From a university student to a chief academician

Chapter 69 Conquering the Professors of Kyoto Institute of Technology

"Ye Fei, this is how things are now."

After Professor Yang came out of the principal's office, he called Ye Fei and explained the matter.

After pondering for a moment, Ye Fei said: "Professor Yang, now that means, let me go to your school to show my ability before allowing the relocation of the laboratory, right?"

"Yes."

Ye Fei asked suspiciously: "Professor Yang, I am very puzzled. Is the principal of your school so easy to talk? The laboratory was relocated so easily?"

Professor Yang smiled and said: "Isn't this forced? In fact, the principal also has a headache about laser research, so he gave me full authority to handle it a long time ago. Because of this, he agreed so easily after hearing my proposal. gone."

There was one more thing he didn't say.

The reason why the president of Kyoto Institute of Technology asked Ye Fei to show off his personal abilities was actually to find a way to step down.

Otherwise, the research has been unsuccessful, and he also has a headache.

"Okay!" Ye Fei said, "I don't have classes on Friday, and I will fly to Kyoto Institute of Technology this Friday morning."

"Okay, before you come by plane, send me a message, and I will pick you up."

"Okay!" Ye Fei said, "Do you need me to prepare anything?"

"You just need to show your Gaussian function when the time comes, and prepare for it in the next few days."

"Ok."

On Friday morning, Ye Fei flew to Kyoto.

As soon as he came out of the station, Ye Fei saw Professor Yang standing not far away.

"Professor Yang!" Ye Fei waved his hand in greeting.

After shaking hands with Professor Yang and saying hello, get in Professor Yang's car.

While driving, Professor Yang said, "Ye Fei, you have to be prepared. The people who come to the lecture this time are all authoritative experts in number theory and lasers."

"There is the dean of the School of Mathematics. He is an academician of the Xia Guo Academy of Sciences, a deputy director of the Number Theory Committee, the director of the Mersenne Prime Number Institute, and a member of the International Number Theory Association."

"There is also the honorary principal of the School of Mathematics. He is the vice-principal of the school, an academician of the Xia National Academy of Sciences, a fellow of the Beili National Mathematics Academy, a fellow of the Beili National Industrial and Applied Mathematics Society, and the vice president of the Southern University of Science and Technology."

In a university, there is a president and a chancellor.

The honorary principal is equivalent to holding the title of principal without the rights of principal.

Moreover, a person can be an honorary president in multiple universities, just like a person can be an honorary academician in multiple countries.

The title of monk is only known in North America and some European countries. It is called Follow internationally, which translates to the meaning of monk.

There is not much difference between a fellow and an academician, but strictly speaking, the selection requirements for a fellow are a little higher than for an academician.

Among them, the members of Beili Country have the highest gold content.

Afterwards, Professor Yang mentioned a few more people, all with very high positions.

Either the dean, or the honorary principal, or the director of a research institute.

But without exception, their positions are almost the same as academicians.

Ye Fei said with a bitter face: "Professor Yang, I feel a little guilty."

Professor Yang said with a smile: "Why are you guilty, don't be guilty, show your common sense, I believe in your ability, and you will definitely be able to conquer them."

Ye Fei asked suspiciously: "Professor Yang, I'm just doing an explanation session, why are there so many talented people here?"

"Hi!" Professor Yang said with a smile: "It's not that this matter has a greater impact. Think about it, moving the laboratory for you is very shocking, so many people came to listen with curiosity."

Ye Fei couldn't laugh or cry in his heart.

But think about it, yes, if I heard about it, I would be curious too.

What kind of character is it worth moving the laboratory for him.

Curiosity is the desire of human beings to explore, so there will definitely be many people to take a look.

An hour later, the car drove into Kyoto Institute of Technology!
At this time, many people were sitting in a classroom at Kyoto Institute of Technology.

These people are all over the age of 40, and they are talking to each other.

But listening to the content of the conversation, I spit out Ye Fei, the continuum hypothesis, set theory, number theory and Gaussian functions from time to time.

Ten minutes later!
Ye Fei and Professor Yang walked in, and everyone's eyes swept over Professor Yang and looked at Ye Fei.

When the two walked to the podium, Ye Fei was a little uncomfortable being watched by them, his heart was a little hairy, and his expression was a little stiff.

Professor Yang was also a little nervous, not because he was nervous because everyone saw him, but because he was nervous about the next test of Ye Fei.

After all, this is related to whether the laboratory will be relocated, and it is also related to the success or failure of his laser research.

Professor Yang said, "Everyone, this is Ye Fei."

Everyone nodded and looked at Ye Fei curiously.

They had only heard of Ye Fei before, but had never seen Ye Fei.

Professor Yang said: "I think you've all heard about it. The principal wants to test Ye Fei's ability in Gaussian functions, and everyone should help to investigate."

Everyone nodded slightly, agreeing with Professor Yang's remarks.

Professor Yang turned to look at Ye Fei and asked, "Ye Fei, are you okay?"

Ye Fei took a deep breath and let it out again, saying, "No problem."

Seeing that Ye Fei seemed nervous, everyone smiled.

The principal looked at Ye Fei, smiled lightly and said, "Ye Fei, don't be nervous, just treat us as your students."

"If your ability can conquer us, I agree to relocate the laboratory."

"If you can't conquer us, we won't embarrass you."

Ye Fei didn't offend them, and there was no conflict of interest between them, so they naturally wouldn't embarrass Ye Fei.

The rest of the people also looked at Ye Fei with encouraging eyes.

Ye Fei saw that there was no tension at the scene, and most of the tension in his heart was removed.

He nodded slightly, and said, "Hello everyone, I am Ye Fei, and I will explain the Gaussian function..."

"Today I mainly explain the Gaussian kernel function."

"Gaussian kernel function..." There was an uproar at the scene.

The mainstream research of Gaussian function is Gaussian function and normal distribution, Gaussian blur principle, Gaussian kernel function and Gaussian noise.

Among them, Gaussian function, normal distribution and Gaussian kernel function are theoretical research and the most difficult part.

Gaussian function and normal distribution are the most widely studied, some are simple and some are difficult.

The study of Gaussian kernel functions is difficult.

If we talk about Gaussian function and normal distribution, the lowest difficulty is 1 and the highest difficulty is 7.

For the Gaussian function, the lowest difficulty is 5 and the highest difficulty is 10.

The research threshold of Gaussian function and normal distribution is low, and the upper limit is also lower than that of Gaussian kernel function.

However, the research threshold of Gaussian kernel function is high, and the upper limit is also high.

Most people study theory, they study Gaussian function and normal distribution.

Few people study the Gaussian kernel function.

The Gaussian kernel function will only be studied if the Gaussian function and the normal distribution are thoroughly studied.

The reason why everyone is surprised is because looking around the world, few young people study the Gaussian kernel function.

Unless you just have an understanding of the Gaussian kernel function, you won't study it thoroughly.

But in the current scene, it seems unrealistic to give a speech on something that is only understood.

If Ye Feizhen can explain the Gaussian kernel function, it will be very difficult.

Professor Yang also looked at Ye Fei in astonishment. He didn't expect Ye Fei to give a speech on the Gaussian kernel function.

He thought that Ye Fei would only give speeches on Gaussian functions and normal distribution.

But he didn't say much, he thought, Ye Fei shouldn't be a reckless person, since he took out the Gaussian kernel function, he was naturally sure.

Ye Feidao: "My explanation is divided into two parts, which are the separability and locality of the Gaussian kernel function."

"According to the locality of the Gaussian kernel, select the global function and the Gaussian kernel to form the kernel function..."

Ye Fei found that the more he talked, the less nervous he felt. After more than ten minutes of speaking, he felt no tension at all, as if the experts, professors, and academicians in front of him were really his students.

"So it's like this..." The dean of the School of Mathematics nodded slightly: "It's a very novel point of view, using a vector machine to introduce a Gaussian kernel function, and using the VC dimension theory and the principle of structural risk minimization to select the Gaussian kernel radius and kernel penalty parameter C. "

Vector machine, the full name is called support vector machine, is one of the learning kernel function algorithms.

Ye Fei uses a vector machine to derive the Gaussian kernel function, which is a relatively clever method.

Others use the vector machine to learn the kernel function, but Ye Fei uses it to derive the kernel function.

Ye Feidao: "One of the known methods is to use the Joachims upper bound with one error as the kernel radius..."

The honorary dean was surprised: "Using Joachims' upper bound as the nuclear radius? It's really clever..."

There is an SVM mechanism in the support vector machine.

And the Joachims upper bound has the effect of improving the algorithm.

By improving the Joachims upper bound, the SVM mechanism can be improved.

This makes the support vector machine, which is already suitable for the Gaussian kernel function, more suitable for the Gaussian kernel function.

"Wonderful..." Many people said excitedly: "Why didn't I think of it!"

Then they were surprised that Ye Fei could think of this.

The principal looked around and saw that many people were excited and shocked. He wondered in his heart: "Could it be that Ye Fei spoke well?"

He didn't study mathematics, so he couldn't hear what Ye Fei said was good or bad.

The principal whispered to the dean of the School of Mathematics beside him, "Old Xu, did he speak well?"

Old Xu scolded softly: "Don't disturb me, listen carefully."

The headmaster looked confused, helpless in his heart: "Yeah, let's ask after listening!"

But he couldn't understand, and what he heard was like chewing wax, which was boring.

Half an hour later, Ye Fei said: "After projection, a threshold is determined, and the original can be classified."

"My explanation is over, thank you everyone!"

After speaking, Ye Fei bowed to everyone.

"It's over?" Dean Xu was stunned, took out his phone to check the time, and actually listened for nearly an hour.

"So fast?" He shook his head slightly, thinking: "Sure enough, the happy time passes quickly."

Then everyone stood up and gave a big round of applause.

"Clap clap clap..."

After a while, the applause stopped, and the principal smiled at Ye Fei: "Ye Fei, wait a moment, we have a small meeting."

"En!" Ye Fei nodded slightly.

The principal said to everyone: "Everyone, let's find a place to discuss!"

Everyone nodded: "Okay!"

After speaking, everyone left here.

After sitting down in the next classroom, the principal said: "Everyone, you also know that I don't study mathematics, so tell me about the depth of Ye Fei's explanations!"

Everyone looked at each other, and the dean of the School of Mathematics first said: "Ye Fei's explanation is very eye-opening. I am surprised that he can have such a deep research on the Gaussian kernel function at this age."

"To be honest, I don't have such knowledge at his age."

"His current knowledge is equivalent to that of me at the age of 40, and even many of his views have made my eyes shine."

In the life of a general scholar, before the age of 35 is the learning stage, from 40 to 50 is the peak stage, and after fifty, it will go downhill.

It's not that the knowledge is not as good as before, but that the inspiration in the head is not as good as before.

Learning needs inspiration, and scientific research also needs inspiration.

In a person's life, the content of learning determines the starting point, and the inspiration determines the end point.

The headmaster was surprised, the height of this praise was too high.

He didn't think that Old Xu was flattering Ye Fei. He had worked with Old Xu for many years, and he knew what kind of character Old Xu was.

Old Xu has a serious personality, is straight-hearted, speaks frankly, and will never do flattering behavior.

Unless the person is really talented.

"Principal Lin, tell me." The principal looked at the honorary dean and said.

"Dean Xu is right." Principal Lin said: "Ye Fei's research on Gaussian kernel functions is very deep. I have been to many countries, even in universities such as MIT and Princeton in North America. Among the people who are more than [-] years old, there are very few people who have such in-depth research on the Gaussian kernel function."

A smile appeared on the corner of Principal Lin's mouth: "My country of Xia is about to produce a great mathematician."

President Lin, as a member of the North American Mathematical Society, has served in both MIT and Princeton. After comparing Ye Fei with students from MIT and Princeton.

He was surprised to find that Ye Fei was better than 99.99% of MIT and Princeton students.

You know, MIT is known as the world's strongest engineering university, and Princeton is known as the world's strongest science university.

The principal was surprised that this comment was higher than that given by the dean of the School of Mathematics.

The dean of the School of Mathematics compares Ye Fei with himself, and the honorary dean compares Ye Fei with scholars around the world.

The principal twitched his mouth and said, "Principal Lin, isn't your evaluation a bit high?"

The principal has not been in contact with Principal Lin for a short time, so he doesn't know Principal Lin's character.

Principal Lin shook his head: "No, not at all."

Dean Xu said: "I can testify to this point, Ye Fei is worthy of this evaluation."

The principal believed it when he saw what Dean Xu said.

But he still looked at the rest of the people and said, "Everyone, let's talk about it!"

Everyone talked in one go, all highly praised Ye Fei.

After a long time, the headmaster said: "Everyone, tell me, how helpful is Ye Fei's current ability to the research of laser weapons?"

Dean Xu said: "Judging from Ye Fei's current abilities, having him join the research on laser weapons is like adding wings to a tiger."

Principal Lin nodded: "That's true. Ye Fei has studied the Gaussian kernel function so deeply, and he has absolutely no problem in theory."

Everyone nodded, that's true. Based on Ye Fei's research on the Gaussian kernel function, there is absolutely no problem with the theory.

The principal said: "That is to say, there are no major problems in application?"

There is no problem in theory, but certainly not in application.

This is basic common sense.

"Yes!" Everyone nodded.

The headmaster took a deep breath, then let it out slowly, and said, "I see."

"That is to say, he joined the research of laser weapons and helped a lot, didn't he?"

"Yes!" Everyone nodded.

"Okay, I see." The principal smiled and said, "Thank you for coming today."

After exchanging pleasantries, everyone left.

The principal found Ye Fei and the two. Professor Yang stared at the principal closely and asked, "How is it? Do you agree to relocate the laboratory?"

The principal didn't answer immediately, but said, "Professor Yang, take Ye Fei to rest first, and come to me afterwards, I have something to talk to you about."

He smiled lightly at Ye Fei again: "Ye Fei, go rest with Professor Yang first."

"Good!" Ye Fei said.

Professor Yang suppressed the desire in his heart, took Ye Fei away, and then found Ye Fei a hotel near the school to stay in, and finally came to the principal's office.

"Come on, sit down!" The principal looked at Professor Yang who entered the door, and pointed to the sofa not far away.

After Professor Yang sat down, the principal asked the secretary to bring in two cups of tea.

Professor Yang sat on the sofa, clenched his fists, and stared at the principal anxiously.

Facing Professor Yang's eyes of seeking knowledge, the principal didn't hold back, and said, "I agree to move the laboratory."

Professor Yang heaved a sigh of relief, let go of his raised heart, and let go of his clenched fists.

"but……"

Professor Yang's heart skipped a beat, his heart rose again, and his fists were clenched.

"But I have a better proposal, without moving the lab."

"Principal, you..." Professor Yang said anxiously.

It was agreed to move the laboratory, but now we don't move, isn't this backfired!
"Listen to me!" The principal waved his hand to stop Professor Yang from continuing: "Since Ye Fei doesn't come to our school's laboratory and wants Ye Fei to do experiments, we don't have to move the laboratory."

"We can cooperate with Zhonghu University to jointly establish a laser laboratory, and at the same time leave the task to Zhonghu University."

"This kills two birds with one stone."

Professor Yang was astonished and said, "Principal, will the higher authorities agree to this?"

"Originally, we already have a laser laboratory here, and building another one at Zhonghu University, isn't that a waste of money?"

The principal smiled and said: "Actually, the higher-ups were planning to build this laboratory, but they were hesitating whether to build it in the National Defense University or Zhonghu University."

"It just so happened that we contributed to the flames and let the upper level be established at Zhonghu University."

"And we and Zhonghu University are established in the name of the joint, we don't spend money, and we can get a good reputation."

"And, most importantly, the hot potato of laser weapon research can be thrown to Zhonghu University."

He also just got this news, and Ye Fei just happened to happen, so he thought about helping Zhonghu University build a laboratory, and then throwing the laser weapon experiment to Zhonghu University.

"Then isn't it a waste of time for you to do what you did today?" Professor Yang looked at the principal in bewilderment.

The principal smiled and said: "We have given the task to Zhonghu University, and we should also inspect the strength of Zhonghu University. This is also the meaning of the above."

"Then my research?" Professor Yang asked anxiously.

Research is not just research, but research funding.

If the research is lost to Zhonghu University, the research funds must also be handed over.

"The above means that the funds will be retained to carry out other research, which is still laser-based, and the laser laboratory will do it."

"Huh..." Professor Yang let out a long breath, nodded and said, "That's okay."

He shook his head, and said with some amusement: "I didn't expect Zhonghu University to take advantage of it after a long time."

There is one more thing he didn't say, the principal is really an old fox.

Little effort was made to allow Zhonghu University to obtain a laboratory, and Kyoto Institute of Technology not only lost a hot potato, but also gained a good reputation.

Professor Yang thought to himself: "No wonder he can be the principal, but I'm just a researcher."
