Speaking of the principles of big data, how complicated is it really? That’s not necessarily true.
The simplest one should be to trigger keywords. This is widely used in business.
For example: if you like visiting online stores, you will push certain types of products; if you like certain news, you will push certain official accounts; if you like anchor girls, you will push certain female anchors;
If you browse some websites, the power company will come to your home to read the water meter...
What is more complicated is to obtain the required prediction results by analyzing data samples. This involves certain core algorithms.
In fact, the amount of calculation for one or two sets of data samples is not very large, just like Li Yuan can calculate by hand. The difficulty lies in deleting invalid data samples from the massive data samples and selecting a small number of valid data samples. And it can be obtained
Produce prediction results within a reasonable range. This requires a large server.
In some ways, big data and reasoning are similar, but they are also different.
Reasoning requires clues and logical deductions. If you encounter an unsolved case, reasoning can only lead to blindness.
Of course, big data also needs clues, but it mainly relies on brute force calculations. Anyway, if you hit it with a hammer, you will always get the result. As for whether it is accurate or not? Then just kill it and bury it.
Theft is one of the most difficult cases to detect. It is highly random and difficult to fix evidence. In addition, this cattle thief case is almost a headless case, and there are very few effective clues.
Therefore, when Li Yuan calculated the results, he himself was a little unconfident. Because the key words in the results were: "layman, development zone, truck, factory..."
In addition to trucks, we can also understand that after stealing cattle, they always need to be transported. Other keywords are... ridiculous, right?
Let’s talk about the layman. A theft gang that has troubled the public security bureaus of three neighboring counties is actually a layman? Isn’t it a bit funny?
Unexpectedly, Li Yuan was a little unsure, and the detectives started talking about it.
"The development zone is full of factories. No cattle rustling cases have happened there, right?"
"I guess rabbits don't eat grass near their nests? You can look at the map. There have been no thefts in this area. On the contrary, there have been cases in the surrounding towns."
"That's just a layman. In the past, our focus was on local second-rate people. Almost all of them committed petty theft near home. Some of them had never left their hometown at all."
"It makes sense. A layman's explanation is that there is no criminal record. They escaped from the sight of our platoon."
"Then why are there factories and trucks?"
"It is very possible that the cattle were stolen and transported directly to other places, without being sold locally at all."
"..."
After all, they were professional criminal police officers. They didn't care whether it was ridiculous or not. They started discussing the possibilities first. After all, these criminal police officers were well-informed and had been exposed to many more ridiculous cases.
Seeing that the discussion was almost complete, Cui Tianfang directly ordered: "Now start to lead the team in groups and inspect all the factories in the development zone. Focus on the factories with trucks. We must not miss a loophole."
"yes!"
At this point, what the task force is most afraid of is that there are no clues, not that the clues are accurate or inaccurate. No matter what, let’s get rid of all the people first...
…
After everyone took action, the entire command post became empty, leaving only Li Yuan, an idle person. He was too embarrassed to disturb others, so he simply found a corner to rest for a while. It didn't take long before he was completely trapped.
Dreamland.
It was almost four o'clock in the morning when Li Yuan was awakened by a burst of noise. Police cars kept coming back, and the excited voices of police officers were everywhere. Suspects were escorted in one after another, and the entire headquarters was filled with a cheerful atmosphere...
After waiting for a while, Cui Tianfang appeared in front of Li Yuan: "Xiao Li, thank you for your help. The case has been solved. It is still in the investigation stage, so I can't go into details. But don't worry, I will definitely give you a reward."
Cui Tianfang also breathed a sigh of relief. It was too tortured. If it was a murder case, it would make sense. But just a mere theft case? It almost tormented the county bureaus of three counties to death!
Since he was able to solve the case, Li Yuan was also very happy: "Then Captain Cui, I should be fine, right?"
"Oh, I'll see if any car is available and I'll arrange to take you back to Xiashan. But I'm busy recording a confession right now. Could you please wait a little longer?"
Hearing this insincere promise, Li Yuan smiled: "I'd better wait until daybreak and I'll take the shuttle bus!"
"That's okay! This time the reception was not good. It was a neglect, a neglect."
"hehe."
…
After dawn, Li Yuan took the first bus to the county seat, and then took another bus back to Xiashan Township. When he arrived at the township police station to pick up his bicycle, it was already almost three o'clock in the afternoon.
He waved his hands and said goodbye to Wang Quan and several colleagues: "Uncle Quan, the case has been solved. Yuan and others should go home soon. Then I won't come here anymore?"
Wang Quan was a little reluctant to leave, and he was very happy for Li Yuan: "You little soul should have gone away long ago. Don't worry, I will get more subsidies for you, and the bureau will also give you a reward, right?"
"Forget it, forget it. Haha." Li Yuan doesn't care about those things at all. He won't get involved in the system in the future.
On the way back, Li Yuan suddenly thought about those criminal squad members. Aren't they trying to burn bridges by crossing the river? They didn't even send a car? He should have become a public enemy of the criminal squad, right?
But being slapped in the face and whipped to death is so cool! And now that it’s over, you can go away and hide your merit and fame. It’s so cool!
It's just a little strange, that... let's call it the Haechi system! The success rate of the Haechi system is too high, right? Three hits in three shots as soon as you take the shot? This seems to be no longer luck, there must be a certain reason.
When Li Yuan thought about it carefully, he discovered that in addition to the level of control at the grassroots level, as the legal system improves in a few decades, they will pay more attention to procedures. Whether it is law enforcement or solving crimes, the police are a bit soft.
"Sissy" look.
Unlike now, the style is strong and ferocious. If there is suspicion, you will be arrested first. With overwhelming one-shot transactions, you are not afraid of being caught wrongly.
In the future, if someone is caught and misplaced, he or she will receive compensation from the state. If he or she is caught and misplaced, he will receive compensation from the state. If he is misplaced, he will actually beat gongs and drums and come over to deliver banners with tears of joy?
So... we should still admit that the subsequent civilized law enforcement and protection of human rights are progressive!
But having said that, if it were placed in this period, a brute-force cracking of big data, coupled with powerful and ferocious crime-solving methods, would be a truly perfect match!
It is a pity that big data was born at the wrong time!
