Beauty is the eternal pursuit of mankind.
Fine wine, good food, beautiful women, beauty, sweet dreams, good talks...
These words with the word "beautiful" contain good meanings.
Among them, beauties have the widest audience and are the most attractive.
From the four beauties in ancient times, to various class beauties, department beauties, and school beauties in modern society, to the entertainment industry, which is often called the most beautiful in thousands of years.
Once these words appear, they always attract the attention of many people.
When Shi Hang from the Yao class asked him to show off his abilities, Wang Donglai thought about it quickly in his mind.
Finally, I chose the small field of beauty.
Currently, there are many beauty software and various beauty cameras on the market.
For example, Meitu Xiuxiu.
However, Wang Donglai, who has experienced the baptism of various beauty software and filters in the future, simply does not like the beauty products of this era.
Not only that, he also wants to use his own technology to truly restructure a set of algorithms through artificial intelligence technology to create better beauty products.
Just copying it, the quality is really too low.
The beauty program is moderately difficult and has a large audience. Women will not dislike it.
The commercial field has broad application prospects.
It’s hard to say that Douyin was so successful in its previous life because of its beauty factor.
In Wang Donglai’s vision, Five Days could only produce a rough framework of beauty products.
If you want better subsequent results, you need to invest more data resources.
For example, more photos of beautiful women.
However, he has completed a rough framework, and the preliminary results are enough to beat the beauty products currently on the market.
After all, these beauty products nowadays are nothing more than whitening, skin resurfacing, face slimming, etc.
It can be said that the technical content is there, but it is not high.
Wang Donglai wants to create beauty products, but naturally it cannot be that simple.
They all use artificial intelligence technology, and the expected results are definitely much higher than the products on the market.
In the simplest terms, using this beauty program not only achieves a beautifying effect, but the effect is also very natural and in line with different personal styles.
The stereotyped snake-like faces and cold-skinned faces in later generations are really nothing new.
And this is what Wang Donglai wants to do using artificial intelligence technology.
Thousands of people have different faces, and everyone’s final beauty effect is different.
In China, there is a more authoritative saying about beauty.
Three courts and five eyes, four high and three low.
The "three courts" in "three courts and five eyes" refers to the length ratio of the face. The length of the face is divided into three equal parts, from the forehead hairline to the brow bone, from the brow bone to the bottom of the nose, and from the bottom of the nose to The chin each accounts for one-third of the face length.
The 'five eyes' refers to the width ratio of the face. Taking the length of the eye as the unit, the width of the face is divided into five equal parts. From the left hairline to the right hairline, it is five Eye shape.
Of course, this is just a widely circulated statement.
Wang Donglai considered these things when he wrote the algorithm.
A beauty software that meets the taste of Chinese people must be recognized by both female users and liked by male users.
"Huh!"
Before starting, Wang Donglai went through this information in his mind and activated the [Brain Overclocking] skill.
As the wonderful feeling emerged, Wang Donglai felt that his brain was clear for a while, as if thousands of inspirations were born, and he could not wait to take action immediately to turn the inspiration in his mind into reality.
"Crackling..."
Ten fingers began to tap on the keyboard quickly.
At the same time, I saw characters jumping out one by one on the screen.
……
A flash.
It’s the third day.
Chinese Academy of Sciences, Supercomputing Center.
Wang Donglai was also a little surprised when he received the news that Yao Qizhi had applied for permission to use the Supercomputing Center of the Chinese Academy of Sciences.
Just thinking about it for a moment, Wang Donglai understood.
As the winner of the Turing Award, Wudaokou has put so much effort into recruiting Yao Qizhi to the school, so he will naturally give his full support.
Wudaokou also has a supercomputer, but its computing power is not strong.
Wang Donglai finally spoke, and Yao Qizhi naturally did not fool Wudaokou's supercomputer.
If Wang Donglai wanted to use Wudaokou's supercomputer, he wouldn't have to tell himself that.
So, after agreeing to Wang Donglai, Yao Qizhi did not delay. After taking out his mobile phone and making a call, he put the matter down.
The next thing is very simple.
The Supercomputing Center of the Chinese Academy of Sciences directly allocated four hours of time to Wang Donglai.
The reason why we chose the Supercomputing Center of the Chinese Academy of Sciences is that during this time, only the Supercomputing Center of the Chinese Academy of Sciences can spare the time.
The tasks of supercomputing centers are often relatively ambitious, such as simulating the 14 billion-year evolution of the universe, or completing projects such as a fingerprint identification system.
Once started, it cannot be interrupted.
It often takes several months or hundreds of days to complete.
Although the capital is a core place, there are many units with supercomputing, but the computing power needs to be large, and it cannot be a confidential unit, and it can squeeze out time.
Put these requirements together and the number will decrease rapidly.
Therefore, in the end, only the Supercomputing Center of the Chinese Academy of Sciences was the most suitable.
"How is it? How is the Supercomputing Center of the Chinese Academy of Sciences? Can it meet your requirements?"
Yao Qizhi asked Wang Donglai.
Wang Donglai nodded and said with thanks: "Thank you, Academician Yao, for your efforts. Being able to apply for the Supercomputing Center of the Chinese Academy of Sciences is enough for me."
Yao Qizhi nodded, Asked: "By this time, you should be able to tell me what you want to use the supercomputer for, right?"
As he said that, he also looked at what Wang Donglai was carrying.
At this time, Wang Donglai naturally did not hide anything, so he said aloud: "Academician Yao, it's not that I kept this secret deliberately, it's just that you didn't ask before."
"Yao's class. Don’t students want to see what products I can make using artificial intelligence technology? ”
“I have written a small program in the past two days. I will run it through a supercomputer later, absorb the collected data information, and conduct some deep learning, and it will be almost done.”
Wang Donglai spoke in an understatement, but Yao Qizhi's face showed a bit of shock and more of curiosity.
As a professional technician, Yao Qizhi thought quickly in his mind based on Wang Donglai's two sentences and asked: "Oh, so to speak, you have completed the general program structure, and you will be ready to use the computing power of the supercomputer later. , let this program learn deeply?"
Wang Donglai nodded and admitted.
"Hiss..."
Yao Qizhi took a breath and looked at Wang Donglai with eyes full of surprise and scrutiny.
After a while, I regained my composure and asked: "Are you so good at neural networks and deep learning?"
"Well, it's actually not difficult!" Wang Donglai replied naturally.
“…”
Yao Qizhi was speechless.
Is it difficult? He, a Turing Award winner, still doesn’t know. After a moment of silence, Yao Qizhi asked aloud: "Can I master mathematics and be able to play with computers?"
Wang Donglai thought for a while and said: "Well, it should be okay. After all, computers are still a combination of 0 and 1."
"Okay."
Yao Qizhi nodded, secretly in his heart Thinking about it, should I adjust my emphasis on mathematics?
While the two were chatting.
A middle-aged man wearing glasses walked out of the supercomputing center, followed by several younger researchers.
"Dean Yao, hello."
The middle-aged man stepped forward quickly, took the initiative to shake hands with Yao Qizhi, and said very politely, with a bit of excitement in his tone.
"Hello, Director Chi, let me introduce to you. This is Professor Wang Donglai. It is also because Professor Wang needs to use supercomputer this time."
"Donglai "This is Director Chi from the Supercomputing Center."
Yao Qizhi held Director Chi's hand with a smile on his face. After saying hello, he took the initiative to introduce the two parties to each other.
"Hello, Professor Wang!"
"Hello, Director Chi!"
Wang Donglai and Director Chi greeted each other at the same time.
"I have been famous for Professor Wang for a long time. He is said to be young and promising. Now I see that he is completely humble. He is completely a young talent."
Director Chi praised with a smile. Looking at Wang Donglai, his tone was sincere.
Wang Donglai said with a smile: "Director Chi, thank you for the award."
After some polite greetings, under the leadership of Director Chi, everyone came to the supercomputing center.
“In 2007, we introduced the IBM CellBE computing cluster. Two years later, we introduced the exascale domestic product ‘Shenteng 7000’ supercomputer. After that, with the rapid development of domestic supercomputing technology , I can be proud to say that the computing power of our supercomputing center of the Chinese Academy of Sciences is also in the first echelon among universities and research units across the country."
Director Chi introduced it to Wang Donglai and Yao Qizhi with pride. about the situation of the supercomputing center.
Soon, after the introduction, Director Chi asked about Wang Donglai.
"Professor Wang, what research project are you planning to conduct? Is four hours enough?"
The reason why Director Chi asked this is because domestic supercomputing is still in the development stage and the computing power is far from sufficient.
The successive establishment of the National Supercomputing Center has gradually hatched a computing power market in the country.
Scientific research institutes and Chinese universities have gradually reduced the scale of self-built supercomputers and increased the procurement of external supercomputer resources.
The Supercomputing Center of the Chinese Academy of Sciences is an exception.
It has powerful computing power and can almost meet the needs of three types of supercomputing projects: cutting-edge supercomputing, general supercomputing and industry supercomputing.
Cutting-edge supercomputing is mainly aimed at national-level scientific research projects, such as astronomical phenomena, earthquakes and other projects, while general supercomputing and industry supercomputing are more detailed.
At this time, when Director Chi asked this question, it was just a normal inquiry.
Wang Donglai had known about these in advance, so he said: "A general-purpose supercomputer will do. I wrote a program that needs to be run on the supercomputer. Four hours should be enough."
Director Chi was a little surprised. Said: "It turns out to be running a program. I thought that Professor Wang was going to use supercomputing to prove mathematical problems and verify his own ideas. I didn't expect Professor Wang to have such accomplishments in computers. He is indeed young and promising. Ah!”
After the polite words, Director Chi continued: "Professor Wang, you may not be aware that to run a program on a supercomputer, you don't just have to put it directly on it. You also need to compile, tune, and integrate the source code in the Linux command line window. If the procedure is complex, more complex adaptation transplantation will be required.”
“Professor Wang, I didn’t know you had it. Didn't you do the preparations well? If you haven't done it, there is still some time, and if the procedure is not complicated, you should be able to make it in time."
Hearing what Director Chi said, Wang Donglai's expression did not change and he said. : "Thank you for your concern, Director Chi. I have prepared these before."
"Well, that's good!" Director Chi nodded.
Soon.
It's the appointed time.
Wang Donglai did not borrow the help of others and started to operate it himself.
China started late in the field of supercomputing, but is catching up quickly.
In 2013, the National University of Science and Technology developed the Tianhe-2 supercomputer system, with a peak computing speed of 549 petaflops per second and a sustained computing speed of 339 petaflops per second, with extremely superior performance.
At the Supercomputing Center of the Chinese Academy of Sciences, the Tianhe-2 supercomputer system was introduced.
At this time, the supercomputer started to run.
Wang Donglai and others can also take a break and wait with peace of mind for the supercomputer to give out the results.
At this time, Director Chi stood up with a smile and said: "Professor Wang, I have always heard that your achievements in the field of mathematics have filled several blank records in China, and have greatly contributed to domestic achievements internationally. If you have a long face, it is not an exaggeration to say that you will bring honor to the country."
To show your courtesy for nothing is to be either a traitor or a thief!
From the first meeting, Wang Donglai had a feeling that Director Chi seemed to be paying close attention to him and showing goodwill.
At this time, when he heard Director Chi praising himself so much, Wang Donglai was moved in his heart and said aloud: "Director Chi, thank you for your praise. My achievements are nothing compared to those of my predecessors. Moreover, our country is a big and powerful country. With the As the country recovers, there will be more and more such things."
Director Chi laughed and said, "Professor Wang, you are too modest."
"Actually,. I have a merciless request. I want Professor Wang to Do me a favor, I don’t know if I can.”
“Originally, I shouldn’t have raised it at this time, but this problem has been bothering us for a long time, and it is also related to supercomputing. Once a problem occurs, it will have a huge impact. "Professor Wang happens to be here, so I took the liberty to bring it up."
"I know that Professor Wang's time is more important and he has a lot of things on his hands. If he really can't spare the time, it doesn't matter." .”
At this point, Director Chi finally revealed his true purpose.
When Director Chi said this, neither Yao Qizhi nor Wang Donglai were too surprised.
Yao Qizhi is because he has seen this kind of thing too much.
Why mathematics is said to be the mother of natural sciences is because mathematics plays an extremely important role in many fields.
Having a top mathematician here can make many research topics easier.
Wang Donglai is actually no stranger to Director Chi's requests. He has received many requests since he became famous.
He had done this several times at Jiaotong University in Tangdu.
As for some other schools and research institutes, they have no friendship and it is difficult to find Wang Dong.
"Director Chi, you might as well talk about it and let me see what the problem is, so that I can have an idea." Wang Donglai did not agree in a big way, but said so with some room for it.
Hearing what Wang Donglai said, Director Chi immediately smiled, looked around, and said: "Professor Wang must also know that the larger the equipment, the greater the possibility of failure. ”
"Especially supercomputing, which has excellent performance and powerful computing power, naturally requires a large number of processors to work. Therefore, there is an ongoing issue here, which is to ensure the smooth operation of the processors without errors."
“Last year, the service time of our center reached 99.9%, and the equipment utilization rate reached more than 95%. It can be said that we have been operating at full capacity, so we cannot cause a failure because of a certain processor failure. The project cannot be completed in time."
“In this regard, we have also taken many measures to solve this problem and ensure the completion of computing tasks. However, as computing power becomes stronger and stronger, these previous measures must also keep pace with the times. ”
“Professor Wang, you are the national There are actually famous mathematicians who know a lot about computers. It just so happens that the center has built a control system. Can Professor Wang help check the mathematical model in it?"
When Director Chi finished speaking, Yao Qizhi’s His face looked a little ugly.
He is a Turing Award winner, but in the eyes of Director Chi, he can't even solve a supercomputer crash-proof control system, and has to ask Wang Dong to check the mathematical model.
Distrusting his ability is one of them.
The second thing is that Wang Donglai applied for the supercomputer by himself, but now that Director Chi is asking Wang Donglai, he seems to be bypassing him.
In this regard, Yao Qizhi didn't say anything, but was waiting for Wang Donglai's reaction.
If Wang Donglai is unwilling, he will speak out immediately to end this farce.
Just when Yao Qizhi was waiting for Wang Dong to react.
Wang Donglai looked calm, without any hesitation, and said confidently: "Is it such a simple thing? Leave it to me!"
As soon as he said this, Director Chi looked happy , the nearby researchers also looked curious and expectant.
It is impossible to say that no one would envy Wang Donglai, a genius in the field of mathematics, who won three top international awards in one go.
It's just that mathematics is different from other subjects. If you don't know it, you don't know it, so not many people doubt that Wang Donglai is a deceiver.
And because Wang Donglai was younger than many researchers present, everyone was even more curious and wanted to see Wang Donglai's demeanor. (End of this chapter)
