On the podium, Liu Pei was explaining seriously, eager to teach, and even seemed a little verbose.

But the police officers down there have long been impatient. Finally, someone couldn't help but say: "Sir Liu, is your mainland police so broken?" Can a mathematical formula catch a prisoner? So what do you need us police to do? Why don't you go straight to the math teacher? ”

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

"Do you have any scientific evidence? Broken eucalyptus is not a playhouse, you can't always talk nonsense? ”

"There's a scientific basis. We have already carried out pilot work in two places, Modu and Shannan Province, in the prefecture and city. Liu Pei hurriedly said.

"And the result? Can you talk about it? ”

"Uh...... No valid conclusions have been reached. Feeling that this sentence seemed a little ambiguous, Liu Pei hurriedly added, "There are indeed successful examples." For example, Li Gong next to me is one of the inventors and developers of the hedgehog system. He has three consecutive successful eucalyptus cases in Fengling County, Shannan Province. It's just that the other results are still being counted......"

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

In fact, although there are already two pilot areas, Modu and Shannan. But in such a short period of time, and a complete database has not been established, where does the result of the pig system come from?

Coupled with the Demon Capital Police, they have the most advanced equipment, the most abundant resources, and a group of tigers and wolves, the rate of breaking is extremely high. On a global scale, what can be fought is the soul of the imperial capital.

At present, with the addition of a rudimentary version of the hedgehog system, it really doesn't show much effect.

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

I can't allocate that amount of money at all, and I hope that the ministry can support it. That is, even the prerequisites for use have not yet been met.

Such a pilot? And how do you count it?

Moreover, there is also a lot of criticism within the mainland police, believing that this system is a waste of money and labor. This is very similar to the situation of the Hong Kong police – a collective rejection of the heresy of the tech stream.

As soon as he heard Liu Pei's words, the audience burst into laughter: "It turns out that you have no results yourself? Are you kidding us? ”

"Sir Liu, we are all very busy, why don't we joke less?"

"You in the mainland still honestly torture to extract confessions. Listen to my advice, Sir Liu, high-tech is not for you. ”

“……”

The continuous coaxing of the people below made Liu Pei's face flush. For a moment, he was a little at a loss.

Seeing that the situation was not good, Li Yuan hurriedly took over the topic: "Everyone, sir, be quiet, you are still in class." ”

"Baa class? Listen to your nonsense? A middle-aged man with a flat head sneered, "You broke the eucalyptus three times in a row? The blind cat touched the dead mouse, right? If all of this thing can be broken, the sow will go up the tree. Hahaha......"

Li Yuan didn't pay attention to the words of the flat-headed brother. I looked as usual and continued: "The future development of science and technology will definitely be inseparable from informatization and intelligence, and the system is the specific application of big data in criminal investigation science. As a cutting-edge science, there must be some imperfections, and it also needs to be continuously improved in practice. ”

It slowly fell silent. These Hong Kong police officers are very curious, what kind of flower can Li Yuan say? Many have a smile of disdain and mockery on their faces - you see, even they themselves admit to being "imperfect"? Are we still going to use this?

"I won't say much about the principle of big data. Liu Gong has introduced it in detail before. Li Yuan said unhurriedly, "In fact, in the big data of forensic science, it can also be classified into many sub-projects. For example, behavioral trajectory big data. Through certain behavioral habits, the suspect is locked. However, the biggest use of behavioral trajectories should be in business. Push specific products through shopping habits. I won't expand on it here. ”

"Then there's personality analysis big data. Through personality analysis, high-risk groups of people are targeted for crime. In fact, in daily work, you should have already used this method. Before was a habitual thief, theft eucalyptus focused on; If you have a eucalyptus bottom before, it is easy to become a repeat offender ....... There are even other extended applications. For example, if you live in a chaotic slum since you were a child, you will have a high probability of committing crimes when you grow up; Having been subjected to domestic violence since childhood, it is easy to get mental illness when you grow up, and there is a high probability that violent crimes will occur......"

"The other is the big data analysis of the flow of funds. This is aimed at economic crimes. It's not a simple regulation of the flow of money, it's about discovering common patterns and picking out suspicious targets......"

“……”

In Li Yuan's narrative, it is still very dry. The police officers below have gained more or less, and their attention has begun to slowly focus......

However, there are always a few thorns. Because the atmosphere has been ruined before, some people are still dismissive.

It's still that flat-headed guy. He interrupted suddenly: "What you said is so nice. Who knows if it's true or not? ”

Li Yuan smiled slightly: "Ladies and gentlemen, times have changed. Whether it's true or not, with the development of computer IT technology, all walks of life have undergone earth-shaking changes. You police are the same, you must keep up with the development of technology in the future, otherwise you will be eliminated by the times. ”

"Shh Brother Pingtou scoffed, "I know you, aren't you Brother Yuan?" I admit that we are not as good as you when it comes to talking nonsense, but what do you do? Where did you get the courage to point fingers at us? ”

The audience burst into laughter again. There were even a few people who booed.

Li Yuan looked left and right, and sneered: "Of course I know, your Hong Kong police are very awesome and very good at handling eucalyptus." It's so awesome that even a few people can't clean it up. It's usually like a brother and sister to those elders in the rivers and lakes, and I'm very happy, right? Let them find a little brother to blame, the breaking rate is very high, right? Hehe. ”

I'm picking!

Almost all the officers jumped up. This is the standard scolding and slapping in the face.

Unexpectedly, Li Yuan was endless: "So, you don't need to learn any criminal investigation techniques at all." This hedgehog system is given to you, and that is also a waste. In the future, you will simply change the name to the Xiang Police Hall, and all the eucalyptus sticks are double-flowered red sticks, so majestic and powerful! ”

I'll give you a lung!

The officers couldn't bear it anymore.

sneering at the bottom, Li Yuan was full of firepower: Since those Hong Kong police officers don't give face, why should they give them face? Lao Tzu has never been a person who swallows his anger.

mmp！ Brother Yuan, it's you who I'm scolding!
