I made a copy at the police station

[Ding, mission completed, reward experience +1000, diamonds +5000]

Really can.

Li wanted to put his phone back in his pocket.

As long as you take the case yourself, guide the team to solve the case, and you can get rewards, then this game is very maneuverable.

As soon as he put his phone back in his pocket, it rang.

Li Xiang took a look and saw that it was Director Li calling.

"Director Li, what are your instructions?"

"What's the point? Li Xiang, quietly optimized the portrait recognition system? He also solved an unsolved case in Yuncheng. When will you show me this system?"

"I'm about to report to your leader, but you are still well-informed."

Li Zhongqing knew the situation here so quickly. Apparently someone in the guidance team tipped him off, but he didn't know who this person was.

"Some people from the unit have already called me to accuse me. They said that we have a good system and are reluctant to let it be used by the subordinates. I am still wondering, what system? When they told me, I found out. I didn't expect that I would actually let you do it. It’s done.”

Li Zhongqing explained, and Li Xiang realized that it was the people in the guidance group and the leaders of their original units who had raised the issue, and then he called Director Li.

"This is all thanks to the Sunway supercomputer. Without its computing power, I can't do anything."

"It seems the news is true. How is the Yuncheng No. 1 case now?"

Listening to Li Xiang's tone, Li Zhongqing confirmed the accuracy of the news and secretly marveled at Li Xiang's scientific research capabilities.

In fact, he also arranged for people to upgrade the portrait recognition system, but the progress has been very slow. Now at first glance, Li Xiang was able to complete it, and it only took a week. This suddenly shocked him.

He knew that Li Xiang's computer skills were great, but he didn't expect that he was so good at it.

He alone is worthy of an entire scientific research team.

This is not a genius, this is a monster!

That's why he immediately called Li Xiang to talk to him, but he didn't expect him to admit it.

"It can't be so fast. Besides, this period of time has been mainly focused on optimizing the system and the case of losing one's virginity. However, the Yuncheng No. 1 case should have a result soon. The task force has temporarily expanded by 300 people to investigate the female relationships of the 11 victims. I’ve sorted it all out and calculated the time, it’s almost over.”

There is great power in numbers. If 300 people spread the seeds, we will know soon whether there will be any results.

Yes, best.

If not, the clues may have been broken again, and the investigation direction needs to be reorganized.

Sometimes solving a case is like this. Once the direction is wrong, the investigation will be fruitless and time-consuming and labor-intensive.

Therefore, the direction is very important at the beginning of solving the case.

It's just that the Yuncheng No. 1 case is special. It has no direction. Now as long as it is a possibility, we must try it.

Find the truth through constant trial and error.

"Okay, the case is not urgent. You can send the software over first and I will take a look."

Li Zhongqing still couldn't restrain his curiosity and asked Li Xiang for the optimized portrait recognition system.

He wanted to see the performance of the portrait recognition system that Li Xiang spent a week tinkering with.

"Okay, I'll go back to the office and send it to you later."

Back in the office, Li Xiang sent the compressed package to Li Zhongqing.

After receiving the installation package sent by Li Xiang, Li Zhongqing came to the Portrait Recognition System Research Institute without stopping. He wanted to see how good Li Xiang's system was.

"Director Li, welcome to the institute for inspection. We don't know and we haven't made any preparations."

Faced with Li Zhongqing's sudden visit, project leader Sun Zheng was a little confused, why did the leader suddenly visit?

Did something happen to the institute?
Or is it something he doesn't know?

That's a big problem.

"Professor Sun, how is the upgrade progress of the portrait recognition system?"

Li Zhongqing asked straight to the point.

"The project is going well. The current recognition efficiency of the software has increased by 50% compared with before. Our programmers are still working hard to strive for another 30% improvement in the first quarter of next year."

Sun Zheng said with some pride that he was quite satisfied with the improvement data. At the same time, he was relieved. The leader was simply concerned about the research progress, so there was no problem. Their research and development progress was faster than the estimated time. More than a month.

"Very good, let me test the software."

Li Zhongqing was quite satisfied with the 50% to 80% performance improvement, so he asked Sun Zheng to test it.

"Xiao Wang, run the software and let Director Li take a look at our research results."

"Yes."

Xiao Wang connected their optimized system to the public security system, and then randomly found a photo and started testing it.

Seeing the system's smoothness and response speed, Li Zhongqing nodded again. The current system, in terms of smoothness and response speed, is indeed much faster than the previous old version.

After half an hour, the system had compared thousands of similar lists. This efficiency improvement was indeed obvious.

"Director Li, is this efficiency okay?"

"Yes, your progress is indeed very fast. By the way, I also have a portrait recognition system here, which was developed by a friend. Come and test it, and then evaluate how this software is."

After hearing Li Zhongqing's words, Sun Zheng finally understood why Li Ding came here this time. He wanted them to test a piece of software.

It is also a portrait recognition system consistent with their research direction.

He also became interested: "Oh, really? Is there anyone else working on the portrait recognition system? Let me learn."

Sun Zheng was speaking modestly. He did not believe that there was a team more professional than theirs in the field of portrait recognition in China. Only comparison could reveal which product was outstanding.

As the saying goes, whether your product is good or not depends entirely on the support of your peers.

Li Zhongqing handed the USB flash drive containing the compressed package to Sun Zheng, who gave the USB flash drive to Xiao Wang and said, "Xiao Wang, test this portrait recognition system."

"Yes."

Xiao Wang opened the compressed package and saw that it was only a hundred megabytes in size, which he didn't care about.

After clicking on it, the familiar screen and UI interface made Sun Zheng couldn't help complaining: "Isn't this just an old version that was used to fool things?"

Li Zhongqing was very familiar with the old version of the portrait recognition system. When he saw this icon and interface, he also had some doubts. Did Li Xiang send the wrong software?

Did he directly send the old version?
"The old version was over 300 MB, and this one is only over 100 MB. It should have been deleted."

Hearing Xiao Wang's words, Sun Zheng shook his head. At first, he was somewhat interested in this portrait recognition system that could attract Director Li's attention, but now he had no interest at all.I don’t know who has the courage to use this software to deceive Director Li. He will suffer a lot in the future.

"Do you want to take another test?"

Xiao Wang asked uncertainly.

"It's all installed, let's test it."

At this time, Li Zhongqing, retaining his last trust in Li Xiang, decided to give it a try.

"Yes."

Xiao Wang clicked the test, and the software ran normally, and the smoothness and response speed exceeded everyone's expectations.

When Sun Zheng saw this situation, the smile on his face disappeared immediately, and his eyes remained motionless as he stared at the photos that were constantly beating on the computer screen.

"This recognition efficiency..."

Even Li Zhongqing, who doesn't know much about software, was surprised when he saw this result.

Likewise, the comparison results came out in just half an hour.

According to the similarity percentage, arranged from high to low, the photo ranked first has a similarity of 95%, which is clearly the person they are looking for.

"Professor Sun, the test is over. Compared with the old version, the test efficiency has increased by 1000 percentage points. How is this possible?"

After the results came out, Xiao Wang was shocked at first.

"And I think this is not the limit of this software. The photos we choose are not much different from the photos in the database. If the facial shape of the portrait will change to a certain extent as the age increases, then it will be the test portrait. Identify where the limits of the system lie.”

"Continue to test and find an old photo to try."

"Yes."

The test continued. This time they increased the difficulty of the test and directly found an old black and white photo for the system to recognize.

However, the system's response speed is still very fast. In just one hour, more than 100 similar photos were given. They are still arranged in order from high to low similarity as before.

The test photos did not require manual comparison. They were all already selected people. Therefore, Xiao Wang recognized at a glance that the person ranked tenth and with a similarity of 81 was the person they were looking for.

This efficiency is terrifying.

"At the end of the test, the efficiency of this software has improved by 1400 percentage points compared with the old version."

"How is this possible? How is it possible?"

Sun Zheng panicked. Is this test result too exaggerated?

It directly crushed the research results that he was proud of and shattered his inner pride.

"Ding Li, who developed this software? Please tell me."

"Actually, you also know this person."

"I know too?"

Sun Zheng thought for a while, but he still didn't know who among the people he knew had a portrait recognition system that could surpass him by a long way.

If there is, you will definitely know it.

"Yes, you also know that he is Li Xiang who developed skull digital restoration technology last time."

"Is it him? Didn't he just complete the development of digital skull restoration technology? Completed a cross-professional strike so quickly?"

Sun Zheng was a little aggrieved. He knew Li Xiang's name and the digital skull restoration software shocked him at the time. However, he always thought that Li Xiang was an expert in skull restoration and was unlikely to threaten their field of portrait recognition. But I never expected that this day would come so quickly.

Moreover, he came directly with the finished product and caught himself off guard.

"I was also surprised, but what's even more surprising is what happened later. Guess how long it took him to complete the optimization of the portrait recognition system?"

"Two months?"

What Sun Zheng could think of was that Li Xiang had been optimizing the portrait recognition technology since he had completed the development of the skull digital restoration software. It has been two months now. This speed is really amazing. In order to study this software, their research institute spent only It's been a year.

Li Zhongqing shook his head, stretched out a finger and said, "One week."

"What? A week? How is this possible?" Sun Zheng felt that he was more shocked today than he had been in a year.

Such a powerful piece of software actually only took a week. He didn't believe anything: "Ding Li, I'm a software engineer. Don't fool me. How could this be developed in just a week?" ? How many people are there in his team? Not many, even with how many people there are."

Sun Zheng couldn't figure it out no matter how hard he tried, his CPU was almost burning out.

I also don’t understand, is this something a human can do?
"He is alone, but I helped him apply for the Sunway supercomputer for a week. I heard from Sunway that the Sunway supercomputer has been running at full capacity this week, and they are worried that Sunway can't bear it." Li Zhongqing laughed and said I feel like Shenwei's nerves are a little nervous. Supercomputers have computational redundancy, so there's no problem if they run at full capacity for a period of time.

"Using a supercomputer?"

Sun Zheng seemed to have thought of something, and said to Li Zhongqing: "Ding Li, there is something I want to trouble you with."

"Professor Sun, please tell me that we don't need to see each other."

"Then I'll be honest, this software is very good. Just like the previous skull digital restoration software, it should have an AI intelligent program embedded in it. Artificial intelligence is the mainstream development direction in the world. Li Xiang developed it in a week alone. Having used this software, I suspect that Li Xiang has a complete artificial intelligence system in his hands, otherwise it would be difficult to explain how he did this."

"What are you talking about? Li thinks he has an artificial intelligence program? Isn't that unlikely?"

After listening to Sun Zheng's words, Li Zhongqing thought it made sense at first, but after thinking about it, it was absolutely impossible: "The research and development of artificial intelligence is not something that small workshops like us can complete. Which company studies artificial intelligence? Isn’t his net worth starting at [-] billion? How could Li Xiang be able to develop artificial intelligence by himself?”

"I have a way to verify whether he has artificial intelligence."

Sun Zheng also couldn't believe that private individuals could own artificial intelligence systems, but other than this reason, there was really no way to explain what Li Xiang did.

"any solution?"

"That is to see whether the code he wrote was written by himself or by artificial intelligence."

"Let's have a look."

Li Zhongqing also wanted to know whether Li Xiang had artificial intelligence.

After hearing Li Zhongqing's agreement, Sun Zheng immediately unpacked the compressed package in the USB flash drive and used decompilation software to check Li Xiang's code.

I saw that Li Xiang's code was very clean, line by line, without any comments. Most people would feel confused when looking at his code.

Even Sun Zheng found some parts of his code difficult to understand.

But at this time, he could only bite the bullet and read down line by line, looking for patterns inside.

"Ding Li, I can be 100% sure that when optimizing this software, Li Xiang did use artificial intelligence. The code arrangement in this software has obvious machine syntax."

Li Zhongqing asked curiously: "How did you tell?" (End of Chapter)
