It is obvious that the emergence of three new technologies, namely DNA testing, pattern detection and big data, has brought about an earth-shaking revolution in criminal investigation science.
But DNA testing is easy for people to accept. It’s so cool to be able to identify criminals right away! Picture detection is also acceptable. It’s doubly fun to catch criminals through live broadcast.
Because ordinary people can easily understand these two technologies. They are clear at a glance and quite convenient.
On the contrary, big data is different. In the beginning, a considerable number of stubborn old criminal policemen were internally resistant. This is like a QR code electronic wallet. It may take a minute to learn it, but a considerable number of middle-aged and elderly people are
Not willing to use it, not willing to learn it.
Especially those old criminal police officers with long seniority, high prestige, and strong voice will lead to stumbling and even being abandoned. Although there is no exaggeration in the domestic book, in order to take care of the usage habits of the elderly and superiors, what fax machines are used in 2020?
But it was also quite unsuccessful.
It is because the use of big data requires a threshold that is difficult for ordinary people to understand.
Let’s take weather forecasting as an example. In ancient times, wouldn’t today’s weather forecasting just mean observing the sky at night and calculating it with just a few fingers?
The ancients simply couldn't understand modern meteorological science and would only regard it as a magical means. But today's criminal police, in the words of a reborn agent, they are just a group of "primitive humans". How can they understand big data?
Of course, as a senior Internet project technical director, Li Yuan is quite familiar with this mentality and has rich experience in dealing with it.
To be honest, compared to the laymen outside, the big guys in the project team are the real trouble. They all have great personalities and all kinds of quirks, and they can be sent to a mental hospital without being wronged.
So, this scene is just a small case, you guys are still young!
"Everyone, welcome everyone to be interested in the Xiè Zhi system. Since this is the first generation version, there should be many imperfections. You are welcome to correct me. Thank you!"
Haechi is one of the mythical beasts in ancient mythology. It has high wisdom, understands people's speech and human nature. It can distinguish right from wrong, good and evil, loyalty and traitor. If it finds a treacherous official, it will knock him down with its horns, and then
Eat it in your stomach. It can tell right from wrong, and is also known as the divine sheep. It is a symbol of bravery and justice, a symbol of justice, "fairness and fairness", and "a bright world".
Therefore, in ancient yamen, there were usually portraits of Xie Zhi.
Here, Li Yuan just made up the name "Xiechi System" just to shock the bunch of rubes below.
"In the Haezhi system, the latest big data concepts are used. Basically there are - data core principle, data value principle, full sample principle, focus on efficiency principle, focus on correlation principle, prediction principle, information finding principle, machine
There are several aspects such as the principle of understanding people, the principle of intelligence and the principle of customized pointing.”
"First introduce the most basic mathematical principles. Including number theory, probability theory, statistics and other related mathematical knowledge. First understand the Fourier transform: f(t)=\mathcal^[F(w)]=\frac{\
Li Yuan didn't care whether the people below could understand or not, he just started writing down a series of mathematical formulas.
If it is a general report meeting, it should be explained in simple terms and carry out some popular science;
If you are facing investors, you need an exquisite PPT;
If it is an academic exchange among experts, the focus will of course be on practical information;
It would be enough if these critical and questioning people in front of them were unaware of their seriousness. You don’t need to let them understand at all, you just need to let them know how stupid they are?
Looking at the series of mathematical formulas, there was already silence underneath, and all the police officers were doubting life. These things are incomprehensible together, but separately...still can't be understood?
This is the crushing of knowledge. Some police officers have begun to consider the ultimate philosophical question - who am I? Where am I? What am I going to do?
Moreover, Li Yuan has a very bad taste. He actually gave a lecture for more than half an hour on this extremely boring mathematical theory?
Finding that almost all the police officers' eyes were distracted and their brains were about to be turned into idiots, Li Yuan finally showed a very hateful smile: "I'll introduce the mathematical theory here first. You all can't understand it anyway, I'm just playing the piano to a cow!"
(⊙?⊙)(⊙?⊙)(⊙?⊙)……
CNMB!
As the leader of the psychiatric project team, how could Li Yuan not have a poisonous tongue?
However, this extremely humiliating behavior of slapping the face and then whipping the corpse immediately aroused the indignation of the police officers below. Lu Dong took action and shouted: "Little turtle, did you do this on purpose? Let us listen to your nonsense."
Li Yuan sneered and retorted: "Don't you want to listen to principles? You are uneducated, and you still blame me? Isn't this a waste of everyone's time?"
What Chen Dong said just now was slapped on his face.
Chen Dong's face suddenly turned red and blue. Many policemen almost laughed, and at the same time added to Li Yuan in their hearts: MMP!
At this time, Cui Tianfang was already in a state of panic. If this continues, this little defense team member will definitely be sacked...right? I didn't expect that his temper would be so bad.
It's better to settle the matter as soon as possible. Cui Tianfang quickly interrupted: "I won't talk about irrelevant things. Xiao Li, just use your Xiezhi system to predict cattle thieves?" After a few seconds, he added, "
Work quickly and be united!"
Don't tell me, the preliminary work of these criminal police officers is quite solid. Not only do they have the detailed location of the crime, but also physical evidence and confessions, and even the surrounding mule and horse markets and slaughterhouses have all been inspected. After all, after stealing cattle,
You always need to sell stolen goods, right?
However, the strange thing is that none of the clues can be traced, and those cows seem to disappear out of thin air? So it seems that the task force seems to be very busy, arranging personnel to stay on guard every day, but in fact, it becomes completely clueless.
Are all these detectives idle?
Of course, the criminal police were at most doubtful about the Haechi system. They also wanted to test Li Yuan's teachings.
But Li Yuan doesn't care about the attitudes of those people at all. It's best to get results, and it doesn't matter if the calculation is wrong. Anyway, the weather forecast is not always accurate, at least it has been successful twice before.
The data sample this time is of high quality, detailed and accurate, so the calculation is very smooth.
Ten minutes later, Li Yuan finally put down his pen and pushed a piece of paper in front of Cui Tianfang amid the different expressions of the detectives: "Captain Cui, we have the result."
