When I am reborn, I just want to be a top student

Chapter 185 New direction, switching to artificial intelligence

After Wang Donglai pointed out the direction, Xue Tao and others started taking action.

However, as soon as they got started, a few people realized that it was far more difficult than they imagined.

However, a few people didn't say anything, but gritted their teeth and started to study. They couldn't rely on Wang Donglai for everything, then they would really become a drag.

In fact, Wang Donglai could sense the thoughts of several people. He didn't say anything, but he was extremely satisfied in his heart.

When people get along with each other, if one party is completely dependent on the other party, no matter how good the relationship is, it will not last.

Even parents and children must learn to let go at a certain stage.

Putting aside the matters of Xue Tao and others, Wang Donglai came to Xu Songyao's office.

This time, in Xu Songyao's office, Wang Donglai met Director Ding of Institute 11 whom he had met before.

As soon as they met, Director Ding was all smiles. He took the initiative to hold Wang Donglai's hand and said, "Professor Wang, you are really young and promising. I have also heard about your feats at the Princeton Academic Exchange Conference." , that is no less than Guan Erye warming wine and beheading Hua Xiong, it is really enviable!"

"Speaking of it, I regret it so much now. If I had known, I should have made up my mind to recruit people when I met Professor Wang. I missed such an outstanding talent in front of me. It really hurts my heart."

As he spoke, Director Ding took out a document from his briefcase and handed it to Wang Donglai.

Xu Songyao spoke at this time and said with a smile: "Director Ding's words are really kind. Who doesn't know that the elite soldiers and generals of the 11th institute are all elites from top universities. They come from all over the world to help. This is what they should do. After all, it is our duty to serve the country.”

Director Ding laughed and waved his hand, as if he did not understand the meaning of Wang Donglai's words, and said with a smile: "I came here specifically to thank Professor Wang. Last time, with the help of Professor Wang, our The project has made great progress, and the specific situation cannot be disclosed. I can only say that the experimental results are excellent, and it has also received awards from above. I came here specifically to thank Professor Wang."

Wang Donglai acted extremely calmly in the face of Director Ding's enthusiasm. He first glanced at Xu Songyao and found that Xu Songyao didn't say anything. There was also a look of pride on his face. He knew what he was thinking.

It's not much, but the entire reward money is not only given to Wang Donglai, but also distributed to other people. If Wang Donglai's achievements were not obvious to everyone and greatly promoted the completion speed of the project, I am afraid the money would be even less.

Wang Donglai can also speak in scenes, and there is no sense of violation in what he said at this time.

In the following time, I quickly started chatting with Xu Songyao and did not neglect Wang Donglai, giving people a feeling of spring breeze.

Two hundred thousand.

As expected of a leader, Director Ding was extremely enthusiastic as soon as they met, far exceeding his attitude last time.

"The principal is right. It's an honor for me to be able to contribute a little bit. Director Ding, please stop giving me a high hat."

"Anyway, this incident is all thanks to Professor Wang. If it weren't for Professor Wang, I don't know when the experiment will be completed, and other laboratories may be the first to do it. These compliments of mine are all from my heart. heart."

In addition, he invited foreign aid halfway, so this share is not small.

"Director Ding, you're welcome. You're busy, so you shouldn't ask for help again this time, right?"

"I heard that you were in No. 11, and someone was targeting you? Did something happen?"

"What's more, the whole experiment was done by everyone together, and I only played an insignificant role."

After Director Ding was sent away, Xu Songyao and Wang Donglai's expressions became calmer, and they did not look like they had a happy conversation with Director Ding before.

The top part of the document is the official commendation document for the project breakthrough of 11 institutes, while the bottom part is the reward for Wang Donglai.

"Academician Xu has a good vision. He saw Professor Wang's extraordinary qualities early on. This vision is admirable!"

Director Ding is also a person who is involved in official circles. He attracts people and treats them, and has a very high emotional intelligence.

"It's a pity that ordinary people like us don't have Professor Wang's ability. We can only be spectators and watch Professor Wang achieve greater glory and achieve great results."

Xu Songyao asked with interest.

"I just happened to come across some bad things in their institute." If Xu Songyao hadn't said it, he would have almost forgotten Zhong Wei from Institute 11.

Nodding, Xu Songyao had obviously experienced similar things and was not surprised.

"Wherever there are people, there are rivers and lakes. As long as there are people and interests, there will naturally be many such things, and you will see more and more of them in the future."

"It's just that I still hope that you can maintain a good attitude and don't let these things affect you. Your strength lies in academic research. Don't sacrifice yourself for the bottom. Don't forget the foundation of your life."

Every time he saw Wang Donglai, Xu Songyao felt a touch of emotion, feeling that time had passed and he was almost sixty years old.

Therefore, he subconsciously told Wang Donglai these life principles and personal experiences.

Wang Donglai was not impatient, but nodded and agreed.

"Institute 11 is a confidential unit. The project you helped complete is also a confidential project and is not suitable for disclosure, so I won't congratulate you in a big way. But don't worry, everything you do can be seen above."

"This money is not much, but it means something different. You are still young and not short of money. If you have the opportunity in the future, you can take on more projects like this. It will be of great benefit to your future."

Xu Songyao sat back on the chair and said to Wang Donglai in a warm voice.

But when Wang Donglai heard this, he felt something was wrong.

As soon as he rolled his eyes, he said loudly: "Principal, there are no outsiders here. Do you have any projects you want me to do?"

Although it was a question, Wang Donglai knew that his guess was correct and his tone was affirmative.

"I knew I couldn't hide it from you, kid. I do have a project here, and it's similar to what happened last time. You happen to be developing in the field of artificial intelligence, right? It's just enough for you to see and learn."

Seeing that Wang Donglai had guessed his purpose, Xu Songyao stopped hiding it and started to explain directly.

"This is a project book. You can take it and have a look. This time it is an idea proposed by the First Affiliated Hospital to our school. I think it is quite interesting, so I thought of you. It is algorithmic reconstruction of medical images, and you know computers. , and you are talented in mathematics, so I thought of you, what do you think?"

After hearing Xu Songyao's explanation, Wang Donglai naturally didn't hesitate at all and said directly: "Since the principal can think of me immediately, I will definitely not disappoint the principal. I will take this project." With that, Wang Donglai said I opened the project book and started looking at it.

The content inside is actually not difficult to understand. I just want to develop a set of algorithms to make medical images more accurate.

To put it more simply, it means developing a set of algorithms to make the results of B-ultrasound and CT scans clearer and more accurate.

Don't think that these things have nothing to do with algorithms. Whatever the X-ray hits will be revealed.

Even the cameras on mobile phones have algorithms. Why Apple’s cameras are so good? I have to say that algorithms also play a certain role in it.

Major domestic manufacturers have taken a different approach. As long as you take a photo, you can directly bring in your own beauty. This is a built-in algorithm, which is completely incomprehensible to the human body.

"I have also read the topic of this project. If you have an idea, you can also invest directly. Didn't you tell me about industry, academia and research? This is an opportunity. Do you want to do it?" Xu Songyao at this time, He asked again.

Wang Donglai was a little moved and a little surprised. He didn't expect that he just said it to Xu Songyao, and he really remembered it in his heart.

Although this project seems difficult, it is actually divided into two types: difficult and easy. The difficult is to completely rebuild and greatly improve the accuracy. The simple is that it does not necessarily need to be so advanced, as long as it is more advanced than the first. Just a little will do.

It can be said that it has great flexibility.

With these thoughts flashing through his mind, Wang Donglai said: "Principal, I voted for this project! Since I said industry, academia and research, I mean it."

Wang Dong spoke very seriously and firmly.

In Wang Donglai's eyes, in just a few seconds, he figured out how to utilize and develop this project.

He has no doubt about his own strength, and now he has this opportunity to prove it, which is also a good thing for him.

"Okay, just be confident. If you have any questions, come to me at any time. If I'm outside, just contact the school office. I've already said hello in advance."

Xu Songyao did not hide his appreciation and support at all, and directly encouraged him.

"Well, thank you principal for your support!" Wang Donglai nodded and wrote.

……

With the project book in hand, Wang Donglai returned to his office.

As a professor at Tangdu Jiaotong University, not everyone has a separate office, most of them are in public offices.

But Wang Donglai is different. He has a large independent office.

Sitting in the office, Wang Donglai flipped through the project book.

The reason why the First Affiliated Hospital proposed this topic is actually because there is a lot of room for improvement in medical imaging with existing instruments.

The simplest X-ray film has the simplest technology and only requires X-ray detection.

CT still uses X-rays, but it uses a new imaging method to capture images from different angles. It uses a large number of projection images taken from different angles, and then uses mathematical algorithms to calculate a cross-sectional image, so that it can Seeing the image of each section is called computed tomography.

Ultrasound imaging achieves imaging by emitting and receiving ultrasound waves. Compared with X-rays and CT, ultrasound waves do not damage the human body and are often used for prenatal check-ups. Although the penetrating power is not as good as X-rays, it is suitable for scanning superficial tissues. Although the images are not clear enough , but the time resolution is high, and it can measure functional parameters such as blood flow velocity, which is of great significance for the diagnosis of vascular diseases.

Finally, there is MRI, which is nuclear resonance imaging. The image quality is good, it can produce three-dimensional cross-sectional images, there is no radiation, and it is very flexible. By designing different sequences, various types of images can be produced.

As for the principle, it is based on the nuclear magnetic resonance phenomenon of atomic nuclei. Taking hydrogen nuclei as an example, when placed in a strong magnetic field, they will split into two states: high energy state and low energy state. At this time, a radio frequency pulse will be applied, and many atomic nuclei will be separated from each other. The low-energy state transitions to a high-energy state. After the pulse ends, the atomic nuclei will gradually return to their original low-energy state and release electromagnetic signals. Here comes the most critical point. Some atomic nuclei (such as hydrogen atoms in water) recover very slowly. Some nuclei (such as hydrogen atoms in fat) recover quickly, so they can produce contrasting signals that can be used for imaging.

After briefly reading these principles, Wang Donglai understood something in his heart.

As long as it is measured, parameters will be inconsistent due to various external factors, and errors will occur.

Therefore, the purpose of this project is to use deep learning to restructure an algorithm for constructing internal images, thereby improving accuracy and adding technical support to doctors’ diagnosis.

The reason why this project is related to artificial intelligence is because deep learning is a part of machine learning, and machine learning is a part of artificial intelligence.

Coupled with Wang Donglai's previous computer prowess, Xu Songyao handed over this project to Wang Donglai.

It was successful, Xu Songyao was happy and proud of Wang Donglai.

Even if it fails, Wang Donglai will also know the difficulty of artificial intelligence, and he may be discouraged. This is also a good thing for Xu Songyao, who wants to persuade Wang Donglai to return to the field of number theory.

In fact, Wang Donglai had already figured this out, but he didn't care.

Medical image reconstruction may be difficult for others, but it is not a big problem for him.

Because after he stopped studying mathematics, he focused more on computers and physics, which led to a rapid increase in experience in these two subjects.

With the experience of turning on [Brain Overclocking] last time, he now has the confidence to complete this project.

Moreover, he invested in this project himself and produced results, which are his own patents, and he does not have to worry about making wedding dresses for others.

The reason why he went around in circles was because he still needed the necessary data and information from the First Affiliated Hospital. Without the Tangdu Jiaotong University brand, it would not be that easy to get these data.

Soon, after reading the project book, Wang Donglai was moved in his mind and prepared to apply for outstanding youth with this project.

But after thinking about it, even if I apply for it, it will probably be in vain.

Because there is one condition for applying for Outstanding Youth, that is, he must be independent, have no contact with foreign countries, and have worked in a university or research institute for nine months or more. He has not had a full month yet.

In addition, by the time the application is submitted, I'm afraid he would have completed the project long ago.

"This must be the trouble of being too good!" Wang Donglai shook his head and chuckled, putting the project book in his hand on the table.
