Chapter 292: Have to find a way to hurry

Biquge EbookFREE.me, the fastest update of the latest chapters of the learning magic cultivation system!
In the LSSVM algorithm, if you hear the word "algorithm", you can basically determine its origin in the field of machine learning.
In this field, although all kinds of algorithms are enchanting, there are thousands of styles.
However, machine learning will eventually have to implement the word "learning".
Once implemented here, it must be within Li Zheng's range.
In fact, even the basic principles are no different from those studied by Li Zheng.
Li Zheng used his brain to do a lot of papers, and then perfected his knowledge to achieve a score of 730+ no matter what kind of college entrance exams he did.
This is a complete study of Li Zheng, whose purpose is to pass the college entrance examination and rank above Lin Yuejing.
The machine uses a mathematical model to speculate on many rocket launch data, and then improves the calculation method to achieve no matter what rocket parameters are obtained, the fault can be speculated and diagnosed, and the accuracy rate is higher than 95%.
This is a complete machine learning, the purpose of which is to find the point of failure and ensure the success rate of the rocket launch.
But even if the principle is so simple, machine learning is still a deep field.
No way, the difficulty is all in the algorithm.
Take Li Zheng's study as an example.
Without considering the learning magic bonus, its efficiency and results depend on Li Zheng's IQ and learning method, referred to as learning method.
Then, at the same time, put Li Zheng, Lin Yuejing and Liu Xin together to study.
The result must be very different.
On the one hand, everyone's IQ is different, and Liu Xin may have learned it better than not.
On the other hand, everyone's methods are also different. No matter what knowledge they face, Lin Yuejing, a man who steals and plays tricks, can certainly come up with a dirty way of learning.
So under normal circumstances, the final score of the three will be-
Lin Yujing ≥Li Zheng>>>>>......>>>>>Liu Xin .
In this process, IQ is equivalent to the computing power of the machine, and the learning method is equivalent to the algorithm.
For such things as CPU computing power, there are dedicated people who are busy, as long as they shout "AMD, YES!", the CPU will instantly become stronger.
The rest of the highlights are all concentrated on the algorithm.
LSSVM is only one of the more popular ones. In addition to the traditional voice and image recognition fields, it is also gradually used in fault detection in nuclear power plants, petrochemical industry, system control and other fields.
But in the aerospace system, for the time being, traditional models and expert systems are still dominant.
Within the system, there are naturally research institutes in this direction.
The problem is that Huang Er has passed their test.
This shows that their algorithm did not detect the existing fault.
This is of course not to say that their algorithm is Liu Xin's algorithm, no matter how bad it is, it has to be...about the same level as Qi Yingnan.
Since there is a chance in front of us, we might as well try to use Lin Yujing's dirty brain.
"The plan is like this, but the ready-made LSSVM toolkit may not be too good to use directly, and some optimizations are needed for the rocket data, so I found the PSO particle swarm optimization." Li Zheng put down the tableware and said calmly. "You know, I have to understand all the principles for anything. The mathematical problems of the algorithm itself are a bit difficult to chew."
"Wait, I will ask you Mr. Shen." Lin Yujing picked up his phone and fiddled with it. After waiting for half a minute, he turned and smiled at Li Zheng. "Sure enough, the eleven schools you mentioned have been Some people have done it, they have about four or five algorithms, it should include this and what SM."
"..." Li Zheng shuddered.
"Well..." Lin Yuejing covered his mouth in contempt, "It's like you, as if you have discovered something terrible, like a civil subject."
"Regardless of whether the civil sciences or the civil sciences are used first, which algorithms did they use? How to optimize them?"
"Who knows this?" Lin Yuejing rushed to the computer room. "Anyway, the data analysis system we are using now is also made by them."
"But... since this..." Li Zheng rubbed his head. "They just changed a few parameters and tried it a few times."
"They're doing it, who said they didn't?"
"Then what does our test team do here?"
"Yeah~" Lin Yuejing groaned, "So I didn't do anything. I looked at the rocket chart by myself, so take this as a computer room where you can access the intranet database."
"You too, this too..." Li Zheng wanted to say something negative.
But if you think about it, as someone who hasn't even been able to do anything, it is already the most active way to learn knowledge as soon as possible.
On the contrary, it was myself, as if he had hit the chicken blood.
"Then I will learn for a few more days." Li Zheng wiped the rice off the table into the dinner plate. "It's only after I've done it that I know that every small thing has a dedicated team devoting huge energy to do it. It’s too deep, and one’s energy is too little.

"Oh, didn't you say you want to exercise cooperation?" Lin Yuejing also sorted out the desktop and said, "As soon as you do it, do you build a car behind closed doors like learning?"
"Did you just invite you to cooperate?"
"I'm a ball, I'm still looking at the rocket picture." Lin Yujing said and took out his phone to show it to Li Zheng. "Your teacher Shen encouraged you to study. This is the connection of the eleven technicians. Way, she just greeted you just now."
"Oh?" Li Zheng glared. "Does your mother think this optimization algorithm?"
"Your mother just thought!" Lin Yuejing said to the table, "Mr. Shen, call Mr. Shen!"
"Yes, let's call it a teacher in the unit."
"Okay, you have to remember." Lin Yujing lifted the plate and said, "I have time to look at the popular algorithm in the afternoon, just look at it casually, not too seriously."
"That's how good it is." Li Zheng got up and raised her eyes. "While taking a lunch break, go out and relax?"
"No, I'm going back to the computer room to sleep."
"That's all right, I went five kilometers by myself."
The two handed over the dinner plate.
Seeing that they are going to part ways, one when going to the computer room and the other to the yard.
Lin Yuejing suddenly felt the three anxious eyes cast behind him.
They are three major engineers, and they have finished eating, looking at this with hostility.
After they finished, they still made them angry.
If I go back to the computer room to sleep now... I'm afraid I'm even more angry?
Lin Yuejing shivered, chasing Li Zheng and ran out: "Wait for me..."
Behind them, the three engineers became more lonely.
For a few minutes, I don’t want to be in a room...
Life is often like this, even if the female high school student is born in heaven, it will not be related to you.
Instead, it will fall to a deeper valley because of being rejected.
The three couldn't help but look at each other.
Female high school students or something, does not exist.
Only we can be with each other for a long time.
"Would you like to take a step..."
"Let's go, it's been a long time since I ate."
"Wait... I always feel more stimulated..."
"In this way...hey... there is no place for shelter. Director Chen really wants to kill us."
"No, there is still a place." The high-volume engineer stared at the other two, raising his hands angrily, "King Canyon!"
"Also... only there...
"Go, go back to the cafeteria and fight..."
So, there are reasons why there are so many people in Kings Canyon.
...
At 1:30 in the afternoon, Li Zheng found the software engineer of the eleventh institute in accordance with the contact information given by Shen Tinglan.
Because Teacher Shen has already greeted him and has a very good attitude towards the opposite, Li Zheng originally spoke about the current situation of artificial intelligence fault diagnosis.
After all, this is a new field that changes every day.
And the strongest person in this field must be going to an IT enterprise, and it is not enough for the aerospace to pick.
Therefore, the main way to carry out work here is to cooperate with the laboratory of the university.
Although the software for fault diagnosis was developed by Eleven, the core algorithm is mainly developed and improved by two university laboratories. They have regular exchange feedback for optimization.
In response to Huang Er's situation, they have made several optimization adjustments, but still have not obtained a clear result, and related diagnostic materials have also been sent to the technical team.
In the end, he also sent relevant algorithm data and analysis data to He Zhongrui's internal mailbox, welcome Li Zheng for reference and suggestions.
Li Zheng thanked again and again before hanging up.
It now appears that this road does not necessarily work.
But fortunately, there is something to learn.
At this time, Lin Yuejing also had a general understanding of several mainstream algorithms.
Lied immediately.
"Impossible... give me half a year or so..." Lin Yuejing sighed with his head resting on the back of the chair. "It's not so difficult to understand the principle, but optimizing this kind of thing requires a lot of experimentation and accumulation. ...This is what the lab does... hate computers, hate programmers..."
"What if it's only responsible for optimization?" Li Zheng asked.
"Optimization also needs to be tried repeatedly, and it can't be achieved with just one shot of the head." Lin Yuejing said, "Many times, various parameters and details have to be repeatedly adjusted and combined, and a lot of results can be accumulated to find a temporary optimal direction. "
Li Zhengding thought for a while and said, "Then take a step back, do you only provide optimization ideas?"
"What's the use?" Lin Yuejing opened his arms like a monster, "Ah", "I tell you, go to nuclear fusion, you can do it?"
"No, it's a step back 10,000..." Li Zheng still explained seriously. "You must at least tell me the fuel and realization method of nuclear fusion. I'll find materials to fight the structure."
"Okay, the raw material is deuterium, the method is inertial constraint, you go and do it."
"Okay... Li Zheng sighed and returned his attention to the screen in front of him, "Forget it... I'll do it with the elder brother of the Eleventh Institute, and you will clear the mines. "
"..." Lin Yuejing was sullen, but didn't know what to say. He had to open an oversized minesweeper and started to go blind.
After a few clicks, how to die and how to die, she turned off minesweepingly again, opened the rocket structure and began to appreciate.
The annoying thing is that this rocket is not fragrant after much reading.
The more angry you get, the more angry you think.
After a few minutes of sulking himself, Lin Yuejing couldn't hold back and stepped on Li Zheng.
"Ok?"
Lin Yujing turned around and struggled for a while before saying: "...the informant was given by my mother, you don't take me!"
"Aren't you not involved yourself?" Li Zheng asked, scratching his head.
"When did I say not to participate?"
"Did you mean not to participate..." Li Zheng smiled lightly, "I understand that for this kind of hard to have any results, but also to make tremendous efforts to learn things you don't like knowledge, you can't bear it Forget it, mine clearance, very good."
"This..." Lin Yuejing struggled with both hands scratching the table. "Algorithm...I don't like chemistry. I don't like it...the algorithm is also used in astronomy deduction..."
Li Zheng didn't dare to ask too expectantly: "That's... participated?"
"I did not say."
"That's not involved?"
"I did not say!"
After a moment of confusion, Li Zheng finally understood.
"I see, you want me to beg you to participate."
"I didn't say~"
"Oh, then forget it." Li Zheng smiled and waved his hand, "Go mine-clearing, don't disturb me to study."
"!!" Lin Yuejing stomped again. "If you don't take me, I will let my mother tell the eleventh school not to care about you!"
"?????" Li Zheng's eyes glared, "Isn't it good to not touch your mother's light?"
"Your mother's light!"
"It's Mr. Shen's light... I'm not allowed to say that."
"I did not say!"
"You are boring..." Li Zheng tangled. "Not only disturbs me to study, but also prevents me from working."
"It's so powerful." Lin Yuejing waved his fist. "Do you want to bring it?"
"Just go, take it, take it, do it together."
"Add a word please!"
"Please do it together..."
"Add a word!"
"I beg you to do it together."
"Oh, there's no way." Lin Yuejing smiled, covering his face, "Zhang Yun is so pitiful, I will help~"
"Damn." Li Zheng beat the table. "The status obtained by this method is hypocritical. This status is not yours, it's yours."
"Curse again!"
As he was saying, He Zhongrui finished his rest, washed his face and entered the machine room, regardless of the three, went straight to Li Zheng.
"How? Did you do it well?"
"It has been completed and saved to the designated location." Li Zheng nodded and said, "In addition, I asked the eleven teachers to ask for some learning materials, which were sent to your intranet mailbox. Teacher He He worked hard to help."
"Eleven schools? They are mainly engaged in software..." He Zhongrui said after thinking for a while, "Oh, Zhou Chenglong has contacted you?"
"What?"
"Hi, I said to the director that you have a good foundation and learn fast." He Zhongrui patted Li Zheng with a smile, "Congratulations, you should go to the technical team soon."
"Ah?" Li Zheng froze.
"Ah?" Lin Yuejing was anxious.
Although that was Li Zheng's target team, it always felt strange to throw Lin Yuejing here alone.
Lin Yuejing is unable to accept the fact that Li Zheng is now transferred to the target team.
As for He Zhongrui, he only saw a pair of men and women who could not bear to separate.
"You... are you..." He Zhongrui swallowed and said, "Li Zheng, don't you want to leave?"
"I want to finish some more work..." Li Zheng scratched his head, "Can I leave next week?"
He Zhongrui glanced at Lin Yuejing again.
She also looked down with her head unwilling and reluctant.
Damn you.
Isn't it just classmate friendship?
How can I not let you two sleep in a bed!
Under the strong sensory stimulation, He Zhongrui swallowed a bit of sour water.
"Then... I'll talk to Zhou Chenglong again... Let you report later..." He Zhongrui said sideways, "The tasks entrusted to you can be divided."
"That must be."
"You are Xiaolin..." He Zhongruiqiang turned his head forward, "I heard that you want to go to the design team, if you don't want to spend it here, you will take the initiative to ask for some information, and learn more after work, almost at the same time. I also mentioned to them..."
"Thank you Teacher He..."
"It's done." He Zhongrui waved his arms in pain, "Go work."
One thing, he was wrong.
Pure female high school students, that really has the effect of promoting work.
But if it appears with the object.
It was a disaster for everyone.
Looking back at the three colleagues, He Zhongrui read the same insight from their eyes.
Now the situation has changed, it is no longer how to keep Lin Yuejing.
For the safety of the brethren's lives, we must quickly find a way to escape her!
