Chapter 125 He is the God of Our Academy
Yao Qizhi was a little surprised by Xu Yuan's answer. In his opinion, Xu Yuan could have such advanced thinking about machine learning algorithms, and he should have done some research before. Just as he was about to continue asking questions, he was interrupted by a sudden shout.

“The algorithm performance evaluation is out.”

Guo Zhihang shouted to everyone excitedly, his eyes fixed on the screen.

The performance evaluation of the algorithm includes multiple indicators such as accuracy, precision, recall rate, and confusion matrix curve value. At this moment, under the operation of Guo Zhihang and Zhu Minfeng, the data of various indicators have been presented, and the performance of this algorithm can be judged intuitively.

In particular, there are previous algorithms for comparison.

Zhu Minfeng was the first to say, "The performance of the new algorithm has improved several times." His face was full of surprise and astonishment.

He knew that Xu Yuan had adopted a different modeling approach from their previous ones, but because it was completed so quickly, he subconsciously did not hold out much hope.

But after dozens or hundreds of verifications and evaluations, the data obtained slapped him in the face.

The performance of the new algorithm is completely unmatched by their previous algorithms. It can be said that the two are completely not on the same level and are not even qualified for comparison.

"The accuracy rate is really high. If it is applied to image processing, the role it can play will be immeasurable." Guo Zhihang took over Zhu Minfeng's words and added, his eyes wider than ever.

The other two graduate students were equally excited, with smiles on their faces.

"The problem that our team has been working on for so long but has not been solved is so easy for Xu Shen."

"God Xu is really amazing."

While sharing their inner feelings with each other, their gazes involuntarily moved to Xu Yuan, their eyes full of admiration and worship.

Their machine learning algorithm project is applying for national funds. Now with the help of Xu Yuan, the algorithm performance has been improved so much that it may become a national key support project after being reported. The benefits of being a main member of such a project are self-evident.

At this time, Yao Qizhi leaned over and saw the evaluation results on the screen. He was so excited that he didn't even care about his image.

"it is good."

"Great."

"Okay!"

He clapped his hands on the table and said "OK" three times before he was willing to straighten his body.

Then he grabbed Xu Yuan's arm and said, "My judgment was correct. You used the optimal transmission framework instead of the neural network to build the algorithm model. This new idea has enabled us to take our research on machine learning a step further." His emotions remained high throughout the whole process.

This is enough to show the value of this algorithm.

"It turns out that Junior Brother Xu is so good at constructing mathematical models. I was worried at the beginning that he wouldn't be able to do it." Guo Zhihang felt a little embarrassed when he heard this.

Zhu Minfeng on the opposite side quickly took over the conversation and said, "It's because our understanding is not yet at the level of Junior Brother Xu."

Xu Yuan felt the strength coming from his arm. Facing the self-deprecating words of his two senior brothers, he quickly waved his hands and said, "It just so happens that I have studied the optimal transmission theory a lot, so I quickly determined the idea."

It can be considered as giving face to Guo Zhihang and Zhu Minfeng.

However, Yao Qizhi only had his eyes on Xu Yuan, and the next second he criticized the two of them without any hesitation.

"Xu Yuan, you don't need to speak for them. The two of them with PhDs are not as good as you, a math student, in the field of algorithms. This project has exposed many problems."

Guo Zhihang and Zhu Minfeng listened obediently to Yao Qizhi's scolding. Although they felt uncomfortable, they couldn't find any reasons to refute.

As for the other two graduate students, they remained silent and dared not say a word.

I was afraid that I would be affected too.

And Yao Qizhi's next sentence was even more shocking.

"You know what, Xu Yuan? I want to recruit you from the Department of Mathematics. If you come to the School of Computer Science to continue your research in the computer field, I can guarantee that your achievements will definitely win the Turing Award."

"How about it?"

"Would you like to think about it?"

For the four people present, including Guo Zhihang, everyone knew what the Turing Award represented.

As the highest international award in the computer field, it can be regarded as the Nobel Prize in the computer industry, and its status is similar to the Fields Medal in mathematics.

Although they are all studying for graduate degrees and doctorates, they dare not even think about winning the Turing Award.

But now they heard something.

Professor Yao actually said that Xu Yuan would definitely win the Turing Award.

That's right.

It is definitely award-winning.

Just from this sentence, we can see that Professor Yao values ​​and has high expectations for Xu Yuan.

I originally thought that Xu Yuan was talented enough as he published a paper in the Annals of Mathematics and was honored as the Prince of Mathematics, but it turns out that the same is true in the field of computer science. He really leaves no room for ordinary people to survive.

Xu Yuan was a little stunned when he heard what Yao Qizhi said. He didn't expect that he just came to help a little, but he saw the person was about to be kidnapped.

He paused for a moment to come back to his senses before answering: "Thank you Professor Yao for your affirmation of me, but my current focus is still on mathematics. Besides, studying mathematics does not affect my exposure to other technical knowledge. If the School of Computer Science needs help in the future, you can always come to me." At the end, he did not forget to add a special sentence.

"never mind."

"If I really kidnap you here, all the old professors in the mathematics department will come after me and kill me." Upon hearing this, Yao Qizhi smiled and changed the subject.

The idea just popped into his mind because he was excited, but now he thinks it is unlikely.

In addition, as Xu Yuan said, studying mathematics does not affect development in other fields, and this machine learning algorithm is the best proof. After all, if it were not for Xu Yuan's research on optimal transmission theory, it would be impossible to improve the algorithm performance so much in a short period of time, and even directly promote the progress of machine learning algorithms.

Even though today's events had progressed to this point, Yao Qizhi did not forget about the main business.

Then he turned around and said to Guo Zhihang and Zhu Minfeng, "You should complete the detailed papers and submit them as soon as possible. There is a great hope that you will be able to obtain support from the National Fund this time." His eyes were shining as he spoke.

Judging from his experience, the performance of Xu Yuan's machine learning algorithm is probably already at the leading level.

Whether it is applied in image processing or speech recognition, it can play a very important role, especially with the improvement of hardware performance with the development of industry...

"Don't worry, Professor Yao."

"We have been working overtime these days to finish the application papers." Guo Zhihang and Zhu Minfeng answered with high morale.

Then Yao Qizhi seemed to suddenly think of something.

I reminded you again.

"One more thing."

"Is it okay for you to add Xu Yuan as the first author?"

As soon as he finished speaking, Guo Zhihang and Zhu Minfeng rushed to express their attitudes.

"Definitely."

"The entire algorithm model was completed by Junior Brother Xu. It is only natural for him to be the first author of the project. We would have done the same even if you hadn't said so."

Under normal circumstances, Xu Yuan was asked to help, and being the second author on the project paper was already considered good, but now he directly became the first author.

After hearing this, Xu Yuan was about to say something humble, but was interrupted by Guo Zhihang.

"I'm just here to help..."

"Junior Brother Xu, please don't refuse. Without you, our algorithm performance alone would have made it impossible for the application to be approved."

Even Zhu Minfeng beside him nodded and agreed: "Junior Brother Xu, this is what you should do."

"We may need your help in the future application of this project, so just rest assured and put your name on it." Yao Qizhi said this to Xu Yuan with a smile on his face.

"OK then."

Having said that, Xu Yuan naturally had to accept it.

I thought that after mathematics and cryptography, I finally had a paper in the field of computer science.

Since he had become a core member of this project, it would be difficult for him to just leave. So he took the initiative to help complete the application paper and optimized some of the algorithm's program codes.

So much so that when Guo Zhihang and Zhu Minfeng saw Xu Yuan's ten fingers flying on the keyboard and quickly typing code to optimize the program, their jaws almost dropped to the ground.

The shock on his face was even greater than when he saw the algorithm evaluation results.

They never expected that Xu Yuan's computer skills were no worse than theirs.

Especially when I thought about what Xu Yuan said before, that he had some knowledge of computer language, I couldn't help but want to complain.

I thought, can this be called a basic understanding?

Fortunately, this scene was not seen by Yao Qizhi, otherwise he would definitely think that Xu Yuan had studied computer knowledge and his desire to poach him would be even stronger.

But the biggest advantage was that with Xu Yuan joining us, it didn’t take long to complete the thesis.

Among them, Xu Yuan, Guo Zhihang and Zhu Minfeng are the first authors, and the other two graduate students are the second authors.

……

For Xu Yuan, helping with the School of Design project was just a small episode during the summer vacation. The main purpose was to get in touch with different content so that he could think divergently and come up with inspiration so that he could continue to try to prove Qiu Chengtong's conjecture.

It turns out that his method does have a significant effect.

As the summer vacation gradually drew to a close, his ideas for proving this conjecture gradually became clearer, and he was close to finding the right direction.

Thursday, July 2004, 8, School of Mathematics, Qinghua University.

At noon, Xu Yuan accompanied Chen Yuran out of the library. After separating from each other, he walked towards the dormitory alone, still thinking about mathematical branches such as differential geometry and algebraic geometry.

I want to find a way to combine these branching methods.

It is the start of a new school year and young students carrying luggage can be seen everywhere on the campus roads.

Some were accompanied by senior students who were in charge of welcoming new students.

But Xu Yuan seemed oblivious to these youthful and beautiful scenes, and just kept muttering his mathematical formulas to himself.

"Can we try to combine these two formulas? It seems that we can get a second-order derivative formula... If we use it to verify the calculation... it should work."

Suddenly, an idea flashed upon him and he noticed that after combining the two formulas that had been lingering in his mind, the resulting second-order derivative formula might be used to prove the conjecture. After he came to his senses, he immediately ran to the nearby dormitory as fast as he could.

The freshmen who had just reported in nearby were all surprised to see this scene.

"What happened?"

As soon as he finished speaking, he heard the advice from the senior student next to him: "It's not good if you don't know Senior Xu Yuan yet. He is the real academic god of our School of Mathematics." As he said this, he looked at Xu Yuan's back with admiration on his face.
