Tech Hammer

An important idea for people to simplify complex things is to hand over the things that should be done by oneself. This is also the principle that Ningwei has always practiced, leaving things to others that cannot be done by oneself. This is something Ning Wei has already figured out when he was at Jiang University, that is, no matter how talented he is now, he cannot do everything by himself.

So at that time, he would package the semi-finished EDA software and turbulence algorithms and hand them over to Huawei; so after coming to Yanbei University, he would actively cooperate with Chen Mingcai and use the strength of others to build a laboratory he needs; so he would He roped in Senior Brother Lu to study artificial intelligence with him, and asked Yu Xingwei to follow him all the time; so he withstood the pressure and asked Lucy Rowan to be his teaching assistant, responsible for preparing papers for Ning class students...

In short, by letting the right people do the right things, they can be freed from tedious tasks and focus on resolving the main contradictions. For example, he solved the chip problem in the shortest time and designed and produced a three-dimensional silicon silicon tube chip, which once broke the shackles of chips on China's high-precision industries.

This time Ning Wei didn't think of finding someone to solve these problems because he and Tian Yan really had the same views. Of course, the initiative to choose students for oneself must be firmly controlled by oneself, so from the beginning, Ningwei had no intention of finding someone to choose students for himself, which was equivalent to entering a blind spot in his thinking.

After talking to Tian Yanzhen, Ning Wei realized that this matter could be left to March. It is true that these undergraduate graduates cannot be assessed like high school students, but from now until March next year, there is still nearly half a year for March to perfect a mathematical model to determine who is more suitable and has a stronger thirst for knowledge. The most important thing is It is March's choice that can definitely be impartial, and maybe it can also solve the common problem faced by almost all human societies for thousands of years - the problem of human relations.

Well, actually Ning Wei didn't think that far ahead. He simply thought that March could handle this embarrassing matter for him.

…

Jiang University, Maple Garden Building 3, Dormitory 108, four people are sitting at their desks studying. Since the dormitory was equipped with air conditioning, everyone is no longer willing to go to the library or occupy a seat in the classroom. When people go to the library to occupy a seat, they need that kind of study atmosphere, but that doesn't exist in the top student's dormitory.

The four people in the dormitory have already confirmed that they have obtained the exemption qualification. Two of them have already confirmed that they will go to graduate school at our school, and even their tutors have already made plans. One of the other two has roughly decided to go to Mingzhu Jiaotong University, and Ji Mingzhi has initially decided to go to Yanbei University for further study. The tutor has not been selected yet.

Even so, the four of them did not relax their demands on themselves. Although students who are exempted from admission do not have to take the preliminary test, they still have to pass the interview. Especially Ji Mingzhi, who is already interested in artificial intelligence, so he really hopes to be admitted to Ningwei's graduate school, which requires him to have higher requirements for himself. Now the whole world knows that he wants to be admitted to Ningwei's graduate school. It’s not easy, after all, there are too many declarations.

Fortunately, Ningwei does not recruit foreign graduate students. There have been rumors in the student circle that many graduates from Harvard, Columbia, and even Princeton hope to apply for Ningwei's graduate students. At least on Zhihu, many international students have spoken, saying that their professors are encouraging them that if they really want to engage in theoretical research on artificial intelligence or the metaverse in the future, going to Yanbei University is the best choice.

Therefore, Ji Mingzhi knew very well that he was now competing with the best undergraduates in China, so he did not dare to relax at all. One thing Kong Mingde didn't tell lies to Ning Wei was that Ji Mingzhi chose Jiang University because Ning Wei was his idol. Otherwise, he could have had better choices. Although he was still a little short of going to Yanbei University and Huaqing University, two super top universities, with his grades, it was not a big problem to go to Nanjing University or Fudan University.

At this time, he was studying Ning Wei's doctoral thesis. If you just read the thesis, you wouldn't be able to understand it. However, he has an internal reference material from Jiangsu University. It is said that many of the contents of this reference material came directly from Ning Wei's work. Manuscript at the time of writing this paper.

It's just said that it's not clear whether Ji Mingzhi is real or not. After all, the information sent to him was just printed information. But after all, Jiangda is Ning Wei's alma mater, and it is said that he has a good relationship with their dean, so it is not unusual to get the manuscript. However, Ji Mingzhi believes that this information is the result of the brainstorming of professors specializing in artificial intelligence at the school.

However, Ji Mingzhi really believes that only Jiang University can produce this information, because not everyone can have a fixed time every month to contact Ning Wei to discuss some academic issues. As we all know, Professor Ning is He is very busy, so busy that he does not even accept invitations from major universities in China to give lectures. Currently, Jiang University is probably the only one of the Chinese universities that has such a reputation.

In any case, this special relationship made Ji Mingzhi feel that he made the right choice during the college entrance examination. Otherwise, he would not have dared to think about the opportunity to study with Ning Wei in the future. After all, it was really too difficult, especially for college students. The machine classification and learning part of the data, those abstract correspondences, will really be confusing if there are no reference materials to explain the ideas in detail.

Really, even if you are a top student, when you see these papers for the first time, you can only sigh that this is the realm of gods. In addition to going to Yanbei University to participate in the summer camp this summer, Ji Mingzhi spent almost all his time researching this paper. Even with the help of reference materials, he only understood about half of the content, but for him It's like opening a door to a new world.

Whenever he gets tired of researching papers, Ji Mingzhi’s favorite thing to do is to look for those old posts on the Internet. Those posts describing Ning Wei’s presentations at two World Computer Algorithm Conferences two years ago, countless foreign academics posted on Facebook. , complaints and crying posts on Twitter, and the particularly long name they gave Ning Wei...

Every time he watched these, he felt fully immersed, as if he was sitting in the world's top conference giving a report and throwing out a proposition. As a result, the young and promising academics in the audience were all confused. She looked at him with a look of complete confusion...

Ji Mingzhi didn't know how Ning Wei felt at the beginning, but he felt that it must have been a great feeling. If you don't pretend to be cool, it's a waste of time! In particular, this is purely IQ crushing, and the pretentiousness in knowledge will invisibly elevate this level of prowess.

This is what we should do!

Finally, he figured out the proof of a lemma. Ji Mingzhi stretched out happily. He was about to pick up his mobile phone and browse the favorite forums to read the comments about Ning Wei on the Internet to wash his mind, but he ended up... He saw a notification on his phone that there was a new email in his mailbox, and the sender was...

"Wow! Professor Ning replied to my email!" Ji Mingzhi exclaimed in surprise.

The exclamation broke the quiet atmosphere in the dormitory. The other three people raised their heads almost at the same time and turned to look at Ji Mingzhi. After a moment of confusion, there was the sound of chair legs rubbing against the floor. Then the three roommates gathered. Behind Ji Mingzhi.

"Why are you still standing there? Open it quickly and take a look?!" someone urged.

"That's right, old plan, if you are really chosen by Professor Ning, you will really become rich. Don't forget each other if you want to be rich or noble!"

"Hey, Professor Xu said that Professor Ning will definitely be elected as an academician this year. It is almost certain. Lao Kong, the youngest academician student, and the first generation student of Academician Ning, if he succeeds Professor Ning You will probably be able to walk away from your mantle when you return to school... If our instructor treats us badly in the future, you have to speak for us!"

…

The envious and jealous words of the brothers in the dormitory did not reach Ji Mingzhi's ears at all. He had already rushed to the computer to log in to the mailbox, and the hand holding the mouse was trembling. Naturally, I feel a little nervous and a little scared, so don't just reject him directly.

After all, it's only September now, so there shouldn't be any news so soon.

I finally logged into the mailbox and saw the text of the letter.

"Classmate Ji Mingzhi: Hello, your letter has been received. Thank you very much for your recognition of my research. However, the mathematical theory of artificial intelligence is a research direction that requires creativity and imagination, and has high requirements for personal abilities. . The attachment to this letter contains my latest research experience. You can take a look at it first to determine whether you are really suitable for or like this research direction."

"If you have any questions when researching this paper, you can add a WeChat ID of SanNing00078632 and inform your school and name when adding. If you have any questions, try to describe the problem directly and clearly to facilitate mutual discussion. Finally, I wish Ji Mingzhi success in his studies. A long journey ahead."

The last signature was Ning Wei.

How should I put it? After reading this email, Ji Mingzhi was still very excited. He was even more grateful that he did not waste time during the summer vacation. Fortunately, he spent the whole summer studying Ning Wei's previous paper, and at least understood some concepts and worked on it. I understand some mathematical tools and I am somewhat prepared.

Of course, the most important thing is that this email means that he has most likely been included in the preliminary test list.

"Okay, Laoji, your opportunity has really come. This is obviously the final assessment. If you can understand Professor Ning's paper, you can really become an academician student." Congratulated the roommate.

"Professor Ning's paper is not so easy to understand." Ji Mingzhi said, the mouse has already clicked on the attachment download button, and the other hand directly picked up the phone, quickly opened WeChat, and added I picked up the WeChat ID left in the email and sent a friend request.

Soon, the paper was downloaded and opened. Sure enough, at a glance, you can tell that it is very difficult to understand.

For ordinary people who are not majoring in mathematics, there is a very counter-intuitive fact. In fact, after mathematics students come into contact with functionals, they will find that they can basically no longer deal with numbers at this level, and this is also the most difficult. Because you don’t need to do the math, but you have to deal with all kinds of extremely abstract spaces.

In the past, when people studied artificial intelligence, they didn’t actually need advanced mathematical knowledge, because deep learning often relied on composite function fitting. As a result, without the support of certain mathematical principles, everyone was adjusting parameters and needed to use pure numbers. Very little content. In most cases, you only need to master three courses: advanced algebra, mathematical analysis, and probability theory.

Advanced algebra and mathematical analysis are both papers that must be studied in the freshman year at Hony College, and probability theory is also something that has been exposed to in the sophomore year. None of these courses were difficult for Ji Mingzhi, after all, he got full grades in all three courses.

However, artificial intelligence began to become difficult at the mathematical level after Ning Wei began to study this direction. Of course, this is why everyone wants to hang out with Ning Wei.

Before the emergence of March, the development of artificial intelligence only stayed at the simple things in Euclidean space. At most, it sprouted the concept of manifolds, and even combined graphics with Lie algebra, but that was all.

When March appeared, Ning Wei began to match the machine thinking model with reality one-to-one in number theory, and complex spatial mathematical transformations in multiple spaces began to appear. This was no longer something that could be explained by three simple courses.

It involves complex mathematical tools, and obviously this paper proves a complex mathematical tool. But what surprised Ji Mingzhi was that this paper seemed to be in the same vein as Ning Wei's doctoral thesis he was studying. If this was an assessment, it would be really nice.

"Sure enough, it's very difficult. Hey, old plan, to be honest, although I'm quite jealous that you have such an opportunity, it's just you. I don't think anyone else is worthy of studying these things. In fact, I also wanted to test Ning. Professor Ning’s graduate student, but he gave up after reading Professor Ning’s thesis because he really couldn’t understand it!”

"Okay, Lao Liu, you're not bad at all. As long as you accept the fact that we are all still ordinary people, some things are actually quite easy to accept." Another roommate said with emotion.

This sentence made Ji Mingzhi feel more confident.

In fact, if you think about it carefully, who in Professor Ning’s academic career has been anything but an ordinary person? Ji Mingzhi believed that he was already outstanding among ordinary people, at least in their small group of Hongyi Academy, he was the best.

"Okay, okay, don't sigh. Let's study by ourselves. I'm also going to start studying Professor Ning's thesis. I don't know if I can become Professor Ning's student. Maybe I won't pass the exam." Mingzhi said with a smile.

"Old Ji, don't say anything discouraging. Anyway, I think you can do it. At least in our class, I will obey you."

"The revolution has not yet succeeded, comrades, keep working hard! Anyway, I have to study the paper!" Ji Mingzhi said with a wry smile.

Although he regained his fighting spirit because of this email, to be honest, looking at the colorful mathematical formulas on the paper aroused great interest in him and he was still a little nervous at the same time.

Mathematical formulas in other people's papers are everywhere, with various conditional probabilities changing, or some simple transformations, just to make the originally simple problem more complex, and to look like you are very good at it. But after studying Ning Wei’s papers, we know that Professor Ning’s papers have many formulas, but they are very restrained. Many conceptual things are difficult to restore in words. Only by converting these formulas can he convey them in the most concise way. thought of.

However, the roommates are obviously still unsatisfied.

"Wait a minute, let's see if Professor Ning applied through your WeChat first."

"Just take a look, old plan."

"Uh? Not so fast, right?" Ji Mingzhi said, then picked up the phone: "Huh? Did the application pass?"

"I'm going to say hello to my future mentor quickly."

"Farewell? Maybe Professor Ning is busy..."

"It's the right thing to say hello. If you're busy, you won't reply at most. What are you afraid of?"

"That's right, politeness is important, Laoji."

"Wait a minute, the WeChat ID is SanNing. Well, is it possible that this is not Professor Ning's WeChat ID? Maybe it is... you know."

"No way? It can't be March, right? Can we still discuss the details of the paper in March?"

"Tch, he was the best paper reviewer that year, and Professor Ning also said that the NS equation was actually proved in March!"

"I read online that the NS equation was actually proved by Professor Ning himself."

"You also said that it was said on the Internet. How many things said on the Internet are true?"

"Oh, you guys are arguing over nothing, Lao Ji. Why don't you just say hello first and you'll know?"

…

Well, the roommates were all in a state of excitement, which made Ji Mingzhi feel less confident.

After thinking about it, it shouldn't be a big question just to say hello, so Ji Mingzhi quickly edited a message and sent it.

"Hello, Professor Ning, I am Ji Mingzhi from the Hongyi School of Jiangnan University in 2020. Please give me your advice in the future."

The message came back soon, with text and pictures.

"Meow, Professor Ning?" The accompanying picture showed a smiling expression of a kitten holding its belly.

This... is a hammer... it really isn't Professor Ning...

Although Ning Wei is indeed very young, and there should be no generation gap with them in terms of communication methods, few of them can imagine Professor Ning sitting in the office, holding a mobile phone in his hand, looking for kitten emoticons to send to his students...

But this reply made several people in the dormitory excited.

"March, definitely March... Sure enough, it's not that simple for Professor Ning to select talents. Let's talk to March! This is March Bensan!"

"What should I call him? Professor March? Or just call him March?"

"Teaching assistant, Professor Ning Wei actually asked you to discuss any questions with him. You must be a teaching assistant."

Ji Mingzhi thought it made sense, and quickly replied: "Are you the assistant coach in March?"

"Meow, teaching assistant? You are the first one to call me that, classmate Ji. I am very optimistic about you. If you have any problems in the paper that you cannot solve, remember to contact me at any time. Now hurry up and study! Gulu!"

The text is followed by an animated picture of a kitten struggling to turn the pages of a book.

"Professor Ning is Professor Ning. The artificial intelligence program he designed is simply... simply... simply amazing..."

"Old Ji, come on, learn from Professor Ning. You can design a dog. Have you seen the photo of my Labrador? With that image, it will definitely become popular all over the world!"
