This is the first time Xu Yun went to Zhouzhi's office after graduating from undergraduate, and it didn't take long to get off the road, although it has entered July, there is basically no concept of summer vacation for graduate students.

As soon as I pushed the door in, I saw that Zhou Zhi's two doctoral students were also there.

Everyone is an old acquaintance.

No need to be polite.

After nodding to each other, he turned his gaze to Zhou Zhi, and took the initiative to speak with a smile on his face.

"Professor Zhou."

"What's the matter with you calling me over?"

He is still grateful to Zhou Zhi, who has provided help with image restoration tools and papers.

Therefore, after receiving the news, he ran over from the Institute of Advanced Mathematics without saying a word.

"It's not easy to see you now."

Zhou Zhi didn't know what he had in mind, and his emotions were a little complicated when he responded to this sentence.

Xu Yun was still smiling: "It's not a matter of sending a message for Professor Zhou to find me, and now I can be regarded as a person from the Accounting Academy." At the end, I didn't forget to remind you one more point.

When Zhou Zhi heard this, his mood was even more indescribable.

At the beginning, he took a fancy to Xu Yun's talent in the field of computer science and wanted to pull him to the Academy.

For this reason, he also deliberately went to Tang Yanshan to ask for someone.

However, in the end, it was in vain.

But later, Xu Yun completed all the major courses in mathematics in a short period of time, and successfully proved the world's mathematical problem Hodge's conjecture, which made him a little glad that he didn't succeed.

If Xu Yun was really brought to the Planning Academy, I am afraid that today's Hodge conjecture would not have been proven.

But what people really didn't expect was that Xu Yun ran back to the Institute after graduating from his bachelor's degree.

and also recognized the principal as a mentor.

At this time, Zhou Zhi shook his head, threw away the messy thoughts, and frowned.

"Alright."

"Let's sit down first."

After greeting Xu Yun, he looked at Yang Ningkun and Wang Bo next to him, and his tone obviously became stern when he called them.

"Why are you still stupid, hurry up and pour tea for your junior brother."

"Okay."

Hearing this, the two hurriedly answered, and in a panic, one went to get the cup and the other went to turn over the tea leaves collected by Zhou Zhi.

Although Xu Yun is Wu Zhongping's graduate student, he and Yang Ningkun and Wang Bo are now also considered brothers, and they did not forget to thank them when they took the tea from them.

"Thank you, brother."

Soon, Zhou Zhi stopped beating around the bush, and went straight to the point when Xu Yun put the tea to his mouth and tasted it carefully.

"Actually, I called you over today, mainly to help the two of them." Speaking of this, he immediately set his eyes on Yang Ningkun and Wang Bo: "I helped call people, and you should say the matter yourself." ”

Hearing this, Xu Yun also took the opportunity to look at the two.

Originally, he thought that Zhou Zhi had something, so he was in a hurry to come over, but he didn't expect it to be for his graduate school.

Of course, this is nothing to him, and when he published his first paper before, it was Yang Ningkun who took the initiative to help solve the negative impact of the school's post bar.

Noticing that the two of them didn't speak for a long time, he simply took the initiative to guide the topic.

"The two senior brothers need my help, although they say, as long as it is within my ability, I will definitely not sit idly by."

may have Xu Yun's words as support, Yang Ningkun and Wang Bo suddenly flashed a glimmer of light in their eyes.

In the end, I saw Yang Ningkun take a step towards Xu Yun, and his face still looked a little embarrassed when he spoke.

"That."

……

"It's such a junior brother."

"We would like to invite you to participate in our research project."

"Mainly responsible for Fourier transformations."

After he and Wang Bo were admitted to the doctoral program, they decided on the research direction of the subject after discussion, and also invited a master to participate in the research, but they still need special people to be responsible for mathematics.

They already knew and knew Xu Yun's level of mathematics from the time he first entered the school.

If Xu Yun joins the project, the research will undoubtedly get twice the result with half the effort.

However, considering Xu Yun's achievements in mathematics, especially recently being urged by the entire number theory community, it is definitely not good to invite him to devote his time and energy to their subject in this case, but surprisingly, Xu Yun studied artificial intelligence and machine learning in graduate school, which happens to be related to the topic they are studying.

In addition, Xu Yun's tutor is still the principal, so if you really join, you can ask for advice if you encounter problems.

So the two hit it off, and deliberately found their mentor Zhou Zhi as an intermediary.

That's where we are today.

However, they didn't have much hope for Xu Yun to join, so they were a little embarrassed.

After listening to Yang Ningkun's words, Xu Yun's heart moved.

Wu Zhongping's study plan for him has been completed, and the relevant books and teaching materials have been engraved into his mind, and he needs to participate in the research of the project and use it flexibly in the actual operation process.

If the content of the topic is appropriate, it is a good opportunity.

The thought stayed here, and he no longer had any hesitation, and immediately took the initiative to ask.

"Senior Brother Yang."

"I don't know what your project is heading?"

"A Medical Image Reconstruction Algorithm Based on Deep Learning." Without waiting for Yang Ningkun to answer, Wang Bo next to him couldn't help but reply.

The whole person is visibly agitated.

After all, Xu Yun is willing to ask about the direction of the subject, which means that he is still interested in it.

"Speaking of which, you're good at it, and since you want to learn artificial intelligence and machine learning, Xiao Yang's topic is a good opportunity to practice."

At this time, Zhou Zhi also took over the conversation and added, which can be regarded as analyzing the problem from Xu Yun's point of view.

And as soon as the voice in front of him fell, the back foot deliberately emphasized: "Of course, you should decide whether to participate or not." ”

Zhou Zhi's words are indeed very correct, medical image reconstruction is also a specific application of intelligent image restoration technology in his mind, which is quite suitable for his current situation.

Thinking that there is no new progress in topological group theory for the time being, it is better to diverge from thinking about a different topic.

After thinking about this, he resolutely agreed.

"I'm joining."

"It's wonderful." Wang Bo did not hide the joy in his heart when he heard this.

But the next second, I heard Xu Yun's words turn around: "But I still have one more request." ”

Compared with Wang Bo's expression frozen on his face, Yang Ningkun calmly motioned for Xu Yun to speak.

"Senior Brother Xu, please speak."

"In addition to being responsible for the Fourier transform, I will also participate in the research of your image reconstruction algorithms."

"I don't think Senior Brother will refuse this request." Xu Yun replied with a faint smile on the corner of his mouth, very humorously.

He is now a graduate student at the School of Planning, and he must not only be responsible for mathematics.

Moreover, the Fourier transformation could not be easier for him.

Although Yang Ningkun and Wang Bo are already doctoral students, Xu Yun is the big thick leg in their hearts.

At the moment, the thick thighs are asking for more content, and they are naturally too late to be happy.

After all, who doesn't want to experience the feeling of a big guy flying with a big guy.

Hardly any hesitation, Yang Ningkun suddenly stepped forward and held Xu Yun's hand tightly.

"Senior Brother Xu."

"Welcome to our group."

The matter was completely decided, it seems that he was afraid that Xu Yun would suddenly regret it.

Wang Bo saw this scene in his eyes, and his originally frozen expression returned to a bright smile.

I can't wait to go to the research room arranged by the college and have a good time doing research.

After successfully solving his own problem, Xu Yun immediately left Zhou Zhi's office and took a taxi directly to the old campus, and came to the principal's office to briefly explain the situation.

In any case, Wu Zhongping is his mentor, and he has participated in other doctoral projects, so he must inform him to avoid Wu Zhongping from arranging projects for him repeatedly. After Wu Zhongping learned of this, he was naturally very supportive, and had no objections, and promised on the spot that he could ask him for advice at any time if he encountered problems during the research process.

On the same day, Xu Yun also received information from Yang Ningkun, which was basically about their topic.

Xu Yun deliberately studied it carefully in the evening, saving time when he couldn't keep up with the current progress of their project.

When it comes to medical images, tomography is the most important component.

If you want to know the internal structure of a watermelon, the easiest way is to cut it directly.

But this approach obviously cannot be applied to patients.

As a result, there is a way to obtain information about the internal cross-section without cutting the object open.

This method is known as tomography.

And its essence is a means of data analysis.

However, due to various objective environmental constraints in the real world, it is difficult to achieve a complete reconstruction of the measured parameters.

Coupled with the fact that all continuous natural phenomena are stored and processed in a computer in an interpolated manner, this inevitably introduces non-measurement errors.

In short, it is almost impossible to perfectly reconstruct the internal image without cutting the watermelon, but many of the effects can be minimized through algorithms.

Yang Ningkun: Their task is to use deep learning to build an algorithm that can more perfectly reconstruct the internal image.

Machine learning is a subfield of artificial intelligence, and deep learning is a subfield of machine learning.

Xu Yun relies on the strength he has now to participate in this algorithm architecture, which is indeed not a difficult topic for him.

What's more, the intelligent image restoration technology in his mind has a lot of leading things to dig into.

In this way, Xu Yun roughly finished reading the information sent by Yang Ningkun that night, and he was basically sure in his heart, thinking that it would not take long to complete this project and promote the development of the domestic medical field. At that time, if you change your mind and then refine the topological group theory, you may have new ideas and inspiration.

If it still can't reach the ideal level, then you can only rely on the remaining 300 points and two energy capsules to turn on brain overclocking.

However, after all, topological group theory involves the proof of number theory problems, and even if his various abilities have been improved, there is still no absolute certainty that these integrals can be maintained until topological group theory is completely perfected.

"Participating in new research projects, I don't know if there will be a mission, and I'm really looking forward to tomorrow."

Lying on the bed, Xu Yun muttered to himself, and then stopped thinking about it and gradually fell asleep.
