Apart from Wu Feiyan, the only other people in Poqinghui who could really threaten Ye Chen were probably the three elders.

Once the facial features of the three elders were determined, Ye Chen would have great initiative. He didn't dare to take the initiative, but at least he could avoid 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 had been hiding from Wu Feiyan for more than three hundred years, and her obsession with revenge had become increasingly weak.

If she were to choose, she would rather hope that Ye Chen and Wu Feiyan would not interfere with each other, so that she would not have to worry about Ye Chen being in danger one day.

During the time she had known and gotten along with Ye Chen, she had already developed a strong sense of dependence on him. Putting aside the fact that the two had saved each other's lives, the feeling of having no secrets and absolute trust in each other was something she had not had for 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 features of Wu Feiyan and the three elders, we may not be able to rest assured. If they disguise themselves, our early warning mechanism may fail."

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

Lin Wan'er hurriedly said, "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, "Miss Lin's idea is not impossible to realize. As you said, everyone's behavior habits are different. Careful analysis can definitely determine it. 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. As for how to train it, I may have to think about it carefully."

Lin Wan'er's smart 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. Do you want to listen to it?"

Li Yalin said, "Miss Lin, please speak."

Lin Waner said: "You can first ask the technicians to write a program to let Ai analyze the surveillance videos of the data center. Let it master how to calibrate the complete and accurate body contours of the moving human body through these surveillance videos and the staff in the surveillance videos."

"It should be detailed enough to clearly distinguish the movement trajectory of each finger. Then let Ai carefully analyze the movement trajectories of all contours, and deepen its understanding of the behavioral habits of the same person based on its facial recognition capabilities. 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 to see how accurate her analysis is."

Then, Lin Wan'er said, "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, select a plane position 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 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, it can compare a person walking from the back and find that the 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, "Is Miss Lin studying computer science? "

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

"Archaeology..." Li Yalin sighed and said sincerely: "Miss 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 the school and major mentioned by Li Yalin, she smiled with a hint of deep meaning on her face and said with a smile: "Inspector Li, you are too kind. I don't want to deal with all kinds of insidious and cunning criminals every day. Archaeology is easier."

Li Yalin said: "It's a pity that Miss Lin didn't join the police. What this industry lacks most is talents like you."

However, he also knew that Lin Wan'er's identity was mysterious and her background must be very important. It was definitely not something he could persuade, so he didn't 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 also be of great help to the criminal investigation of police around the world. ”

Then, Li Yalin said: "However, this requires too much computing power and the cost is too high. It is estimated that it will be difficult to popularize. But our computing power is sufficient. If we want to realize the monitoring and early warning of a certain group of people, there will definitely be no problem. ”

Lin Wan'er said: "The speed of computer improvement in recent years is not an exaggeration to say that it is the Big Bang of the universe. Maybe the problem of computing power will be solved in a few years. ” JrNovels.com
