Hammer of Technology

So none of the transferred movie files could be opened.

Lucy Ron froze.

"Well, let me make an analogy. For example, my theory is as high as a ten-story building, and you probably only go around on the first floor, and you feel that you can do it. Let me guess, are you I stayed up late last night, packaged this thing all night, and then tested it casually. I saw that the effect was good, so I went to bed? Maybe I had a dream at night, and I saw your software in the dream A look of surprise?"

Ning Wei looked at Lucy Ron and asked, the mockery in his eyes was enough to drive people crazy.

However, Lucy Ron just pulled out the USB flash drive silently, then sat up straight and said, "Okay, then, may I ask the respected Professor Ningwei, what is my problem?"

"It's because you haven't finished reading my thesis at all. If you understand the theorem 13 proved by Lemma 17, Lemma 32 and Lemma 13 in the paper, you can judge that under the existing file storage format, there is no This kind of high-speed data migration is impossible. Without a pre-designed index comparison directory, the migrated data can only be a bunch of garbled characters. As I said earlier, if you can put the rigorous attitude of what party to go to and what evening dress to wear For science, your achievements are more than that. But unfortunately, you have never listened to my good words. What kind of rubbish is this written?" Ning Wei said.

"Okay, the time is almost up, Lucy, why don't we hurry up and take the two gentlemen to the venue. Maybe Professor Wilson is already in a hurry." Isabel, who had been by the side, suggested.

"Okay, wait while we pack up."

Speaking of which, Ning Wei took the initiative to help Yu Xingwei shut down the computer, and then walked into the room with Yu Xingwei.

"Mr. Xiao Ning, you have to be careful with this woman later. I think she's probably not emotionally stable right now." Yu Xingwei suggested.

"Let's not talk about this. Don't delete her software later. She probably doesn't have time to do encryption. Remember to save the code and study it carefully. You can send it to the members of the interest group after you go back. It is very valuable for learning. .” Ning Wei said in a low voice.

"Huh? Useful?" Yu Xingwei was stunned.

"How can it be useless? The test software in the laboratory only needs to be processed according to her code. Think about how much time it can save! Didn't I say it? Although she didn't understand most of it, a small part I must still understand it. Of course, big data needs to be migrated to the network, so these codes are far from enough, but if you can understand it, it will always be beneficial." Ning Wei explained casually.

"You have to admit that those Harvard professors didn't miss her. Although that woman occasionally behaves a little crazy, and her IQ jumps the line a lot of the time, she is indeed a genius."

Yu Xingwei remained silent, he was still too innocent!

So are people with high IQs calculating each other like this?No wonder Ning Wei rushed to shut down the laptop directly...

……

So on the way to the main venue of the conference, Ning Wei kept [-] points of vigilance, staying away from Lucy Ron, and then he probably didn't realize that, in this way, he got very close to Princess Isabel, and Yu Xing Wei was forced to walk next to the Harvard female genius.

Fortunately, Lucy Ron seemed to be hit and didn't pay attention to these.

And when the four of them came outside the main venue, something unexpected happened to Ning Wei. There were actually many reporters today. When he came, many flashing lights flashed at the same time.

At this moment, Isabel also seemed a little surprised, and stopped quickly, but it seemed a bit late...

------------

160 He is the Savior!

Ning Wei also reacted quickly, and walked with Yu Xingwei calmly, without thinking too much.After all, the last time he participated in the conference was the first session in the afternoon, and today he is going to make an opening report, so it is understandable that reporters are waiting.

After all, it is the world's top computer algorithm conference. It would be strange if there is not even a reporter before the opening report.

Fortunately, there were conference staff on the scene to control the order, and the reporters covering the science and technology conference were obviously not as fanatical as those star chasing reporters, so Ning Wei followed Yu Xingwei into the venue smoothly.

But Ning Wei finally felt the influence of a certain royal princess, because out of the corner of his eye, he could see that the reason why he could enter the venue so easily was not only the staff helping to maintain order, but also because this Princess Isabel attracted the attention of the audience. Help reporters get almost all of their attention.

The equally excellent Lucy Ron was also completely suppressed by Isabel's demeanor at this moment.

Well, this is probably the influence of the bloodline.

……

At nine o'clock in the morning, Ning Wei sat on the rostrum of the world's top conference again, feeling a little different from last time.

For example, there are more people in the audience. In the past half an hour, John Wilson has been introducing the other guests invited this time, and there are even doctors from Yanbei University and students from the opposite school. professors.

More importantly, he didn't have so many messy things in his mind when reporting this time, and of course he wasn't timid.I just inexplicably thought of the scene when I said goodbye to classmate Jiang the night before yesterday.

"Then... then you must win glory for the country when you go..."

Thinking of this sentence, he thought of what Jiang said when he turned his head: "Wait..."

I don't know what this girl wants to say to him...

Thinking of this, Ning Wei couldn't help but smile.

Just at this time, the host of the conference affairs group had finished his introduction and gestured at him to start.

The flash lights up just right, recording the smile on Ning Wei's face, a very classic photo.Because for many years afterwards, many people called it "the devil's smile".

"I believe that everyone has read my paper, and has a certain understanding of some of the mathematical ideas. In fact, the guiding significance of this paper in mathematics should be a deep analysis of the application of irrational numbers. For example One or several groups and arrays of irrational numbers established by constants such as π, e, and numbers with inexhaustible square roots, and through the most concise operations and certain transformations, these unordered irrational number segments can be fully expressed The information we need."

"Before discussing its overall idea, we must first determine a mathematical assumption, that is, irrational numbers can contain almost all information. Taking π as an example, each of us can find everyone's date of birth in π. If we With unlimited computing power, you can use the constant π to find a certain paragraph that can contain all the content of a Hamlet. Or intercept a certain paragraph that contains all the content of the 206-page paper I submitted to the conference.”

"So in theory, we only need to locate a two-dimensional starting coordinate and a two-dimensional ending coordinate to directly define a literary masterpiece, or a paper that put me on this stage. Of course, with the present From the perspective of computing power, all the computing power on the earth is counted for [-] million years, and it may not be possible to express the content of Hamlet with a single π."

"But after studying this paper, you should have learned that in the case of limited computing power, if we only use the characteristics of irrational numbers to perform lossless and high-speed compression on very large data, it is feasible. Most importantly, In theory, it is possible to recursively compress data almost infinitely, thereby fundamentally solving the problem of large data migration. This is probably why I am sitting here today."

"As I said at the conference last time, I studied mathematics at the undergraduate level, so I am not good at explaining these concepts in other ways, so next, I will try to let everyone understand with pure mathematical ideas and tools, How to realize this idea, first of all, we still construct a real number field..."

……

As soon as these words were spoken, there were inevitably some boos from the audience.

This is not the first time, Ning Wei said the same thing on stage last time, and then there were those 10 minutes that made countless people feel that life would be worse than death.Sure enough, it came again this time.

Fortunately, most of the young people who can come to the conference this time have spent nearly a month on Ningwei's paper. To paraphrase the professors, the first 192 pages of this paper are purely mathematical papers. If you can understand it, you understand it. If you don’t understand it, you can ask, but if you still don’t understand it after explaining it, then you probably don’t understand it.After all, at a certain stage in mathematics, you can only fight for talent.

Most of the people who can participate in this conference have no problem with the use of mathematical tools. For example, to prove that e is an irrational number, it is nothing more than to use the Taylor expansion of e^x to write e as a series, and then use simple number theory knowledge to disprove it , and finally proved that e is the limit of a sequence, and the mathematical tools used are nothing more than calculus, series theory, and Taylor expansion, which everyone has already learned.

But the reason why Ningwei's thesis can be called the foundation is because the various mathematical tools used in it were originally created by him. The step-by-step lemma proof is just to prove that the mathematical tools he proposed are correct. Using extremely complex mathematical tools to prove more complex problems is like a Russian nesting doll.

If one link is not understood, it is impossible to follow Ning Wei's train of thought to understand how the next link came to a conclusion.After all, he simply said, "It can be seen from this..." God knows how many steps were actually omitted in the middle.

In particular, the report meeting is only 10 to [-] minutes long, and there is not enough time to explain the most difficult part in detail. At most, we can only briefly explain the most difficult parts of the proof ideas.

So even if I have prepared for a month, I probably still don’t understand it. The difference from last time is probably that I can keep thinking “Although I don’t understand it, it sounds reasonable.” , "Maybe it should be understandable in this way?", "Maybe this is also feasible?", "Can it really be transformed like this? Why does it feel a bit strange?".

If I had to describe it, it would probably be that I have evolved from a completely incapable idiot to one who can do limited thinking.This raises another question, is it worthwhile to waste more than a month's vacation and spend time on a paper just to complete such a low-level evolution.

So all the thinking will probably be transformed into the same sentence in the end: "This shitty math!"

But this time everyone has to act thoughtful and take notes from time to time.After all, it was prepared a month in advance. If you still behave the same as last time, as if you didn’t understand anything, and take random pictures with your mobile phone, you will expose the fact that you are not very smart. This is all in the communication group. None of the young heroes can bear it.

So soon, when Ningwei's report was over and it was time for the questioning session, the group suddenly became lively, and the painting style began to become a little weird.

"I feel that this report will be very rewarding. Some things I didn't understand when I read the paper before suddenly became clear. It is really important to listen to the original author's thoughts on the paper."

"Well, I also have a similar feeling. For example, the previous space conversion principle is not so good. In fact, it can be understood by imagining these irrational arrays as different digital maps stacked together, and then calling them on demand."

"I deeply understand the good intentions of the boss. This month's time was not in vain. I was finally able to understand this report, and I was so excited that I burst into tears."

"Amazing! I feel like I'm about to forgive this undergraduate student. His speech just now opened a door to a new world for me. I feel that I have found the direction of my doctoral thesis."

"Yes, I just wanted to talk about my experience! I didn't expect everyone to feel the same. This direction is indeed promising! Think about it, if I can recurse a piece of data without redundancy ten times and compress it a thousand times, I will I can't help trembling! If I make achievements through these theories in the future, will I be called the father of super compression?"

Until some overly honest guy showed up.

"Please don't pretend all of you, can you? Do you really understand what he just said? And you have achieved results? The proof process of more than 80 lemmas and dozens of theorems is like a bible, that guy Just say that an hour can make you understand everything? Why can't I understand everything!"

"Guys who understand, let me test you with a question. Take the question that Ning Wei just explained as an example, Tp? {N, Z, R, S, L, B, H, P}, where Tp is a set of Data that is complete and cannot be decomposed without losing logical or semantic attributes... What steps are required for the basic classes and domains of all these data objects and their space transformation principles? How do they correspond to their spatial coordinate points? Who can follow now Let me explain? If you can explain clearly, I admit that I am a primary school student."

There was a moment of silence in the group, and then it immediately became lively again.

"Group leader, please kick the guy upstairs who obviously lowered the IQ of this group! Don't you understand? This theory alone can guide us to use the data without any redundancy under the limited computing power. It can perform several iterations of compression, not to mention the theoretical understanding of data transmission, which has at least surpassed all current compression algorithms."

"That is, I can't imagine that I have seriously discussed the functional issues involved in this paper with an idiot. Just think about it, a 206-page paper can be completed in a few dozen or less bytes. Express!"

"I always thought that all brothers and sisters in this group have basic mathematical literacy. Obviously, Luke doesn't have the same ability as most of us."

"This question is so simple that I don't want to waste time explaining it. It's unbelievable that such a basic question still doesn't understand."

"Second, let's kick it. He made me realize that the gap in IQ really cannot be made up through hard work."

……

So this time, a group of young people's speeches on Twitter also changed their style.

"Although this year's STOC has just finished the first report meeting, I can basically confirm that this must be the report meeting that I have gained the most. I am grateful to Ningwei, who made me see a new direction."

"It turns out that the idea of ​​mathematics is so profound. It's a pity that I didn't choose to go deeper in the field of mathematics, but I would rather this report let me see infinite possibilities for the future. What a wonderful idea of ​​mathematics!"

"It's an enlightening experience. Really, it would be a pity for countless people not to listen to this 10-minute lecture of STOC Ningwei Six. The brilliant mathematical ideas are so fascinating. Fortunately, I chose to give up my vacation to study this in advance. A paper, otherwise I will probably waste this precious opportunity again. Sure enough, if you pay, you will get something!"

"No matter how the conference selection team finally thinks about it, after listening to the report meeting, I have already decided in my heart that the best paper of this year's conference must be the paper of Ning Wei. I am grateful to Ning Wei, which made me appreciate the beauty of mathematics again."

"I didn't understand last time because I was completely unprepared, but in fact, after being prepared, I can find that it is a very happy thing to compete with the master's mind. It is no exaggeration to say that the Asian man has already used his The depth of thought conquered me!"

……

Ning Wei didn't know that he had become the savior of a group of young algorithm geniuses.

After simply answering the questions of the professors in the front row, his time for this conference has ended, and of course it can be said from another perspective that it has just begun.After all, this time Ning Wei participated in this conference, not only for the purpose of publishing papers.

Then there was a 10-minute break. After Ning Wei accepted the congratulations from several industry leaders in the front row, Yu Xingwei patted Ning Wei on the shoulder, pointed behind him, and whispered: "The one who showed you Check WeChat on your phone."

Ning Wei glanced back, and Lucy Ron shook his phone at him, with an inexplicable smile on his face.

Well, Ning Wei took out his phone from his pocket and looked at it, and then saw a bunch of screenshots of Twitter.

To be honest, this surprised Ning Wei a little.

What I said just a few minutes ago really touched this group of guys so much?He couldn't help but glanced at Yu Xingwei. Speaking of which, the two of them had been discussing together, why didn't they feel that this guy was so smart?Is IQ really flawed?

This made him unable to bear to share these screenshots with Yu Xingwei.

Yu Xingwei glanced at Ning Wei in surprise, then took the phone and started flipping through it one by one, his expression a little ugly.

"So you didn't feel that after listening to my speech just now, you suddenly understood it?" Ning Wei asked.

"No way, Mr. Ning, do you really think that what you just said is useful? How can you suddenly master it when you are less than a tenth of the detail in your lectures?" Yu Xingwei said with a bitter face.

"No, no, I think you should go and talk to these people at noon, maybe they really understand? By the way, you can also introduce the environment of Yanbei University to them, you understand." Ning Wei said.

Yu Xingwei nodded understandingly. In fact, it doesn't matter that he is not a genius, as long as he can lead a genius.He will still do such things as a fox pretending to be a tiger.

161 Perfect Soul SPA

There is a reason why the STOC conference is called the top conference in the world.After a 10-minute break, the second report will officially begin.

The one who gave the report on stage this time was Professor Robert Sandy, one of the students of Michael I Jordan, whom Ning Wei met yesterday.The title of the published paper is "Learning nonlinear operators via Deep ONet based on the universal approximation of the oremofoperators".

The content of the story is roughly that a neural network with a single hidden layer can accurately approximate any nonlinear continuous operator, and the general approximation theorem for operators implies the structure of deep neural networks when learning continuous operators or complex systems from scattered data streams and potential.

Very novel content, inspired by Professor Robert's research team, designed a deep operator network with small generalization error, which consists of a DNN for encoding the discrete input function space and another for encoding the output DNN composition of function domains, while demonstrating that the network can learn various explicit operators, such as integral and fractional Laplacian operators, as well as implicit operators representing deterministic and stochastic differential equations.

Professor Robert's report inspired Ning Wei so much that he had the urge to make a major change to the main program in March.

It was a kind of mysterious and mysterious feeling. Unlike his speech content, what Professor Robert talked about was mostly some very interesting data feedback that occurred during the verification process of the operator network, and naturally received bursts of applause.

Ning Wei didn't think there was much to this. After all, compared with this kind of achievable technology, the theory is always extremely boring, not to mention it is also a great inspiration to him.

In this way, after Professor Robert's report was completed, according to the schedule, the report meeting this morning came to an end.It's not time for dinner yet, but after listening to the two reports, we always need to leave some time for communication.

Of course, if you don’t want to go to the restaurant now and you still want to go, you can also go to the poster area, and you can have face-to-face communication when you encounter items you are interested in.

As a result, the poster area became lively. When Ning Wei walked out of the conference hall, he could already hear the voices of high-spirited talk.

"Then I'm going to find Brother Feng first?" Yu Xingwei said to Ning Wei who was beside him.

To meet Ning Wei's requirements, it is undoubtedly the fastest way to mingle with those young people and find Feng Shaojie.

"Well, go ahead, I won't attend the report meeting in the afternoon, we will have a meeting in the room at night." Ning Wei nodded and said.

The content of the report meeting just now is worth going through in his mind. By the way, he will find a place to study the thesis of Professor Robert Sandy just now. He has just obtained the complete printed version of the thesis through Professor Shen. Multiple pages of content.

There is still a while before dinner, if I go back to the room, I will come down later.

He vaguely remembered that there was a coffee shop on the way from the hotel to the conference center, which was opened in the passageway, and it looked quite quiet and stylish, so Ning Wei took the paper and walked towards the coffee shop according to the clues in his memory. .

It turns out that he thinks too much.

Many people probably had the same mentality as him. After the report meeting, they all gathered in the coffee shop, and some people in twos and threes gathered together to chat about some problems.When Ning Wei walked into the coffee shop, he immediately received a lot of glances, and some people nodded to him in a friendly way, and Ning Wei also smiled and nodded slightly in return.

Fortunately, he didn't come too late, and there was still space available.

Ning Wei chose a position next to the big glass next to the corner, spread out the paper on the table, and began to read it carefully.

"Excuse me?"

When a clear female voice sounded beside him, Ning Wei happened to read through the paper, and when he looked up, he saw Isabel pointing to the place next to him.

Ning Wei raised his head and looked around. There seemed to be no more seats in the coffee shop, so he nodded and said, "It's okay, please sit down."

"Still busy with research papers?" Isabel, who was sitting opposite Ning Wei, asked curiously.
