Chapter 293

In LSSVM algorithm, when you hear the word "algorithm", it can be determined that it originated from the field of machine learning.

In this field, although various algorithms are charming and colorful.

However, machine learning should be implemented in the end.

As long as it is implemented here, it must be within the range of Li Zheng.

In fact, even its basic principles are similar to Li Zheng's study.

Li Zheng, he started his mind, made many papers, and then improved his knowledge points to get 730+ scores no matter what kind of college entrance examination paper he did.

This is a complete study of Li Zheng, whose purpose is to pass the college entrance examination and rank on Lin yuejing.

The machine, using some mathematical model, speculates a lot of rocket launch data, and then improves the calculation method to achieve no matter what rocket parameters are obtained, the fault can be inferred and diagnosed, and the accuracy rate is higher than 95%.

This is a complete machine learning, the purpose of which is to find out the failure point and ensure the success rate of 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.

Also take Li Zheng study as an example.

Without considering the addition of learning magic, its efficiency and results depend on Li Zheng's IQ and learning method, which is called learning method.

Then, in the same time, Li Zheng, Lin yuejing and Liu Xin will be together to learn.

The result must be different.

On the one hand, everyone has different IQ, Liu Xin may have learned it better than not.

On the other hand, everyone has different methods. Lin yuejing, a kind of sneaky person, can come up with dirty learning methods no matter what knowledge he faces.

Therefore, in general, the final results of the three will be -

Lin yuejing ≥ Lizheng Liu Xin.

In this process, IQ is equivalent to the computing ability of the machine, and learning method is equivalent to algorithm.

And CPU computing power, there are special people to busy, just shout "AMD, yes!" The CPU will become stronger in a moment.

The rest of the play, too, is focused on algorithms.

LSSVM is only one of the popular ones. Besides the traditional speech and image recognition, LSSVM has been applied in the fault detection of nuclear power plant, petrochemical industry, system control and other fields.

But in space system, the traditional mode and expert system are still the main ones.

Within the system, there are naturally institutes studying this direction.

The problem is that Huang Er has passed their test.

This shows that their algorithm does not detect the existing fault.

This is not to say that their algorithm is Liu Xin algorithm, no matter how bad, it must be Almost Qi Ying man that degree.

Now that there is an opportunity, try to do it with Lin yuejing's dirty brain.

"This is the plan, but it may not be very good to use the LSSVM toolkit directly. It is also necessary to optimize the rocket data, so PSO particle swarm optimization is found." Li Zheng put down the chopsticks and said calmly, "you know, I have to understand all the principles of what I do. Some mathematical problems of the algorithm itself are a little difficult to chew."

"Wait a minute. I'll ask you Mr Shen." Lin Passover Jing picked up his mobile phone and played it for a while. After half a minute, he turned to Li Zheng and smiled, "sure enough, someone has done it in the 11th day. They have about four or five algorithms. What SM should be included in it?"

“……” Li Zheng's face trembled.

"Huh..." Lin Yu, quietly, looked down at him, "as if you found something terrible, like a civil servant."

"First, whether civil or non-governmental, what algorithms have they adopted? How to optimize? "

"Who knows that." Linyue Jingchong machine room worked hard, "anyway, we use this data analysis system, but they do it."

"Yes Since that... "" Li Zheng knead the head, "they changed several parameters and then went on a few times."

"They're doing it. Who said they didn't?"

"So what are our test teams doing here?"

"Yes," Lin Yue said, humming, "so I didn't do anything. I looked at the rocket map myself. Take this as the computer room where I can go to the intranet database."

"You too, this is also..." Li Zheng wants to say that he is doing nothing.

But think about it carefully. As a person who has not even entered the line, learning knowledge as soon as possible is the most active practice.

It was myself, like a chicken blood.

"Then I'll learn for a few more days." Li Zheng wiped the rice grains from the table into the dinner plate. "I know that every small thing has a special team to devote great energy to do. The professional field is too much and too deep, and one person has too little energy."

"Oh, you don't mean to work out cooperation?" Lin yuejing also sorted out the table and said, "once you do it, you will make a car closed to the door like learning?""I just invited you to cooperate."

"I'm a ball. I'm still looking at the rocket chart." Lin Qijing said, taking out his mobile phone and lighting it to Li Zheng, "your teacher Shen has encouraged your learning direction. This is the contact information of 11 docking technicians. She just said hello to you."

"Oh?" Li Zheng eye son a stare, "your mother also thinks this optimization algorithm?"

"Your mother thinks it!" "Miss Shen, please call me Miss Shen!" Lin said

"Yes, yes, I'd better call a teacher in the unit."

"Well, you have to remember." Lin Qijing picked up the plate and said, "I have time to look at the popular algorithm in the afternoon, just look at it casually, and it won't be too serious."

"That's very kind of you." Li Zheng then got up to pick an eye, "take advantage of the lunch break, go out for a walk and relax?"

"No, I'm going back to the computer room and sleeping."

"Well, I went five kilometers by myself."

They handed in their plates.

I'm going to go my separate ways. One goes to the computer room and the other goes to the courtyard.

Lin Qiaojing suddenly felt the three anxious eyes cast behind him.

It's three engineers. They've finished eating, and they're looking at this side with hostility.

It's over. It still makes them angry.

If you go back to the computer room and sleep I'm afraid it's even more angry?

Lin Qijing shivered and ran out after Li Zheng: "wait for me..."

After that, the three engineers were more lonely.

Even a few minutes, do not want to share a room

Life is often like this, even if the day drop female high school students, it will not be related to you.

Instead, they will fall to the bottom of the valley because they are rejected.

The three could not help looking at each other.

There's no such thing as a high school girl.

Only we can be with each other for a long time.

"Do you want to go for a walk..."

"Let's go. It's been a long time since I've been eating like this."

"Wait I always feel more stimulated... "

"So Ah There's no place to live. Director Chen is really going to kill us. "

"No, there's another place." High volume engineers stare at the other two and raise their hands angrily, "King's Canyon!"

"Also Only there

"Let's go back to the canteen and have a fight..."

So, why there are so many people in the king's gorge, it has a reason.

……

At 1:30 p.m., Li Zheng, according to the contact information given by Shen Tinglan, found a software engineer from 11 research institutes and a department.

Because Mr. Shen has already said hello and has a good attitude towards him, he told Li Zhengyuan the current situation of artificial intelligence fault diagnosis.

It's a new field, after all, and it's changing every day.

And the strongest people in this field will definitely go to IT enterprises. They can't choose from aerospace.

Therefore, the main way to carry out the work here is to cooperate with the laboratory of the University.

Although the software of fault diagnosis is developed by 11 research institutes, the core algorithm is mainly developed and improved by two university laboratories. They have regular communication feedback to optimize.

In view of Huang er's situation, they have carried out several optimization adjustments, but still do not get a clear result, and the relevant diagnostic materials have already been sent to the technical team.

Finally, he also sent relevant algorithm data and analysis data to he Zhongrui's internal mailbox. Li Zheng is welcome to make suggestions.

Thanks again and again, Li Zheng hung up the phone.

Now it seems that this road may not be feasible.

But at least there is something to learn.

At this time, Lin Yue Jing also has a general understanding of several mainstream algorithms.

It wilted immediately.

"No way Give me more than half a year, it's almost like... " Lin Yujing, holding his head on the back of his chair, sighed, "it's not so difficult to understand the principle, but it needs a lot of trying and accumulating to optimize this kind of thing This is what the lab does Hate computers, hate programmers... "

"What if you're only responsible for optimization?" Li Zheng asked.

"Optimization is also to try again and again, not a pat on the head can become." "Many times, we have to adjust the combination of various parameters and details repeatedly, and accumulate a lot of results to find the temporary optimal direction."

Li Zheng thought for a while and said, "take a step back, do you only provide optimization ideas?"

"What's the use of that?" Lin Yujing opened his arms like a monster. "I tell you, go to nuclear fusion, and you can do it?"

"No, no, this is ten thousand steps back..." Li Zheng still explained seriously, "you should at least tell me the fuel and realization method of nuclear fusion, and I will find materials and structures."

"Well, the raw material is deuterium, and the method is inertial restraint. You can do it.""Well Li Zheng sighed and his attention returned to the screen in front of him I'll do it with the big brother of the 11th Research Institute. You can clear the mines. "

“……” Lin Qijing was sullen, but he didn't know what to say. He had to open a super large Minesweeper and began to be blind.

She ordered a few times, how to point how to die, she was angry to turn off the Minesweeper, opened the rocket structure diagram and began to appreciate.

What's annoying is that the rocket doesn't smell good after watching too much.

The more you think about it, the more angry you get, the more you think about it.

After a few minutes of sulking, Lin yuejing couldn't hold back and stepped on Li Zheng.

"Well?"

Lin yuejing turned her head and struggled for a while before saying: "I'm sorry My mother gave the informant, you don't take me

"Don't you participate yourself?" Li Zheng scratched his head and asked.

"When did I say no more?"

"Don't you mean not to participate..." Li Zheng chuckled, "I understand, for this kind of hard to have any result, but also to pay a lot of efforts, learning you do not like knowledge, you must not be able to carry, forget it, mine clearance, good."

"This..." Lin Qijing scratched the table with two hands and struggled, "algorithm or something I don't like chemistry so much In astronomical deduction, algorithms are also used... "

Li Zheng did not dare to look forward to asking: "that is Participated? "

"I didn't say that."

"That's not participating?"

"I didn't say it!"

After a moment of confusion, Li Zheng finally understood.

"I see. You want me to ask you to participate."

"I didn't say ~"

"Oh, that's fine." Li Zheng waved his hand with a smile, "go to mine clearing, don't disturb my study."

“！！” Lin Qijing stamped his foot again. "If you don't take me, I'll let my mother tell the people of the 11th Research Institute not to pay attention to you!"

“？？？” Li Zheng's eye son one stare, "is not said that does not touch your mother's light?"

"Your mother's light!"

"It's the light of Mr. Shen It's agreed not to do this. "

"I, no, say it!"

"You're so boring..." Li Zheng tangled, "not only disturb my study, but also prevent me from working."

"That's it." Lin Yue Jing waved his fist and said, "with or without?"

"All right, all right, take it, do it together."

"Add a please word!"

"Please do it together..."

"Add a word

"Please do it together."

"Oh, no way." Lin Qijing covered his face and said with a smile, "slag is so poor, I'll help you ~"

"Damn it." Li Zheng beat the table, "the status obtained by this method is hypocritical. This position is not yours, it is your mother's

"Curse again!"

Just as he said, he Zhongrui finished his rest, washed his face and entered the computer room. He did not care about the three, but went straight to Li Zheng.

"How about it? Is it all right? "

"Finished coexisting to the specified location." Li Zheng nodded and stood up and said, "in addition, I asked for some learning materials from the teachers of 11 institutes, which were sent to your intranet mailbox. It's hard for teacher he to help with it."

"Eleven? They are mainly engaged in software... " He Zhongrui thought for a while and then said, "Oh, oh, Zhou Chenglong has contacted you?"

"What?"

"Hi, I told the director that you have a good foundation and learn fast." He Zhongrui patted Li Zheng and said with a smile, "Congratulations, you should go to the technical group soon."

"Ah?" Li Zheng was stunned.

"Ah?" Lin Yu is in a hurry.

Although it was Li Zheng's target team, it was hard to bear to leave Lin Qijing alone here.

Lin Yue Jing is unable to accept the fact that Li Zheng is now transferred to the target team.

As for he Zhongrui, he only saw a couple of men and women who couldn't bear to be separated.

"You Is it... " He Zhongrui swallows a mouth to spit a way, "Li Zheng, you don't want to go?"

"I want to finish more work..." Li Zheng scratched his head and said, "can we go next week?"

He Zhongrui took another look at Lin Yue Jing.

She is also a low head unwilling to give up the appearance.

Damn it.

Isn't it just classmate friendship?

It's like I won't let you two sleep in the same bed!

Under strong sensory stimulation, he Zhongrui swallowed a mouthful of sour water.

"Well Let me talk to Jackie Chow again I want you to report back later... " He Zhongrui side head ferocious eye way, "the task that hand over to you can not be little."

"That must be."

"Xiao Lin, you too..." He Zhongrui turned his head and said, "I heard that you want to go to the design group, right? If you don't want to spend time here, you should take the initiative to ask for some materials and learn more after work. I also mentioned it to them almost at the same time.""Thank you, Mr. He..."

"All right, all right." He Zhongrui heaved his arm and said, "go to work."

There's something he thinks 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 at the three colleagues, he Zhongrui read the same understanding in their eyes.

Now the situation has changed. It is no longer how to keep Lin Yujing.

For the safety of the brothers' lives, we have to find a way to leave her!
