From small town scholar to chief scientist

Chapter 175 The Great Breakthrough

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

Around seven o'clock, Zhou Yi finished his morning run, returned to his room, made some food and went directly to the office with the materials.

Zhou Yi was already very familiar with the round-trip route, and it was impossible for him not to know the way.

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

It stands to reason that the postgraduate entrance examination and the final exam have also ended. There should not be so many talents in this time period.

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

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

For example, Mr. Zhang Yitang, with years of hard work, announced at the ZOOM meeting on October 300 last year, under the witness of more than [-] people, that he had solved the zero point (Landau-Siege) conjecture.

Once the review is passed, the effect will be no less than Zhou Yi's announcement to prove the 3n+1 conjecture in Lecture Hall [-] of the Institute for Advanced Study in Princeton.

Its importance is not known how many times greater than the 3n+1 conjecture.

Really old and strong, very brave.

The bowl of mathematics depends too much on age. The older you are, the worse your imagination for mathematics will be. Except for enough skills to make up for it, it is hard to imagine that there will be such a big achievement.

Concentration for many years, only a few people in this world can do it.

Not long after, Zhou Yi came to the office, as expected, there were no empty seats, only Zhou Yi came the latest.

Zhou Yi said awkwardly:

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

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

Academician Cao said very politely.

Lu Zhonghua asked:
"Have Professor Zhou eaten breakfast, and didn't ask Yuan Zhen to buy one for you?"

Yuan Zhen on the side looked numb, running errands was already a routine for him.

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

Zhou Yi said straight to the point.

Academician Cao smiled and said:
"Don't be in a hurry, God Zhou will get acquainted with it in the past few days. The information about physics and chemistry you asked for before will be delivered in the afternoon."

Zhou Yi said:

"Okay, anyway, I didn't finish reading the information last night, so I'll read it again this morning, and 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 No.18 question must be used to complete it.

So far, Zhou Yi has not discovered in which aspect Hilbert's No.18 question can be applied.

You can only look at their information and data more.

With so many directions, Zhou Yi felt that he could always find a few tasks that belonged to him.

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

The documents and materials in the USB flash drive were also passed in.

Zhou Yi browsed all morning, read a lot, and finally chose two directions.

At this time Yuan Zhen asked:
"God Zhou, we ordered takeaway for lunch, do you eat here or go to the cafeteria?"

Zhou Yi said:

"Just eat here. I am going to choose two problems to analyze, the detection of water distribution in the area of ​​asphalt pavement and the analysis of the drainage strength of asphalt pavement in the regression model. These two problems seem to overlap. There are some problems with the model. I plan to start from this direction. Start."

Zhou Yi said to Academician Cao while reading the information.

Academician Cao said:
"Well, we are responsible for other tasks. The tasks in this direction are quite interesting, and they will promote the application of unmanned vehicles to a certain extent."

Zhou Yi said:

"That's right, I'm going to study it carefully just because of this point, and the solution to this part will greatly advance the progress of the project."

After lunch, it wasn't until after four o'clock in the afternoon that Zhou Yi needed materials about physics and chemistry before sending them over.

At this time Zhou Yi got up and said:
"Then I'll go back to my room to retreat first, and I will give a more reliable model as soon as possible regarding the results in mathematics."

Everyone has long been familiar with it.

Academician Cao said:
"it is good."

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

Then I turned on the computer and entered it.

In just ten or so days, it is definitely a problem that cannot be thoroughly studied.

It is no small success to be able to barely combine the models of the two problems.

For several days in a row, Zhou Yi found out that the model in the direction of the regression model for the analysis of the drainage strength of the asphalt pavement is indeed not very accurate.

The result of his thesis was to use the regression model to express the factors affecting the drainage intensity, and concluded that the thickness of the drainage layer structure and the slope of the road crown slope showed a linear relationship.
However, Zhou Yi's intuition may not be that simple.

At least one variable has to be considered to be meaningful for practical application.

Zhou Yi thought for a while, and then kept checking various information,
Finally, I feel that there is a causal relationship with the drainage intensity.

The regression model is built 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, I collected 40 pieces of data comprehensively, divided the training set and test set according to 8:2, performed 500 iterations, and gave me a reliable result, but I think this data and model are still unreliable."

After a while, 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 of 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, and there is always something wrong."

Peony said at this time:
"Mathematics is a delicate duck, but the master is too suspicious."

Zhou Yi murmured:
"yes."

"What does the relationship between porosity of asphalt mixture and drainage strength look like."

At this time, Peony spoke from the laptop and said:
"It's an exponential relationship."

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

Zhou Yi said:

"This is a bit scientific, but if there are no mistakes in mathematics, there is no problem."

After the simplest problem was solved, Zhou Yi let out a sigh of relief and said:
"It will be compiled into a new paper at night, and it can be sent to Academician Cao. The next step is the highlight, and I don't know what step they have achieved."

After Zhou Yi simply finished his meal, he went straight to the office.

"Hello, Professor Zhou."

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

Zhou Yi said:

"I have solved one of the problems. You can see if there is anything that needs to be added. I feel that this model is too idealized, and there is always something missing."

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

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

"We'll give you a message the day after tomorrow at the latest. We've done almost the same here, and we feel that something is missing. You can also take a look at the various models we made, and let's take a look at each other."

Zhou Yi said:

"it is good."

At this time, Academician Cao said:
"Don't worry, this project can be done for a few months. Don't be too stubborn. Your health is important. I think you don't turn off the lights in your room until around two o'clock every night. Young people should take care of their health."

Zhou Yi was taken aback, and said:
"Aren't you the same? Otherwise, how do you know that I go to bed so late?"

It's impossible for the same B paper to think that others don't.

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

But I didn't look at it for the first time, but started to work on the second problem, the water distribution detection of the asphalt pavement area.

This problem is related to the application of unmanned vehicles and trams in the future.

After several days in a row, Zhou Yi saw a little way from his respective documents and data.

The 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 the water accumulation area, and ignored the problem of boundary segmentation.

How can this nima do it?

Zhou Yi exclaimed on the spot.

With the resolution of the two problems, I am afraid that this project will be completed within this month.

Just when Zhou Yi was about to stay up late to do it, Peony reminded:
"Master, tomorrow is the day for you to return to Yuzhou. Besides, it is already two o'clock in the evening, so you should go to bed early. According to scientific reports, if you go to bed after ten o'clock in the evening, you will stay up late. Please don't be young and self-willed, and take care of your health as your duty." .”

Zhou Yi was stunned for a moment. This artificial mentally handicapped man had read a lot of papers, and his intelligence soared.

He even advised the master to rest early.

"Okay, I'll tell Academician Cao tomorrow to see what they think, and grab another 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 run in the morning. After washing up and eating, he went straight to Academician Cao's office.

As soon as Zhou Yi entered, he saw Academician Cao who was 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 all looked at Zhou Yi, hoping that Zhou Yi would make a big discovery.

Zhou Yi immediately said:

"The 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 the waterlogged area, and ignored the problem of boundary segmentation. This is not acceptable.

It is necessary to add the Laplacian operator, use it as a benchmark to build a boundary weighted loss function, and build an improved Mask R-CNN model.

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

This is science! "

Zhou Yi didn't take a breath and said directly.

Not only Academician Cao was stunned, but the entire team was stunned.

This is the truth!

Lu Zhonghua on the side immediately said:
"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 in their hearts, Ma De, it's really abnormal.

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

Son of Math?

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

If the Landau-Siegel zero point exists, known as the most difficult Riemann conjecture, it can be cool.

When the time comes to exaggerate a bit, Zhang Yitang can directly become the greatest mathematician in the past 50 years.

Zhou Yi said:

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

In fact, Zhouyi has another idea, which is to analyze the material problem in it, and see if another breakthrough can be made in physics and chemistry.

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

Yuan Shocked on the side exhaled,
"I'm afraid this is not just a matter of one or two top publications, but many top publications."

Cao De shouted:

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

How can academic matters be measured by top journals? "

Although Academician Cao said that, he couldn't hide the smile on the corner of his mouth.

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

At that time, not only will the academic results be available, but the project will also be completed, and it will also be kept confidential.

Zhou Yi said:

"Then my mission is complete?"

Academician Cao said:
"If you are willing to stay and help us deal with the follow-up issues, there will be other tasks."

Zhou Yi shook his head,

This task does not involve any application of Hilbert's No.18 question at all. At most, it may use some algorithms when it involves algorithms.

"No, it's approaching the end of the year, and I have to go back to accompany my grandparents. They are old, and if I don't accompany them often, there will be no chance in the future. They are my blood relatives."

Zhou Yi said.

The two old people suffered too much. At the beginning, they had to work for Zhou Yi to study, but they worked from morning to night. In order to save a few dollars in bus fare, they had to walk more than ten kilometers to the bustling town next door to sell vegetables.

The perennial meals are just white rice with pickled vegetables, and I dare not make an extra dish, even if it is a vegetarian dish, it is a luxury.

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

"Well, just the idea you provided has given us a big breakthrough, and it doesn't matter if you help us with the follow-up."

Zhou Yi said:

"Then I'll go first. I've signed the electronic version of the honorary professor's contract at Dongdae University and sent it to your mailbox."

"Okay, good wind."

Cao De said.

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

After Zhou Yi finished speaking, he went back to his room and organized his things.

Academician Cao said:

"Zhouyi 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 to stay and finish it one day earlier, so as to save one day from loss. One day is worth more than 2.7 million yuan. loss."

A loss of 2.7 million yuan a day is terrifying when you think about it.

How much will it earn if this technology is sold to other countries?
According to Zhou Yi's thinking and their own thinking, it is conservatively estimated that the life expectancy will be extended to 40 years.

Everyone said excitedly:

"it is good!"

Yuan Zhen is eager to publish a thesis, and he can graduate with only one thesis, and then go to various companies to definitely get a high salary. Doing a doctorate in applied mathematics is still very popular in various companies.

　I went to the hospital, but I was not allowed to go in. It took 48 hours for nucleic acid, which was embarrassing. The author thought it was 72 hours, and I had to go again tomorrow, so tomorrow's update may be later. . .
