I really don't want to lie down and win

The next day,

Xu Mang came to his workplace,

To his relief, the double black hole event successfully detected gravitational waves. Of course, the author of the theory published it as a gravitational wave detection laboratory, and it was published on the cover of Nature, which caused quite a stir.

of course,

To Xu Mang, this was just a small episode, and now he needed to start solving the AI ​​for analyzing protein structures.

Currently,

Xu Mang's knowledge in the field of artificial intelligence has almost reached the proficient level, but first he needs to communicate with experts in biology, and then he logs on to Fuda's official website, and Xu Mang finds Director Tian of the Department of Biology.

"Hey?"

"Is it Director Tian of Fuda Biology Department?" Xu Mang said with a smile, "Guess who I am?"

Snapped!

was hung up.

Xu Mang: ￣￣?

what?

what's the situation?

The buddy was actually hung up.

Called again,

"Hey?"

"Director Tian...I'm Xu Mang." Xu Mang said seriously, "Then what... I have something to ask you. I'm going to study artificial intelligence that can analyze protein structures. I hope that through cooperation with Fuda's Department of Biology, involved in this field together.”

Hearing Xu Mang's words,

Director Tian was a little surprised, and at the same time had a bit of expectation. He had heard a little about the achievements of artificial intelligence in analyzing protein structures, but those were the specialties of Europeans and Americans.

"Xu..."

Director Tian didn't know how to address Xu Mang for a moment. He was no longer a professor at Fuda, so he shouldn't be able to be called Professor Xu, but he didn't even want to call him by his first name. It seemed a little disrespectful to others.

"hey-hey."

"Director Tian can just call me by my name." Xu Mang knew Director Tian's embarrassment at this time, and said silently: "I am no longer a professor at Fuda, so there is no need to call me Professor Xu."

"..."

"Cough cough!"

"Although you are no longer a professor at Fuda University, your influence is still there." Director Tian smiled and said, "Professor Xu...Thank you for your cooperation proposal. I think it is very good. This technology is currently used in Europe and the United States. It is very important, but there are very few in our Huaguo. I have found the computer department before, and I want to study AI to analyze protein structures together, but unfortunately..."

Xu Mang said: "We can't blame them for this. It involves many disciplines, such as cybernetics, biology, chaos theory, etc. In short, this is a complex interdisciplinary subject, and it is absolutely impossible to find someone from the computer department."

Director Tian was a little confused. Since so many issues were involved, could Xu Mang do it alone?

"Cough cough!"

"Professor Xu...Since so many aspects are involved, how many people do you have?" Director Tian asked, "You can't be alone, right?"

"Yup!"

"It's just me." Xu Mang said with a smile: "Don't worry, my wife's company has talents in this field, it's really not good... I'll find the scientific research personnel under my father-in-law's company and ask them to develop it with me That's it."

"What about creatures?"

"Biology?" Xu Mang was stunned for a moment, then said calmly, "Director Tian...I'm good at biology, and I graduated from high school."

Director Tian:? ? ?

Does he understand biology?

Are you kidding me?

"how?"

"Director Tian seems to have some disbelief in my words." Xu Mang said calmly, "Well...let me talk about my conceptual understanding of artificial intelligence in analyzing protein structures."

"First of all, I will choose a method similar to Google's, starting with a method called multiple sequence alignment, which first compares the sequence of a protein with similar sequences in the database, and finds out a chain that is not adjacent, but often Pairs of amino acids that occur in tandem."

"This shows that these two amino acids are close to each other in the folded protein, so we trained a neural network to obtain such pairings and predict the distance between the two paired amino acids in the folded protein," Xu Mang said.

Then,

Xu Mang added: "By comparing the prediction results with the accurately measured distances in the protein, this method can learn how to better predict the way the protein folds. A parallel neural network is responsible for predicting the continuous distance in the folded protein chain. The connection angle between amino acids."

At this time,

Director Tian was already shocked. He never expected that Xu Mang really understood biology and was very proficient.

"but..."

"I won't take this approach." Xu Mang smiled calmly: "These steps themselves cannot predict the structure, because the predicted distance and angle may not be realistic."

......

Chapter 7 Challenge! (2/3)

The second way?

Director Tian has heard of this AphaFod algorithm, which is basically the same as what Xu Mang described, but what is shocking is that Xu Mang really has a special understanding of artificial intelligence, especially in one of the most challenging problems in biology. , How to predict the three-dimensional structure of protein from the amino acid sequence, has a unique understanding.

he...

How is it possible to even understand biology?

He had never heard of a physicist who could master biology so well, so Xu Mang was probably the only one.

"Cough cough!"

"Professor Xu?" Director Tian asked curiously: "How did you learn biology? You're not a science student either...how can you learn biology? Don't tell me that you are all self-taught... .I don't believe that."

however,

The answer Xu Mang gave was even more nonsense.

"Then what... I have a special learning method called sleep learning." Xu Mang said seriously: "Whenever I fall asleep, many scientists in history will give me lessons, such as Charles Robert Dahl, So I taught me the knowledge of biology."
