After rebirth, I rejected the school beauty and Qingmei

Chapter 148 What on earth am I planning? (Second update please subscribe)
What am I excited about?
Of course I want to go back to the hotel with you early!
Then we will...

Uh……

Excited.

I forgot that Toffee is still drinking brown sugar water these days.

For a moment, Chen Yu didn't know how to explain it, his mind was racing.

At this time, Xia Naitang asked: "Didn't you go to see the venture capital today? Why are you back so early?"

Seeing Toffee take the initiative to change the topic, Chen Yu smiled and replied: "Teacher Xia, not only did I meet with all the venture capital investors today, but I also received investment. Guess how many?"

Xia Naitang just shook his head slightly, with a calm expression: "I don't know."

She is not very interested in money.

The salary and bonus can fully meet her material needs in life.

Chen Yu huffed and explained: "I raised 40% of the shares of Zhifu, and received a total investment of 6500 million."

Xia Naitang calmly said softly: "Go back, I'm hungry."

Chen Yu nodded.

Along the way, he always held Toffee's snow-white, tender and boneless hand.

Never let go.

This also caused Chen Yu and Toffee to receive a lot of envious and jealous looks.

The man was jealous that Chen Yu had such a beautiful girlfriend with a great figure.

The woman, on the other hand, is thinking about how to find such a handsome boyfriend!

Chen Yu didn't care at all about these looks.

He even tentatively inserted his fingers into Toffee's fingers, thinking of interlocking with hers.

Unexpectedly, Xia Naitang just frowned slightly, but kept looking forward, and did not stop any of Chen Yu's movements.

In this way, the two of them linked their fingers and strolled under the afterglow of the sunset until they returned to the hotel.

……

The night is getting darker.

After dinner, Chen Yu and Xia Naitang returned to the hotel room.

"Teacher Xia, you go take a bath first, and I'll make you some brown sugar water."

"Ah."

Toffee nodded slightly, and then she opened her suitcase and prepared to take out a set of home pajamas.

But as soon as she opened the box, she noticed something was wrong inside.

Why is there a pink silk suspender nightgown in my suitcase?
And a pair of black stockings?
Who did this? !

She frowned and turned around to look at Chen Yu, who was boiling brown sugar water.

Don't even think about it!
He must have put these things there!
Xia Naitang had a gloomy and pretty face. She held up her nightgown and stockings and asked, "Chen Yu, can you explain to me what's going on with these two things?"

Chen Yu had been prepared for a long time. His eyes were as clear as water and he showed a pure and innocent smile: "Teacher Xia, don't I have to go back to Jincheng tomorrow and the day after tomorrow? I bought some Yanjing specialties for my aunt."

"You call suspender nightdress and silk stockings specialties of Yanjing?" Xia Naitang looked at him in disbelief, "Also, do you think it's appropriate for you to buy these things for your aunt?"

Chen Yu looked frank: "It's suitable! Very suitable! I was raised by my aunt, and the relationship between me and her has long been inseparable."

Xia Naitang's red lips trembled slightly, speechless.

What kind of aunt is this? !

You actually asked your nephew to buy stockings for you?
She stopped arguing and just ordered: "Put the things you bought for your aunt back into your suitcase!"

Chen Yu shrugged: "My suitcase is full and I can't put it in."

"What did you buy?"

"It's just suspender nightgown and stockings. It's already full."

"........."

Xia Naitang was speechless: "Why did you buy so many nightgowns and stockings for your aunt?"

“Mr.

"The quality is not good and it will break if you tear it lightly? Then why did you buy so many?"

Chen Yu shrugged: "I don't know, my aunt told me to buy it, so I just bought it."

"Oh~"

“Mr.

Xia Naitang was startled, her face flushed slightly, and then she said angrily: "Impossible! I won't wear such immoral things!"

Chen Yu snorted, sighed softly, and said gently: "Teacher Xia, how is this immoral? Isn't it just like high heels, which are just to make women look more beautiful?"

"Different!"

"Why is it different? Everyone dresses like this now. It's because your ideas are too conservative."

"..."

Xia Naitang frowned, said nothing, and stared at Chen Yu.

Chen Yuyun said calmly: "Teacher Xia, sometimes I wonder, are you really a person who has received Western higher education? It's already 2023, why are you still talking to people who lived in the Qing Dynasty? Like, why are you so conservative in your thinking?"

Xia Naitang narrowed her almond-shaped eyes and asked suspiciously: "2023?"

Chen Yu snorted: "Slip of the tongue, 2009."

Xia Naitang felt very strange. No matter how he misspoke, he wouldn't say 2009 as 2023, right?
But Chen Yu quickly interrupted her train of thought: "Toffee, actually I'm also looking forward to seeing how you look in a silk suspender nightgown and stockings. I think you must be beautiful."

Listening to the infinite longing and longing in Chen Yu's gentle tone, Xia Naitang frowned and pondered for a while.

When Chen Yu saw that she hadn't spoken for a long time, he no longer made things difficult for her, and everything had to be done step by step.

He turned around, faced the induction cooker and the white steel basin, and boiled brown sugar water.

Xia Naitang raised her head and looked at Chen Yu's back with complicated eyes. She gritted her teeth and whispered: "Anyway, I will definitely not wear this."

This sentence was not loud, but Chen Yu heard it clearly. He shrugged without looking back.

"Teacher Xia, you should take a shower first."

"Hmm~"

After a while, Chen Yu heard the sound of the bathroom door closing.

The corners of his mouth curled up slightly, and he shook his head and smiled.

And when Chen Yu boiled the brown sugar water and put it in a bowl, he turned around and found a pair of black silk threads lying alone on his bed.

Chen Yu glanced around, but he didn't notice the pink silk suspender nightgown that he bought specifically for Toffee.

Could it be that……

Toffee was persuaded by me?
Is she going to try on that suspender nightgown?
Chen Yu was overjoyed. In his previous life, he had never seen Toffee wearing a silk suspender!
……

Chen Yu rarely felt that his days were like years, but during the half hour he was waiting for Toffee to come out of the bath.

He felt as if he had been waiting for half a lifetime.

creak.

The bathroom door was opened.

Xia Naitang put on a silk suspender nightgown and walked out, as pure and moving as a hibiscus emerging from water.

Chen Yu cast his eyes on her, and saw that Xia EE at this moment did not have her usual high ponytail, and her black hair fell down like a waterfall on her shoulders.

Under a pair of curved willow eyebrows, there is an indescribable shyness hidden in the almond-shaped eyes that seem to hide silver stars.

The eyebrows are darkened by the spring mountains, and the autumn water cuts the pupils...

Xia Naitang just pursed her red lips lightly and raised her eyes to look at Chen Yu, making him feel that Toffee's body was exuding countless kinds of amorous feelings.

And that beautiful figure...

Uh……

Chen Yu glanced around and discovered that Xia Naitang was actually covering her chest with a sports T-shirt!
Chen Yu only felt his scalp numb!

Teacher Xia, can you stop being so conservative?

A hint of disappointment flashed in Chen Yu's eyes.

I sighed in my heart.

He forced out an innocent smile: "Teacher Xia, please sit on the bed first, and I'll feed you brown sugar water."

Xia Naitang's face turned red and she hummed slightly.

Immediately, she sat on the bedside, put the T-shirt aside, and wrapped herself tightly in the quilt.

Chen Yu looked at this scene and thought, wouldn't your nightgown be in vain?

Might as well just wear pajamas.

Hey……

Chen Yu sat on the edge of the bed and fed Xia Naitang spoonful after spoonful.

This time, she was still very cooperative.

Not even biting the spoon again.

Not as cute as a little tiger.

Chen Yu looked at her with a smile and asked, "Teacher Xia, why are you so good tonight?"

Xia Naitang was stunned for a moment, staring at the position of her feet. After thinking for a while, she whispered: "I don't know."

Chen Yu fed him another spoonful: "Open your mouth."

"Ah~"

"Teacher Xia, you are so cute like this."

"Hmm~"

"I really like you..." When Chen Yu said this, he saw Xia EE's face change suddenly, and he quickly added, "I really like your cute look."

Xia Naitang looked up at him, was silent for a few seconds, and said softly: "Really?"

"Well, really."

"Didn't lie to me?"

"I really didn't lie to you."

Seeing Chen Yu's vow, she nodded slightly and let out a soft "hmm" in her throat.

It wasn't until Chen Yu finished feeding her the brown sugar water that Xia Naitang said, "Chen Yu, I have something I want to discuss with you."

Chen Yu was sitting on the edge of his bed, holding his laptop and typing codes.

He said casually: "Teacher Xia, if anything happens, just tell me."

Xia Naitang hesitated for a moment: "I want to ask you, have you ever thought about adding a recommendation algorithm to the 'Knowledge' website you are building? Recommend content that users are interested in to them."

Chen Yu suddenly stopped what he was doing and turned his head to look at her, his eyes slightly pointed.

This look made Xia Naitang's heart tremble slightly.

For some reason, she was a little scared.Just like when I was a child, I said something wrong and was scrutinized by my mother's eyes.

This made her suddenly regret.

The "Zhifu" project has a valuation of over [-] million and will become Chen Yu's core business in the future.

I am... not familiar with him.

How could he possibly allow himself to be involved?

As mentioned before by Shu Yi and Qiao Yun, data mining will involve the commercial secrets of Internet companies.

How could anyone risk leaking secrets and cooperate with outsiders?

But at this moment, Chen Yu slightly raised the corner of his mouth and said easily: "Teacher Xia, how do you know that I am writing the code for the recommendation algorithm?"

"what?"

Xia Naitang was stunned for a moment, and she asked doubtfully: "Do you understand the recommendation algorithm? Your website has not been online yet, and you have not done any data mining, so you just wrote the code for the recommendation algorithm?"

Chen Yu nodded: "Yes, isn't it an intelligent recommendation algorithm? I've already figured it out."

Xia Naitang opened her mouth slightly when she saw Chen Yu lifting his weight with ease and confidence.

She thought this was incredible.

This guy has already solved a cutting-edge field topic that he is still researching?

He's not lying to me, is he?

Will not.

Although this little guy is a bit of a pervert, he won’t lie to me!

Chen Yu smiled: "Teacher Xia, do you want to learn? I'll teach you."

"you teach me?"

"Yes. Isn't it possible?"

Toffee frowned her beautiful eyebrows and fell into a brief moment of deep thought and entanglement.

But soon, Chen Yu shook his head and said: "Disciples don't have to be inferior to their teachers, and teachers don't have to be better than their disciples. There is a priority in learning the Tao, and there is a specialization in skills, that's all."

This sentence made Xia Naitang let go of her aloofness. She lightly opened her red lips and said, "How did you do it?"

Chen Yu hooked his fingers and said with a smile: "Come here, I will teach you."

Without thinking, Xia Naitang stood up and walked to Chen Yu's bedside, holding the quilt in her arms, and immediately sat on the head of his bed.

Toffee did not forget to cover herself tightly.

"Okay, you can teach me."

Chen Yu glanced twice, but couldn't see anything.

He was speechless for a while: "..."

What am I planning? !
But looking at Toffee who was obsessed with academics, Chen Yu still explained to her a fusion solution based on GBDT (Gradient Boosting Decision Tree, an iterative decision tree algorithm) + LR (Logistic Regression Classification Algorithm) in a professional manner.

This is a recommendation algorithm model proposed by Facebook in 2014, which has had a great influence on the Internet field in later generations.

It can be said that since the advent of the GBDT+LR fusion solution, the recommendation algorithm has entered the stage of feature engineering modeling.

That is, the screening and construction of features are completed by the model, and the entire recommendation system becomes an end-to-end full-link system.

In addition, GBDT can perform high-order crossover of feature dimensions very well, which is absolutely impossible for the most advanced FM model in 09.

After Chen Yu's one-on-one, step-by-step explanation and teaching, Xia Naitang felt that a whole new world had opened up.

What this little guy just explained is enough to write an epoch-making paper and submit it to the top journal in the field of computer science, "Journal of the Association for Computing Machinery"!

Xia Naitang was shocked beyond measure by Chen Yu.

She looked at him in shock: "How did you come up with this?"

Chen Yu said easily: "Mr. Xia, didn't I say it before? I have a lot of magical inspirations in my mind. As long as I inspire them and write them casually, they will be papers at the top international journals and conferences. "

Xia Naitang didn't have any doubt at this moment and believed Chen Yu one thousand percent.

She was a little excited, grabbed Chen Yu's arm with both hands, and shook it: "Then hurry up and inspire all your ideas!"

"Why inspire it?"

"Go to the stars and the sea for the sake of human civilization."

"Uh... I don't have that big ambition." Chen Yu shook his head helplessly, "Besides, it is very difficult to inspire."

Xia Naitang was stunned.

Is it difficult to inspire?

She was confused and didn’t understand the meaning of this sentence, so she asked: “Then how can I inspire you?”

Chen Yu hesitated: "It's better not to say anything."

Xia Naitang frowned: "I must say it!"

"This……"

"Say it!"

Chen Yu hesitated: "Teacher Xia, are you sure you want to listen?"

Toffee couldn't wait any longer. She nodded heavily: "OK!"

"Then after listening to this, you can't be angry, hit me, scold me or yell at me."

"…………,I promise you."

"Come here with your ears, and I'll tell you."

When Xia Naitang heard this, she suddenly had a bad premonition, because Zhou Shuyi also said this today.

Then, it made her blush for a long time!
But curiosity, coupled with a love of academics.

Still drove Xia Naitang to come over...

Chen Yu whispered softly in her ear...

30 seconds later.

Xia Naitang was shocked on the spot. At the same time, her pretty face turned red, spreading from her delicate face to her neck and behind her ears.

As if painted with a layer of crimson paint...

She backed away continuously and reached the edge of the bed, almost falling to the ground.

Fortunately, at the critical moment, Chen Yu caught her in time: "Teacher Xia, are you okay?"

Xia Naitang threw his hand away, hugged the quilt, and quickly hid in her bed.

Cover yourself with the quilt and cover yourself tightly.

She only showed one pair of eyes, but she was furious: "Chen Yu! You, you, you!!! You are so disgusting!!!"

Chen Yu was helpless: "Teacher Xia, I didn't want to say it in the first place, but you insisted on me. And you also promised me not to be angry, not to hit me, scold me, or yell at me..."

Xia Naitang gritted her teeth and looked disgusted: "Bah! Disgusting! Just one sentence, you are so disgusting!"

She never expected that Chen Yu's way of inspiring inspiration would be...

what! ! !
I feel sick just thinking about it! ! !

After saying that, Xia Naitang covered her head with the quilt, motionless and silent.

Chen Yu felt incredible when he saw this scene.

Toffee actually just scolded me!
It's so much better than getting a beating yourself!
His courage suddenly became much greater, and he said shamelessly: "Teacher Xia, I really didn't lie to you. If you need my inspiration one day, I will be waiting for you at any time."

"Bah! Disgusting! Chen Yu, you are not allowed to speak!" Xia Naitang's female voice came from the bed and fell into Chen Yu's ears.

But it sounded mixed with a little choking sound.

No way……

Are you just making me cry?
Chen Yu thought, Toffee's face was still too thin.

After all, she had never seen such a shameless person like me before she met me!
He smiled and said: "Toffee, what I just told you, you can write a paper and send it to a journal."

Seeing that Xia Naitang hadn't come out yet, he said seductively: "Actually, I have a more magical and powerful recommendation algorithm here. Do you want to learn it?"

Xia Naitang was still covered in quilt, but her voice came out: "I don't want to inspire you!"

Chen Yu smiled: "I don't need you to help me inspire, I already know how to do it."

Xia Naitang then poked her cute head out of the quilt and looked at Chen Yu in the next bed with aggrieved eyes.

She bit her red lips: "Really?"

"of course it's true."

"Didn't lie to me?"

"I definitely didn't lie to you."

Xia Naitang nodded slightly, hummed, and asked, "What algorithm is it?"

Chen Yu smiled and patted the place next to him: "Come here and I will teach you."

Xia Naitang lowered his head and hesitated for a while, then finally hugged the quilt and returned to Chen Yu.

“Is there really a recommendation algorithm more powerful than this?”

"Of course! I have a recommendation algorithm model based on neural networks here."

While Chen Yu explained it to her seriously, he would steal glances at this cute little tiger from time to time.

"Teacher Xia, this model is composed of three layers of network. An input layer, an intermediate hidden layer, and an output layer. At the same time, it is also a standard autoencoder..."

Then, while he was talking, his hand crossed the little tiger's pink neck and gently rested on her tender and fragrant shoulders.

Chen Yu clearly felt that Xia Naitang's delicate body trembled slightly, but in the end she did not resist.

Just let Chen Yu hold her shoulders.

But in fact, Xia Naitang's fingers pulled on the hem of her nightgown and stirred it countless times.

At the same time, Xia Naitang did not dare to look at him at all, and kept staring at the computer screen.

Even at this moment, her mind was in chaos.

I couldn't listen to any of Chen Yu's explanation at all!

What on earth am I drawing?

Xia Naitang frowned her beautiful eyebrows and gritted her teeth, feeling a little regretful in her heart.

Knowing that this guy is a liar...

Why do you still want to take the bait? ! !

It was almost ten o'clock.

Once the biological clock is triggered...

Xia Naitang felt sleepy.

Gradually, she fell asleep in Chen Yu's arms.
