While Xia Yu took Luo Luo to have fun in the bamboo forest garden, Yang Yan and Mr. Dai were still sitting in the monitoring room, waiting quietly, hoping that good news would appear in the data fed back by the remote server!

Of course, the effectiveness of the "intelligent human recognition" system written by Yang Yan has actually been initially verified.

Before this, the "intelligent person recognition" system has provided two matching verifications and successfully found their relatives for two families looking for relatives!

However, after seeing the matching result, Yang Lin awkwardly told Yang Yan that the system matching result was correct, but it could not be considered a surprise, because these two groups of people were actually two of the three groups of "sponsors" arranged by the organizer.

After all, this is an official search event, and Yangcheng Radio and Television Station is also here to record the program on site. If no one finds his lost relative as he wishes after the event, the organizer will be embarrassed!

Therefore, the organizer arranged three groups of "sentences" in private. Of course, this cannot be regarded as a sentence, because they are all real cases found by the Social Welfare Foundation, and they are just re-showing the reunion of relatives that have happened in this square again!

"That Zhao Shang lost his memory because of an accident more than ten years ago. Later, he lived a wandering life in Yangcheng. The winter of the previous year, when the Civil Affairs Bureau distributed winter supplies to the social homeless people, he counted his information. It happened that his sister had come to Yangcheng to look for him every year for more than ten years. People from the Civil Affairs Bureau identified him and helped him find his family..." Yang Lin and Yang Yan and the others told the stories behind these "sentiments".

Although the two sets of matching results found are "support" and cannot be considered as meritorious service, everyone still recognized Yang Yan's system, and Yang Lin even praised it, saying that this system is indeed very good. In the monitoring room, people who know that this system is running are full of confidence in it.

"I hope it can really help several truly separated couples realize their dream of reunion. This is the purpose of our visit to the kinship search conference and the true meaning of our kinship search conference!" Mr. Dai Guoxun did not agree with Yang Lin and the others' fraud. Of course, he did not express his criticism, but just placed his hope on Yang Yan.

Yang Yan was not willing to give up. He stared at the computer screen intently, hoping that his system would achieve results and help more people.

However, he was not just sitting. While waiting for good news to be heard from the system, Yang Yan was also reflecting secretly, thinking about what else his system needed to improve.

You should know that the three groups of "support" mentioned by Director Yang only hit two groups, which is 66.67% accuracy. Such results are difficult to satisfy Yang Yan!

I don’t know how long it took, but suddenly, a prompt box popped up on Yang Yan’s laptop screen.

"Teacher Dai, there is new feedback!" Yang Yan reacted the fastest. He clicked the message happily. Seeing the matching value of "similarity of 87%", he couldn't help but turn to say to Dai Guoxun.

The similarity of 87% is already high beyond the 70% feedback standard set by Yang Yan (Yang Yan dared not adjust it too high for the first time). The similarity of the two groups just now was only 84% and 91%.

This shows that the probability of success is still very high!

Upon hearing this, Dai Guoxun immediately put on his reading glasses that he had taken off for a while and looked at Yang Yan's computer with bright eyes. Yang Lin and others who were drinking tea behind him were also surrounded by excitement.

Yang Yan found the two matching photos. Obviously, one was a surveillance video from the scene. After high-definition processing, everyone could see the person's appearance relatively clearly.

He is a young man dressed neatly and looks ordinary!

He wore a red plaid shirt, which looked a bit like the dressing styles of programmers in Yang Yan's company. From the perspective of mentality, this young man was not as haggard and unkempt as other people looking for relatives. Although he looked ordinary, his beard was very shaved and looked very gentle with glasses.

"He is here to look for relatives too?" Yang Lin stood behind and looked, unable to help frowning. He thought this was a very normal person, an ordinary office worker, who was grabbing a lot of people on the subway in Yangcheng.

Yang Yan also had the same doubts, but he believed in his system matching results more. Moreover, Yang Yan felt that all the surveillance videos came from the event site. If this young man was not here to look for relatives, what did he do here?

Coincidentally, another photo also came from the event site, a photo library of the search posters taken by the on-site staff and uploaded by the search staff.

Of course, when the system scans and matches, it will only cut out the portrait part in the search poster. What Yang Yan sees now is only a photo of a five- or six-year-old boy!

Fortunately, it was still a color photo, like a photo taken by his parents and children to the park to play, holding a film camera that was still very fashionable at that time.

It is obviously very difficult to be able to perform facial recognition across more than ten or twenty years. When Yang Yan wrote this program, he also spent a lot of time and consulted the genetics professor at Nanyue University for this topic and obtained some data support from him.

Of course, the system can match photos of different ages more accurately, thanks to the large number of face photos provided by Teacher Dai for Yang Yan. With a large amount of photo data, the intelligent human recognition system written by Yang Yan can automatically correct its matching algorithm through continuous learning.

This is why, the previous "Zhao Shang" was found by Yang Yan's system and matched his photos ten years ago.

It was a bit far away. Yang Yan now brought up photos of the original poster of the search for a relative and video of a young man wearing glasses in plaid shirt, preparing to ask the organizer to help find the young man and his relatives.

"Hey, I know this poster!" Before Yang Yan could speak, Director Jiang of the Civil Affairs Bureau reacted and said in surprise, "This is an old couple's poster for searching for relatives. Yes, the surname is Liang. They have been here last year, and they come very early every time. Moreover, they are the latest ones to go back. I even advised them. But seeing that they can't find their children and go back disappointed, I didn't know how uncomfortable it was... I said why did they look familiar just now!"

The couple surnamed Liang actually have contact information on posters, so it is not difficult to connect.

Now Yang Yan and his team's main task is to find the young man in plaid shirt wearing glasses. Regardless of whether he is really here to look for relatives or not, Yang Yan, Dai Guoxun, Yang Lin and Director Jiang are not willing to give up hope.
Chapter completed!
