Chapter 176 You Call This Simple

As the system zoomed in on several suspected surveillance images, everyone quickly found the target person in the photo in one of the images.

The first round of testing went so smoothly that the atmosphere in the entire command hall became much more celebratory.

"found it."

"The one in the middle is Xiao Liu."

“That’s really efficient.”

Although Li Gaoke had heard Jiang Jiaming talk about their technology more than once, what he heard was different from what he saw with his own eyes.

At this moment, he was completely immersed in joy. He didn't expect that he would find the target person so efficiently.

You should know that Jincheng is a pilot city for the Skynet surveillance system, and a large number of surveillance devices have been deployed and installed, and the target person’s location is randomly selected.

But relying on the system function, the location can be determined so quickly. If it is the suspect, then he has already been caught.

Thinking about the significant increase in the crime-solving rate, he couldn't suppress the smile on his face.

At this time, Jiang Jiaming's mouth corners also slightly raised, and then turned his head to Guo Zhihang and Zhu Minfeng and instructed:
"Continue with a new round of testing and increase the difficulty."

With the successful example of the first round of testing, Jiang Jiaming felt a lot more at ease.

More and more confidence in their skills.

The so-called increased difficulty requires the target character to change clothes and move around in the picture.

No longer standing completely still in the surveillance camera's view like before.

After receiving the diameter, Guo Zhihang and Zhu Minfeng kept moving and immediately began a new round of tests that had been arranged long ago.

But perhaps due to the increased difficulty, the target person did not exist in several suspected images given by the system in the second round of testing.

This means that the result was wrong.

When comparing the photo with the Skynet surveillance footage, the correct result could not be selected.

The sudden situation undoubtedly poured cold water on Li Gaoke.

The smile that was on his face just now suddenly disappeared.

Surprised, he could only look at Jiang Jiaming next to him, wanting to know the reason.

Jiang Jiaming saw that the thing he was most worried about had happened. At this time, he could only withstand the pressure and said to Guo Zhihang and Zhu Minfeng: "Continue the test and increase the number of suspected images given by the system."

"Okay, Professor Jiang."

At this time, Guo Zhihang and Zhu Minfeng also felt the pressure. Although their hands were still flying quickly on the keyboard, beads of sweat began to appear on their foreheads over time.

However, when the system gave more suspected images again, they were still not the target person after being enlarged.

Even Professor Dai Zhigang, who was standing behind him, couldn't help but shake his head with some regret when he saw this situation.

"The error rate of the results given by the algorithm is too high. I'm afraid today's test will end in failure."

When Li Hao heard this, he couldn't help but ask, "Is there any way to reduce the error rate in this situation?"

"Some parameter values ​​need to be adjusted, but this is difficult." Dai Zhigang thought for a while and gave this answer.

It is easy to adjust the parameter values, but how to adjust them to ensure the accuracy of the algorithm results is still unclear.

This often requires a lot of time and effort for continuous optimization, and it is impossible to solve this problem today.

While Dai Zhigang and Li Hao were talking in a low voice, Li Gaoke naturally realized the seriousness of the situation.

Although no one wants to see this situation, how can a brand-new technology application guarantee 100% success?

The most important thing right now is how to deal with this matter.

"What should we do in this situation, Professor Jiang? The news media are still waiting downstairs."

When Director Li said this, Jiang Jiaming had already come behind Guo Zhihang and Zhu Minfeng, his eyes fixed on the numbers on the screen.

"The error rate was clearly under control during the previous test, so why did it spike so much today?"

“Could it be interference from different environments outside?”

Guo Zhihang and Zhu Minfeng were also a little flustered at this moment.

I really want to reduce the error rate of the results, but I dare not easily adjust the existing algorithm parameters.

Otherwise, the result may be even more wrong.

After about two or three minutes, Jiang Jiaming seemed to have made a decision and stood up to face Li Gaoke.

"Bureau Li."

"Please give us some time. I need to adjust the algorithm parameters to improve the accuracy."

Hearing this, Li Gaoke did not directly refuse, but asked: "Are you sure about this?"

After all, if today's test really cannot be carried out, then we can find a reason to let those news media leave and choose another time to report and publicize.

If you continue to wait and the error rate still does not improve, it will have a negative impact.

Jiang Jiaming naturally understood the meaning of this, but he finally gave a positive answer.

"The people here today are all top figures in the computer field. If I ask for help, I am sure I can reduce the error rate."

Now that things have turned out this way, he can only place his hopes on Xu Yuan.

I thought that as the developer of the core algorithm, Xu Yuan might be able to perform positive optimization of the parameters in a short period of time.

Of course, he didn't expect Xu Yuan to modify the parameters very well. As long as it looked acceptable on the surface, it would be fine. After all, the time he had was very limited.

By then they can continue to optimize in private.

Li Gaoke met Jiang Jiaming's determined gaze, and after a slight hesitation, he chose to believe Jiang Jiaming.

"Okay then." "Just do as you say."

Almost as soon as Li Gaoke finished speaking, Dai Zhigang behind him took a step forward.

He muttered to himself: "I can only try to adjust as much as possible."

Among all the people present, apart from Jiang Jiaming, he was the only one researching in the computer field, so it was natural for him to step forward and help at this time.

Even if the final result is not ideal, you still have to do what you have to do.

In his opinion, this was also the reason why Jiang Jiaming invited him over.

However, when he walked towards the computer, he was surprised to find that Jiang Jiaming had come to Xu Yuan.

Especially what he said next, which completely stunned him.

"Professor Xu."

"Now I can only rely on your help. I will fully cooperate with you."

Looking around, I saw Jiang Jiaming personally inviting Xu Yuan to help, and even willing to assist.

What's happening here?
Dai Zhigang knew that Xu Yuan was a mathematical genius, and learned from Academician Song Wencong that the other party had also designed the launch layout of stealth fighter jets, but these belonged to different fields from computer algorithms.

No matter how you look at it, there is no reason for Jiang Jiaming to look for Xu Yuan.

Could it be that I can't see him?

What’s even more frightening is that Li Gaoke didn’t react at all, as if it was a matter of course.

The expression on Zhu Minfeng's face looked like anticipation.

Guo Zhihang was the most outrageous. He gave up his seat before Xu Yuan said a word.

"Professor Xu, please sit here with me."

Not only Dai Zhigang was confused, but Li Hao next to him was also confused.

His eyes shifted between Xu Yuan, Jiang Jiaming, Guo Zhihang and Zhu Minfeng's faces.

I really want to see something.

Unfortunately, I looked for a long time but found nothing.

Xu Yuan didn't expect that as a guest, he would eventually not be able to escape the fate of having to do it himself.

But in the current situation, the technology is based on our own machine learning algorithm, and we certainly don’t want to see it end in failure.

So I had no choice but to agree.

But at the end he added one more condition.

"It's just a simple modification of a few parameters, and I can do it myself."

After saying that, he walked towards the seat vacated by Guo Zhihang, and he looked confident throughout the whole process.

When Dai Zhigang heard this, he had no idea what to say.

Modify several parameters of the algorithm.

You call this simple?
Unable to hold back any longer, he immediately shouted to Xu Yuan, "Professor Xu, do you also understand computer algorithms?"

Jiang Jiaming felt relieved when he saw Xu Yuan agreed so readily.

He did not express any objection to Xu Yuan's request to modify the parameters on his own.

After all, the core algorithm was originally developed by Xu Yuan, so it would be much easier to modify it. If the two of them cooperated with each other, the efficiency might be reduced a lot.

Therefore, after hearing Dai Zhigang's question, he immediately turned around and started to explain with a smile on his face.

"Old Dai, don't you know that Xu Yuan's level in the computer field is higher than mine?"

"Taller than you?" Dai Zhigang's face was full of disbelief.

"Of course. The algorithm used in our project was developed by Xu Yuan."

"Professor Yao Qizhi of our school is eager for Xu Yuan to come to the School of Computer Science. Unfortunately, his mathematical talent is so high that he can only study computer science on his own." Guo Zhihang took over Jiang Jiaming's words and explained the situation about Xu Yuan to Dai Zhigang.

At this time, after hearing what the two said, Dai Zhigang's heart was suddenly filled with turmoil.

He naturally didn't think this was a lie, not to mention that even Yao Qizhi gave such an evaluation.

But thinking of Xu Yuan's amazing achievements in mathematics, he also studied engineering mechanics and designed an aerodynamic layout in his freshman year, which was used in the latest generation of domestic stealth fighter jets.

Nowadays, people who learn computer technology by themselves can develop powerful algorithms and have them recognized by many professors in this field. This is simply unimaginable for others.

"This is simply incredible. I didn't expect Professor Xu to have so many hidden talents."

Facing Dai Zhigang's exclamation, Li Hao next to him also kept his gaze firmly on Xu Yuan, not concealing the admiration in his eyes at all.

The most important thing is, at this point, he can't even be sure if Xu Yuan has any other surprises!
As time passed, everyone remained silent, for fear of disturbing Xu Yuan.

I don't know how much time had passed before the atmosphere in the command center hall was interrupted by two simple words uttered by Xu Yuan.

"All right."

It instantly attracted everyone's attention.

As the developer of the core machine learning algorithm, Xu Yuan quickly found the problem using his own method and modified and adjusted the problematic parameters.

The whole process did not take too long and was easy.

Then he stood up and gave up his seat again. After noticing everyone's expressions, he said in surprise: "Why are you all looking at me like that?"
