"I spent a minute reviewing my nine years of compulsory education... and finally found out that I had been cheated!
Can anyone do this question?
The ‘Yuhua Stone’ mentioned in the question above, please explain it using ‘terminology’!”
“Of course humans can’t do it directly, so we need to introduce other data.
For example, if a kitten likes you, it has a b% chance of sticking to you and a % chance of purring.
So how do we know the probability that a 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 guinea pigs who have dedicated their lives to science won't agree!"
"The first question stumped everyone? Keep reading, the second question is even more perverted!"
"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 modeling marketing simulations, or for predicting disease risks and patient susceptibility, and I happen to be doing research in this area."
"Well! There are still talented people in the mathematics community in our school. Now someone can finally understand the questions."
"Ashamed! I can only understand part of this question, and the other part is beyond my reach."
"How high?"
"The Himalayas are so high..."
"Hi~ It's so scary?"
"The first two questions are so difficult, so isn't this third question going to be a breakthrough?"
"Please help me read the question."
"Bronze ball!"
"One hundred thousand tons of copper balls!"
"A million tons of copper balls!"
After queuing for a long time, someone finally stood up, and it was the ‘Yu Hua Shi’.
"I'm not sure, it seems like an artificial neural network ANN handles large and complex machine learning tasks.
It describes a set of interconnected layers composed of weighted edges and nodes, called neurons.
By training a neural network on input data to learn the relationship between input and output, multiple hidden layers can be inserted between the input layer and the output layer.
It works similarly to the structure of the brain, where a group of neurons is given a random weight to determine how the neuron processes 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.
There is also the particle swarm algorithm with random weights..."
"Hmm! Then what?"
"..."
"Haha! The boss has been thinking for a long time."
"..."
"Moxi Moxi? Boss 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 a person who talks only half the words."
"..."
"You end up living the life you hate the most..."
"Hey, hey, hey! I am a prestigious Shuimu Academy, a place where elites from all over the country gather, and I can't even tell you 1, 2, 3 how to read three questions?
Comrades, I am deeply worried about the academic future of our school’s mathematics department!”
"I only know that our basic subjects are weak. I didn't expect that we are so weak. No one can do it?"
"Hey! This is a discriminatory statement. Questions like this are simply not something ordinary people can understand. There are many "known" formulas in it that I, a doctoral student in the Department of Mathematics, have never seen before.
The guy from Yuhuashi upstairs said it right.
He has a problem with this issue itself!"
"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? I won't talk about it anymore, I'm going to solve the problem."
"Haha! With Chao Gang Chao being like this, are you sure you're not here specifically to compete in the gym?"
"Hmm! Maybe, you think...could it be the grandsons from Yan University next door?"
"Just them? Don't look at them who are clamoring for first place in subjects all day long. In fact, their level is only half as good as ours. I don't believe it anyway!"
"That's strange. Who is this 'Open Source Emperor Mengchangjun'? Is it the vest of a powerful figure?"
"Hey! I heard that Wei Yidong recently came out there. He is known as Wei Shen. He became an assistant professor at a young age. He is a very good person.
Do you think this ‘Open Source Emperor Mengchangjun’ 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!"
"The stars have changed, and the flowers and trees have changed?"
"Hiss! 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 large pants, was running towards the laboratory with a few warm A4 papers in his hand.
"Big 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 eat less, you won't starve to death!"
I pushed aside the few junior brothers and sisters I met on the road, and ran all the way into the laboratory regardless of everyone's surprised expressions!
"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 disciple in front of him.
He looked at his hands again.
"I'm back, where's my food?"
"Hey, just don't worry about the food for 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!"
Taking the pieces of printing paper handed over by the other party, Zheng Qiu glanced at them with some confusion.
"What is this... Huh?"
To be continued...
