"Ye Fei, that's how things are now."

After Professor Yang came out of the president's office, he called Ye Fei to explain the matter.

Ye Fei pondered for a moment and said, "Professor Yang, now that means let me go to your school to show my abilities before I can allow the relocation of the laboratory, right?" ”

"Yes."

Ye Fei said suspiciously: "Professor Yang, I'm very puzzled, the principal of your school is so easy to speak?" So easy to relocate the lab? ”

Professor Yang smiled: "Isn't this forced? In fact, the principal also had a headache for laser research, so he handed it over to me a long time ago, and because of this, he agreed so easily after hearing my proposal. ”

There was one more sentence, which he didn't say.

The reason why the president of Kyoto University of Technology asked Ye Fei to show his personal ability was actually to find a step down.

Otherwise, the research has not been successful, and he also has a headache.

"Okay!" Ye Fei said: "I didn't have classes on Friday, and I will take a plane to Kyoto University of Technology this Friday morning." ”

"Okay, before you come on a plane, send me a message and I'll pick you up."

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

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

"Okay."

On Friday morning, Ye Fei took a plane to Kyoto.

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

"Professor Yang!" Ye Fei waved hello.

After shaking hands with Professor Yang, get into Professor Yang's car.

Professor Yang said while driving: "Ye Fei, you have to be prepared, the people who came to listen 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 Academy of Sciences, a vice director of the Number Theory Committee, the director of the Mason Institute of Prime Numbers, and a member of the International Society for Number Theory."

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

In a university, there are presidents and honorary presidents.

Honorary principals are equivalent to the title of principal, and have no rights as principals.

Moreover, a person can be an honorary president in more than one university, just as a person can be an honorary academician in multiple countries.

The title of monk is only found in Beili and some European countries, and 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 that of an academician.

Among them, the monks of the Northern Liberty Kingdom have the highest gold content.

After that, Professor Yang said a few more people, and their positions were very high.

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

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

Ye Fei said with a bitter face: "Professor Yang, I am a little weak-hearted. ”

Professor Yang smiled: "What is the weakness of the heart, don't be weak, take out the normal heart, I believe in your ability, you can definitely conquer them." ”

Ye Fei said suspiciously: "Professor Yang, I'm just doing a lecture, why are so many talented people here?" ”

"Hey!" Professor Yang smiled: "It's not that this matter has a big impact, you think about it, it's shocking to move the laboratory for you, so many people come to listen to it with curiosity." ”

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

But if you think about it, yes, if you hear about it, you will be curious.

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

Curiosity is a human desire to explore, so there are bound to be a lot of people who come to see it.

An hour later, the car drove into Kyoto Polytechnic University!

At this time, there were many people sitting in a classroom at Kyoto University of Technology.

These people were all over forty years old, and they were talking to each other.

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

Ten minutes later!

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

The two walked to the podium, Ye Fei was a little uncomfortable by them, there was a trace of hair in his heart, and the expression on his face was a little stiff.

Professor Yang was also a little nervous, he was not nervous to be seen by everyone, but nervous about the next test of Ye Fei.

After all, it's about whether the lab is relocated or not, and it's about the success or failure of his laser research.

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

Everyone nodded, looking at Ye Fei with a curious look.

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

Professor Yang said: "I think you have all heard about it, the principal wants to test Ye Fei's ability in Gaussian functions, and you can also help investigate it." ”

Everyone bowed slightly, agreeing with Professor Yang's statement.

Professor Yang turned his head to look at Ye Fei and asked, "Ye Fei, no problem!" ”

Ye Fei took a deep breath, spit it out again, and said, "No problem." ”

Everyone looked at Ye Fei as if they were nervous, and they all smiled.

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

"If your abilities can conquer us, I will agree to relocate the lab."

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

Ye Fei didn't offend them, and there was no conflict of interests 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 the tension in his heart was removed by most of it.

He bowed his head slightly and said, "Hello everyone, I'm Ye Fei, and I'll explain the Gaussian function ......."

"I'm going to focus on Gaussian kernel functions today."

The scene of the "Gaussian Kernel Function ......" was in an uproar instantly.

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

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

Gaussian function and normal distribution are the most widely studied, ranging from simple to difficult.

The study of Gaussian kernel functions is difficult.

If we talk about the 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 threshold for the study of Gaussian function and normal distribution is low, and the upper limit is lower than that of Gaussian kernel function.

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

Most people study theories by studying Gaussian functions and normal distributions.

Very few people study the Gaussian kernel function.

Only when the Gaussian function and normal distribution are thoroughly studied will the Gaussian kernel function be studied.

The reason why everyone is surprised is that there are very few young people around the world who study Gaussian kernel functions.

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 come up with something that you just understand to speak.

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

Professor Yang also looked at Ye Fei in amazement, he didn't expect Ye Fei to give a speech on Gaussian kernel functions.

He thought that Ye Fei would only come up with Gaussian functions and normal distributions.

But he didn't say much, he thought, Ye Fei should not be a reckless person, since he came up with the Gaussian kernel function, he naturally has a certain certainty.

Ye Feidao: "My explanation is divided into two parts, namely the separability and locality of Gaussian kernel functions. ”

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

Ye Fei found that the more he talked, the less nervous he became, and after talking for more than ten minutes, there was no tension at all, as if these experts, professors, and academicians in front of him were really his students.

"So that's ......" the dean of the School of Mathematics nodded slightly: "It's a very novel idea to introduce the Gaussian kernel function with vector machines, and select the Gaussian kernel radius kernel penalty parameter C through the VC dimensional theory and the principle of structural risk minimization." ”

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

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

Others use vector machines to learn kernel functions, but Ye Fei uses them to elicit kernel functions.

Ye Feidao: "One of the known methods is to leave an error in the upper bound of Joachims as the nuclear radius ......"

The honorary dean was surprised in his heart: "Take the upper boundary of Joachims as the nuclear radius?" What a brilliant ......."

There is an SVM mechanism inside the support vector machine.

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 originally suitable for Gaussian kernel functions, more suitable for Gaussian kernel functions.

"Wonderful...... many people said excitedly: "How could I not have thought of it!" ”

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

The principal looked around left and right, seeing that many people were very excited and shocked, he wondered in his heart: "Could it be that Ye Fei said it very well?" ”

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

The principal whispered to the dean of the School of Mathematics beside him, "Old Xu, is he speaking very well?" ”

Lao Xu shouted softly: "Don't make noise with me, listen carefully." ”

The principal looked confused, and was helpless: "Yes, wait until you finish listening and then ask!" ”

But he couldn't understand it, and it was like chewing wax.

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

"I'm done, thank you!"

After speaking, Ye Fei bowed to everyone.

"Finished?" Dean Xu was stunned, took out his mobile phone and looked at the time, and listened to it for nearly an hour.

"So fast?" He shook his head slightly, and said in his heart: "Sure enough, happy times pass quickly." ”

Then everyone stood up and burst into applause.

"Bang Bang Bang ......"

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

"Hmm!" Ye Fei bowed slightly.

The headmaster said to everyone, "Everyone, let's find a place to discuss!" ”

Everyone nodded: "Okay!" ”

With that, the people left the place.

After sitting down in the classroom next to him, the principal said, "Everyone, you also know that I don't study mathematics, let's talk about the depth of Ye Fei's explanation!" ”

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

"To be honest, I don't have that kind of knowledge at his age."

"His current knowledge is equivalent to that of me at the age of forty, and even many of his views have struck me."

The life of an average scholar is the learning stage until the age of 35, the peak stage is from the age of 40 to 50, and the decline is after the age of 50.

It's not that the knowledge is not as good as before, but the brain is not as inspired as before.

Learning needs inspiration, and so does research.

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

The headmaster was amazed that the height of this praise was too high.

He didn't think that Lao Xu was praising Ye Fei, he had worked with Lao Xu for many years, and he knew what Lao Xu's character was.

Lao Xu has a serious personality, is straight, speaks straightforwardly, and will never do anything to praise people.

Unless the person is really talented.

"Principal Lin, tell me about it." The headmaster looked at the dean emeritus.

"Dean Xu is right." President 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 Beili, there are very few people who have studied Gaussian kernel functions so deeply after graduating with a doctorate. ”

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

As a fellow of the Beili Mathematical Society, President Lin has served at both MIT and Princeton, and compared Ye Fei with MIT and Princeton students.

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

You know, MIT is known as the strongest engineering university in the world, and Princeton is met by the strongest science university in the world.

The principal was surprised, this comment was even higher than the evaluation 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 from all over the world.

The corners of the principal's mouth twitched, and he said, "Principal Lin, is the evaluation you gave a little high?" ”

The principal and Principal Lin have not been in contact for a long time, so I don't know Principal Lin's character.

Principal Lin shook his head: "No, it's not high at all." ”

Dean Xu said: "I can testify to this, Ye Fei deserves this evaluation." ”

When the principal saw Dean Xu say this, he believed it in his heart.

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

Everyone was talking nonsense, and they all highly praised Ye Fei.

After a long time, the principal said, "Everyone, you say, with Ye Fei's current ability, how much help will it be to the research of laser weapons?" ”

Dean Xu said: "Judging from Ye Fei's current ability, having him join the research of laser weapons is like a tiger with wings. ”

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

Everyone nodded, it is true, with Ye Fei's research on the Gaussian kernel function, the theory is absolutely fine.

The principal said, "That means that there is no big problem with the application?" ”

The theory is fine, and the application is certainly not a big problem.

It's basic common sense.

"Yes!" Everyone bowed their heads.

The headmaster took a deep breath, spit out slowly, and said, "I know." ”

"In other words, he joined the laser weapons research and helped a lot, didn't he?"

"Yes!" Everyone nodded.

"Okay, I got it." The principal smiled, "Thank you for coming today." ”

After some pleasantries, everyone left.

The principal found Ye Fei and the others, and Professor Yang stared at the principal tightly and asked, "How is it?" Agree to relocate your lab? ”

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

He chuckled at Ye Fei again: "Ye Fei, you follow Professor Yang to rest first." ”

"Good!" Ye Feidao.

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

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

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

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

Facing Professor Yang's inquisitive eyes, the president did not sell his words, and said, "I agree to move the laboratory." ”

Professor Yang breathed a long sigh of relief, completely let go of the heart he had lifted, and released his clenched fists.

"But ......"

Professor Yang chuckled in his heart, his heart lifted again, and his fists clenched.

"But I have a better proposal to not have to move the lab."

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

said that it was good to move the laboratory, but now it is not moving, isn't this a reversal!

"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 bother moving 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."

"Isn't that a win-win-win-win-win

Professor Yang was stunned and said, "Principal, will you agree to do this?" ”

"Originally, we had a laser laboratory, and then we built one at Zhonghu University, isn't it a waste of money?"

The principal smiled: "Actually, this laboratory was originally prepared to be established, and the above was hesitating whether to establish it at the National Defense University of Science and Technology or Zhonghu University." ”

"It just so happened that we added fuel to the fire and let the above be established in Zhonghu University."

"And if we establish it in the name of joint construction with Zhonghu University, we don't have to spend money, and we can still get a good reputation."

"And, the most critical thing is that the hot potato of laser weapon research can be thrown to Zhonghu University."

He had just obtained this news, and it happened that Ye Fei had happened, so he thought about helping Zhonghu University establish a laboratory, and then throwing the experiment of laser weapons to Zhonghu University.

"Isn't it a waste of time for you to do this today?" Professor Yang looked at the principal with a confused expression.

The president said with a smile: "We will give the task to Zhonghu University, and we will also examine the strength of Zhonghu University, which is also the meaning of the above." ”

"And my research?" Professor Yang said anxiously.

Research is not just about research, it's about research funding.

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

"The above means that the funds are set aside for other research, or lasers, which are done by the laser laboratory."

"Whew......" Professor Yang exhaled and nodded, "That's fine." ”

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

There was one more sentence he didn't say, the headmaster was really an old fox.

Almost nothing was done to get the laboratory at Nakako University, and Kyoto University of Technology not only lost the hot potato, but also gained a good reputation.

Professor Yang said in his heart, "No wonder he can be the president, and I am just a researcher. ”
