Chapter 177 The Watcher
“I spent a minute reviewing my nine years of compulsory education... and finally found out that I was cheated!
Can anyone do this question?< br>
Please explain the 'Yuhua Stone' in the question above using 'terminology'!"
"Of course it's not possible to answer the question directly, so we need to introduce other data.
For example, if a kitten likes you, there is a b% chance of sticking to you, and a c% chance of purring.
So how do we know the probability that the kitten likes us? Through Bayes’ theorem, we can calculate it from the probability of belly turning, sticking and purring. "
"..."
"Gan! "
"Cat: Forget it, I don't like doing math! ”
"Cat: Either guess who I like, or guess whether I am dead or alive. Can I still have some privacy?"
"Tom, are you talking about privacy in front of me, Jerry? So many people have dedicated their lives to science. The mice didn’t agree!”
“The first question stumped everyone? Keep reading, the second question is more Abnormal! ”
“This seems to be a random forest problem, but it is much more profound than the current random forest algorithm.
It is generally used for marketing simulation modeling, or using To predict the risk of disease and the susceptibility of patients, I am doing research in this area. ”
"Well! There are still talented people in the mathematics field of our school. Now someone can finally understand the question."
"Ashamed! I can only understand part of this question, but I can't understand the other part." "How high is it?"
"The Himalayas are so high..."
"How scary is that?" br>
"The first two questions are so difficult, so isn't this third question going to break through the sky?"
"Please help me read the question."
"Bronze ball!"< br>
“One hundred thousand tons of copper balls!”
“One million tons of copper balls!”
After queuing for a long time, someone finally stood up, and it was the 'Yuhua Stone'.
“I’m not sure, this seems to be an artificial neural network ANN that handles large and complex machine learning tasks.
It describes a set of edges and nodes with weights that interact with each other. Connected layers, called neurons, are trained on input data. Neural network learns the relationship between input and output. Between the input layer and the output layer, multiple hidden layers can be inserted.
It works similarly to the structure of the brain, where a group of neurons are given. A random weight to determine how the neuron processes the input data.
As for what I can understand in this question...
When the data must be separated non-linearly, the feedforward neural network determines how to choose the number of hidden layers formula...
There is also random Weighted particle swarm algorithm..."
"Yeah! Then what? ”
“……”
"Haha! The boss has been thinking for a long time."
"..."
"Moxi Moxi? Mr. Yuhuashi? Are you still there?"
"..."
"Maybe he went downstairs to buy steamed buns?"
"Gan!"
"There are two kinds of people I hate the most,
one is the person who talks half the story."
"..."
"You end up living the way you hate the most..."
"Hey, hey, hey! I am a prestigious Shuimu University, a place where elites from all over the country gather, but I can't even tell you how to read three questions?
Comrades, I am very dissatisfied with the academic performance of the mathematics department of our school. I am deeply worried about the future!”
“I only knew that our basic subjects were weak, but I didn’t expect it to be so weak! , No one can do it?”
“Hey! This is subject discrimination. Questions like this are not understandable by ordinary people. There are many ‘known’ formulas in it. I'm a doctoral student in the Department of Mathematics and I've never seen him before.
The guy from Yuhuashi above said it well.
On this issue itself, he has a problem! "
"So, you have to be at least a professor to be able to talk about problem-solving ideas? "
"This question is so awesome, do you think the 10 million reward on it is also true? "
" How can we talk about money when it's vulgar and academic? No more talking, I'm going to solve the problem. ”
“Ha! With Chao Gang Chao being like this, are you sure you are not here specifically to compete in the gym? ”
"Hmm! Maybe, you think...could it be those grandsons from Yan University next door?"
"Just them? Don't look at them who are clamoring for the first place in the subject all day long, but in fact their level is only about the same as us. , I don’t believe it anyway!”
“That’s strange, who is this ‘Open Source Emperor Meng Changjun’? ? Is it the vest of a powerful figure? "
"Hey! I heard that there was a man called Wei Yidong recently, who became an assistant professor at a young age. < br>
Do you think this 'Open Source Emperor Meng Changjun' could be him? ”
"No way? I've seen that person before. He's very strong but very low-key. He wouldn't do such a ostentatious thing."
"Well...then I have a bold idea!"
“As time goes by, what’s the matter?”
“His! Roundworm!”
“It’s too late, someone has already done this! Someone has already reposted it on the Weiming BBS next door! ”
"..."
...
At this time, the "Yuhua Stone" himself, a slovenly young man wearing glasses and a shirt and shorts, was holding several pieces of A4 paper that were still warm in his hand. , running towards the laboratory in a hurry.
"Senior Brother!"
"Eh? Senior Brother, didn't you say you were going to eat? Are you back so soon?"
"Oh, what are you going to eat? If you miss one meal, you won't starve to death!"
Pushing away the few junior brothers and sisters I met on the road, regardless of everyone's surprised expressions, I ran all the way into the laboratory!
"Old Zheng, Old Zheng!"
"Huh?" A middle-aged man with unshaven beard and half-white hair who was typing in front of the computer raised his head and looked at the panting man in front of him. Disciple.
Looked at his hands again.
"I'm back, where's my food?"
"Hey, just don't worry about the food now, it's too rough!"
"Something happened? Is there a fire outside? It's so urgent."
"It's not a fire outside! It's a fire on the BBS! Look at this quickly!"
Taking the pieces of printing paper handed over by the other party, Zheng Qiu glanced at it with some confusion. .
"What is this... Huh?"
Rubbing his sore eyes from staring at the computer screen for a long time, he looked at the things in his hand word by word again.
The eyes gradually changed from confusion to solemnity, and then from solemnity to shock, and the eyes opened wider and wider.
More than ten minutes passed.
“Where did this...this thing come from?”
"Someone posted a post on BBS, offering high rewards for the answers to these three questions.
While I was eating, I took a second look out of curiosity, and found that some of the formulas in these questions were similar to The topic of 'Simulating Neurons' we are studying is very similar, and it actually gave me some inspiration. Send it.
And the more I look at it, the more profound it becomes.
I’m not sure. I just think there’s something wrong with this question, so I brought it back for you to take a look at before finishing my meal.
>
How is it? Do you see any clues? ”
"No."
"Damn it! You are just a professor Mizuki, but after watching it for so long you tell me that you can't tell anything?"
"Tch! You are still a postdoctoral fellow of Mizuki. Well, do you see anything?"
Zheng Qiu rolled his eyes at the other party.
Although they are his students, the relationship between the two is that of both teachers and friends, and their usual way of getting along is like a year-long friendship.
"It's precisely because I know more than you that I dare not say that I understand anything..." Zheng Qiu's face gradually became serious.
“Don’t say that we are engaged in computer mathematics. Even serious mathematicians may not be able to solve these problems.
Looking at these three problems alone, They should all be mathematical problems in the computer modeling process.
But I have never seen this kind of research idea in any mainstream research topic in the world.
The most incredible... ”
He pointed at a certain string on the third question with a strange expression on his face.
“Have you seen this function?”
“Well, I have never seen this function.”
“Of course I know you haven’t seen it.”
“……”
"If I'm not mistaken, this should be a function used to quantitatively measure uncertainty. I've been stuck here recently.
Let's put it this way, this function... it looks very much like what I want The answer..."
"What?"
"In other words, the other party must be doing something similar to us, and the research progress is many times ahead of us."< br>
The two stared at each other for a moment.
"Old Zheng, didn't you say that no one has done this subject of ours? You must have plagiarized it, right?"
"...Get out!"
"Uh...let's go It’s a joke, why are you so serious?”
“Who is kidding you, get out immediately, I want to study this function tonight!”
“…”
< br>
"Eldest Brother" walked out in a sullen voice, but suddenly froze in place after a moment.
Uh...what did Lao Zheng just say?
Study this function?
Instead of studying this question?
Hiss~ There is indeed a problem with this question!
Who is that "Open Source Emperor Mengchangjun"...?
……
At the same time, next door, Yan University.
The Weiming BBS forum was also bombarded with a bunch of question marks and exclamation points by three sudden questions.
As things gradually fermented, copies of these three questions gradually began to circulate in the circles of mathematics and computer-related professors...
"Brother Wei, Brother Wei! Come and take a look at this! You must be interested!"
With a steamed bun in one hand, Wei Yidong, who was working on his desk at the desk, raised his head and took the bun handed to him in confusion. Copy paper.
“What is it?”
Wei Yidong, known as the Wei God of the Department of Mathematics, has an unattractive appearance, with a chicken coop on his head and a dull look in his eyes.
At first glance, no one would associate such a young man with a professorial lecturer at the famous Yan University.
But everyone who knows him knows that this young, unkempt man is already a legend in the mathematics department.
He doesn’t play games and hardly participates in any social activities.
But he dedicated all his talent and youth to mathematics without any distractions.
No one can succeed easily.
No one can be called a scientist casually.
"Huh?"
Wei Yidong's movement of chewing the buns froze for a moment, and his pupils slowly dilated.
Mathematical formulas that looked like a book from heaven to others were like lightning bolts flashing through his heart, which was shocking.
He slowly put down half of the steamed bun, without even looking at anyone else, his eyes became extremely focused.
Then I slowly picked up the pen...
A seed thrown by Meng Lang caused ripples in the middle of the lake at Shuimu and Yanda, two top universities, and then gradually spread.
This night is destined to be sleepless!
……
The next day, nine o’clock in the morning.
Just after the market opened, Changchun Biotech received a sudden influx of large amounts of money, and its stock price began to rise linearly!
"Holy crap! What's going on?"
"It's 5% in the blink of an eye. Is this a big deal?"
"It's a high-priced stock. If the stock price continues to rise, it will be faster." Catching up with Maotai! Another Maotai!"
"Don't look at the short term, just look at the performance, this stock is good, hold it for the long term!"
"Brothers, I smell the dealer. The smell of entering! ”
“What a loss, I only made half a position yesterday!”
“Oli! Add chicken drumsticks today!”
“Strange, does anyone know what are the major benefits of Changchun Biological’s stock? "
"Stupid! If there is good news now, it will take two days. Do you still want to beat the news?"
"That's right."
"..."
The discussion forum was filled with joy.
Gao Yuan looked at the stock price that was rising violently every second, and an intriguing smile finally appeared on her lips.
Looking at the stock price, you can tell that someone must be impatient and take action.
At this moment, the last bird of killing three birds with one stone has finally fallen into the urn!
Calculating the time, it's almost time to close the net.
Open an external mailbox that has already been registered, then select the draft box and select to send an email that has been drafted.
Next, let the bullets fly for a while longer...
...
Su City Radio, Information Department.
"Leader, why can't I publish this article?" Liu Tao asked doubtfully, holding a manuscript in his hand.
"What did you write?" The radio station leader, who was fat and had only a few strands of "hair" left on his head, raised his head and gave him a helpless look.
“Tens of millions of deposits have disappeared, and the bank is under surveillance. The suspect has been arrested and confessed to the crime. Is there any problem with this?”
“No problem? ?”
Seeing Liu Tao still looking confused, the radio station leader said seriously.
"Liu Tao, you just came here not long ago, and the articles you wrote are a little too taken for granted, which I can understand.
But the angle you wrote is a little too one-sided. We who report must uphold a fair and impartial stance. Impartial, right?"
Liu Tao was a little confused.
"But I am not biased towards which side? I just reconstructed the case honestly, and then conducted an on-site investigation and analyzed the bank's internal supervisory procedures with hidden dangers.
This... Isn’t that a problem?”
"Of course there is a problem." Seeing that the other party was still stupid, the station leader had no choice but to point it out.
"If you write like this, you are almost putting all the responsibility on the bank. What do you want the bank to think?"
"But...but this matter is originally an internal matter within the bank. The fact that the bank's internal supervision process is a problem shows that there is something wrong with it.
Then I can't pass the responsibility on to the innocent depositor, right?"
"Why is there no responsibility? ?
He trusted the bank too much, trusted the account manager, and did not carefully check his bank statements. Isn't this the biggest responsibility? "
"This..."
"Okay, okay, it's the court's responsibility to determine whose responsibility it is, not ours!
What we need is to restore the true nature of the case. As for criticizing the bank, we should use less subjective words. Do you understand?
Go out and rewrite it and hand it in. ”
"...Yes, leader."
Comed out of the office somewhat dejectedly.
If a country is like a ship sailing on the sea, reporters are the watchers on the bow.
He wants to observe everything on the endless sea, examine the unexpected storms, shoals and reefs on the sea, and issue warnings in time.
Liu Tao was full of enthusiasm, but only after working did he realize the gap between ideal and reality.
"Alas!"
Sighed, and just as he was about to revise the manuscript, an email reminder suddenly popped up on the computer screen.
When I opened it, I saw it was a strange mailbox.
Liu Tao originally thought it was spam, but just glanced at it casually.
The next second, my eyes were involuntarily attracted to the content above.
The eyes opened wider and wider... (End of this chapter)
