Chapter 370 Professor Li's Daily Concerns
12 month 16 day.
There was snow that had not yet melted on the tree branches. The sun had come out, and it brought a hint of warmth to people's bodies. At 8 o'clock in the morning, after Xu Qingzhou and Song Yao finished their breakfast, they went to the Sutra Academy together.
In the past few days, Xu Qingzhou has perfected ARIMA and will hand in the task today.
"What a shame. After today, there don't seem to be many reasonable reasons to go to your office."
Xu Qingzhou walked with his hands in his pockets, sighing.
Song Yao squinted at him and chuckled, "You want to go study? I don't even want to point it out to you."
This guy just likes to make moves in the office.
"This is a little hobby between lovers." Xu Qingzhou said lazily.
Song Yao muttered softly: "Obviously a pervert."
Xu Qingzhou shrugged. He was already immune to the word "pervert" from Song Yao's mouth. This girl despised him for being perverted every day, but she still cooperated with him secretly.
Someone still replied in a suicidal way: "Give me your feet every day, I don't know who is the pervert."
As expected, I got hit on the waist.
The two turned at the intersection and arrived at the seminary.
"Junior Sister Song, Junior Brother Xu, good morning."
Downstairs, Han Shiyi, a food lover, was munching on a steamed bun and waving to greet the two of them.
"Morning~"
Xu Qingzhou and Song Yao responded.
Han Shiyi saw Xu Qingzhou holding his waist and was surprised: "Junior brother, what's wrong with you?"
Song Yao also turned and stared at him, the threat in her eyes was self-evident.
"It's okay, just a little itchy." Xu Qingzhou shook his head.
In the office, at 9 ., the project team members were already seated in the conference room. Li Daiyue and Ke Chen respectively explained the progress of the sections they were responsible for at the meeting.
“We have verified the periodic characteristics of the time series through tools such as spectrum analysis and autocorrelation functions.”
After Professor Ke Chen finished speaking, he looked at Xu Qingzhou and asked, "Qingzhou, how is the situation over there?"
Han Shiyi and others looked over curiously.
Li Daiyue's gaze also fell on Xu Qingzhou, and she was somewhat curious about the degree of completion of Xu Qingzhou's model.
This guy and Professor Ke guaranteed that the error would be around .
It's very difficult.
If the error is high, after all, he is Xiaoyao's boyfriend, so he should be encouraged.
but
She glanced at Song Yao beside her. Her disciple didn't seem worried at all, which meant that Xu Qingzhou's model should not be too bad.
Xu Qingzhou nodded, smiled faintly and said, "I lived up to everyone's expectations. I just finished the model yesterday. The completion degree is pretty good, and the error is within the standard range given by Professor Ke."
Han Shiyi nodded slightly. As expected of his junior brother, there was no problem at all. The others also smiled.
"How much?" Ke Chen asked with a smile.
Xu Qingzhou said in a deep voice: "If nothing unexpected happens, the error should be around ."
"Yeah," Professor Ke Chen nodded, but soon found something wrong. He paused, looked at Xu Qingzhou, and raised his voice a few decibels, "What do you think the error is?"
“About .”
Xu Qingzhou spread his hands and said helplessly: "It's still a little high. I was planning to lower it, but time is limited. I can only make do with it. It can meet your computing needs for now."
"Junior brother, are you sure it's , not "
After a brief silence in the conference room, Han Shiyi swallowed and wanted to confirm it again.
The model produced by the top team in the United States has an error of . "Yes." Xu Qingzhou nodded affirmatively.
"."
.
Will you still use it?
Ke Chen's mouth twitched.
In front, Li Daiyue also looked at Xu Qingzhou deeply. She suspected that this boy did it on purpose.
I have to admit that Xu Qingzhou is a genius.
To a certain extent, the impact that Xu Qingzhou brought to Li Daiyue this time was greater than the previous times when he solved some conjectures, because that was an unfamiliar field for her.
A single person can reduce the error to , which is completely equivalent to a top team.
Xiaoyao
Li Daiyue's focus now is on Song Yao beside her, and worry arises in her heart again.
If the boy is too strong, the balance between the two people can easily become unbalanced.
In the end, the one who suffers the most is definitely his own apprentice.
On the side, Song Yao rested her chin on her hand and sighed inwardly, "This guy is so mean. He could have said it directly, but he insisted on keeping it a secret."
Xu Qingzhou handed in the model, and on the 18th he worked together to solve two more calculations. The work at the School of Economics came to an end, and he could devote all his time to the study of local smoothness.
library.
Xu Qingzhou was looking at the manuscript paper full of equations, thinking about how to verify the inequality he encountered. "So, here, the key to proving this inequality is to establish a discrete bilinear square function estimate."
"In a sufficiently small spatial scale, the oscillatory integral is approximated by the extension operator V, assuming that δ> 0 and 1≤K≤λ, and Taylor expansion is performed near point z, followed by variable substitution."
After a short pause, my mind was open again. After using the third method, the calculation went smoothly.
On the afternoon of the 21st, Xu Qingzhou found a tool that could transform or cut the puzzle at will, and the "bilinear equivalent form" had formed a complete figure.
Song Yao has been even busier than Xu Qingzhou these days. In addition to working on the project with Li Daiyue, she also has a very important job - preparing her graduation thesis.
According to previous plans, she needs to complete enough undergraduate credits one year in advance and graduate in June next year.
On the 23rd, at 5 pm, Xu Qingzhou took a taxi to the Wanhe Hotel next to Xiangshan Mountain.
"Junior brother." Gong Yunfei waved his hand. "The professor and his friends just went in. Hehe, they've been waiting for you."
"Where are you going to play next?"
Xu Qingzhou asked with a smile.
"I'm not heading north this time. I plan to go to Sanya."
"Good."
Two and a half years have passed, and everyone in the original research group is still there. Senior Brother Gong is now in his first year of doctoral studies, and Hong Yayu and Wang Wei have both graduated with their doctorates. I just don’t know whether they will continue to stay in the research group after this project is completed.
Xu Qingzhou and Gong Yunfei walked in together, to the private room where they had dinner last time.
"Okay, everyone is here." Zhao Shengwen motioned Xu Qingzhou and Gong Yunfei to sit down and asked the waiter to serve the dishes. At the same time, he said with a smile:
"Okay, as usual, I'll just say a few words. It's been almost two years since February last year, and I have to thank everyone for their hard work and efforts over the past two years."
"Of course, the most important thing is the project bonus, which will be deposited into everyone's account tomorrow."
"Thank you Professor!"
"The professor is awesome!"
Wang Wei and Gong Yunfei were applauding beside them. Hong Yayu still had that cold look on her face, but judging from her relaxed brows, she was in a good mood.
Xu Qingzhou also smiled and applauded. Zhao Shengwen was very generous.
He agreed with Professor Zhao's point. As a mentor and the head of a research group, he certainly could not rely solely on ideals and beliefs to encourage his team members.
