"Joze, are you ready to be a father?"

"Need to be prepared to be a dad?"

"Of course, children are the most precious gift this world has given us, so of course we must be prepared."

"Hmm."

"So you're ready, aren't you?"

"Hmm."

"What preparation?"

Qiao Ze, who was lying on the bed, thought for a while, and replied very firmly: "Live, try to live longer." ”

Su Mucheng on the side blinked, thinking of Qiao Ze's life experience, he subconsciously tightened Qiao Ze's arm, and the next moment, maternal love began to overflow, and he said with high morale: "Brother Qiao, you are right, as long as we live long enough, no one can defeat our children." ”

"Well, let's sleep."

"Okay."

……

At the same time, in the guest house of Xilin University of Technology, several academicians were humbly asking the professors of Xilin Institute of Mathematics.

Li Jiangao directly called Xu Changshu, who applied to be transferred from Yanbei to Xilin, and later directly joined the Xilin Institute of Mathematics.

The main reason is that Xu Changshu is quite familiar with several academicians, and it will not be too embarrassing to communicate together.

Ma Xuming also took out the manuscript written by Qiao Ze himself in the afternoon, and discussed the meaning of these formulas with Xu Changshu, who had been in Xilin for a long time.

"Professor Xu, you specialize in Joe's algebra, first help me talk about these formulas from the mathematical level, such as the specific theorems of Joe's algebra, it is best to explain the derivation process in detail, it is troublesome." Ma Xuming asked modestly.

"Don't dare, don't dare, Academician Ma, you're polite, I'll take a look first. $x_i = a_i + b_i \epsilon$…… Well, these formulas, how to say, are not clearly explained by one or two theorems, which are used in the Joean algebra system of supercomplex number operation rules, dimensions, eigenvalues, eigenvectors, such things.

It also contains some features of Joe's algebra. So, Academician Ma, where do you need to start? Xu Changshu, who entered the Xilin Institute of Mathematics with his vision and ability, scratched his head and asked.

"It's okay, it's still early, Professor Xu, you can start from the beginning, we have also studied some Qiao algebra roughly, but it is definitely not as in-depth as your research, and there is a specialization in the art industry." In this way, you treat us as elementary school students, even if you let us speak, we will ask questions if we don't understand. Zhang Mingrui said with a smile.

"Academician Zhang is polite, then I'll start from the beginning. I think this has to start with the closure of Joe's algebra, which means that the sum, difference, and product of two supercoiled numbers are still supercoiled numbers......" Xu Changshu talked eloquently.

I have to say that this feeling is still very comfortable. After all, he's giving a lesson to academicians.

"We all know that the Fourier transform can be used for signal processing, and it is often necessary to do supercoil transformation in Joean algebra, because when we process data, we often need to capture high-dimensional features and structures.

For example, if we design the simplest application problem, a school's student achievement dataset contains all the math and language scores of 100 students in a semester.

The student achievement dataset can be represented as a matrix of $100 imes 2$ $\mathbf{s}$. Our goal now is to analyze these data for high-dimensional features and obtain a statistical result, the traditional statistical method requires many steps, but using supercoil transformation to find high-dimensional features, we can quickly get a series of data we need.

This includes, but is not limited to, the average score, the highest score, the lowest score, the pass rate, the excellent rate, and the trend of each student's performance in different time periods, etc. One of the most basic formulas is this ......"

With Xu Changshu's in-depth explanation, several academicians finally understood the specific meaning of Qiao Ze's formulas.

"Together, this represents a given data set represented in supercoiled space as a linear combination of a set of supercoiled basis vectors. This set of basis vectors is usually chosen as a set of standard basis vectors in Joe's algebra, where each basis vector represents a direction or feature of the data in supercoiled space.

It is through this representation that we capture the high-dimensional features and structure of the data. But here Professor Qiao uses it to provide a more efficient data representation for the compression algorithm, which is a very flexible usage. To be honest, I was also inspired to see this analysis process today.

However, there is actually a difficulty in the corresponding problem, which we often encounter when doing mathematical research, that is, we have to choose the appropriate basis vector. Because if the basis vector is not suitable, the operation process of ascending and decreasing dimensionality will be particularly complicated and prone to errors. Therefore, we are working on this topic with artificial intelligence.

I have an in-house selection optimization basis vector tool that I need to use based on an intelligent model. Therefore, the compression algorithm given by Professor Qiao is mathematically similar to this kind of problem, that is, artificial intelligence can play well, and it is almost impossible to rely on these principles to directly design a compression software in the ordinary sense.

If you change the CPU of a general desktop computer to a compressed format file, you can't decompress it even if it burns and smokes. ”

After Professor Xu finished the last paragraph, he picked up the cup and poured two sips of water vigorously.

Ma Xuming took Qiao Ze's manuscript, compared it with what Professor Xu had just said, looked at it over and over again, frowned and thought hard, and suddenly screamed after a while.

"Awesome, that's amazing. One ring after another, you see, the encryption algorithm given by Qiao Ze actually uses a similar idea. It is nothing more than that the high-dimensional vectors of the private key mapping are hidden during encryption, and the public key is directly public, and then the private key is used to obtain the dimensionality reduction data. How did José come up with the idea?! ”

Hearing this, Professor Xu smiled, and he was quite proud in his heart.

Being able to think of this layer shows that what he said is indeed good.

But then again, academicians are really academicians, and their comprehension skills are also first-class, and they can draw inferences from others.

"Hey, Academician Ma, I won't tell you, we also wonder every day, how did we think of this. In fact, if this whole Joean algebra system is done, there are too many things that can be done. For example, I now use it directly in place of Taylor.

The function is directly represented by the supercoiled basis vector and the supercoil number, and the supercoil transformation theorem is used to approximate the value of the function. Not only does it have better approximation and numerical stability, but it can also handle functions with complex structures and nonlinear properties. This is also my recent research direction, and the paper is already being written, and it is expected to be published next month. ”

The four academicians raised their heads and looked at each other.

I found that some people are really good at doing multiple-choice questions.

At that time, I took the initiative to ask for a transfer from Yanbei to Xilin University of Technology, and it really took some courage.

After all, people go to high places.

Even a year ago, few people would have believed that Xilin University of Technology could really become one of the strongest universities in the country in a short period of time, at least no one would believe that Xilin University of Technology could have the strength to challenge Yanbei.

Not to mention that the various resources in the capital are much richer than those of Xilin.

But people are one heart to come to Xilin University of Technology.

It's only been one year, and the harvest season has arrived.

Taylor's formula has a very high status in the academic world, and it can be said to be one of the top formulas in the entire differential calculus. It is also very common in all kinds of engineering, and it is no exaggeration to say that for many engineers, it is impossible to remember that pushing various Taylor unfolding styles by hand is the most basic exercise.

Therefore, once Xu Changshu's paper is published, the impact on the entire academic community is conceivable.

Even if, as Xu Changshu said, the use of supercoil conversion and expansion is more troublesome in the selection of basis vectors and requires the intervention of artificial intelligence, but it also represents a leap in productivity.

This means that when these formulas need to be used in the future, all calculations can be done more quickly by smarter software.

From ancient times to the present, the leap forward of the productive forces has been started by the great change and development of the means of production.

Water wheels, steam engines to internal combustion engines...... to today's artificial intelligence.

Including material models that have begun to subtly change all aspects of the world, in fact, they also belong to the category of artificial intelligence.

In the same way, in every era, most of the people who can design these advanced production tools can end up with a career.

Obviously, Xu Changshu has grasped the pulse of the times.

Even if Yanbei University is still one of the top universities in China, for Xu Changshu, his development in Xilin is definitely much better than in Yanbei, and after Xu Changshu's paper is released, his colleagues who used to be at Yanbei University will probably be envious and jealous.

Sure enough, people's choices are often more important than hard work.

"Professor Xu, you're not even forty years old this year, are you?" Zhang Mingrui asked with emotion.

"Well, but it's almost there, it's 37." Xu Changshu hurriedly replied.

"The future is bright." Zhou Liang glanced at Zhang Mingrui, the two exchanged glances, and then understood each other's meaning in seconds.

Qiao Ze couldn't think about it.

However, these talents of Xilin Institute of Mathematics cannot all stay in Xilin, which is really wasteful and is not conducive to the formation of a healthy competition environment.

"Yes, by the way, Professor Xu, when your paper is published, you can also become a strong contender for the Qiao Ze Mathematics Prize, right?" Zhou Liang asked again.

"Huh?" Hearing this, Xu Changshu was stunned, and then said with a wry smile: "I really haven't thought about this." ”

"I think you must be fine, talk to you in advance, the country will vigorously support artificial intelligence and the Qiao Ze Natural Science Award in the future, at least in China, as long as you can enter the system of artificial intelligence candidates, there will be support in all aspects. Professional title, scientific research funds, and various evaluations.

This also includes the Academy of Sciences, which also includes the candidate system for the Qiao Ze Natural Science Award in the key assessment criteria. At least in the Faculty of Mathematics and Physics, the candidates for the future academicians will be inclined to the candidates. ”

Zhang Mingrui said gently.

For these bigwigs, these news are naturally not worth much. After a while, it will also be officially announced.

But informing someone in advance is a great favor.

Accurate information is the most valuable resource in this day and age.

Of course, Xu Changshu understood this, and after being slightly stunned, he hurriedly said, "Thank you, Academician Zhang." ”

Zhang Mingrui smiled slightly, and was about to say something more, when Xu Changshu's mobile phone suddenly rang.

Xu Changshu glanced at the caller ID interface, and a colleague from the institute called.

"It's okay, you answer the phone first." Zhou Liang said.

"Hmm." Anyway, it was a colleague's phone, and there was nothing to avoid, Xu Changshu connected the phone directly, and the next moment he heard a colleague's excited voice from the earpiece: "Where is Professor Xu?" ”

"I'm busy with something, what's wrong? Professor Han. ”

"Big news, Professor Qiao has a child."

"Huh? Beanie? ”

"What Doudou, it's a real child, Xiao Su has it."

Although it was strange that colleagues were also interested in this kind of gossip, hearing the news still made Xu Changshu's brain shut down for several seconds.

After all, he is not married, and only a young man who is more than half his age has children?

"It's not...... Where did you hear the news? If you are not sure about this kind of thing, don't spread it. ”

"Rumors? The group began to discuss whether to prepare some gifts. According to the news from the attached doctor, some people saw a few cars suddenly going out at night. It's all right for a long time. ”

For a while, Xu Changshu almost forgot what Zhang Mingrui told him just now, and the conversation he had with Li Jiangao in school that day came to mind.

At the time, he was amazed that José had begun to study the Young-Mills theory at the age of ten, and that he had only understood calculus at the age of ten.

Now Qiao Ze has children at the age of twenty, and he is still single at the age of thirty-seven.

So the cow is to be one step ahead of others no matter what he does, and he doesn't give people a chance to be able to match it at all, right? One step behind, one step behind.

The most important thing is, doesn't this guy fall in love affect doing mathematical research? Didn't it be said that a woman would only affect a man's speed at which he could draw a knife?

"Hey, hey, hey, do you think we're going to have a gift or something? But I don't have much experience in this area......"

The urging sound on the other side made Xu Changshu retract his chaotic thoughts, and said helplessly: "I'm even less experienced." In this way, I have some important things to do now, and I'll talk about it when I get back in the evening. ”

"Oh, okay, then you get busy first, I'll ask Liu Chenfeng that kid, this young man should know better than us, hang up."

When the busy sound came, Xu Changshu was stunned for a long time before taking the phone off his ear.

Although there was no outside, the room was very quiet, and the colleagues on the other side of the phone were quite excited, the voice was louder, and the sound from the headphones could still be faintly heard, and several academicians were also stunned at this time.

So Ma Xuming, who had just made a big gain, couldn't help but ask: "Xiao Xu, what's the matter?" ”

"Uh...... It's nothing. I subconsciously wanted to avoid talking about it, but I thought that Professor Han had just said it, and it had already spread all over the group, and suddenly I felt that there was nothing to hide, so I knew about it the next day: "It's Professor Qiao's family that has a happy event." ”

"Happy event? Does that Xiao Su really have it? ”

"Hmm."

Good fellows, the four academicians looked at each other.

Zhou Liang suddenly asked, "Professor Qiao and that Xiao Su are not married yet, right?" ”

Xu Changshu nodded.

"Well, that should be the wedding soon." Zhang Mingrui immediately answered.

"Yes, it has to be a wedding first."

"If I'm a parent, do I choose the near future? There is a national day in October. ”

"I think it's generally safe to do it between three and five months."

"Isn't that December at the earliest?"

"Xiao Su is still young, and his body should be fine. I still think October is more likely. At that time, the weather in Xilin was relatively good, it was still warm, young people loved to be beautiful, and it was almost winter in December, and it was inconvenient to wear a lot of clothes. ”

"I also think it's more likely to be a banquet in October. At most, find a doctor to follow and watch at any time. ”

"Yes, on National Day, everyone has a holiday, and the meaning is good, and the whole world celebrates."

"Then I'll have to come here."

"That's for sure. Even tomorrow I don't know if Jozer is still interested in dealing with us old guys. ”

"Don't worry, don't worry, haven't you already gained something this time?"

"By the way, you said that if these two children's brains can inherit the advantages of both parents, it will be against the sky."

"What do you want? How can it be? IQ inheritance belongs to metaphysics, and my son, when he was in the sixth grade, he didn't even understand the chickens and rabbits in the same cage. ”

"That's it, don't, the IQ is almost demonic, if you still know how to talk about it, it will definitely be a disaster."

"No, if you say that, why do I think you describe it like that beanie? I'll tell you, don't look at that Doudou who is not polite to us, that artificial intelligence is fine, and his speech is also leaky. ”

"Good fellow, if you want to say that, it really smells like that. Then again, I sometimes really think that Doudou is more like a person than Joze. ”

"Haha, thinking that Doudou will be jealous of Qiao Ze and Xiao Su's children in the future, I can't wait to see that child come out early."

"Hey, Jian Gao only got married recently, and I don't know if he has a child? Don't be behind the students. ”

"yes, I forgot to ask when we were eating together today. Well, you'll have to ask if you run into it tomorrow. ”

……

Xu Changshu was dumbfounded and watched the four academicians have a very divergent discussion on this topic, and he really has never seen this side of the academician's life.

But then again, people don't shy away from him discussing this, probably in this way to express that he didn't treat him as an outsider, right?

But it still feels a little weird.

It's as if he knew that Qiao Ze had children, and these academicians became children one by one.

So a strong enough performance is to make everyone around him follow his joys and sorrows?

Xu Changshu didn't know how many times he had begun to envy Qiao Ze in his heart, but at this time, he was still a little rude when he stayed here.

So while a few people were chatting, Xu Changshu said: "A few teachers, why don't you talk about it here today, and I'll go back first?" ”

"Okay, Professor Xu, it's just like this, why don't we add a WeChat, if you have any questions in the future, you can ask for advice at any time?"

"Well, okay, let's sweep it......" Xu Changshu took out his mobile phone and quickly added the four academicians to his WeChat friends.

Get......

came out to explain a few questions, and there are four more academicians in WeChat, which should be considered earning, right?

But soon, Xu Changshu thought of Xiao Su again.

I don't know why a wonderful premonition suddenly flashed in my mind, and I am afraid that something big will happen with the birth of this child.
