Huayu: I'm reborn, but you still force me to be a scumbag?

Chapter 609 Deep Adaptive Recommendation Networks Based on Temporal Context
"It's done? What's done? What's this person saying?"

Upon seeing the message from Liu Qi, Chen Nuo was immediately filled with three question marks.

He stared at the words on his phone screen, remaining silent for a long time.

At the same time, he thought he might be imagining things, but he thought he heard someone singing "Hallelujah~ Hallelujah~" behind him.

He looked back, but there was nothing behind him, just emptiness.

Tong Liya was startled by his action. "Honey, what's wrong?"

Chen Nuo was a little dazed. After a couple of seconds, he shook his head and said, "It's nothing. I must be overthinking it."

Tong Liya's expression became even more curious, and she looked at him cautiously, asking, "Honey, what are you looking at? Can I see?"

Chen Nuo laughed and said, "Go ahead and look." Then he handed her his phone.

Tong Liya looked at her phone.

Although it was almost noon, the room was still dark with the curtains drawn and the lights off. The light from her phone screen reflected off her face, making her eyes look bright.

Chen Nuo looked at the woman, but his thoughts inexplicably wandered a hundred and eight thousand miles away.

He recalled a conversation he had a few days earlier on a Silicon Valley night with one of the world's most successful tech investors.

is it possible?
Peter Thiel gathered a group of Ivy League elites and struggled for more than two years, but they couldn't get anything done. Is it really possible that a group of Peking University students will make progress on this?
Damn it, this...

Chen Pingguo, who was obsessed with foreign things, initially thought it was impossible, but then she thought, "Wasn't it the same in my past life?"
Although he wasn't sure exactly how much effort Facebook had put in back then, he was willing to bet that the giant's initial investment was far beyond what Peter Thiel's small elite team could match now.

But what happened in the end?

Compared to Reels, which is supposed to be a direct copy of Yangdou's Reels, it's laughable. Not only is it a complete copy from start to finish, but everyone who's used it says it's terrible.

Thinking of this, Chen Nuo suddenly came to his senses.

What is Zhang Yimi doing now?

Is it really possible to skip Zhang Yimi and have Liu Qi, this brilliant strategist, lead a team to create something?

He's a terrible actor in this life, and in his past life he was an even more foolish internet celebrity. He really doesn't understand anything.

Clearly, he wasn't the only one in the room who was acting foolish.

Tong Liya looked at the messages over and over, then looked at him with clear eyes and asked, "Honey, what is computing power?"

Chen Nuo thought for a moment and said, "Computing power is... well, the ability to calculate."

"Aren't there enough computers? Why spend money to buy servers?" Tong Liya blinked curiously. "What exactly did this person come up with?"

"Well—I'm a little sleepy, I'm going to sleep now."

Chen Nuo didn't sleep well that night.

It wasn't because the cool, smooth silk duvet cover was uncomfortable, nor did he have any strange habit of not being able to sleep in a particular bed; it was simply because he slept very restlessly and had many bizarre and fantastical dreams.

When he woke up, he couldn't remember any of his dreams.

He rubbed his eyes and saw Tong Liya sitting by the French windows in the bedroom, on a large and comfortable off-white fabric couch, using a laptop to browse the internet.

"What time is it?" he asked.

When Tong Liya saw that he was awake, she said in surprise, "It's only 2 o'clock, why are you awake? Do you want to sleep a little longer?"

2 o'clock. That means he only slept for a little over two hours.

Chen Nuo paused for a moment, then threw back the covers, got out of bed, and said, "Never mind, I'm not going to sleep. Is your car here? Can I borrow it for a bit? I need to take care of something."

In this situation, other women might have asked a few questions, or even flirted a little, but Tong Liya didn't say a word. She simply handed him the keys to her Jeep SUV and led him to the car parked on the roadside outside.

"gone."

"it is good."

Chen Nuo stepped on the gas and drove off.

Looking in the rearview mirror, I saw Tong Liya standing still, staring in this direction.

Sigh, with a woman like that at home, how could anyone bear not to go home?
……

E-Tech's offices are located in Zhongguancun.

It's less than a kilometer from the south gate of Peking University.

This region has been known as China's Silicon Valley since the 1990s.

Although Chen Nuo was a complete novice in the tech world, he had heard plenty of boasts. He knew that this was the place where established giants like Baidu, Lenovo, and JD.com had risen to prominence. He also knew that in the future, new empires like Xiaomi, ByteDance, and Meituan would emerge.

However, these things were all quite distant for him, a complete novice.

He's incredibly excited right now, and the reason he can't even sleep is because he's really, really curious.

That's how he is.

But for the dozens of Yike employees who were just coming to work on an ordinary workday, the sudden notification half an hour earlier that their legendary behind-the-scenes boss, who had never shown his face in years, would be coming to inspect the company today was shocking.

Almost instantly, the once orderly office area was thrown into chaos, like a chicken coop that had been hit by a firecracker.

"Who, who wants to come?"

"Impossible! Who told you that?"

"President Qi just made the call!"

"No way, is Chen Nuo really coming?"

"I know, it must be for the live streaming platform we're going to launch in a few days!"

"Hey, have some self-respect, will you? Can you stop embarrassing Peking University?"

"Shut up, I think you were the one who jumped the highest just now!"

"Do you think we can get an autograph later?"

"That's not a good idea, they're all from the same company..."

"It's from the same company. They never showed their face when they donated money. I've been working at the company with Senior Liu Qi for three years, and this is the first time I've seen them. Where did this company come from?"

"What did President Qi say? Should we all form a human wall at the elevator entrance? What if we get spotted?"

"What can we do? Let's all enjoy the limelight together."

"Haha, I told my friend last time that our boss is Chen Nuo, and she didn't believe me. I really want to call her and ask her to come and see for herself."

"Is that the girl you're chasing now? I advise you to give up. Haven't you heard the saying that meeting Brother Nuo can ruin your life? If you call her over, you might end up losing both your money and your heart."

"Makes sense."

Amidst the cacophony of opinions, a girl with a ponytail stepped forward and said, "Alright, everyone, quiet down. I know you're all very excited right now, and so am I. I believe that we all grew up watching Mr. Chen's movies..."

"Ha ha ha ha."

A burst of laughter immediately filled the office area.

The girl laughed along, then her smile faded as she said, "But once we get to the company, when we're at work, we'll be colleagues with Mr. Chen, not idols and fans. So, I hope everyone will stay calm and not let Mr. Chen think we're useless. Losing face for Peking University is a small matter, but losing face for ourselves is a big deal."

"Hahahahahaha."

The group laughed again.

After laughing, they all sat back down and got back to their own tasks.

But what they didn't know was that at that moment, right outside the company office door, out of their sight, two people were already standing there, listening quietly for a while.

Chen Nuo asked, "Is this the Li Wenwen you were talking about?"

Qi Yuntian said, "That's right. She's the only Chinese literature major here, and she's currently in charge of the company's administration. I didn't hire her; she was recommended by a professor from Peking University. She used to be the vice president of the Peking University Student Union and is currently a graduate student. She came to our company for an internship. I talked to her before, and she plans to take the civil service exam after graduating with her master's degree next year."

Chen Nuo nodded. This was indeed the current predicament of Yike Company.

This company was just a hobby he created to get shares in Facebook. Even the name wasn't original, which shows he never intended to use it long-term.

In recent years, this place has become more of an internship and entrepreneurship base in cooperation with Peking University than a company. Most of the people here are part-time students. They are called employees, but they are actually just here for internships. Under such circumstances, the turnover rate is quite high. It can be said that over the years, apart from Liu Qi who has been here and received a salary of several thousand yuan without changing, most of the other people have been replaced.

Whether this situation needs to be changed, and how it should be changed, depends on the outcome of his conversation with Liu Qi today.

……

"Hey Chen Nuo, long time no see! Why haven't you replied to my QQ messages? Hey, have you gotten shorter?"

When Chen Nuo first saw Liu Qi, his intelligent face, unchanged over the past eight years and now noticeably heavier, made him want to run away. When he heard those words, he wanted to slap himself, thinking he must have gone mad, dreaming too much and hallucinating.

However, he glanced back at the closed conference room door, muttered to himself, "Since I'm already here," and then smiled, saying, "I haven't shrunk; you've probably grown taller. Are you 1.7 meters tall now?"

Liu Qi shook his head and said, "No, it's still 0.5 centimeters short. I haven't grown taller since I was 17 and a half. But if I wear today's shoes, I'll be 171.5 centimeters tall, and if I wear another pair, I'll be 172.2 centimeters tall."

Chen Nuo gave a thumbs up and said, "No wonder you think I'm short, it turns out your shoes are too high."

Liu Qi tilted his head and thought for a moment, then chuckled and said, "You're right, Chen Nuo, you've become smarter."

"Heh." Chen Nuo forced himself to endure it. He had to admit that this feeling was at least five times harder than his mother wearing a mask and acting out the love and hate of a remnant of the Taiping Heavenly Kingdom!
"Alright, let's get down to business." He forced a smile and said, "What happened with what you told me on QQ? Could you tell me about it?"

“Okay,” Liu Qi immediately agreed.

Chen Nuo breathed a sigh of relief. It seemed that this person was still communicable. He immediately smiled and said, "Alright, then please tell me and President Qi about your results in detail."

"it is good!"

Liu Qi readily agreed, then stood up with a beaming smile, walked to the whiteboard, picked up a pen, and immediately began writing on the board with a snap, saying as he wrote: "!@#￥！#￥！#@！%@"

After listening for less than a minute, Chen Nuo felt nauseous. "Stop, stop, stop!"

Liu Qi stopped immediately.

Chen Nuo asked, "What are you speaking? Chinese?"

Liu Qi thought for a moment and said, "What I just said was over 70% Chinese, so it should be Chinese. What's wrong, Chen Nuo?"

“I…” Chen Nuo took a deep breath and said, “Could you put it simply?”

Liu Qi asked in surprise, "Didn't you just ask me to explain in detail?"

"...Um, I've changed my mind, is that okay?"

“It’s possible.” Liu Qi looked at him, then suddenly sighed and said, “Chen Nuo, you’re really hard to please. No wonder I’ve seen so many people online saying you like to act like a big shot. Chen Nuo, you can’t do this, you won’t make any friends.”

At this moment, Chen Nuo really felt like a million ants were crawling all over his body. He wanted to stand up, tear his clothes apart, and scream. In the end, he held back, but he really couldn't laugh anymore. He looked at Liu Qi seriously and said, "Please tell me, I'm begging you."

……

"...Then I discovered that the recommendation systems of these video websites and social platforms on the market are all problematic."

"They are all still using traditional 'matrix factorization' and 'item-based collaborative filtering,' with algorithms that converge at an alarmingly slow speed, and recommendation logic that relies solely on tags to determine content."

He wrote a few large characters on the whiteboard, then turned around and said:

"Based on what you said before, Chen Nuo, I have developed a new algorithm. I call it the Temporal Context-Based Deep Adaptive Recommendation Network, or CADAN for short."

"The core idea is actually very simple: to use high-dimensional tensors to model the data from the three dimensions of user behavior, timestamps, and content tags."

"...Do you want me to explain it simply again? Sigh, Chen Nuo, but if it's too simple, I won't be able to explain it clearly."

"Okay, well. Let me think about how to put it. Well, roughly and not exactly, what I want to do is to let the system learn to determine what people like. Every time a user swipes, pauses, or clicks, it generates a signal, a set of parameter changes. And the AI ​​has to learn it in real time, recalculating every second."

As Liu Qi spoke, he began to draw a diagram, a network diagram resembling neurons, with densely packed lines.

"Therefore, I used convolutional neural networks to identify video frame images, recurrent neural networks to analyze user behavior sequences, and then fused the two into a weighted model. In this way, the system not only knows what the video is, but can also predict in advance what the next user might want to watch!"

Then, when things got to this point, I completely understood, Chen Nuo, do you know that?

This is essentially self-learning!

The algorithm I developed can already run a small sample model on my laptop.

Next, with more computing power and user data, I can make it watch videos like a human, remember user preferences, and proactively recommend content to everyone. This will achieve the effect you mentioned earlier, allowing everyone to see what they like to watch!

After Liu Qi finished speaking, the conference room fell into a brief silence.

Qi Yuntian looked at Chen Nuo, then at Liu Qi, and suddenly smiled, "Well, thank you, Liu. Why don't you go out for a bit so I can talk to President Chen?"

Liu Qi shook his head and said, "I haven't finished speaking yet."

He walked over, opened his laptop on the table, and the screen lit up with a dense array of code and diagrams.

He pushed the computer towards Chen Nuo and said, "This is the small sample model I ran on my laptop, a prototype system that can learn and predict user behavior in real time. It's very simple; this one line of code is..."

"Hey, Xiao Liu, just leave the notebook here, we'll figure it out ourselves," Qi Yuntian said with a smile. "It's so simple, no need for you to explain it."

Liu Qi said "Oh," and then said, "Alright then. I'll go out now."

After Liu Qi left the meeting room and closed the door.

Qi Yuntian turned around, moved the mouse on the laptop, then closed it and asked, "Do you believe him?"

Chen Nuo frowned slightly and said, "I don't know."

"Why? Isn't it what you want?"

"It sounds similar, but I don't know for sure."

Qi Yuntian asked in surprise, "Why don't you know? Didn't they explain it very clearly just now? It's so simple, how could you not know?"

Chen Nuo nodded and said, "Yes, it's quite simple. Why don't you repeat it again?"

"Fine, let's restate it. It's a deep adaptive recommendation network based on temporal context, or CADRN for short. How about that?"

"Impressive. Then explain what you mean."

"I've repeated it; now it's your turn to explain. Why don't you explain?"

"Okay, I'll explain. It really just comes down to two words: awesome. What do you think?"

"I think it's good," Qi Yuntian said seriously.

Then, the two of them burst into laughter.

Qi Yuntian laughed and shook his head, saying, "I've lived for over 30 years, and this is the first time I've ever felt like an idiot."

Chen Nuo said, "This fully demonstrates that Georgetown still lags behind Peking University."

Qi Yuntian said, "Yes, that's right. It's probably on par with the Beijing Film Academy."

"more or less."

After Chen Nuo finished speaking seriously, the two of them laughed together again.

After laughing for a while, Qi Yuntian asked, "So, are you really going to do it?"

Chen Nuo hummed in agreement.

Qi Yuntian said, "Seriously, what do we do now? Although I don't understand it, it sounds quite plausible. Should I ask my dad to have a few academicians or professors verify it? After all, according to him, the follow-up is quite troublesome and will cost a lot of money. Shouldn't you be more cautious?"

This time, Chen Nuo didn't reply and thought for a full five minutes.

Five minutes later, he finally let out a breath and said, "Let's forget about the verification. This isn't a good time for too many people to know. Besides, trust those you employ, and don't employ those you don't trust. I've known him for eight years, and based on my understanding of him, if this was a trap he set for me, then frankly, I'll accept it. Go and call him in. Oh, and Li Wenwen too, call her in as well."

Qi Yuntian wasn't surprised; he just smiled and said, "Didn't you just say you didn't want too many people to know?"

"Hey, she's a liberal arts student, what does she understand?"
