On the podium, Liu Pei was explaining seriously, wanting to teach everything he could, and even seemed a bit verbose.

But the police officers below had long been impatient. Finally, someone couldn't help but said: "Sir Liu, is this how your mainland police crack down crimes? Can you catch the criminal by just using a mathematical formula? Then we, the police, are still needed

Why? Why not go directly to the math teacher?"

Liu Pei quickly explained: "This is called big data. Although it uses mathematical methods, it can effectively improve the success rate of breaking the eucalyptus..."

"Then do you have any scientific basis? It's not like playing tricks, so I can't just let you talk nonsense?"

"There is scientific basis for this. We have already launched pilot projects in Shanghai and Neizhou City, Shannan Province." Liu Pei said quickly.

"Then what's the result? Can you tell me something?"

"Well... we haven't reached a valid conclusion yet." Feeling that this sentence seemed a bit ambiguous, Liu Pei hurriedly added, "There are indeed successful cases. For example, Li Gong next to me, he is

One of the inventors and developers of the Haizhi system. He has had three consecutive successful cases in Fengling County, Shannan Province. But other results are still being counted..."

Liu Pei has the honest nature of a technical nerd. He is so scientific even when he lies?

In fact, although there are already two pilot areas, Modu and Shannan, a complete database has not been established in such a short period of time. Where do the results of the Haichi system come from?

Coupled with the Imperial City police, they have the most advanced equipment, the richest resources, and a group of tiger and wolf warriors, and the crackdown rate is extremely high. On a global scale, the only ones that can be defeated are the souls in the Imperial Capital.

Lost.

At present, adding a rudimentary version of the Haechi system does not really show much effect.

As for Shannan? Please buy a computer first. Thank you!

We can't allocate the funds at all, and we still hope that the ministry can support it. In other words, even the prerequisites for its use have not been met.

Just a pilot like this? How should we calculate the statistics?

Moreover, there is also a lot of criticism within the mainland police, who believe that this system is a waste of people and money. This is very similar to the situation of the Hong Kong police - a collective rejection of technical heretics.

Upon hearing Liu Pei's words, the crowd burst into laughter: "So you have no results? Are you kidding us?"

"Sir Liu, we are all very busy, why don't you stop joking?"

"You in the mainland are still going to torture and extract confessions. Listen to my advice, Sir Liu, high technology is not suitable for you."

"..."

The constant booing from the people below made Liu Pei's face turn red. For a moment, he felt a little at a loss.

Seeing that the situation was not good, Li Yuan quickly took over the topic: "Sir, please be quiet, we are still in class."

"What class are you taking? Are you listening to your nonsense?" A middle-aged man with a crew cut sneered, "You broke the eucalyptus three times in a row? A blind cat encounters a dead mouse, right? If these things can break eucalyptus, sows will climb trees.

.Hahaha……"

Li Yuan ignored the words of the flat-headed brother. I looked as normal and continued: "The future development of science and technology will definitely be inseparable from informatization and intelligence. The Haichi system is the specific application of big data in criminal investigation science. As a subject

Cutting-edge science definitely has some imperfections and needs continuous improvement in practice."

It gradually became quiet down below. These Hong Kong police officers were very curious, what kind of flower could Li Yuan say? Many people had disdainful and mocking smiles on their faces - come and see, even they themselves admitted it

Is it "imperfect"? Are we still allowed to use this crap?

"I won't go into details about the principles of big data. Liu Gong has introduced it in detail before." Li Yuan said unhurriedly, "In fact, big data in criminal investigation science can also be classified into many sub-projects. For example,

Let’s talk about behavioral trajectory big data. We can identify criminal suspects through certain behavioral habits. However, the biggest application of behavioral trajectory should be in business. Push specific products through shopping habits. I won’t go into details here.”

"There is also the big data of personality analysis. Through personality analysis, we can identify high-risk groups for crime. In fact, in daily operations, you sirs should have already used this method. In the past, we were habitual theft offenders, so we focused on theft; before

If you have a criminal background, you can easily become a habitual offender... There are even other expanded applications. For example: if you live in a chaotic slum since childhood, the probability of committing a crime will be high when you grow up;

It is easy to get mental illness later, and violent crimes are likely to occur..."

"The other is big data analysis of capital flows. What is targeted here is economic crimes. This is not a simple supervision of capital flows, but the discovery of common patterns and the selection of suspicious targets..."

"..."

Li Yuan's narration is still very informative. The police officers below have gained something, and their attention has begun to slowly focus...

However, there are always a few thorns in the side. Because the atmosphere has been ruined before, some people still dismiss it.

It was the guy with the flat head again. He suddenly interrupted: "What you say sounds so nice. Who knows if it's true?"

Li Yuan smiled slightly: "Sir, times have changed. Whether it is true or false, with the development of computer IT technology, all walks of life have undergone earth-shaking changes. The same goes for your police. You must keep up with the development of technology in the future.

Otherwise, we will be eliminated by the times.”

"Hey!" Brother Flathead sneered, "I recognize you. Aren't you Brother Yuan? I admit that we are not as good as you when it comes to talking nonsense, but how about doing it? Where do you get the courage to point fingers at us?"

The crowd burst into laughter again. A few people even booed.

Li Yuan looked around and sneered: "Of course I know that you Hong Kong police are very awesome and know how to deal with crimes. You are so awesome that you can't even clean up a few gangsters. Normally, you are brothers with those gangsters."

, are you very happy? Let them find a younger brother to take the blame, and the probability of detection is very high, right? Haha."

I choose!

Almost all the police officers jumped up. This was a standard insult and slap in the face.

Unexpectedly, Li Yuan continued: "So, you don't need to learn any criminal investigation techniques at all. It's a waste to give this Haezhi system to you. You can simply change the name to the Xiang Police Hall in the future, and everyone will go out to handle cases."

It’s a red stick with double flowers, so majestic and powerful!”

What the heck!

The police officers were even more intolerable.

Sneering at the people below, Li Yuan went all out: Since those Hong Kong police officers don't give them face, why should I give them face? I have never been a person who swallows his anger.
Chapter completed!
