"Huh?" Han Ci couldn't believe her eyes. She had a rare chance to meet with her teacher last time and discussed some topics in detail. Even President Fu didn't tell her about the preliminary direction they discussed with Academician E Wei'nan. But this guy with average mathematical skills guessed it right by seventy to eighty percent?

Meng Fanqi could tell what this girl was thinking just by looking at her expression. "Buddy, my math skills may be average, but these residual ideas and related experiments were all done by me. Do you really think I know nothing?"

"Is that so? Are you for real?" To be fair, Han Ci had seen geniuses her age before. But what made it remarkable was the contrast between expectations and reality. If someone who was also a mathematical genius said it, it wouldn't be surprising to Han Ci, even if they were underage.

But hearing such accurate guesses from someone like Meng Fanqi, whose mathematical and physical skills were average, made Han Ci start to become curious about this person.

"Well then, Meng, tell me about your ideas." Han Ci thought to herself that this might be a good thing. Although Meng might not fully understand it, as an author, his understanding would naturally be deeper and more insightful than most people.

Since he could guess her thoughts, it would be interesting to see what insights he had.

"This perspective is to view the entire network as a dynamic system. It is said that neural networks are black boxes, and no one knows what they are really doing inside." Meng Fanqi recalled that Academician E Wei'nan's main viewpoint in this regard was from the perspective of dynamic systems.

"If we view the problem from this perspective, we can include the designs of many network structures, which can be considered as a broad-minded approach. From this angle, you can categorize my residual ideas as a small branch of theory." Meng Fanqi smiled.

His innovation seemed to have caught Academician E Wei'nan's attention in advance, prompting him to propose related speculations and ideas earlier.

"A dynamic system is a bridge. By using your residual ideas and the equivalence of dynamic system states, you can introduce many concepts from the fields of mathematics and physics to explain many phenomena." Han Ci didn't think about incorporating other people's methods.

She was more curious about why this method was so powerful, with significant performance improvements for two consecutive years, almost surpassing the progress of the past few decades.

"By looking forward, you can explain many problems and phenomena. By looking backward, you can design networks based on theories and be more greedy. However, neural networks involve repeated transformations in many dimensions. If you purely use this method to answer questions, you can only stay at the level of toy-like networks and data."

"That's true... Once you design multiple dimensions of repeated transformations, analysis becomes extremely difficult."

"The dark clouds that obscured the deep learning sky have been dispelled by me, and the dark clouds that obscure the interpretable theory will depend on you." Meng Fanqi's words, aside from joking, could also be considered a sincere blessing.

Leading Han Ci to a small shopping mall near the school.

Outside the Fifth Ring Road, the level of consumption couldn't go any higher. "What do you want to eat? Just choose whatever you like."

With a wave of his hand, it wasn't really extravagant, and the upper limit of this place was just like that.

"Let's have hot pot." Han Ci scanned the restaurants near the mall entrance and didn't feel anything special. "In this cold weather, with the bone-chilling wind, only hot pot can provide some warmth."

"Ah, so you're a fan of Han-style poetry. I found that both your name and your personality have a touch of literary feeling. Were you trying to be a literary girl back then?"

"Kind of, but it's a pity I didn't have much talent." Han Ci pouted. "In life, eight or nine out of ten things don't go as you wish. I've gotten used to it."

"You're really good at self-deprecating." They hadn't known each other for long, but this girl's words had increased. It seemed that she was a cold person on the outside but warm on the inside. Meng Fanqi smiled and said, "Why are you so cold most of the time? Isn't it tiring to keep up that facade?"

"It's not about keeping up a facade, 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 we're already different, why force ourselves to fit in?"

Han Ci shook her head. She mainly didn't think it was necessary to waste this time. "I actually think that if you have to live in a way that others think is good and normal, that's when you're keeping up a facade. If you don't want to do it but still force yourself to do it, isn't that keeping up a facade?"

As she said this, the waiter came over with the pot.

Han Ci pointed to the departing waiter and said, "Only this kind of facade has some meaning."

Meng Fanqi originally thought this girl was cold, although she was beautiful, she gave off a feeling of being unapproachable. But now, seeing her talk seriously and randomly, he suddenly found it very interesting.

Since coming back, he hadn't really experienced campus life. He only stayed at school for a few days and then hurriedly skipped class to prepare and implement these algorithms in the library and rented house.

Now, this feeling finally had a taste of youth.

Meng Fanqi recalled the past half year of his previous life. At that time, he was busy pursuing a senior sister from the neighboring department.

The senior sister was two years older than him and was about to graduate from her undergraduate studies. She directly rejected Meng Fanqi.

But he didn't believe in superstition and would wake up early every day to buy breakfast for her, running errands for her, often squatting near the dormitory building.

"Young and ignorant little boy, always being a lapdog." Meng Fanqi reminisced and felt a sense of melancholy.Back then, he had put in a lot of effort to win her over, but in the end, they didn't spend much time together. That Senior Sister, in terms of appearance, was a couple of notches below the woman in front of him.

Yet, he had met Han Ci twice, even had dinner and a chat with her today, but he hadn't harbored any intentions from start to finish.

"Perhaps this is what being career-minded is," Meng Fanqi silently praised himself in his heart, "Having a girlfriend would only slow down my coding speed!"

"What are you thinking about? Why aren't you eating?" Just as Meng Fanqi was lost in thought, Han Ci was already cooking tripe. Her movements were standard, "Old Beijing's twenty-eight sauce, this is so authentic."

Listening to Han Ci's clumsy Beijing accent and retroflex final, Meng Fanqi couldn't help but laugh.

Han Ci looked at him with an innocent face, seemingly not understanding what was so funny.

"So, people are a bit like hot pot ingredients," Meng Fanqi picked up the previous topic, "Seeing other ingredients and seasonings being added, it's not that I can't join in, but if I'm cooked for too long, it might not taste good."

"That's an interesting way to put it," Han Ci said, almost finishing half a plate of tripe, "I'm like this tripe, not needing to mix with other ingredients. There's no need to join in the hustle and bustle. This tripe is better when it's cooked just right, tender and delicious. If it's overcooked with other ingredients, no one would want to eat it."
