I am devoted to scientific research, but you want to trick me into having a love relationship?

Chapter 477 Xu Qingzhou: You slandered someone's innocence out of thin air

Outside the window, night has completely fallen, the city lights are all on, and looking into the distance, various neon lights are intertwined, showing the prosperity of the modern city.

Song Yao put down her pen, walked over in slippers, and put her feet in Xu Qingzhou's arms, "What don't you understand?"

"Sparse prior distribution, use up Laplace prior, but how to reduce parameter dimension."

Xu Qingzhou slid his fingertips across the graceful calves. He had been busy during this period and had no time to touch these long legs properly.

"You asked that question last time."

Song Yao reminded.

It's confirmed. This person is taking advantage of others under the pretext of studying.

"Have you asked? Alas, I am old and my memory is not good. Let me ask you one by one, about the construction of the factor library and how to extract independent impact factors."

Xu Qingzhou remained calm.

Song Yao thought for a moment and said, "First, we need to perform Z-score standardization on the original factors to eliminate dimensional differences, and then calculate the covariance matrix."

The establishment of a factor library is an important part of the development of quantitative models in hedge fund quantification, so it seems that this guy had long seen that she would choose to continue studying the issues of hedge fund quantification.

Xu Qingzhou listened, nodding from time to time, with half of his attention on Song Yao's explanation and the other half on his legs.

Slender and round.

Full of resilience.

You can do the splits easily.

Her skin was white, delicate and tender, and even the slightest force from his fingers would leave a red mark.

very nice.

“In the third part, we need to test whether there is a lead-lag relationship between the principal components and eliminate those with a causal relationship.”

Song Yao's voice stopped abruptly. She found that Xu Qingzhou had been staring at her legs and swallowing.

This reminded her of some of the perverted things this guy had done in the past.

There was a hint of nervousness on School Beauty Song's face.

Xu Qingzhou only noticed now that Song Yao had stopped talking, and raised his head: "Go on."

Song Yao's feet moved restlessly, and her lips moved, saying, "If you dare to kiss me, I will kick you down."

"Song Yao, you slandered someone's innocence out of thin air!"

"You last time"

"Last time it was an accident!"

Xu Qingzhou's expression froze for a moment, but he quickly regained his composure and said righteously, "I'm not a pervert. Why do I keep kissing your feet? Uh, um, what were you talking about just now?"

Song Yao pouted, obviously wanting to kiss.

"Eliminate factors that have a causal relationship. For example, if the "value factor" Granger causes the "quality factor", then combine the two. You can't just do it lightly!"

"okay."

While the two young men were fishing for each other in the apartment, the MIT forum became lively because of a recruitment information posted by Xu Qingzhou.

In a student apartment next to the Charles River.

Dave Rossiter was browsing aimlessly on Handshak, MIT's official recruitment platform.

Two months after graduating from my PhD program, I still haven’t found a suitable research group.

"and many more."

Rost suddenly froze, his eyes fixed on the screen.

Xu Qingzhou!
Rost's breathing quickened as he looked at the name. As a double winner of the Fields Medal and the Wolf Prize, everyone in the mathematics community must know him.

But when these big guys form a team, they usually invite people directly in the circle and will not recruit publicly on this kind of platform. Therefore, he suspected that his eyes were playing tricks on him.

"It's really him!"

Rost suppressed his excitement and didn't dare to waste time, and quickly read the requirements. The quota for this kind of big boss's research group is definitely super popular, and the sooner you finish reading and submit your resume, the sooner you will have a chance. However, when he read the first sentence, he was stunned again.

"What the hell?"

[Recruitment positions.]

Postdoctoral researcher.

Research direction: 1. Mathematical-experimental synergistic optimization of superconducting film growth. 2. Thin film defect topology analysis and cross-scale performance prediction.

Dave Rossiter's original enthusiasm was poured with a bucket of cold water.

Condensed matter?
Not just condensed matter, but also materials science
Isn’t Xu Qingzhou a professor of mathematics? Why did he go to study condensed matter?

With doubts, Dave Rossiter went to the official website of MIT for project announcements and quickly found the project notification that was announced yesterday.

"Is this brother crazy?"

It was not even a school-level project, and the school only provided equipment, while Xu Qingzhou personally bore all the expenses of the project, which meant that there was no subsidy or funding from the school.
In terms of job requirements, Xu Qingzhou is relatively broad, including applied mathematics, materials science, condensed matter or related fields.

Salary and benefits.

Basic annual salary is 65000.

The rest of the income comes from project bonuses, but in the eyes of others, this is just a naked pie.

MIT OpenCourseWare (OCW) discussion forum.

This is one of the largest discussion forums at MIT. 80% of students find study groups through the OCW forum and share information about major projects.

"Hi, Xu Qingzhou is preparing to work on a new project."

“Are all genius ideas so different?”

"Damn it, I've already rejected two project invitations. I waited for half a month just to see if I could join Xu Qingzhou's research group. But why is it condensed matter?"

"If anyone participates in this project, they must be desperate."

"Identification completed: Big Pit Project."

"James' team in the Department of Physics is also working on this project. Compared to this, Xu Qingzhou's project has almost no chance of producing results."

"The MIT Investment Club has new material. If nothing unexpected happens, this project will definitely be on the list at the annual simulated investment conference."

The MIT Investment Club holds a simulated investment meeting at the end of the year to vote for the "least reliable" project.

"Why didn't he choose mathematics, which he was best at!"

"Yes, if it were mathematics, his project would definitely be one of the most sought-after projects at MIT."

“Has victory gone to your head just after you won the Fields Medal?”

Xu Qingzhou's recruitment notice shocked everyone, but he became famous at MIT.

Even though it has a bad reputation.

Many people were very interested in Xu Qingzhou's research, especially after he proved the Riemann hypothesis and won the Fields Medal. However, after seeing the project, they were greatly disappointed.

Xu Qingzhou didn't care about the criticism in the forum. There are thousands of people in MIT, and there will always be one or two who are blind and wrong. They must be people with vision.

The worst case scenario is that we can’t recruit anyone.

If it really comes to this, the worst that can happen is that you push yourself up or change projects.

The next morning, he went directly to the library.

The recruitment information has been sent out, but the next step is still complicated.

Project establishment and technical route design.

Technical path: mathematical modeling (phase field simulation/stochastic dynamics) → intermediate layer material screening (first principles calculation) → experimental process development (MBE/sputtering) → in situ characterization (STM/XPS) → performance verification (microwave resonance test).

In addition to establishing theoretical models and simulation verification, it is also necessary to build an experimental system.

The content that needs to be sorted out is still quite complicated.
