In the lssvm algorithm, when you hear the word "algorithm", you can basically determine that it originated from 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 its basic principles are no different from those studied by Li Zheng.

Li Zheng used his brain to write many papers, and then improved his knowledge points, so that no matter what kind of college entrance examination papers he took, he could get a score of 730+.

This is a complete study for Li Zheng. The purpose is to pass the college entrance examination and rank higher than Lin Yujing.

The machine uses a certain mathematical model to infer many pieces of rocket launch data, and then improves the calculation method so that no matter what rocket parameters it gets, it can guess and diagnose faults with an accuracy higher than 95%.

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

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

There is no way, the difficulty lies entirely in the algorithm.

Let’s 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, which is referred to as learning method.

Then let Li Zheng, Lin Yujing and Liu Xin study together at the same time.

The result must be very different.

On the one hand, everyone has different IQs, so Liu Xin might be better off not learning if he learned.

On the other hand, everyone's methods are also different. People like Lin Yujing, who are sneaky and slippery, will definitely be able to come up with dirty ways to learn no matter what knowledge they face.

Therefore, under normal circumstances, the final results of the three people 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 CPU computing power, there are dedicated people who are busy with it. 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 traditional speech and image recognition and other fields, it has also been gradually used in fault detection in nuclear power plants, petrochemical industry, system control and other fields.

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

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

The problem is that Huang Er has passed their test.

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

This certainly does not mean that their algorithm is Liu Xin's algorithm. No matter how bad it is, it has to be... almost the same as Qi Yingnan's.

Now that there is an opportunity in front of us, why not try to use Lin Yujing's dirty mind to do it.

"This is the plan, but the effect of using the ready-made lssvm toolkit directly may not be very good. Some optimizations need to be done for rocket data, so I found pso particle swarm optimization." Li Zheng put down the bowl and chopsticks and said calmly,

"You know, I have to understand all the principles of anything I do. Some of the mathematical problems in the algorithm itself are a bit difficult to deal with."

"Wait a minute, let me ask you, Teacher Shen." Lin Yujing picked up her phone and fiddled with it for a while. After waiting for half a minute, she turned to Li Zheng and smiled, "Sure enough, this Eleventh Institute you mentioned has been around for a long time.

Someone has done it, and they have about four or five algorithms, which should include this and so on."

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

"Uh-huh..." Lin Yujing covered her mouth and came over with contempt, "You look like you have discovered something extraordinary, like a civil servant."

"Regardless of whether it is civil science or not, what specific algorithms did they use? How to optimize it?"

"Who knows." Lin Yujing pursed her lips towards the computer room, "Anyway, the data analysis system we are using now was also made by them."

"But... in this case..." Li Zheng rubbed his head and said, "They can just change a few parameters and re-run it a few times."

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

"Then what are our test teams doing here?"

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

"This is what you are doing..." Li Zheng wanted to say something like being passive and sabotaging work.

But if you think about it carefully, as someone who has never even entered the industry, learning knowledge as soon as possible is the most positive thing to do.

On the contrary, it was me, as if I had been injected with chicken blood.

"Then I'll study for a few more days." Li Zheng wiped the rice grains that fell on the table onto the dinner plate, "Only when you really do it do you realize that every little thing has a dedicated team putting in huge energy to do it. The professional field is too

It’s too much and too deep, and one person’s energy is too little.”

"Oh, didn't you say you wanted to practice cooperation?" Lin Yujing also tidied the table and said, "Once you start working, it's like studying behind closed doors again?"

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

"I'm just a kid, I'm still looking at the rocket diagram." Lin Yujing said, taking out her phone and showing it to Li Zheng, "Your teacher Shen encouraged your study direction. This is the contact with the technical personnel of the 11th Institute.

Well, she just said hello to you."

"Oh?" Li Zheng glared, "Does your mother also think the algorithm should be optimized?"

"That's what your mother thinks!" Lin Yujing pointed at the table and said, "Teacher Shen, call me Teacher Shen!"

"That's right, I'd better call you teacher in the workplace."

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

"That's great." Li Zheng stood up and asked, "While you're on lunch break, why don't you go out for a walk and relax?"

"No, I want to go back to the computer room and sleep on my stomach."

"Okay then, I'll go five kilometers by myself."

The two handed over their plates.

When they were about to part ways, one went to the computer room and the other to the courtyard.

Lin Yujing suddenly felt three anxious looks from behind.

It was the three major engineers. They had also finished eating and were looking at this side with hostility.

After all, I still made them angry.

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

Lin Yujing trembled and ran outside after Li Zheng: "Wait for me..."

Behind them, the three engineers felt even more lonely.

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

Life is often like this, even if a female high school student falls from the sky, it will not have anything to do with you.

Instead, they will fall deeper into the valley because they are rejected.

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

There is no such thing as a female high school student.

Only we can stay together for a long time.

"Would you like to take a walk..."

"Let's go, I haven't eaten like this for a long time."

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

"Let's put it this way... ugh... there's no room for us anymore. Director Chen really wants to kill us."

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

"Also...that's the only place...

"Let's go back to the cafeteria and give it a beating..."

Therefore, there is a reason why there are so many people in Kings Canyon.

…

At 1:30 in the afternoon, Li Zheng followed the contact information given by Shen Tinglan and found the software engineer from the 11th Institute who was connected with the First Department.

Because Teacher Shen had already said hello, the other person had a very good attitude and explained the current situation of artificial intelligence fault diagnosis to Li Zheng in detail.

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

The strongest people in this field will definitely go to IT companies, and it is not the aerospace industry's turn to pick them.

Therefore, the main way of carrying out work here is to cooperate with university laboratories.

Although the fault diagnosis software was developed by the 11th Institute, the core algorithm is mainly developed and improved by two university laboratories. They have regular exchanges and feedback for optimization.

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

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