When Xia Yu was having a good time with Luoluo in the bamboo forest garden, Yang Yan and Old Man Dai were still sitting in the monitoring room, waiting quietly, hoping that there would be good news of matching in the data fed back by the remote server!

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

Prior to this, the "Smart Recognition" system had already given two matching verifications and successfully found their loved ones for two families looking for relatives!

However, after Yang Lin saw the matching results, he was a little embarrassed and told Yang Yan that the results of the system matching were correct, but they could not be regarded as surprises, because these two groups of people were actually two of the three groups of "trust" arranged by the organizer.

After all, this is an officially organized family search activity, and Yangcheng Radio and Television Station came to record the program on the spot, if no one found their lost relatives as they wished after the whole day of activities, then the organizer would be embarrassed!

Therefore, the organizer privately arranged three groups of "trusts", of course, this cannot be regarded as trust, because they are all real cases found by the social welfare foundation, but they are just the reunion of relatives that happened in the past, and it is just a re-stage in this square!

"That Zhao Shang, because of an accident more than ten years ago, amnesia, and then in Yangcheng has been living a wandering life, the winter before last, when the Civil Affairs Bureau distributed winter supplies to the social homeless, his information was counted, and it happened that his sister has come to Yangcheng every year to look for him for more than ten years, and the people from the Civil Affairs Bureau identified him and helped him find his family...... "Yang Lin told Yang Yan the story behind these "trusts".

Although the two sets of matching results found are "trust", which cannot be regarded as meritorious service, everyone still recognized Yang Yan's system, and Yang Lin praised it even more, saying that this system does have a hand, and in the monitoring room, people who know that this system is running are full of confidence in it.

"I hope it can really help a few more pairs of real separated relatives to realize their dreams of reunion, this is the purpose of our visit to the family search conference, and it is also the real meaning of our family search conference!" Dai Guoxun did not agree with Yang Lin's deception, of course, he did not say anything criticizing, but pinned his hopes on Yang Yan.

Yang Yan was not reconciled, he stared intently at the computer screen, hoping that his system could make achievements and help more people.

However, he was not just sitting, while waiting for the good news from the system, Yang Yan was also secretly reflecting, pondering what his system still needed to improve.

You must know that the three groups of "trust" mentioned by Director Yang, his system only hit two groups, that is, an accuracy rate of 66.67%, and it is difficult for Yang Yan to be satisfied with such results!

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 happily clicked on the message, and when he saw the matching value of "similarity 87%", he couldn't help but turn his head and say to Dai Guoxun.

87% similarity, which is already high beyond the 70% feedback standard currently set by Yang Yan (the first run, Yang Yan didn't dare to adjust it too high). The similarity between the two groups was only 84% and 91%.

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

When Dai Guoxun heard this, he immediately took off his reading glasses and put them on, and looked at Yang Yan's computer with blazing eyes. And Yang Lin and others, who were drinking tea in the back, also surrounded excitedly.

Yang Yan found out the two photos that matched, obviously, one is a surveillance video from the scene, a photo with high-definition processing, everyone can see the appearance of the person relatively clearly.

He is a young man who is dressed up and looks ordinary!

He was wearing a red plaid shirt, a bit like the dressing style of the programmers in Yang Yan's company, and from the point of view of his mental appearance, this young man was not as haggard and unkempt as other people looking for relatives, although he looked very ordinary, his beard was quietly shaved, and he wore glasses, and he looked very gentle.

"He's also here to look for relatives?" Yang Lin stood behind and watched, he couldn't help frowning, he felt that this was a very normal person, an ordinary office worker, grabbing a lot of money on the subway in Yangcheng.

Yang Yan also had the same doubts, but he believed in the matching results of his system moreover, and Yang Yan felt that all the surveillance videos came from the event site, if this young man was not here to find relatives, what was he doing here?

Coincidentally, another photo is also from the photo gallery of posters in the hands of the people looking for relatives taken by the on-site staff at the event site.

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

Luckily, it was a color photograph of a parent who came to the park with their children to play with a film camera that was still very fashionable at the time.

It is obviously very difficult to be able to carry out face recognition across ten or twenty years, and Yang Yan spent a lot of time when he first wrote this program, and he also consulted a professor of genetics at Nanyue University about this topic, and got 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 Mr. Dai for Yang Yan, with a large amount of photo data, Yang Yan's intelligent recognition system can automatically correct its matching algorithm in continuous learning.

This is also why the previous "Zhao Shang" can be found by Yang Yan's system and matched with his photo ten years ago.

It's a bit far, Yang Yan has now called up the photos of the original poster of the family search, as well as the video of the young man in the plaid shirt wearing glasses, ready to ask the organizers to help find the young man and find 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 a poster of an old couple looking for relatives, yes, surnamed Liang, they also came last year, and they came early every time, and they went back the latest, and I persuaded them." But seeing that they couldn't find their children and went back disappointed, I didn't know how uncomfortable it was...... I said, "Why did you look familiar just now?"

Mr. and Mrs. Liang, the contact information here is actually on the poster, and it is not difficult to connect.

Now Yang Yan's main task is to find the young man in the plaid shirt with glasses, whether he really came to find his relatives or not, Yang Yan, Dai Guoxun, Yang Lin and Director Jiang are not willing to give up hope.

This is the hope that the old couple has been looking forward to for an unknown number of years!
