"????" Han Ci's eyes widened in disbelief. The last time she saw her teacher, she had a rare meeting and discussed some contents in detail. Not even Dean Fu told him the preliminary direction discussed with Academician E.
But this guy with a fairly average level of mathematics guessed 70% to 80% of the time? ?
Meng Fanqi knew what the girl was thinking when he saw this expression, "My brother is average in mathematics, but the idea of residuals and related experiments were actually done by me. Just pretend that I don't understand anything. chant?"
"So you understand? Really or not." To be fair, Han Ci had never seen geniuses of his own age.
But the most terrible thing about this kind of thing is actually the freshness brought by the contrast between expectations and reality. If these words were said by someone who is also a math genius, it would be meaningless. Even if he is a minor, Han Ci would not be surprised.
However, after hearing such an accurate guess from Meng Fanqi, a man with an average level of mathematics and physics, it was hard for Han Ci not to become curious about this person.
"Then, Author Meng, tell me what you think." Han Ci then thought about it and realized that this was a good thing. Although he doesn't understand much, as an author, his understanding is naturally deeper and more unique than most people.
Since he can guess what he is thinking, let's see what he has in mind.
"This perspective is to view the entire network as a dynamic system. It is said that neural networks are black boxes, and no one can figure out what is done in them." Meng Fanqi recalled that the main point of view of Academician E Weinan in this regard is From the perspective of dynamical systems.
"If you look at the problem this way, you can summarize the design of many network structures. It can be regarded as an inclusive idea. From this perspective, you can summarize my residual idea as a small branch of the theory." Meng Fanqi said with a smile. .
His own initiative this time seems to have caused Academician Hubei to start paying attention to this issue in advance and put forward relevant speculations and ideas earlier.
"The dynamic system is a bridge. Through the equivalence between your residual ideas and the state of the dynamic system, you can introduce many concepts from mathematics and physics to explain many phenomena." Han Ci did not think about generalizing other people's methods. Come in.
She is more curious about why this method is so powerful. The substantial performance improvement for two consecutive years has almost surpassed the progress made in the past few decades.
"Pushing forward, we can explain many problems and phenomena. Pushing back, we can design the network based on theory. How greedy. It's just that neural networks involve repeated transformations of many dimensions. If we solve it purely in this way, Or we can only stay at toy-level networks and data.”
"That's true... Once the design repeatedly transforms multiple dimensions, analysis will be completely difficult."
"The dark clouds covering the sky of deep learning have been cleared by me. The dark clouds covering the explainable theory depend on you." Meng Fanqi's words were not only a joke, but also a sincere blessing.
He led Han Ci to a small shopping mall near the school.
Outside the North Fifth Ring Road, it’s hard to go up the consumption spectrum even if you want. “Whatever you want to eat, just look around and choose whatever you want.”
With a wave of his hand, it's really not lavish. The upper limit of this place is just like that.
"Let's have hot pot." Han Ci scanned the restaurants at the entrance of the mall and found nothing special. "In this freezing weather, the wind is biting, but this hot pot is the only one that still has some warmth."
"Han Feng Ci Gu, right? I found that your name and person actually have a bit of literary feel in your bones. Did you originally want to be a literary girl?"
"That's right, it's just a pity. I don't have any talent." Han Ci curled his lips, "In life, there are nine out of ten people who are not going as they wish. You have already gotten used to it."
"How poor you are." After a short time of contact, this girl started to talk a lot. She seemed to be a guy who was cold on the outside and hot on the inside. Meng Fanqi smiled and said, "Why are you so cold usually? Aren't you tired of carrying it?"
"It's not that I'm just pretending, but most of the time I'm really not interested in other things. I don't understand what others like, and they don't understand what I say. If they are already different, why bother to forcefully integrate?"
Han Ci shook her head, mainly because she didn't feel the need to waste this time. "I actually think that if you have to live in a way that others think is good and normal, then that's carrying it. You don't want to, but you have to force yourself to do it. Isn't that carrying it?"
At this point, the waiter came up with the bottom of the pot.
Han Ci pointed at the back of the leaving waiter and said, "Only holding it this way makes sense."
Meng Fanqi originally only thought that this girl was cold. Although she was delicate and beautiful, she always gave people the feeling that she could only be seen from a distance. Now that I see her talking nonsense in a serious manner, I suddenly find it particularly interesting.
Since coming back, I have actually not had much campus life. After only staying in school for a few days, I eagerly skipped classes and squatted in the library and rented houses busy preparing and implementing these algorithms.
Now this feeling is a bit youthful.
Meng Fanqi recalled the past half year in his previous life, when he was busy chasing a senior from the next door courtyard.
My senior sister, who was two years older than me and was about to graduate from her undergraduate degree, rejected Meng Fanqi straight away.
But he didn't believe in evil. He got up early all day long to buy breakfast for others in the cafeteria, and often squatted near the dormitory building to greet them.
"Young and ignorant little boys always like to be lickers." Meng Fanqi recalled it and felt very sad.
I spent a lot of effort trying to catch him, but in the end we didn't even get along with him for a few days. In terms of appearance, that senior sister is still two levels worse than the one in front of me.
But I saw Han Ci twice, and even went out to eat and chat alone today, but I didn't even think about it at all.
"Maybe this is careerism." Meng Fanqi silently praised himself in his heart, "Girlfriends and other things will only slow down my code writing speed!"
"What are you thinking about? Why don't you hurry up and eat?" While Meng Fanqi was stunned, Han Ci was already peeing in his belly, he was in a hurry, his technique was very standard, "I'm Beijing'er Jing'er Erbajiang'er, this is called a Authentic."
Listening to Han Ci's poor Beijing accent and Erhua accent, Meng Fanqi finally couldn't hold it back and laughed out loud.
Han Ci looked at him innocently, as if he didn't understand what was so funny about this.
"So let's talk about it, people are actually a bit like hot pot ingredients." Meng Fanqi picked up the previous topic again, "When you see other ingredients, you throw them in. Either you can't go in and cook them, or if you cook them for a long time, it may not be good. eat."
"That makes sense." Han Ci said, having almost finished half a plate of tripe. "I'm just like this tripe. I can't boil it with other ingredients, so I don't have to join in the fun. It’s better to cook this tripe as early as possible, it will be more tender and delicious. If it has to be piled with other ingredients, no one will like to eat it if it gets too hot.”
