Learning Demon Cultivation System

And once you really learn it.

It will only feel more terrifying.

And what Li Zheng had to deal with was not the exam, but the reality.

His first step is to reach the level of a bachelor's degree in computer science.

As a veteran programmer, this is not difficult.

The second step is to reach the level of a master's degree in machine learning.

this……

It's actually not that difficult.

However, the master's degree is also divided into a fishing master's degree and a gangster's master's degree.

As a master of Moyu, if you can pass the exam and graduate smoothly, you can just find a job.

As for the master's degree, it is necessary to master a large amount of core knowledge of the major during the study period.

Including but not limited to probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory...

Among them, the requirements for mathematics have exceeded the sum of all the competitions that Li Zheng has participated in before, which is equivalent to the amount of learning of 80 biological national funds.

Under this level of mathematical pressure, Li Zheng's study time of just over 100 hours a day is actually not enough, and Zhuangzi should have targeted him even worse.

Unexpectedly, in this desperate study intensity, a little student movement that was once very unintentional played a role.

【Learning Talent: Mathematical Brain】

[In thinking, the problem can be transformed into a mathematical problem as much as possible, and possible calculations can be completed with terrifying neural efficiency. 】

Li Zheng could only feel this talent of reconstructing mathematical thinking spelled out under the guidance of Jie Qifen, when he was doing quick calculations in his head. The initial intuitive feeling was just to enhance his computing power.

But at this time, with the deepening of mathematics research, I sneaked into various groups, and when I watched the exchanges of some masters and doctors, I just discovered the Cholesky decomposition, Laplacian matrix and normalized Laplacian matrix that have troubled everyone for a long time. Difficulties, but here I just push the boat along the way and solve it easily.

On the other hand, as the mathematical foundation becomes more and more solid, looking back at the existing algorithms given by Eleven, it will naturally become more and more smooth, and occasionally some optimization ideas will burst out.

Unknowingly, the words he said when we first met and resolved their differences did not fade with time, but became more and more clear——

"Learning mathematics well, as good as you can learn, is not only a competition, but also very important in the future."

I'm learning now, Mr. Xie.

However, even if one acquires a master's degree, it is only the second step.

The third step is practical application, which can use this knowledge to participate in the work and actually improve the fault diagnosis algorithm.

This requires a lot of project experience to accumulate, and it takes half a year to get started with 996.

But for some people, if you are still crawling in from outside the door, she has already got in like a monster without knowing when.

[There is a monster, every time you step on a floor, you find that she is still on top of you. 】

【——Lin Yujingyao】

After Lin Yujing learned 1/20 of Li Zheng's content, before Li Zheng reached the master's level, at 5:50 p.m. ], and [Fault Diagnosis of Liquid Rocket Engine Based on Comprehensive Fuzzy Clustering Algorithm] were sent to Li Zheng.

"I... I haven't learned yet..." Li Zheng looked at the patchwork algorithm document, his hand holding the mouse trembled, "Do you know what these things are?"

"I don't know it all, but I don't need to know the details." Lin Yujing kindly helped him pull down the document, "The following are some related papers. I only adopted them based on the conclusions. Thank you for understanding."

"It will take a week to figure out any one of them, okay?"

"Ah, why aren't you motivated?" Lin Yujing teased, "Didn't you finish three books in one day? Isn't it that I can't learn from you? You should learn~~"

"...Damn it, let's learn." Li Zheng gritted his teeth, "Don't lie to me, are you sure these two directions are feasible?"

"At least it's better than the current ones." Lin Yujing pointed to a row of papers on the screen, "The premise is that the data and results given by these papers are not watered down."

"Okay." Li Zheng rolled up his sleeves and said, "Try to figure it out today, and then ask Eleven for a test server."

"In addition, it is also feasible for you to do PSO optimization in the existing system." Lin Yujing moved the mouse to another document, "These are the papers and technical documents you need, I didn't read them carefully."

"Enough is enough..." Li Zheng hurriedly said, "Let's take these three paths first..."

"That's it? I'm still going to do the negative selection method. Also, have you learned the morphological classification?" Lin Yujing narrowed her eyes, "I can't feed you enough."

"I'm full, I'm going to be overwhelmed." Li Zheng quickly waved his hand, "Go and play minesweeping for a while... By the way, my mother is helping with technological construction in Africa recently, and my dad is going to participate in something... International Neurology No surgery, no one at home for three or four days, Wangcai may be starving to death, or drowning in his own feces, so I have time to take care of it.”

"!!!" Lin Yujing collapsed instantly, "You... how could you bully her like this..."

"I also want to go back and take care of it, but only here has an intranet and can connect to the test server." Li Zheng took out a bunch of keys from his bag and patted them on the table. Are there any vital signs?"

"I... I'll go to your house by myself..." Lin Yujing looked at the straight man's key chain with only pure iron rings. After struggling for a while, she suddenly pulled it away again, "It's all for the cats, don't think much about it." !"

"What time is it? I don't have the heart to think about anything else." Li Zheng returned to the screen, and turned his head after typing two lines, "By the way, don't look through my drawer."

Lin Yujing was overjoyed when she heard the words, and hurriedly carried her schoolbag: "Don't turn it over~~"

"No...Your expression is completely exposed..." Li Zheng got up and wanted to grab the key, "Give it to me, I'll take that little key..."

Lin Yujing protected the key in an instant, and fled with a kick.

"I~will~take care~good~cat~cat~"

"What the hell..." Li Zheng sat back at his desk angrily, gritted his teeth and muttered, "Forget it... Anyway, I will know sooner or later..."

……

At the same time, one hospital and one office building, the zero routine meeting was held as scheduled every half week before. ,

The meeting was chaired by Zhao Zhenhua, presided over by Chen Hongbing, and attended by Shen Tinglan and the team leaders.

As in the past, the groups report back to zeroing in on their progress.

As in the past, the person with the biggest eye bags, Zhou Chenglong from the technical team, was the first to report.

Although he was sleepy and exhausted, he still patted off the broken hair on his scalp, and he had enough energy to speak loudly.

"The data analysis work of the technical group is nearing completion, and 87% of the planned progress has been completed, which is about one and a half days ahead of the planned time."

"Up to now, two high-probability failure models and four medium-probability failure models have been proposed jointly with the Sixth Academy."

"Of the six fault models, five are pure engine faults, and the Sixth Academy has tested four, and one of them has basically completed the reproduction of Huang Er's fault."

"The last failure model is caused by the overall design of the rocket. We need to start the test at the western suburbs test site, and apply for test start preparations here."

Zhao Zhenhua suddenly asked: "What does it mean to basically complete the fault reproduction? Explain 'basic'."

Zhou Chenglong gestured and said: "In the recurring failure, the parameters of the engine are basically consistent with the situation before Huang Er's shutdown, but not completely. After all, the actual lift-off situation is more complicated, and the data of each lift-off will be different.”

"Then let me ask another question." Zhao Zhenhua then asked, "What is the probability that this failure model really matches the previous accident?"

Zhou Chenglong muttered, "Over 60%."

Zhao Zhenhua's expression dropped visibly, he wanted to say something, but he also knew that it was not easy for everyone, and he didn't want to hurt anyone.

"Secretary Zhao..." Chen Hongbing explained from the side, "Because Huang Er's rocket body has not been salvaged, we can only use various models to reproduce the accident. Just like the black box in an airplane accident, we cannot get the rocket. It will never be possible to determine the cause of the accident 100% if the black box is used, 60% is indeed low, but the limit is only about 80%.”

"The question is, how did you get this 60%?" Zhao Zhenhua clapped his hands together and said, "When the time comes to face the zero-returning review team, it can't be said that it is Zhou Chenglong's personal judgment, right?"

When Chen Hongbing heard the words, he quickly winked at Shen Tinglan and asked her to speak.

Shen Tinglan spoke up.

"There is a set of passing standards for the review of fault recurrence."

"To put it simply, it is to mathematically compare the data of the failure recurrence with the data in the actual accident, and finally obtain a recurrence accuracy rate."

"According to the data standard for fault recurrence, it can only reach 60% for the time being."

"But for me personally, I can basically be 99% sure of this accident model."

"I understand that." Zhao Zhenhua nodded and said, "I've seen this set of accident models, and it's really in line with my intuition, and it's in line with my experience in spaceflight for so many years, but the problem is that only 60% of it meets the evaluation criteria, even if it's really It is the cause of the accident, but the review cannot be passed, and the work cannot continue.”

"It's not that you can't pass..."

Just as Shen Tinglan was about to say something, Chen Hongbing suddenly raised his hand, interrupting her, and turned to look at He Zhongrui.

"Everyone has been working very intensively lately. After the technical team, we will talk about it alone. The test team will report first. After the report, one group will walk and the other group will take time to rest."

Shen Tinglan didn't say any more, Zhao Zhenhua also understood.

It's just that He Zhongrui was a little flustered when he was called out suddenly.

"For the test team... the overall maintenance work of the test site has been completed, and the test run is ready at any time."

"In addition, the primary task of our team is still to cooperate with the technical team to check the test data. Six people work in two shifts, plus two interns. This week, we made 6% of the progress."

"Oh?" Zhao Zhenhua said with a smile, "Those two kids are really good enough?"

"It's very useful...that's too good secretary..." He Zhongrui's expression gradually became complicated, and he couldn't tell whether it was sweet, bitter or sour.

It stands to reason that he should at least be happy to have two more capable people under his command, but he seems to be in hell, being tortured by a cauldron full of lemonade, and his whole body smells like Very weird.

"Hey, you say you are He Zhongrui." Chen Hongbing pointed at him and smiled, "Aren't you willing to give me someone?"

"This...Director Chen, it's hard to describe..." He Zhongrui said with a bitter face, "To tell the truth, I'm not talking ironically, our test group is small, so I really can't tolerate these two great gods..."

"Hahaha." Zhao Zhenhua also rarely laughed, "Isn't this fucking irony?"

"It's really not..." He Zhongrui scratched his head and said, "You don't know, I sent both of them the workload of our 12-hour shift, and then... Li Zheng is always inexplicable by himself. , finish the work of the two of them together, and then the rest of their time..."

As He Zhongrui spoke, he swallowed and raised his head, "The rest of the time, I'm all showing off... I'm all studying."

Shen Tinglan stared suddenly: "What did you just say?"

He Zhongrui was startled.

This is a private chat, he has already scolded the dog couple.

But after all, this is a meeting.

One of them is the leader's precious daughter...

Still don't dismantle it face to face.

He Zhongrui had no choice but to falter and say: "Show me...that is, to show while learning, to show and learn, to learn to show..."

Chen Hongbing asked with a smile: "Why, you can't speak well after being hit by a high school student?"

"Hmm..." He Zhongrui is an honest man. After thinking about it, he nodded heavily, "That's it, Director."

"What?"

"Being hit by a high school student, I can't speak properly."

"Haha." Zhou Chenglong laughed first, "You have a day too!"

"..." Chen Hongbing was also a little confused, and hurriedly asked, "Then what exactly are they learning?"

"Algorithms for fault analysis, artificial intelligence neural networks, etc... I could understand them for the first half of the day, but I couldn't understand them after I fell asleep... Now I can't even understand what they say..." He Zhongrui had a bitter face Said, "It's just that I have worked hard to finish my master's degree in two or three years, and then others have finished it in two hours..."

"This sounds interesting..." Zhao Zhenhua rubbed his stubble and sighed, "Now these high school students are too motivated. After analyzing the data for half a day, they know how to take the initiative to find ways to make breakthroughs in work."

"But...the work in this area is not a matter of a week or two. Didn't the Eleventh Institute struggle for several years to make it like this?" Chen Hongbing asked, "They learn from scratch, not necessarily in a year. what happened?"

"Hey... Who didn't think so at first..." He Zhongrui turned to Zhou Chenglong and said, "You have more contact with the Eleventh Institute. Have they mentioned these two?"

"Eleventh...have you mentioned it...wait...it's them???" Zhou Chenglong stared, almost jumping up in fright, "So it's them!"

"Why are you so surprised today..." Chen Hongbing snorted and said, "Is it because you still have too much energy and are not saturated enough?"

"No, no, no..." Zhou Chenglong said with gestures and spouts, "I met someone from the eleventh institute that day, and he told me that there are too many resources for one department, and even a PhD in machine learning is a two-two trick... I didn't understand at the time, and he left..."

"..." This time Chen Hongbing couldn't ask any more questions.

Shen Tinglan next to her opened her mouth.

The people in each group didn't know how to talk anymore.

Zhao Zhenhua, on the other hand, was a little more prudent, thought for a while and said, "Go and ask the comrades in the [-]th Institute if the work done by these two interns has any practical significance in promoting the current zeroing. If so, we will find a way to cooperate."

As soon as these words came out, He Zhongrui was stunned.

It is reasonable to say that they failed in the test group and were transferred back.

It's too exaggerated for us to cooperate with them dignifiedly, right?

"Why are you so surprised?" Chen Hongbing sighed, "I can only think of arranging them to join the technical team, or Secretary Zhao, because he has a high vision."

"Not to mention." Zhao Zhenhua pursed his lips, "It's just that I have worked two years longer than you and have seen too many things about Qu Cai. Let them play to the fullest first, and go back to the test group if they can't."

Next, after the reports of each group were completed, Zhou Chenglong was left alone, and continued to talk with Zhao Zhenhua, Chen Hongbing and Shen Tinglan about the unfinished things just now.

At that time, Zhao Zhenhua questioned that only 60% of the fault model in front of him met the review, and it might be difficult to pass.
