqing Normal University also invited me to study in graduate school.
There is a high probability that he went to graduate school there, but I didn't expect that Mr. Qiu and Mr. Mirno invited me later. "

Tian Ye said:

"Professor Zhou, why did you come to see me today? To your Chongqing Higher Court?"

Zhou Yi said:

"Yes, Ding Jian of Shangjing University and Shan Peng of Shuimu University are willing to join us, as well as the golden generation of Shangjing University."

Zhou Yi said the names of a bunch of people.

Professor Tian Ye said:

"With so many people, will it have any impact if I go?"

Zhou Yi said:

"There will be a collision of ideas when there are many people. There are young people there, and the mentality is better when you go there, and the atmosphere is better than in Beijing.

And the funding is no less than yours at the Chinese Academy of Sciences. "

"Let me think about it again, how long have you been away, Professor Zhou?"

Tian Ye asked.

Zhou Yi said:

"At the end of March."

"Well, I'll give you an accurate message before you leave."

Tian Ye said.

Zhou Yi said again:
"Professor Tian, ​​take me to Academician Yang Le, I want to invite him to go too."

Tian Ye looked confused and said:

"Professor Zhou, are you poaching your teacher's wall? It may not be easy to dig. He is very old and it is not suitable for him to leave Shangjing. The medical treatment in Shangjing is the highest in the country."

Zhou Yi said:

"Give it a try. As long as you can join the Yugao Court full-time, it doesn't matter if you don't come. Our Yugao Court needs a lot of foreign aid."

"Row."

Professor Tian Ye has a high attainment in number theory and BSD conjecture,

He was also invited to give a 45-minute report at the International Congress of Mathematicians.

The level is not low.

Not long after, Zhou Yi met Academician Yang Le.

Academician Yang Le said with emotion:

"When I first met you, I was at the IM International Conference of Chinese Mathematicians. I didn't expect you to be a grandmaster by now."

Zhou Yi said very politely:…

"It happened by chance, I'm lucky."

"Want to invite me to Yu Gao Court?"

Academician Yang Le seemed to see through everything and said.

Zhou Yi didn't hide anything, and said directly:
"Yes."

The popularity of Chongqing High Court remains high, everyone is not a fool, there is no need to hide it.

Academician Yang Le looked at his room, exhaled a foul breath, and said:

"Old man, the Institute of Mathematics of the Chinese Academy of Sciences has been my life's painstaking effort. It has been more than 40 years since it was established at that time, and I don't want to leave."

Hearing this, Zhou Yi's heart sank, but Academician Yang Le immediately said:

"But don't worry, I will go on the day you are officially listed. In addition, as long as I am still alive, I will write an academician nomination for you, and vote for your people in the Yugaoyuan."

Zhou Yi said:

"Thank you Mr. Yang, take care of yourself too."

Academician Yang Le said:

"I have been devoting myself to the cultivation of domestic mathematics talents in my later years. There is a high probability that I will not see the rise of mathematics in the Great Xia Kingdom.

I hope you can bring the mathematics circles of Great Xia to rise again. "

Zhou Yi knew that this was the long-cherished wish of the older generation of mathematicians, especially Academician Yang Le, who had been working on these things in his later years.

So he said emphatically:

"Yes, the mathematics and science and technology of the Great Xia Kingdom will reach the peak of the Song and Yuan Dynasties."

The time when the ancient science and technology of the Great Xia Kingdom was at its peak was when it was leading the Song Dynasty.

Although it is very embarrassing, it still cannot obliterate its brilliant achievements in science and technology.

Qin Jiushao's algorithm can still be heard in algebra when Zhou Yi was an undergraduate.

As for the rest, the names of the Great Xia people were hardly heard.

After chatting for a while, Zhou Yi rushed to Shangjing University.

With Academician Yang Le's back, Zhou Yi also breathed a sigh of relief.

In the past, the Great Xia Kingdom had to be divided into several hills, so it could be divided into 6 in total.

Shangjing University was founded by Mr. Chen Shiingshen and Mr. Xiong Qinglai.

Even if Mr. Xiong Qinglai came to Shangjing University from Shuimu University, Shangjing University's mathematics mountain is still the biggest.

However, although Shangjing University has an extraordinary background, it has the most academicians of the Chinese Academy of Sciences, so in some respects, it will have an advantage.

Therefore, it is better for Zhou Yi to recruit people in person, which seems to be sincere enough.

Although Zhouyi has the support from above, some rules still have to go.

In the entire academic world, in addition to hard power, there is still sophistication, not fighting and killing.

The students of the Mathematics Department of Shangjing University saw Zhou Yi coming, as if they saw a plague god.

As for the students in the other departments, they took pictures of Zhou Yi.

Then make crazy fighting sounds and other places.

Zhou Yi came to the Beijing Mathematical Academy, and there was a lot of traffic in it.

Not long after, Zhou Yi met Academician E Weinan,
Zhou Yi wasn't sure if he wanted to poach him, but he wanted to give it a try.

Because academician E Weinan served as the dean of Yuanpei College at Shangjing University, and was also the deputy director of the Shanghai International Mathematics Center;

He is also the first dean of the Beijing Big Data Research Institute, with too many titles.

He also won the Maxwell Award, too many to count.

Zhou Yi's goal is not to dig him out, just don't make trouble for himself in the future. …

Sure enough, there was nothing wrong with the communication with Academician E Weinan.

But still can't dig it out, and the joining of academicians seems to be in vain.

However, it is not certain whether the level of these academicians is as high as the golden generation or Ding Jian.

Then Zhou Yi tried to dig Wang Shicheng and other academicians, but it still didn't work.

But a good relationship will do.

Next, Zhou Yi called Liu Gang of Huadong Normal University and Professor Chen Xiuxiong.

Professor Chen Xiuxiong finally declined Zhou Yi.

Because Academician Tian Zhen's high-achieving student is in Yugaoyuan,
And Chen Xiuxiong and Donaldson, the winner of the Fields Medal, the Craford Medal, and the Shaw Prize in Mathematics, pointed out academic misconduct in 17.
He also founded the Institute of Mathematics at Shanghai University of Science and Technology, and is still a professor at the University of Science and Technology of China.
So it is impossible to come to Chongqing Higher Court.

He felt disgusted when he saw Academician Tian Zhen's outstanding disciple.

In other words, Zhou Yi is generous and kind, and he is willing to dig Xu Chengyang.

As for the academic achievements of the two, let's split it [-]-[-].

After all, Chen Xiuxiong won the Veblen Geometry Prize, which proved Qiu Chengtong's conjecture.

And Xu Chengyang won the Cole Algebra Award.

When Zhou Yi returned to Shuimu University, Chen Danqi and others were waiting for Zhou Yi in Zhou Yi's office.

Zhou Yi sat on his chair and said:

"Is it all done?"

Looking at the expressions of Chen Danqi and Zheng Keyu, it was obvious that this was the result.

"It's done."

Zhou Yi nodded and said:
"Okay, let's talk next door."

After a while, eight people were in the 404 office. After Chen Danqi inserted the USB flash drive,

Said:

"Open the USB flash drive, and click on the only PPT in folder one."

After a while, under voice control, a PPT appeared.

Chen Danqi said:
"Professor Zhou, based on your idea, we will make it soon."

Zhou Yi said:

"Briefly introduce the methods and ideas, and I think I will understand."

"Okay, Professor Zhou."

Chen Danqi said,
"It is well known that a common method of avoiding radar signals from interfering with communications is null space projection,
The principle is to use a zero-forcing precoder at the sending end,

Using the information of the effective interference channel matrix, the radar signal waveform is projected to the null space area of ​​the interference channel through singular value decomposition, so as to eliminate the influence of the radar signal on the communication system.

The NSP method is adopted for the separated antenna deployment scheme, which effectively avoids the mutual interference between the communication system and the radar system.

Another idea to suppress perceived interference is interference neutralization, that is, the radar signal is estimated and reconstructed at the receiving end, and then subtracted from the received signal. "

Zhou Yi nodded and said:
"Yes, this way of thinking and method is correct, it seems that you are indeed ready, and you are no better than the top artificial intelligence masters.

Both the Dean and the Deputy Dean of the School of Artificial Intelligence of our Chongqing Higher Education Institute have staff.

You go on. "

Chen Danqi continued:
"At the beginning, C. Wang et al. proposed a FMCW interference cancellation algorithm based on atomic norm minimization theory and semi-definite programming. The receiving end converts FMCW interference into a single-frequency signal.
The FMCW interference elimination algorithm of the semidefinite programming here is replaced by the optimization method in Zhou's geometry,...

The efficiency has been greatly improved, at least 10 times better than what he proposed. "

Zhou Yi's brain is running fast, consuming a lot of energy to think, while Peony is even simulating,

After a while, Zhou Yi said:
"Your method completes the interference spectrum estimation by AN minimization,

And combine the known radar waveform parameters to reconstruct the interference signal, and then eliminate the radar interference at the receiving end, right? "

Chen Danqi's eyes were full of shock and disbelief. The three of them had been thinking about these methods for more than a month before they came up with them.
I also listened to the suggestions of many of my subordinates before making it.

Unexpectedly, Zhou Yi sat here and listened to her report, and after a few minutes of thinking, he understood the principle.

The feeling for Chen Danqi is that she seems to have returned to the time when she was a graduate student, and she would report her study progress to her boss in a group every week.

But Zhou Yi is not her teacher, and she herself is not a graduate student anymore,
The content they are currently researching is the key to the future intelligent era. I didn't expect Zhou Yi to be so perverted.

Chen Danqi was silent for a long time, and then said more respectfully:

"Professor Zhou, you are right. This algorithm basically improves the transmission performance of OFDM communication receivers in a communication-aware integrated system."

Zhou Yi nodded, praised and said:
"As expected of being from the Shuimu Yao class, Zheng Keyu, it's your turn."

After finishing speaking, Zhou Yi looked at Zheng Keyu and Chu Li.

Don't embarrass Zhou Yi with the apprentice you brought out by yourself, otherwise Zhou Yi will really lose face.

Zheng Keyu said:
"Junior Sister Chu Li, let's talk, hehe."

Zhou Yi nodded and said:
"Chu Li, tell me."

After Chu Li plugged in the USB flash drive and opened her PPT, she began to say:
"Teacher Zhou, we also used the optimization method in Zhou's geometry.

Z. Geng et al. once proposed a beamforming interference suppression method, which uses a coherent phase-coded MIMO radar system for beamforming and interference suppression processing to eliminate interference in the main lobe and side lobe directions of the radar beam.

And B. Li et al. proposed a matrix-based MIMO radar system and a MIMO communication system to negotiate spectrum usage in a cooperative manner to alleviate mutual interference.
We found that the optimization methods they use are not as good as those in Zhou's geometry,
So after we improved, we also made a transformative breakthrough.

After the improvement, we jointly design the communication system and the radar system, and give priority to the radar sampling scheme and the communication system precoding matrix. "

Zhou Yi took the words and said:
"This method can minimize the interference of communication signals to radar under the premise of meeting the communication rate and power constraints,

You have also grown a lot, so you can move on to the next project,

You can post articles in this direction, directly to Chongqing Higher People's Court, and they can be counted as the doctoral dissertations of the four of you. "

There are 4 directions involved in the theory and technology of communication-sensing integration,
Among them, the communication-sensing integrated interference control is divided into three small directions,

It doesn't matter which direction it sends out.

If the three small directions cannot be combined into one, the effect will only be greatly reduced. …

So Zhou Yi is not worried.

Only four people said happily:

"Okay, Mr. Zhou."

Because it means they can graduate with a Ph.D.

Counting the time they came earlier, it took less than a year and a half to graduate with a Ph.D.
It can be regarded as the speed of the gods.

Chen Danqi and the others on the side were very envious, as expected, only masters can cultivate masters.

Zheng Keyu, Chu Li, Bai Yuting, and Wang Guangzhou obviously already have a bit of a big boss' temperament.

Zhou Yi thought for a while and asked:

"Are you going to get a diploma from Chongqing Higher Academy or a diploma from Shuimu University?"

The four of them looked at each other, not knowing how to make a choice.

Chongqing University now belongs to Shuangfei, and Shuimu University is indeed a top domestic school.

This choice seems to be easy to choose.

The four were stunned for a moment, and Qiqi said:

"Ms. Zhou, we want a diploma from Chongqing Higher Education Institute. After this thesis is published, the diploma is basically useless to us, and we have a lot of money, so we don't need the doctorate certificate and graduation certificate from Shuimu University."

Zhou Yi nodded and said:
"In the future, Chongqing University will not have a lower status than Shuimu University, and now we will continue to assign tasks and work on the remaining directions of communication-sensing integration theory and technology.

This time, it is much more difficult than last time. Instead of being responsible for a small direction, each team is responsible for a major direction. "

Chen Danqi said excitedly:

"Good Professor Zhou, we have almost mastered the theory now, and we have done two large-scale systems in practice, so we can completely be responsible for the content of one piece alone."

Zhou Yi said:

"Yes, 6G is basically divided into ten major projects,

The large project we are responsible for is divided into four small projects, and the four small projects are divided into several sub-projects.

From the sub-projects to the top step by step, first complete a small project, then complete multiple small projects, and finally the entire large project will be solved by us,
It has accumulated enough experience and theory to solve all 6G projects. "

Progressively, step by step, Zhou Yi thinks it is the best way to train them.

At that time, all seven of them will be able to stand on their own, not weaker than Academician E Weinan at all.

Then everyone carries out different general directions of artificial intelligence, can't they monopolize multiple artificial intelligence directions?

At that time, the entire field of artificial intelligence will depend on Zhou Yi's face.

The seven also knew that Zhou Yi was cultivating them, and said one after another:
"Thank you Professor Zhou."

Zhou Yi said:

"Well, they are all my own people, so there is no need to say thank you. I will pack up and prepare to go back to Chongqing Higher Court at the end of the month. It is time to leave Shuimu University."

There was a hint of excitement in the eyes of the seven people, which meant that they were the first to create a mountain alone.

It has the same meaning as academicians among the six mountains in the mathematics world going to other universities.

Under the hands of others, there are still too many constraints. Even though Yugaoyuan is remote now, it will become a super sacred place for the entire artificial intelligence and mathematics circles in the future.

If Zhou Yi is the originator, then they are the first generation of direct disciples.
