Chapter 26 How could it be a video hall?
It's already time to get off work. It's the male police officer Liu Meng's turn to take a rest tonight, and the female police officer Liu Yanyan will stay on duty. Of course, Wang Quan will also stay at the station 24 hours a day. It is estimated that if the cattle thief is not caught, the old policeman will not be able to return home.
But there are advantages to having a policewoman. At least she can cook and everyone can have a hot dinner.
While waiting for Liu Yanyan to cook dinner, Wang Quan also came over and sent out a circle of cigarettes while taking advantage of this rare moment of rest. They all said, "What funny thing did you just say? Are you laughing so loudly?"
"Wang Suo, Yuanzi made some kind of program and said he could help catch the thief. That's it..."
Zhao Gan talked about some ridiculous results of using big data to catch thieves, just as a joke.
In fact, machine language and basic mathematics are cold and emotionless, and sometimes the results they produce completely violate human common sense.
For example, on a football field, with 22 players and 3 referees, what is the probability that more than two people have a common birthday?
The answer is more than 50%.
This is a very typical probability theory trap, which is used by casinos to cheat money.
There is also gender selection. In addition to male and female, there are actually "other gender" options? (This was an early programming BUG. Later database software made up for this loophole.)
Of course, later on, there were more than 60 gender selection items on European and American websites? Those human rights organizations were indeed happy. But now, such a classification is more ridiculous.
Li Yuan didn't think too much about Zhao Gan's good-natured joke.
This program is not even a prototype. In addition, there is no computer-assisted calculation at all, and the error is astonishing. Therefore, it is quite normal to get some ridiculous results.
Unexpectedly, Wang Quan's focus was not here. He smiled and said: "Actually, this is also possible? The probability of success is 20%, which is already very high."
Li Yuan quickly explained with a smile and could not mislead Wang Quan: "Uncle Quan, it is basically reverse cause and effect, so the success rate is higher. Also, it points out the trend, but cannot clearly indicate which person, which place or which case.
, so the practicality is almost non-existent.”
Since all the cases provided by Zhao Gan are already solved, using these cases as data samples and conversely making inferences, it is of course easy to get correct results.
There is also the practicality. For example, you know that a thief touched a bag at the market, but you don’t know when he stole it or whose bag he touched?
I know that a thief came to steal from my house. I only know that he is in these communities, but I have no way of knowing which one he went to?
So it can't be used to solve the case at all. To put it bluntly, it's better to find a few more informants.
Regarding Li Yuan's explanation, Wang Quan nodded thoughtfully. He has been a policeman all his life and has extensive work experience, so he can certainly understand what Li Yuan said.
After a while, Liu Yanyan served several large bowls of spicy noodles: "Eat it while it's hot. Yuanzi, try my sister's cooking."
Li Yuan was also hungry. Moreover, the spicy soybean noodles had a pure taste, and the smell of it made people appetite. The thick layer of spicy oil in the noodle soup was covered with garlic leaves, chopped green onions and chive flowers.
Seeing that Li Yuan was eating happily, Zhao Gan smiled and said: "Yuanzi, eat more. I hope there will be less things in the middle of the night, otherwise you will be hungry."
Unexpectedly, Wang Quan suddenly said: "Who said there would be nothing in the middle of the night? Get ready for action tonight."
"Ah? Wang Suo, didn't you hear what happened?"
"Haha, isn't Yuanzi doing that thing?"
"Ah? Wang Suo, you don't take it seriously, do you? Use this unreliable thing to catch a thief?" Zhao Gan was shocked.
Wang Quan smiled and shook his head: "How are we going to catch the thief? Who can we go to in the middle of the night?"
"What do you mean?"
"Yan Yan is here today, so let's go catch the boat (an alternative word for river crab)." Wang Quan smiled like an old fox, "Yuanzi, you can catch thieves, but you can also catch boats, right?"
Li Yuan was already dumbfounded. Uncle Quan must not have drunk too much, right? And Zhao Gan was absolutely right, that thing was not reliable at all.
"Yes, yes. But I have to explain in advance that this program can only be used as a reference, and the accuracy of the reference is not very high." Li Yuan quickly reminded.
Wang Quan waved his hand nonchalantly: "You don't have to worry about the rest. I won't blame you if I don't catch him. As soon as I was delayed by that cattle thief, the indicators in the institute this year will be tense. I'm still thinking about what to do before retiring.
, a small three-wheeler to generate income for the institute. Alas!"
During this period, many grassroots police stations had income-generating targets for catching boats and gambling. Regardless of whether this policy was good or bad, it was a special situation at that time. There was a lack of funds everywhere, even the Public Security Bureau's funds were very tight.
Now that Wang Quan had made his decision, several people began preparations for the evening operation.
At this time, two more joint defense team members came over. Only one of the five of them stayed during the day, and they took turns on duty at night. They all gathered on market days. Therefore, Wang Quan took good care of Li Yuan.
However, Li Yuan still looked confused. This is so unscientific! Did he actually participate in solving the case with live ammunition without using any paper program on the computer?
Sure enough, after inputting the data samples and Li Yuan calculated the results, several people burst into laughter: "Video hall? How can it be a video hall?"
Li Yuan was also helpless: "Uncle Quan, this is just mechanical calculation. I can only say that the video hall has the highest probability."
Zhao Gan looked disapproving: "I say Wang Suo, isn't this too unreliable? We really want to seize the boat, but the second best is the widow's family."
This time, even Liu Yanyan supported Zhao Gan's statement: "Wang Suo, this is obviously impossible. The video hall is opened in the original movie theater. How should men and women deal with each other in public?"
Another joint defense team member reminded: "The Lin brothers who open the video hall, I heard that there are people in their county. I haven't heard that they have any violations of law or discipline. At most, they play pirated video tapes. Even the Cultural Affairs Bureau doesn't care about this kind of thing."
"
Hearing everyone's objections, Wang Quan grinned relaxedly: "The town is not big anyway, and it doesn't take much effort to go around in a circle. Let's go to the video room as a check. If there is nothing, let's go to the Niu Widow's house."
Li Yuan had vaguely felt that in fact, even Wang Quan was quite skeptical about such a result. The reason why he did this was simply to support himself, the care of the elders for the younger ones, for fear that Li Yuan would lose face in front of outsiders.
.
"Stop talking nonsense." Wang Quan clapped his hands, "Get everything ready! Set off on time at 9:30 in the evening!"
"Yes!" Several other people looked at each other with helpless expressions and weakly agreed.
