In LSSVM algorithms, when you hear the word "algorithm", you can basically determine that it originated in the field of machine learning.

In this field, although all kinds of algorithms are enchanting, there are thousands of styles.

However, machine learning ultimately has to be implemented into the word "learning".

As long as it is implemented here, it must be within Li Zheng's range.

In fact, even its basic principles are no different from Li Zheng's learning.

Li Zheng, use his brains, do a lot of papers, and then improve the knowledge points, so that no matter what kind of college entrance examination papers he does, he can get a score of 730+.

This is a complete Li Zheng study, the purpose of which is to pass the college entrance examination and rank above Lin Yujing.

The machine, on the other hand, uses a certain mathematical model to infer a large number of rocket launch data, and then improves the calculation method to achieve that no matter what kind of rocket parameters are obtained, it can guess and diagnose faults with an accuracy rate of higher than 95%.

This is a complete machine learning that aims to find the point of failure and ensure the success rate of the rocket launch.

But even with this simple principle, machine learning is still a deep field.

No way, the difficulty is all in the algorithm.

also take Li Zheng's study as an example.

Without considering the bonus of learning demons, its efficiency and results depend on Li Zheng's IQ and learning methods, referred to as learning methods.

Then in the same time, put Li Zheng, Lin Yujing and Liu Xin together to study.

The result must have been very different.

On the one hand, everyone has different IQs, and Liu Xin may not learn it at all.

On the other hand, everyone's methods are also different, Lin Yujing, a person who is cheating and cheating, no matter what knowledge he faces, he will definitely be able to come up with a dirty learning method.

Therefore, under normal circumstances, the final result of the three will be-

Lin Yujing ≥ Li Zheng...... Liu Xin.

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

As long as you shout "AMD, YES!", the CPU will instantly become stronger.

The rest of the highlights are all focused on algorithms.

LSSVM is only one of the more popular ones, in addition to the traditional voice, image recognition and other fields, it is also gradually applied in nuclear power plants, petrochemical industry, system control and other fields of fault detection.

However, in the space system, for the time being, it is still dominated by traditional models and expert systems.

Within the system, there are naturally institutes that study this direction.

The problem is that Huang Er has already passed their test.

This shows that their algorithm is not aware of the existing faults.

Of course, this does not mean that their algorithm is Liu Xin's algorithm, no matter how bad it is, it has to be ...... It's about the same level as Qi Yingnan.

Since there is an opportunity in front of him, it is better to try to use Lin Yujing's dirty brain to do it.

"That's the plan, but the off-the-shelf LSSVM toolkit may not work very well directly, and there are some optimizations to be made for the rocket data, so I found PSO particle swarm optimization. Li Zheng put down the dishes and chopsticks and said calmly, "You know, I have to figure out all the principles of everything, and some mathematical problems of the algorithm itself are a bit difficult." ”

"Wait, I'll ask you, Mr. Shen. Lin Yujing picked up the phone and fiddled with it, and after waiting for half a minute, she turned her head and smiled at Li Zheng, "Sure enough, the eleven institutes you said have already been done, they probably have four or five algorithms, which should include this or something." ”

"......" Li Zheng's face trembled.

"Hmm......" Lin Yujing covered her mouth and looked at him with contempt, "Just like you, it seems that you have discovered something amazing, like a civil science." ”

"Regardless of whether it is a civil science or not, what specific algorithms do they use, and how do they optimize it?"

"Who knows. Lin Yujing pouted at the computer room, "Anyway, the data analysis system we use now is also made by them." ”

"Yes...... Since that's the case......" Li Zheng rubbed his head and said, "They just change a few parameters and go through it a few times." ”

"They're doing it, and who's to say they don't?"

"So what is our test team doing here?"

"Yes~" Lin Yujing snorted and said, "So I didn't do anything, I looked at the rocket map by myself, and I used this as a computer room that can be used as an intranet database." ”

"You too, this is also ......" Li Zheng wanted to say negative sabotage or something.

But if you think about it, as a person who has never even entered the industry, it is already the most positive way to learn knowledge as soon as possible.

On the contrary, it was himself, as if he had been beaten with chicken blood.

"Then I'll study for a few more days. Li Zheng wiped the rice grains on the table on the plate, "I really know that every little thing has a special team to invest a lot of energy to do, there are too many professional fields, and one person's energy is too little." ”

"Heh, didn't you say that you want to exercise cooperation?" Lin Yujing also sorted out the desktop and said, "As soon as you do it, it's like learning behind closed doors again?"

"Didn't I just invite you to cooperate? ”

"I'm a ball, and I'm still looking at the rocket. Lin Yujing said and took out her mobile phone and lit it up to Li Zheng, "Your teacher Shen encouraged your study direction, this is the contact information of the eleven docking technicians, she greeted you just now." ”

"Oh?" Li Zheng's eyes widened, "Your mother also thinks the optimization algorithm should be optimized?"

"Your mother just thinks it!" Lin Yujing lit the table and said, "Teacher Shen, call Teacher Shen!"

"Yes, yes, it's better to call it a teacher in the unit. ”

"Alright, you have to remember. Lin Yujing picked up the dinner plate and said, "I have time to look at the current popular algorithm in the afternoon, so I will take a look at it casually, I won't take it too seriously." ”

"That's a good idea. Li Zheng then got up and picked his eyes, "Take advantage of the lunch break to go out for a walk and relax?"

"No, I'm going back to the computer room to sleep. ”

"That's it, I'll go five kilometers by myself. ”

The two handed over the plate.

Seeing that they were about to part ways, one went to the computer room and the other went to the hospital.

Lin Yujing suddenly felt three anxious glances behind her.

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

It's over, and it's still them off.

If you go back to the computer room and sleep now...... I'm afraid I'm even more angry, right?

Lin Yujing shuddered, chased Li Zheng and ran out: "Wait for me ......"

Behind them, the three engineers were even more lonely.

I don't want to be in the same room for even a few minutes......

Life is often like this, even if it is a high school girl from the sky, it will not be related to you.

On the contrary, because of being disliked, he will fall to a deeper bottom.

The three couldn't help but look at each other.

Female high school students or something, they don't exist.

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 eaten like this. ”

"Wait...... I always feel like I'm going to be more stimulated......"

"So...... Ay...... There's no place to stay, Director Chen really wants to kill us. ”

"No, there's another place. The high-volume engineer stared at the other two and raised his hand angrily, "King's Canyon!"

"Also...... Only there......

"Let's go, go back to the cafeteria and ......"

So, there is a reason why there are so many people in King Canyon.

......

At half past one in the afternoon, Li Zheng followed the contact information given by Shen Tinglan and found a software engineer from the eleventh institute that was connected with the first department.

Because Mr. Shen had already said hello, he had a good attitude on the other side, and told Li Zheng about the current situation of artificial intelligence fault diagnosis.

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

And the strongest person in this field will definitely go to IT companies, and it is not the turn of aerospace to pick.

Therefore, the main way to carry out the work here is to cooperate with the university's laboratories.

Although the software for fault diagnosis was developed by 11 institutes, the core algorithm was mainly developed and improved by two university laboratories, and they had regular feedback to optimize it.

In response to Huang Er's situation, they have made several optimization adjustments, but they still have not got clear results, and the relevant diagnostic materials have already been sent to the technical team.

Finally, he also sent the relevant algorithm data and analysis data to He Zhongrui's internal mailbox, and welcomed Li Zheng to refer to it and make suggestions.

Li Zheng thanked him again and again before hanging up the phone.

Now it seems that this road may not necessarily work.

But there's something to learn.

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

It wilted immediately.

"Impossible...... Give me more than half a year, it's about ......," Lin Yujing covered her head and leaned back in the chair and sighed, "It's not that difficult to understand the principle, but optimizing this kind of thing requires a lot of trial and accumulation...... That's what the lab does...... Hate computers, hate programmers......"

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

"Optimization is also a matter of trial and error, and it is not something that can be achieved with a pat on the head. Lin Yujing gestured, "Many times, it is necessary to repeatedly adjust the combination of various parameters and details, and accumulate a lot of results to find the temporary optimal direction." ”

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

"What's the use of that?" Lin Yujing opened her arms like a monster, "Ahh

"No, no, this is 10,000 steps back...... Li Zheng still explained seriously, "You must at least tell me the fuel and the method of achieving nuclear fusion, and I will find materials to build the structure." ”

"Okay, the raw material is deuterium, and the method is inertial constraint, you can do it. ”

"Okay...... Li Zheng sighed, and his attention returned to the screen in front of him, "Forget it...... I'll work with the eldest brother of the eleventh institute, and you can sweep mines. ”

"......" Lin Yu was sullen, but he didn't know what to say, so he had to open a super-large minesweeper and began to be blind.

After a few clicks, how to order and how to die, she was so angry that she turned off the minesweeper, opened the rocket structure diagram and began to admire.

What I hate is that this rocket doesn't smell good if you watch it too much.

The more I think about it, the more angry I get, and the more angry I get, the more I think.

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

"Huh?"

Lin Yujing turned her head and struggled for a while before saying, "...... The informant was given by my mother, and you don't take me!"

"Isn't it that you don't participate yourself?" asked Li Zheng, scratching his head.

"When did I say I wasn't involved?"

"Don't you mean not to participate......" Li Zheng chuckled, "I understand, for this kind of difficulty, what is the result, and you have to make great efforts, learn things you don't like to know, you will definitely not be able to bear it, forget it, minesweeper, it's good." ”

"This ......," Lin Yujing struggled with scratching the table with both hands, "Algorithm or something...... I don't like chemistry as much...... In astronomical deduction, algorithms are also used......"

Li Zheng didn't dare to look forward to it too much and asked, "That's ...... Involved?"

"I didn't say it. ”

"That's not involved?"

"I didn't say it!"

After Li Zheng was confused for a moment, he finally understood.

"I see, you want me to beg you to participate. ”

"I didn't say it~"

"Oh, forget it. Li Zheng smiled and waved his hand, "Go to minesweeper, don't disturb my study." ”

Lin Yujing stomped her foot again, "If you don't take me, I'll let my mother tell the people of the Eleventh Institute not to pay attention to you!"

"???" Li Zheng's eyes widened, "Didn't you say that you wouldn't touch your mother's light?"

"Fuck your light!"

"It's Teacher Shen's light...... I said that this is not allowed. ”

"I, no, said!"

"You're boring...... Li Zheng said entangledly, "not only disturbing my study, but also preventing me from working." ”

"It's that powerful. Lin Yujing waved his fist and said, "Do you want to bring it?"

"Okay, okay, let's do it together. ”

"Add a word please!"

"Please do ...... together"

"Add a word!"

"I beg you to do it. ”

"Oh, I can't help it. Lin Yujing covered her face and smiled, "The scum is so pitiful, I'll help~"

". Li Zheng pounded the table, "The status obtained in this way is hypocritical, this status is not yours, it is your mother." ”

"Scold again!"

As he was talking, He Zhongrui finished resting, washed his face and entered the computer room, ignoring the three of them, and walked straight to Li Zheng's side.

"How's it going?"

"It's done and saved to the specified location. Li Zheng nodded and got up and said, "In addition, I asked the teachers of the eleventh institute for some learning materials, which were sent to your intranet mailbox, and I worked hard for Mr. He to help with them." ”

"Eleven, they are mainly engaged in software...... He Zhongrui thought for a while before saying, "Oh, Zhou Chenglong has already contacted you?"

"What?"

"Hey, I told the director that you have a good foundation and learn quickly. He Zhongrui patted Li Zheng and smiled, "Congratulations, you should be going to the technical group soon." ”

"Huh?" Li Zheng was stunned.

"Huh?" Lin Yu was anxious.

Although that was Li Zheng's target team, it always felt unbearable to leave Lin Yujing here alone.

Lin Yujing can't 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 couldn't bear to be separated.

"You ...... Isn't it ......" He Zhongrui swallowed and foamed, "Li Zheng, don't you want to leave?"

"I want to get some more work done...... Li Zheng scratched his head and said, "Can you leave next week?"

He Zhongrui glanced at Lin Yujing again.

She also looked unwilling and reluctant to bow her head.

Fuck you.

Isn't it just a classmate friendship?

It's like I don't want you two to sleep in the same bed!

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

"That'...... Let me tell Zhou Chenglong again...... Let you report later......" He Zhongrui said with a sinister look, "The task assigned to you will not be less." ”

"That definitely. ”

"Xiaolin, you are also ......" He Zhongrui turned his head strongly, "I heard that you want to go to the design team, right, if you don't want to spend it here, take the initiative to ask for some information, study more after work, and I will also mention it to them when it is about ......"

"Thank you, Mr. He......"

"Alright, alright. He Zhongrui waved his arms bitterly and said, "Go to work." ”

There was one thing, he thought wrong.

For a simple female high school student, that does have the effect of promoting work.

But if it appears with the object.

That would be a disaster for everyone.

Looking at the three colleagues again, He Zhongrui read the same insight from their eyes.

Now the situation has changed, and it is no longer how to keep Lin Yujing.

For the sake of the brothers' lives, we must find a way to get rid of her!
