Chapter 218 The New King of Bi at Longke University
When Lin Chen started writing on the blackboard, not only Liu Zhengjie was stunned.
All the senior students in the classroom looked surprised.
"Can Lin Chen answer this question?"
"How could that be? Didn't you hear what Teacher Liu just said? He's still researching this problem himself!"
"Is this guy just showing off? I've heard so much about Lin Chen, the king of showing off in freshman year, and today I finally get to see him!"
"Everyone be quiet!"
Liu Zhengjie interrupted the whispers below and turned to look at what Lin Chen had written on the blackboard.
This is……
Gradient descent algorithm?
At this moment, Lin Chen's voice rang out: "Teacher, I think your problem can be addressed by improving the existing gradient descent algorithm."
Traditional gradient descent algorithms use a fixed step size when updating parameters…
The chalk stopped, and Lin Chen drew a thick line under the formulas he had just written.
"Therefore, I think we can try to introduce the concept of adaptive learning rate and dynamically adjust the step size according to the situation of each iteration."
For example, using the Adagrad algorithm, different learning rates can be assigned to each parameter, and the learning rate can be reduced for frequently occurring features…
Lin Chen's answer was clear, logical, and well-organized. The classroom immediately fell silent as the students listened intently, some even taking notes of the key points in their notebooks.
Liu Zhengjie was stunned for a moment, then suddenly picked up his notebook and started taking notes.
He raised this question because his thinking had reached a bottleneck, and he couldn't find a way out for a long time.
I thought I'd casually add a line during class to see if I could get any inspiration from these students.
Of course, he didn't have high hopes; he was just trying his luck.
But I didn't expect it.
I actually hit the jackpot!
"Lin Chen, I don't quite understand your algorithm improvement. What does this variable factor mean?"
Halfway through taking notes, Liu Zhengjie suddenly looked up and asked a question.
"This is a variable factor I'm introducing; its function is..."
As Lin Chen explained, he also drew a diagram in the corner of the blackboard.
"Teacher Liu, look, the purpose of this factor is to shorten the training time of the model and avoid getting stuck in local optima..."
The students below all gaped in astonishment.
They couldn't understand most of what Lin Chen said.
Many people thought Lin Chen was talking nonsense.
But judging from Liu Zhengjie's reaction now, could it be that Lin Chen has actually solved the problem?
What the hell...
This Lin Chen is a freshman who has just started university!
A freshman who just entered university is actually more capable than these senior students.
Everyone felt as if they had wasted their three years of university education.
However, compared to these third-year students, Liu Zhengjie felt a much stronger sense of bitterness.
You guys are just juniors, but I'm a PhD student!
You wasted three years of college, but what about me?
Did my four years of undergraduate studies and three years of graduate school go to waste?
Second Austrian!
"These are my preliminary answers. What do you think, Professor Liu?"
At this moment, Lin Chen also stopped explaining, put down the chalk and looked at Liu Zhengjie.
Liu Zhengjie looked at Lin Chen with a sigh.
"Lin Chen, now I understand why Professor Wang values you so much. If Professor Wang hadn't already spoken to you, I would have really talked to Professor Guo about having you come here to do research."
"Teacher, you flatter me. It was just a flash of inspiration. There's still a lot I need to learn."
Lin Chen looked humble.
The others rolled their eyes.
Pack!
That's such a damn good show-off!
He truly lives up to his reputation as the new king of cool at Long University of Science and Technology!
Liu Zhengjie chuckled: "I won't stand on ceremony with you. I originally planned to submit this question as a paper to SCI, but now that I have your ideas, my paper will be completed soon."
I'll put your name on the second book, okay?
"Hi~!"
Before Lin Chen could even reply, the others in the classroom gasped and looked at him with envy.
SCI stands for Science Citation Index, founded by the Institute for Scientific Information (ISI) in the United States.
It is a globally authoritative scientific and technological literature retrieval tool, indexing numerous high-quality academic journals.
In the field of scientific research, SCI has a significant impact. The number of papers published by researchers in SCI journals and the number of citations they receive are important indicators for measuring the level of scientific research achievements and academic influence.
Universities and research institutions around the world often assess their own strength based on the number of SCI papers published.
Therefore, being able to publish papers in SCI journals is of great significance to university students.
Even if Lin Chen's name is placed in the second work, that is, the position of the second author.
But that's an SCI paper!
How dare you, a freshman, have your name appear in an SCI paper? Even after we graduate, we might not be able to publish an SCI paper.
Sure enough, even among students from prestigious universities, there are differences in ability!
"Teacher, you flatter me. I just mentioned it casually. How could I be considered a second author?" Lin Chen said modestly.
Liu Zhengjie snorted: "Stop with the pleasantries. If I say you're a slacker, then you're a slacker! I'm not the kind of person who takes advantage of students for nothing."
"Thank you, Teacher Liu."
Lin Chen thanked him sincerely and returned to his seat.
After the experiment, he understood that this moment of inspiration, though seemingly of ordinary value, was still valuable.
But in reality, it is a prop with extraordinary effects.
Once you use it, it's as if you've been given a special inspiration buff.
For example, something that he might normally have no clue about could suddenly become a solution thanks to this inspiration buff.
Just like now, with the knowledge Lin Chen currently possesses, it would have been difficult for him to answer Liu Zhengjie's question.
However, thanks to the inspiration he had just received, he suddenly discovered the key to Liu Zhengjie's problem and came up with a solution.
This effect is something that scientists and artists alike dream of!
After all, a moment of inspiration is fleeting; once missed, it can never be regained.
However, the props for moments of inspiration are ones that Lin Chen can exchange for at any time.
Of course, this prop is only an auxiliary tool. The key to helping Lin Chen answer the question earlier was the knowledge level he had improved during this period.
Without the foundation of these knowledge levels, even inspiration is useless.
……
Shortly after finishing his lecture, Liu Zhengjie excitedly grabbed his computer and notebook and headed straight for his office.
Lin Chen's advice just now gave him confidence that he could finish his paper within a week.
However, as soon as Liu Zhengjie entered the office, he saw an unexpected figure.
"Teacher Guo? You're back?"
The figure in the office was none other than Guo Baoan, Liu Zhengjie's teacher and an academician.
Guo Baoan seemed to have some good news at that moment, with a big smile on his face.
Upon seeing Liu Zhengjie, he sized him up and then smiled, "Little Liu, what's the good news? You look so happy."
Liu Zhengjie immediately nodded and smiled, "Yes, Professor Guo, my paper is making progress!"
"Oh?"
As Liu Zhengjie's advisor, Guo Baoan naturally provided guidance on the thesis that Liu Zhengjie was currently preparing.
But he also knew that Liu Zhengjie's topic was difficult to write about, and even he himself couldn't give any good suggestions.
Guo Baoan curiously read through the notebook that Liu Zhengjie handed him.
It's solved!
After carefully reading through Liu Zhengjie's notes, he smiled and said, "Congratulations, Xiao Liu. If you keep writing along this line of thought, your paper should be fine."
Upon receiving Guo Baoan's approval, Liu Zhengjie couldn't help but laugh: "Professor Guo, you might not believe it, but the person who gave me the idea was actually a freshman!"
