Door-to-door dragon son-in-law

Apart from Wu Feiyan, the only other members of the Poqing Society who could pose a real threat to Ye Chen were probably these three elders.

Once the facial features of the three elders were determined, Ye Chen had a great deal of initiative. He didn't dare to take the initiative to attack, but at least he could avoid the three of them.

Lin Wan'er also breathed a sigh of relief for Ye Chen. She felt that with the AI ​​model, the ground network, and the facial features of Wu Feiyan and the three elders, Ye Chen's safety would be greatly guaranteed.

She has been hiding from Wu Feiyan for more than three hundred years, and her obsession with revenge has become weaker and weaker. If she were asked to choose, she would rather Ye Chen and Wu Feiyan keep out of each other's way. In this way, she would not have to worry about Ye Chen being in danger one day.

During the time she had known and spent time with Ye Chen, she had developed a strong sense of dependence on him. Putting aside the fact that they had saved each other's lives, the feeling of having no secrets from each other and of absolute trust was something she had not experienced in hundreds of years. The more this was the case, the more she cherished the present.

So, while Ye Chen was on the phone with Li Yalin, she said, "Brother Ye Chen, if we only know the appearance of Wu Feiyan and the three elders, we may not be able to rest assured. If they are in disguise, our early warning mechanism may fail."

Ye Chen said: "There shouldn't be any good way to do this, right?"

Lin Wan'er said quickly: "Inspector Li, can Ai learn how to judge a person's identity by his expression, gait, habitual posture and small movements? I think everyone's walking posture and habits must be different if analyzed carefully. Many people can disguise themselves and change their facial features, but it is difficult to abandon their behavioral habits all the time. If Ai can determine whether two people are the same person through their behavioral habits, then Brother Ye Chen's safety will be more guaranteed!"

Li Yalin on the other end of the phone pondered for a moment and said, "Ms. Lin's idea is not impossible to realize. As you said, everyone's behavior habits are different. We can definitely judge it through careful analysis. However, we humans are intelligent creatures with logical thinking and recognition abilities. Humans can easily complete this kind of recognition work, but AI requires a lot of learning. I can try to train it, but as for how to train it, I may need to think about it carefully."

Lin Wan'er's intelligent and kind eyes turned up and down, and then she said, "Inspector Li, I have an idea. I don't know if it is mature or not. Would you like to listen to it?"

Li Yalin said: "Ms. Lin, please speak."

Lin Wan'er said, "You can first ask the technicians to write a program to let AI analyze the surveillance videos of the data center. Through these surveillance videos and the staff in the surveillance videos, it can master how to calibrate the complete and accurate body contours of the moving human body, so that it can clearly distinguish the movement trajectory of each finger. Then let Ai carefully analyze the movement trajectories of all contours, and based on its facial recognition capabilities, deepen its understanding of the behavioral habits of the same person. After it has a clear understanding of the behavioral habits of everyone in the data center, let all staff members wear masks or cartoon masks to work normally, and let Ai match these people one by one based on their body behaviors, and see how accurate its analysis is."

Then, Lin Wan'er continued, "The accuracy rate at the beginning should not be too high. This requires our technicians to continuously optimize the code and logic, and at the same time optimize the capture methods and strive to increase the success rate to more than 95%. If it can achieve 95% recognition accuracy in the data center, we will expand the sample and choose a seat at the airport in Osu City, let it learn the behavior habits of thousands of people, mix one of our people in it, and let Ai find our people from these thousands of people to see how high the accuracy rate is. If it can reach more than 95%, there will be basically no problem. Of course, if we can give it more samples, it will be better. The more samples it learns, the richer the experience it accumulates, and the more effective the algorithm will be. If it can develop a keen eye and look at the back of a person walking, it can compare that this person is someone in the database, then it will be perfect."

Li Yalin was silent for a long time, and then he couldn't help asking: "Ms. Lin is studying computer science?"

Lin Wan'er said: "No, I studied archaeology..."

"Archaeology..." Li Yalin sighed and said sincerely, "Ms. Lin, how about I recommend you to study criminology at UCI in the United States? The criminology there is the best in the United States, and I feel that you are born to do this."

When Lin Wan'er heard what Li Yalin said about the school and major, she smiled meaningfully and said, "Inspector Li, you're too kind. I don't want to deal with all kinds of sinister and cunning criminals every day. Archaeology is easier."

Li Yalin said: "It's a pity that Miss Lin didn't join the police force. This industry is most in need of talents like you."

However, he also knew that Lin Wan'er's identity was mysterious and her background must be very important. He certainly could not persuade her, so he did not continue to say anything more about this issue, but simply said: "The method Miss Lin just mentioned should be very reliable. I will arrange for the technicians to try it hard. If it works, it will be of great help to the criminal investigation of the global police."

Li Yalin added: "However, this requires too much computing power and is too expensive. It is estimated that it will be difficult to popularize. However, we have sufficient computing power, so it will definitely be no problem to realize monitoring and early warning of a certain group of people."

Lin Wan'er said, "The speed at which computers have improved over the years can be described as the Big Bang of the universe. Perhaps the computing power problem will be solved in a few years."

"That makes sense." Li Yalin said with a smile, "I won't worry about my colleagues around the world. I believe that it won't be long before the computing power they can allocate will increase exponentially."

Then, he said, "Ms. Lin, Mr. Ye, if there is nothing else, I will hurry up and implement Miss Lin's idea and put it into use as quickly as possible!"

Ye Chen looked at Lin Wan'er and gave her a thumbs up, then said to Li Yalin: "Okay, Inspector Li, you go ahead and we'll contact you if we have anything else."

After hanging up the phone, Ye Chen couldn't help but ask Lin Wan'er: "Ms. Lin, the university and major that Inspector Li is going to recommend you to study, you must have already studied it, right?"

Lin Wan'er has lived for so many years and has obtained countless degrees. It is not surprising that she would study criminology when she has nothing to do.

When Lin Wan'er heard Ye Chen's question, she smiled and said, "I have studied in school, but not in the major."

After that, Lin Wan'er explained in detail: "The UCI that Inspector Li mentioned is the University of California, Irvine. The predecessor of the University of California was called California College. I was a student in the first class of California College and also the first Chinese student."

Ye Chen nodded as if nothing had happened, and said with a smile: "I guessed that you must have some connection with this school."

After that, Ye Chen asked her: "By the way, what year did you study at that California College?"

Lin Wan'er thought for a long time and said uncertainly, "It's been a while, and I don't remember it very clearly, but it was before the Civil War, because I left North America after the Civil War broke out."

Then she said hesitantly: "It should be 1854 or 1855..."

Ye Chen couldn't help coughing twice and said awkwardly: "Ahem... I knew this would happen a long time ago, but I didn't expect it to be this far away..."

Lin Wan'er smiled and said, "My lord, although it seems like a long time ago, even at that time, I was already over 200 years old. It was also around that time that many state universities were established in the United States. I was really bored, so I applied to some schools to study. Since my appearance hadn't changed, I didn't dare to study in college for too long. I could only finish the courses as quickly as possible, and then move to the next place and find the next university. I just regarded it as a pastime on the road to escape."

Then, Lin Wan'er said, "By the way, there is a group photo of the first batch of students and teachers in the historical archives of this school. I am in it. However, the photo is too old and the clarity is not good enough. I guess you won't be able to recognize me after seeing it."

Ye Chen searched the university's website out of curiosity, and found a group photo of the earliest students in the website's history. The photo from more than a hundred years ago had already turned blurry and yellow, but Ye Chen still found Lin Wan'er among the many men dressed in Western style. Lin Wan'er in the photo looked quite thin, and the overall tone of the photo was yellowish, making her look a bit like an Indian girl.

Ye Chen was able to recognize Lin Wan'er because Lin Wan'er said she was here. Otherwise, he would not be able to tell anything just by looking at the photo.

After carefully looking at the photo, Ye Chen asked her in surprise: "It seems that there are only a few female students in this school."

"That's right." Lin Wan'er said, "In that era, men and women were still very unequal. Women's social status was not very high, and they were not valued by their families. Only a few could go to university."

As she spoke, Lin Wan'er came over to take a look, then pointed at one of the middle-aged white men and said to Ye Chen, "This was a very prestigious professor at the school at the time, and one of the co-founders of the university. But in fact, he was an orphan that I adopted and raised in England. When I brought him from England to North America, my public identity became his adopted daughter. When I later went to Japan, it was he who wrote the recommendation letter for me to study in Japan."

Ye Chen couldn't help but sigh: "Miss Lin's life is so colorful."

Lin Wan'er smiled and said, "Young Master is destined to achieve immortality in the future. By then, you will be able to experience that kind of colorful life."

Ye Chen shook his head and said, "Society is progressing too fast. Even if I become immortal and don't have to hide from Wu Feiyan like Miss Lin did, I will have to try my best to hide from the whole world. It is no longer possible to travel around the world with different identities and integrate into the lives of these places like Miss Lin did."
