Chapter 40： Multidimensional Class Algorithms (Happy New Year to everyone)

Knowing that Li Yi took the vacation because he started a business, Zhang Jie couldn't help but breathe a sigh of relief, and a smile appeared on his face.

"So that's the reason, it's a good thing! You won't have many classes this semester, so it shouldn't be difficult to ask for leave. You can take care of both, so there's no need to take a break!" Zhang Jie looked at Li Yi and said persuadingly.

"Director Zhang, then I want to take a long vacation. I won't come to class at other times. Can I wait for the exam?" Li Yi nodded happily and asked with a smile.

"This, this, do you have to take so many days off? How can you not take so many classes?" Zhang Jie frowned and looked at Li Yi dissatisfiedly. It was no different from taking a break!

Li Yi smiled slightly and explained: "Director Zhang, I understand all the courses in my senior year, and taking these courses is meaningless to me. I fell asleep in the courses last semester, and I didn't pass the exams. One? Second, the company is in a critical period of development, and I really can’t live without it, so I decided to suspend my studies. If I can’t take this long vacation, I can only suspend my studies.”

After listening to Li Yi's explanation, Zhang Jie suddenly understood.

Last semester, Li Yi was hailed as a 'sleeping god' by the class, Zhang Jie had heard a little, but he didn't get involved too much.

University life, how students study, how to plan their lives, the time arrangement depends on the students. University mainly cultivates students' ability to learn and self-discipline. Occasionally skip classes and sleep in class, such trivial matters will not be taken care of.

Li Yi's final exam results can be ranked first in the year, which is enough to prove that his excellent self-learning ability far exceeds that of other students.

In this special case, it is relatively easy to pass the application for long-term absence of classes.

Zhang Jie thought for a while, looked at Li Yi and said, "I have to discuss this with a few subject teachers. How about giving you an answer later?"

"Director Zhang, can you hurry up!" Li Yi asked with a wry smile.

The six project teams that developed the simulation system wanted to become his tail and followed him every day. Li Yi didn't spend so much time in school.

"Okay! Come with me, let's go to Teacher Keren's office to see if they are there." Zhang Jie had no choice but to respond.

Teacher Keren has a lot of classes in a day. After class, they either go to the laboratory or leave the school. They rarely stay in the office.

Only a few steps away, take Li Yi over there, can't see anyone, can let him give up.

Soon, Zhang Jie brought Li Yi to the door of a teacher's office and was stunned by the scene in front of him.

Teacher Ke Ren, who is usually invisible, sat in front of the computer, typing codes, and discussing algorithm issues from time to time. The scene was noisy, just like a vegetable market.

Among these teachers, there are several white-haired professors, and many of them are graduate students who lead subjects, and they usually lead classes.

Graduate students all have a required course called: Teaching Assistant Practice. On weekdays, professors will ask graduate students to teach low-level students. Usually, they are instructed and guided by their tutors.

Today, instead of taking classes or going to the laboratory, they gathered in the office, not knowing what they were doing.

Zhang Jie took Li Yi into the office, everyone was busy, as if no one noticed their arrival, they were all attracted by the computer screen.

"Professor Liu, what are you doing!" Zhang Jie took Li Yi to a professor who was about fifty years old and asked curiously.

"Xiaojie is here! Do you have anything to do with me? I just don't have time at the moment. I'll talk about it another day?" Hearing the voice, Professor Liu Qinghong didn't even turn his head back, focusing all his attention on the LCD screen, saying bluntly .

Zhang Jie smiled bitterly, and finally found the righteous master, but he hasn't even said anything yet! This is blocked.

Zhang Jie is just an ordinary counselor, and he doesn't even have the school's administrative structure. Like Professor Liu, who has a school's career structure and a senior professional title, he has no courage to offend him.

"Li Yi, Professor Liu and the others are not available right now, otherwise, we'll talk about it another day?" Zhang Jie looked at Li Yi and quickly persuaded him.

Hearing this, Li Yi Wanran smiled, but he wasn't annoyed. If he were an ordinary student, he would definitely back off after hearing what Zhang Jie said.

However, after this period of training, Li Yi has the experience of managing the company, giving lectures to people, and hosting meetings. Li Yi's personality and the way he treats people and things have all made great progress.

"Director Zhang, please wait a moment." Li Yi smiled at Zhang Jie, walked to Professor Liu's side, and said, "Professor, you are studying a multidimensional algorithm!"

Hearing Li Yi's words, Professor Liu Qinghong turned his head sharply, looked at him in surprise and asked, "Yes, how do you know this algorithm?"

Li Yi laughed dumbly. This algorithm was published by him in the pass-through system, and no one can understand it better than him.

"Well, after some research, learning this algorithm requires certain skills." Li Yi nodded with a smile and reminded.

Hearing this, Professor Liu Qinghong was refreshed and couldn't wait to ask, "What skills do you need?"

"Using another algorithm logic, UU reading multi-dimensional class algorithm belongs to the causal structure, and cannot be understood by ordinary algorithm logic!" Li Yi continued.

"Causal structure!" Professor Liu Qinghong was a little at a loss. At the same time, looking at Li Yi's eyes, he was full of curiosity.

The pass-through system has become popular throughout the colleges and departments. They have exhausted their strength, helped to write codes for free, and gained a lot of knowledge of new algorithms. However, only with the knowledge of these new algorithms, they have no matching learning skills. and methods, therefore, everyone learns very painfully.

Professor Liu Qinghong is not young, and it is particularly difficult to learn this new algorithm.

"Yes, a multi-layered chain-like structure. Let's put it this way, Professor, do you know anything about the polynomial regression algorithm? If you know it, I can use this popular algorithm to make an analogy and dismantle it." Li Yi looked at Professor Liu Qinghong and asked with a smile.

"Understand, have a certain understanding, polynomial regression algorithm is a supervised regression learning algorithm. The regression algorithm establishes a regression model between variables and obtains the correlation between variables and dependent variables through the learning process..." Professor Liu Qinghong nodded quickly. , introduced.

"Very well, it's much easier to talk about this way. In many cases, the linear model cannot fit the target data curve well, and a nonlinear regression model needs to be introduced. If a multi-dimensional class algorithm is used, an optimization function of a class function can be constructed, ... ." Li Yi looked at Professor Liu Qinghong, eloquently explained the main points of multi-dimensional algorithms, and the thinking logic of transitioning from ordinary algorithms to new algorithms.

Zhang Jie was stunned. Seeing Professor Liu Qinghong listening attentively, sometimes he suddenly realized, and sometimes he kept nodding his head, and the whole person was stunned.

What is this scenario!

Is Li Yi giving a lecture to Professor Liu?
