Learning Demon Cultivation System

Their sadness is too superficial, like untalented actors.

The more important the scene is, the more I can't cry.

Finally, after finishing the work at hand, they walked into the small cafeteria together, as if they had been injured, they avoided Li Zheng and Lin Yujing far away, and only found a table in the corner.

Li Zheng felt something was wrong, chewed the bun and asked, "Why are they sitting so far away?"

"Probably because I hate you, hehe..." Lin Yujing thought she had successfully dug a hole for Li Zheng, and choked back her laughter.

"How could that be?" Li Zheng shook his head and said, "Probably the technicians are more introverted... Speaking of which, I'm actually very introverted too, and it will take me a while to get used to it."

"That's right, that's what scumbags say about themselves." Lin Yujing asked after taking a few bites, "Your character, shouldn't you ask for more work after work is done?"

"Am I cheap..."

"Isn't that how you study!"

"Is this the same as studying?" Li Zheng shook his head and sighed, "I probably know the process. It is to check a large amount of experimental data according to a set of standards in the group. It is boring, boring, mechanical, and a waste of life. And here is the data analysis. The software is not very easy to use, I want to make one myself..."

"Ha." Lin Yujing raised her head and took a sip of the soup, "When I heard the word test, I knew it must not be a fun job."

"I think there is something wrong with this set of data screening standards..." Li Zheng also took a sip of soup and pondered, "If you can find the problem with a set of data templates, then you must have discovered it long ago, no It may not be exposed until the launch, and to find problems that could not be found before, we need to change our thinking."

"Well, that's what my mother said too." Lin Yujing quietly leaned forward, "It's just that Director Chen must do this..."

"Well...the director has such a high level, there must be his intentions." Li Zheng thought for a while but couldn't figure it out, and said with a babble, "Anyway, I just finish the scheduled workload and treat it as a school job. Some particularly boring homework, I will learn more in the extra time, and try to go to the technical group as soon as possible.”

"Scumbag, I just figured it out?" Lin Yujing snorted and said with a smile, "I thought about it from the beginning, so I only do document sorting, and I spend all the extra time looking at the rocket map in the system."

"Why do I think you just want to be lazy..."

"If I'm lazy, I'll play minesweeper."

"No, minesweeping is a mathematical thinking exercise." Li Zheng leaned forward as he spoke, "However, I have to sort out the test data anyway. I have an immature idea."

"I do not want to hear."

"Listen to it..." Li Zheng rubbed his hands together, "Have you heard of the LSSVM algorithm?"

"???"

"It's a mathematical algorithm, which is mostly used for artificial intelligence neural network learning. I happened to read two English papers in the system in the morning, and then I realized that this algorithm can also be used for fault detection. In the case of Huang Er, this The algorithm is combined with the PSO particle swarm optimization algorithm, that is, put it together for a while, and there should be something."

"Hmm..." Lin Yujing said with grim eyes, "So... I hate studying with you..."

"Listen to me, I understand the concepts, ideas and uses of these two algorithms." Li Zheng said seriously, "But when it comes to the algorithm itself... I can't learn it..."

"?!" Lin Yujing exclaimed in surprise, "You have today too!"

"No way, this part of the content is too professional. The calculation process in the information is for doctors of mathematics. If it is too omitted, it is equivalent to me explaining math problems to Liu Xin and chatting with him..." Li Zheng flickered Blinking her big eyes, "Why don't you... take a bite of the algorithm part... I'll do the architecture and programming, our entire small program, and take a look at these test data?"

"This kind of work..." Lin Yujing narrowed her eyes and said, "It's done by the math laboratory..."

"Whatever." Li Zheng knocked on the table with a smile, "We're already in Rocket Lab."

"Then..." Lin Yujing swallowed and asked, "Say it again, what is that algorithm called, L what SM?"

"It's not SM, it's VM! LSSVM!"

Chapter 293 I have to find a way quickly

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

In this field, although various algorithms are all kinds of enchanting and charming.

However, machine learning must ultimately be implemented in the word "learning".

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

In fact, even the basic principles are the same as Li Zheng's study.

Li Zheng used his brain to do a lot of papers, and then perfected the knowledge points, so that no matter what kind of college entrance examination paper he did, he could get a score of 730+.

This was a complete study for Li Zheng, with the goal of passing the college entrance examination and ranking above Lin Yujing.

The machine, using a certain mathematical model, speculates a lot of rocket launch data, and then improves the calculation method, so that no matter what rocket parameters it gets, it can speculate and diagnose faults, and the accuracy rate is higher than 95%.

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

But even though the principle is so simple, machine learning is still a profound field.

No way, the difficulty lies in the algorithm.

Take Li Zheng's study as an example.

Without considering the bonus of learning magic, 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 Yujing and Liu Xin together to study.

The result must be very different.

On the one hand, everyone's IQ is different, and Liu Xin might as well not learn it if he has learned it.

On the other hand, everyone's methods are also different. A sneaky person like Lin Yujing, no matter what kind of knowledge he faces, can definitely come up with dirty ways to study it.

Therefore, under normal circumstances, the final results 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.

As for the CPU computing power, there are dedicated people to do it. Just shout "AMD, YES!", and the CPU will instantly become stronger.

The rest of the highlights will all focus on the algorithm.

LSSVM is only one of the more popular ones. In addition to traditional speech and image recognition, it is also gradually applied in fault detection in nuclear power plants, petrochemicals, and system control.

But in the aerospace system, the traditional model and expert system are still the main ones for the time being.

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

The problem is that Huang Er has passed their test.

This shows that their algorithm did not detect existing faults.

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

Since there is an opportunity in front of you, why not try to use Lin Yujing's dirty mind.

"That's the plan, but the off-the-shelf LSSVM toolkit may not be very effective if you use it directly, and you need to do some optimization for the rocket data, so you found PSO particle swarm optimization." Li Zheng put down his bowl and chopsticks, and said calmly, "You know, I have to figure out all the principles of everything I do. Some mathematical problems in the algorithm itself are a bit difficult to crack."

"Wait, let me ask you, Teacher Shen." Lin Yujing picked up her phone and fiddled with it. After waiting for half a minute, she turned her head and smiled at Li Zheng, "Sure enough, the eleventh school you mentioned has already Some people have done it, and they probably have four or five algorithms, which should include this SM."

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

"Huh..." Lin Yujing covered her mouth and came over with contempt, "With your appearance, it seems that you have discovered something extraordinary, like a civil servant."

"Let's not care about Minke or not, what algorithms did they use? How were they optimized?"

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

"But...in this case..." Li Zheng rubbed his head and said, "They just need to change a few parameters and try again a few times."

"They are doing it, who said they haven't?"

"Then what is our testing group doing here?"

"Yeah~" Lin Yujing hummed and said, "So I didn't do anything, I looked at the rocket map by myself, so I just use this as a computer room where I can access the intranet database."

"You too, this too..." Li Zheng wanted to say something like sabotage.

But if you think about it carefully, as a person who has not even entered the profession, learning knowledge as soon as possible is the most positive way.

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 that fell on the table into the dinner plate, "I don't know until I really do it. Every little thing has a dedicated team that puts a lot of energy into it. There are too many professional fields. Too much is too deep, and one person's energy is too little."

"Heh, didn't you say you want to practice cooperation?" Lin Yujing also tidied up the desktop and said, "Once you start doing it, you will be working behind closed doors like learning?"

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

"I'm a baller, I'm still looking at the rocket map." Lin Yujing said as she took out her mobile phone and flashed it to Li Zheng, "Your Teacher Shen encouraged your study direction, this is the connection with the technicians of the Eleventh Institute Way, she greeted you just now."

"Oh?" Li Zheng stared, "Your mother also thinks that the algorithm should be optimized?"

"Your mother thinks so!" Lin Yujing pointed at the table and said, "Mr. Shen, it's Mr. Shen!"

"That's right, it's better to be called a teacher in the unit."

"Okay, you have to remember." Lin Yujing picked up the plate and got up and said, "I have time in the afternoon to look at the current popular algorithms, just look at it casually, I won't take it too seriously."

"That's a good thing." Li Zheng stood up and raised his eyes, "Would you like to take a walk during the lunch break to relax?"

"No, I'm going back to the computer room to sleep on my stomach."

"That's it, I went five kilometers by myself."

The two handed over the plate.

It was about to part ways, when one went to the computer room and the other went to the courtyard.

Lin Yujing suddenly felt three anxious gazes from behind.

It was the three major engineers who had also finished eating and were looking at this side full of hostility.

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

If I go back to sleep in the computer room now... I'm afraid I'll be even angrier?

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

Behind them, the three engineers became even more lonely.

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

Life is often like this, even if the girl is a high school girl from heaven, it will not have anything to do with you.

On the contrary, because of being rejected, they will fall to a deeper abyss.

The three couldn't help looking at each other.

There is no such thing as high school girls.

Only we can stay together for a long time.

"Would you like to go for a walk..."

"Let's go, it's been a long time since I digested food like this."

"Wait... I always feel that I will be more stimulated..."

"Speaking of it... hey... there is no place to stay, Director Chen is really going to kill us."

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

"Also... only there...

"Go, go back to the cafeteria and fight..."

Therefore, there are reasons why there are so many people in the Canyon of Kings.

……

At 01:30 in the afternoon, according to the contact information given by Shen Tinglan, Li Zheng found a software engineer who was connected with the First Eleven Institute.

Because Mr. Shen had already said hello, and he had a very good attitude, and explained the current situation of artificial intelligence fault diagnosis to Li Zheng.

After all, this is a new field and changes every day.

And the strongest person in this field will definitely go to an IT company, and it is not the turn of Aerospace to choose.

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

Although the fault diagnosis software was developed by the [-]th Institute, the core algorithm is mainly developed and improved by two university laboratories, and they have regular communication and feedback for optimization.

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

Finally, he also sent the relevant algorithm information and analysis information to He Zhongrui's internal mailbox. Li Zheng is welcome to refer to it for suggestions.

Li Zheng thanked him repeatedly before hanging up the phone.

Now it seems that this road may not be feasible.

But at least there is something to learn.
