From small town academic to chief scientist

At six o'clock the next day, Zhou Yi got up early as a habit, washed his face briefly and went out for a morning run.

At about seven o'clock, Zhou Yi finished his morning run, returned to his room, made a simple meal and went directly to the office with the materials.

Zhou Yi was already very familiar with the round trip route, and it was impossible not to know the road.

Along the way, there were quite a lot of pedestrians, mostly students from Dongda University. Passing by the library, Zhou Yi could still see people endorsing books at this time.

It stands to reason that the postgraduate entrance examinations are over, and the final exams are also over. There should not be so many talents in this kind of time period.

But Zhou Yi still underestimated the extent of Dongda University students' efforts.

If you have a clear goal in life and work hard for it, you will become a great talent sooner or later.

For example, Mr. Zhang Yitang, after years of hard work, announced the solution to the Landau-Siege conjecture at a ZOOM meeting on October 15 last year, witnessed by more than 300 people.

Once the review is passed, the effect will be no less than when Zhou Yi announced the proof of the 3n+1 conjecture in Lecture Hall 1 of the Institute for Advanced Study in Princeton.

Its importance is countless times greater than the 3n+1 conjecture.

He is really getting stronger with age and is extremely brave.

Mathematics is too age-dependent. The older you get, the worse your mathematical imagination will be. Unless there are enough skills to make up for it, it is hard to imagine that there will be such great results.

Only a few people in this world can achieve the same level of concentration for many years.

Not long after, Zhou Yi came to the office. As expected, the seats were packed, with only Zhou Yi arriving the latest.

Zhou Yi said awkwardly:

"I did some exercise in the morning, so I came late."

"It's not too late, we just arrived."

Academician Cao said very politely.

Lu Zhonghua asked:

"Have Professor Zhou had breakfast? He didn't ask Yuan Zhen to buy you one."

Yuan Zhen on the side looked numb, running errands was a common thing for him.

"Eat, thank you. Let's allocate tasks. I thought it was a bit simple before. The things involved are more complicated than the power grid."

Zhou Yi said straight to the point.

Academician Cao smiled and said:

"There's no rush, don't rush. Let's get familiar with Zhou Shen in the past few days. The information on physics and chemistry you requested before will be sent to you in the afternoon."

Zhouyi said:

"Okay, anyway, I didn't finish reading the information last night. I will read it again this morning. I will divide the tasks in the afternoon and try to solve them as soon as possible."

Zhou Yi is still waiting to do the task.

Three large-scale projects are required to complete task three, and the mathematical knowledge in Hilbert's eighteenth question must be used to complete it.

So far, Zhou Yi has not found any application in which Hilbert's eighteenth question can be applied.

We can only look at their information and data more.

With so many directions, Zhou Yi felt that he could always find a few tasks of his own.

Not only Zhou Yi is reading, but also Peony on the phone. All the information last night has been entered by Zhou Yi.

The documents and information in the USB flash drive were also transferred.

Zhou Yi browsed all morning and read a lot before finally choosing two directions.

At this time Yuan Zhen asked:

"Shen Zhou, our lunch is takeaway. Do you want to eat here or go to the cafeteria?"

Zhouyi said:

"I'm going to eat here. I'm going to choose two problems for analysis: detection of water distribution on asphalt pavement and analysis of drainage intensity of drainage asphalt pavement using regression model. These two problems seem to overlap a bit. There are some problems with the model. I'm going to start from this direction first. Get it."

Zhou Yi said to Academician Cao while reading the information.

Academician Cao said:

"Okay, we'll be responsible for the rest. The tasks in this direction are quite interesting and will promote the application of autonomous vehicles to a certain extent."

Zhouyi said:

"Yes, that's right. I'm going to study this in detail just because I'm interested in it. And if this part is solved, the progress of the project will be greatly improved."

After lunch, it was not until about four o'clock in the afternoon that Zhou Yi sent over the information he needed on physics and chemistry.

At this time Zhou Yi stood up and said:

"Then I will go back to my room to retreat. Regarding the mathematical results, I will provide a more reliable model as soon as possible."

Everyone has already become accustomed to it.

Academician Cao said:

"good."

Not long after, Zhou Yi returned to the dormitory with the things he needed.

Then I turned on the computer and entered it.

In just ten days, we will definitely not be able to thoroughly study the problems involved.

Being able to barely combine the models of the two problems clearly is no small success.

For several days, Zhou Yi discovered that the regression model for analyzing the drainage strength of asphalt pavement was indeed not very accurate.

The result of his paper was to use a regression model to express the influencing factors of drainage intensity, and concluded that the thickness of the drainage layer structure and the slope of the road crown cross slope showed a linear relationship.

However, Zhou Yi's intuition may not be that simple.

At least one variable must be considered before it may have practical application significance.

Zhou Yi thought for a while, then kept checking various information.

Finally, I felt that there is a causal relationship with drainage intensity.

The regression model is established as:

Q=αd+βi+γV+δ;

Q=αd+βi+γVη+δ;

Q=αd+βi+γeV/ξ+δ,

Zhou Yi finally wrote down these three regression models, and then said to Peony in the room:

"Peony, comprehensively collected 40 pieces of data, divided the training set and test set according to 8:2, and conducted 500 iterations. It gave me a reliable result, but I feel that the data and model are still unreliable."

Not long after, on the white wall, Peony projected three mathematical formulas

Q=17.5d+52.3i+91.5V-2370.8;

Q=17.5d+52.3i+2.18V2-1409.5;

Q=17.5d+52.3i+5.6eV/5-885.0,

In addition to these three formulas, there is also a relationship diagram, which is a comparison diagram between the drainage intensity effect of the three models and the actual drainage intensity.

Zhou Yi looked at it, shook his head, and said:

"This relationship is so wonderful. It gives people a very delicate feeling. I always feel like something is wrong."

Peony said at this time:

"Mathematics is a tricky thing, but the master is too suspicious."

Zhou Yi murmured:

"Yeah."

"What does the relationship between void content and drainage strength of asphalt mixtures look like."

At this time, Mudan made a voice call from her laptop and said:

"It's an exponential relationship."

After a while, Peony projected the generated picture on the wall.

Zhouyi said:

"This is a bit scientific, but if there are no errors in the mathematics, then there will be no problem."

After solving the simplest problem, Zhou Yi took a breath and said:

"It will be compiled into a new paper in the evening and can be sent to Academician Cao. The next step is the highlight. I don't know which step they have achieved."

Zhou Yi simply finished his meal and went directly to the office.

"Hello, Professor Zhou."

Many people in the office greeted Zhou Yi one after another.

Zhouyi said:

"I have solved one of the problems. Please see if you need to add anything. I feel that this model is too idealistic and always misses something."

Not long after, Zhou Yi directly copied the data in the USB flash drive.

The paper is not long, about ten pages. Academician Cao said:

"We will give you a message the day after tomorrow at the latest. We are almost done here, but we feel there is something missing. You can also take a look at the various models we have made, and everyone can look at each other."

Zhouyi said:

"good."

At this time, Academician Cao said:

"Don't worry, this project can take a few months. Don't be too impatient. Your health is important. I see that you only turn off the lights in the room around two o'clock every night. Young people should take care of themselves."

Zhou Yi was stunned and said:

"Isn't it the same for you? Otherwise, how would you know that I went to bed so late?"

It's impossible for both of you to get the B test and think that someone else won't get the test.

The two looked at each other and smiled, and Zhou Yi returned to his room with the information.

But instead of looking at it the first time, we started to work on the second problem, which was the detection of water distribution on asphalt roads.

This issue is related to the future application of autonomous vehicles and trams.

After several days, Zhou Yi finally found some clues from the respective documents and data.

People who worked on this project before only considered that the mask circular convolutional neural network paid too much attention to the segmentation of the area when detecting and segmenting the water accumulation area, and ignored the problem of boundary segmentation.

How can this be done?

Zhou Yi exclaimed on the spot.

With these two issues resolved, I'm afraid this project will be completed within this month.

Just when Zhouyi was about to stay up late to do it, Mudan reminded:

"Master, tomorrow is the day for you to return to Yuzhou. Besides, it's already two o'clock in the evening, so you should go to bed early. According to scientific reports, sleeping after ten o'clock at night means staying up late. Master, please don't be young and willful, and take care of yourself as your own responsibility. .”

Zhou Yi was stunned for a moment. This artificially retarded man had read many papers and his intelligence had soared.

He even advised his master to take a rest early.

"Okay, I'll tell Academician Cao tomorrow and see what they think. I'll also grab a ticket for the day after tomorrow in case I get busy tomorrow and forget."

Zhou Yi said directly.

The next day, Zhou Yi didn't even go for a morning jog. He got up, washed up and finished eating, then went straight to Academician Cao's office.

As soon as Zhou Yi entered, he saw Academician Cao having breakfast and said:

"Cao Yuan, great discovery!"

Academician Cao quickly swallowed the egg in his mouth and said:

"What did you find?"

Not only Cao De looked at Zhou Yi, but Lu Zhonghua, Yuan Zhen and others also looked at Zhou Yi, hoping that Zhou Yi would make a big discovery.

Zhou Yi immediately said:

“People who worked on this project before only considered that the masked circular convolutional neural network paid too much attention to the segmentation of the area when detecting and segmenting water accumulation areas, and ignored the problem of boundary segmentation, which is not feasible.

It is necessary to add the Laplacian operator and use the boundary weighted loss function constructed based on it to establish an improved Mask R-CNN model.

At the same time, the residual network is used as the feature extraction network, using the transfer learning method, using 1753 self-built road water accumulation images for training, and using the weighted harmonic mean F1 and Jacquard coefficient of precision and recall as evaluation indicators. .

This is scientific! "

Zhou Yi said directly without taking a breath.

Not only Academician Cao was stunned, but everyone in the team was also stunned.

That’s the truth!

Lu Zhonghua on the side said immediately:

"We will start working on the new model now. If this problem is solved, our difficulties will be reduced by more than half."

Yuan Zhen and other doctors complained inwardly, Ma De, what a pervert.

It has only been ten days, and the most important problem has been solved, whether or not to be so perverted.

Son of mathematics?

Yuan Zhen shook his head, no, he can only be regarded as a young son of mathematics. Zhang Yitang, an old son of mathematics, now looks like an old son of mathematics.

If the Landau-Siegel zero point existed, the Riemann Hypothesis, known as the most difficult, would be cool.

If the time comes to exaggerate a bit, Zhang Yitang can directly become the greatest mathematician in the past fifty years.

Zhouyi said:

"I think it can be improved. We can make a rough outline first, and then use a large model to cover the entire paper, and design two mathematical models based on the evolution of space and time and the fatigue of the pavement structure."

In fact, Zhou Yi also had an idea, which was to analyze the material issues and see if he could make another breakthrough in physics and chemistry.

In this way, the various advantages of asphalt roads may be greatly expanded, not only extending their lifespan, but also a super qualitative change.

Yuan on the side exclaimed in shock,

"I'm afraid this is not just a matter of one or two top issues, but multiple top issues."

Cao De shouted:

"Compared to the top journals, the technical value of this paper is wealth. It can not only save hundreds of billions of dollars, but also benefit our country and people, you know.

How can academic matters be measured by top journals? "

Although Academician Cao said this, he could not hide the smile on his lips.

In addition to the core, the rest of the content is compiled into several papers, which can also be published in top journals in this direction.

By then, not only will the academic results be available, but the project will also be completed, and it will also be kept confidential.

Zhouyi said:

"Then my mission is completed?"

Academician Cao said:

"If you are willing to stay and help us deal with the follow-up problems, the rest of the tasks will be taken care of."

Zhou Yi shook his head,

This task does not involve any application of Hilbert's 18th question at all. At most, it may be used when it comes to algorithms. By then, it is not clear whether it can be regarded as an application of Zhouyi.

"No, as the New Year is approaching, I have to go back to spend time with my grandparents. They are getting old. If I don't accompany them often, I will have no chance in the future. They are my blood relatives."

Zhou Yi said.

The two old people suffered too much. They had to work from morning to night in order to support Zhou Yi's studies. In order to save a few dollars of bus fare, they had to walk more than ten kilometers to the bustling town next door to sell vegetables.

The food all year round is just white rice with pickles. I don't dare to cook an extra dish, even if it is a vegetarian dish, it is a luxury.

Seeing Zhou Yi's firm attitude, Academician Cao said:

"Well, the ideas you provided have already given us a big breakthrough. It doesn't matter if you help us with the follow-up."

Zhouyi said:

"Then I'll leave first. I've signed the electronic version of the contract for honorary professor of Dongda University and sent it to your email."

"Well, have a nice trip."

Cao De said.

"Well, I'll go back and sort out my things."

After Zhou Yi finished speaking, he returned to the room and packed his things.

Academician Cao said:

"The Book of Changes helped us solve an important part. This year, we have to work overtime and ask for leave if we need to go back. If it is not necessary, I suggest you stay and finish it one day earlier and lose one less day. One day costs more than 270 million. loss."

A loss of 270 million yuan in one day is terrifying when you think about it.

How much money would be made if this technology were sold to other countries?

According to Zhou Yi's thinking and their own thinking, the life span is conservatively estimated to be extended to 40 years.

Everyone said excitedly:

"good!"

Yuan Zhen is eager to publish a paper. He only has one paper left before he can graduate. Then he will definitely get a high salary from various companies. A doctorate in applied mathematics is still very popular in various companies.

I went to the hospital, but they didn’t let me in and required 48 hours of nucleic acid testing. It was embarrassing. The author thought it was 72 hours and I had to go there tomorrow, so the update might be a little later tomorrow. . .
