I'm in the county town, and you say I'm a big shot?

Chapter 18 "Payment and Goods!"

"You're working overtime, what a mess!"

"There's nothing we can do. The leaders of the city branch will come to inspect our work tomorrow, and everyone in the bank will have to work overtime." Fang Qingye replied lazily while sitting on a chair with his mobile phone in hand.

"What the hell! Your senior, the president, doesn't even give you any extra favors. Today is your highlight day." Song Dahai complained on the phone.

"Okay, it doesn't matter whether I go or not. You guys just eat well, drink well and have fun." Fang Qingye said with a smile.

"Don't worry, we won't save Jiang Chen!"

"Okay, bye." Fang Qingye hung up the phone with a smile on his face.

He didn't really want to go.

Even if I work overtime, it probably won't be too long. I can get off work at 5 o'clock and then get off work a little longer, and I can still get to the hotel later.

There are so many classmates here, I'm bound to get drunk tonight, so there's no need to show off.

Sure enough, the overtime work ended before seven o'clock. After eating the lunch box prepared by the leader, Fang Qingye rode his scooter directly home and started modeling.

The first step is data preprocessing. The Dongguan girl gave me a lot of investment data from a certain investment bank, and these data must be cleaned and transformed.

The so-called data cleaning refers to the processing of missing values ​​and outliers, and data transformation refers to the standardization, normalization and other dimensionless processing of data.

Fang Qingye made himself a cup of tea and sat at the computer to study.

Time flies when you have something to do. Soon it was past ten o'clock and Fang Qingye stretched.

Take a rest and do it again tomorrow.

Working late into the night?

Think more.

I've worked like a beast of burden in my previous life, and I don't want to be so tired in this life.

Let’s play a game first.

Fang Qingye had just opened World of Warcraft when his cell phone rang. He saw it was Song Dahai calling, so he picked it up and immediately heard Song Dahai's loud voice.

"Fuck! Ye Zi, you didn't come tonight, what a shame! Twelve tables of students, everyone's drinking like crazy!"

Fang Qingye was a little surprised. "12 tables? That's nearly a hundred students. How come so many of them are there?"

"Don't you know? Several classmates who work in the city and neighboring counties also rushed back. Also, some classmates who hadn't joined the group originally joined as soon as they heard about it. It was so lively. It's been several years since we graduated from high school, and the classmates have never been so gathered together for a reunion!"

"Jiang Chen must have spent a lot of money, right?" Fang Qingye said with a smile.

"That's right, he drank five boxes of Mengzhilan alone! Jiang Chen's face turned green in the end. We were supposed to go karaoke after drinking, but this guy used the excuse of being drunk to run away from the back door of the hotel! Haha. But the monk can escape, the temple cannot! He's going to the karaoke, and even Jesus can't stop him!"

shit
He was really drunk and even used his lines.

"Okay, okay, let's see how you do it."

The two chatted for a while before Fang Qingye hung up the phone.

Song Dahai was not the only one who called. They were all drunk and excited and had no place to vent. Some even asked Fang Qingye to teach them how to trade stocks, but he decisively refused.

"What are you teaching me? I took a gamble and won by luck, but I'm still losing money on my stocks."

"You ask me whether it will go up or down? It's hard to say, I really can't tell. I will get out as soon as I get out of this predicament."

By the time Fang Qingye finished chatting with these drunk classmates, it was already eleven o'clock.

Forget it, I won’t play games anymore. I’ll just take a shower and go to bed.

The next day Fang Qingye went to work on time, but what made him angry was that he received another notice from the department. It turned out that the leader of the municipal branch was coming to inspect the work, but the inspection was suddenly cancelled because the leader had an urgent matter and would come another day!
I wasted most of the day yesterday.

But that's how the workplace is. Leaders can arrange their own schedules at any time, but their subordinates can't.

The most annoying thing is that you work hard all day to prepare, but your boss comes to investigate and only takes a quick look for five minutes. How annoying!
Fang Qingye was no longer surprised. Since no one came to check, he could just go about his own business.

Dimensional processing, descriptive analysis, and then formal modeling begins.

According to the requirements, Fang Qingye established a prediction model. Common methods include time series prediction, regression analysis prediction, machine learning prediction, Markov prediction or other method combination prediction.

Forecasting using regression analysis
After another busy day, the digital model was built and the next step was model evaluation.

This step is also very important. Appropriate evaluation indicators can accurately measure the performance of the model. It seems that there is no time during the day, so let's do it at night.

That evening, Fang Qingye continued to work on his work. He decided to use metrics like the second-order mean square error (MSE) and the root mean square error (RMSE) for evaluation. Hmm.
The result is not bad.

Get it!

Fang Qingye logged into QQ.

There were several groups with unread messages, but he ignored them. The little penguin kept jumping, and the image of Chie Naka in a sailor uniform flashed.

She is from Dongguan.

Every time Fang Qingye logged into QQ, he could see her avatar flashing, but he usually ignored it unless, like today, there was something serious to discuss.

Fang Qingye clicked on the Dongguan girl’s profile picture, and a lot of messages immediately appeared.

"My husband, are you here?"

"My husband, I miss you. Although you are not by my side, we are still in this story. Even if I am not by your side, you are still my protagonist."

"Hey, you bastard, have you finished the digital model? If not, I'll do it myself!" Followed by a group of bloody knives.

Looking at these messy words, Fang Qingye sighed and replied, "It's done."

The other person’s profile picture immediately lit up, and the message arrived right away.

"Husband, you are finally here. I missed you so much."

So fast?
Fang Qingye suspected that this guy seemed to be holding a mobile phone or keyboard all the time?
"I miss your sister." Fang Qingye replied bluntly.

"But I don't have a sister. I have a cousin. Do you miss Ehuang and Nvying?"

"Shy" and "shy" expressions.

Fang Qingye felt that it was meaningless and said, "If you keep talking nonsense, I will log off."

"Okay, okay, you said you've finished writing it?" The Dongguan girl immediately became serious.

"Well, I'll send it to you. Pay the money and receive the goods." Fang Qingye reminded.

"Don't worry, you are my husband, how could I cheat you?"

Fang Qingye didn't say anything and handed the finished document over.

There was no response from the other party for a long time after receiving the message, but Fang Qingye was not anxious because he knew that the other party was conducting a digital model evaluation.

He poured out the tasteless tea, made another cup, and drank it slowly.

About twenty minutes later, the other person's profile picture started flashing again.

"Well written, my husband, you are great."

"Don't try to get close to me, just pay!"

"OK, send me your account number and I'll transfer the money to you right away."

Fang Qingye sent over his salary card account number and, of course, his real name.

"Husband, your name is Fang Qingye? What a literary name. Your father is a teacher, right?" The other party sent a line of words with a smile.

You guessed it right.

This name was given to him by his father, who was once a literary youth, but Fang Qingye didn't want to pay attention to it.

"Make money!"

This time, five minutes later, Fang Qingye received a text message on his mobile phone, indicating that 20 RMB had been transferred into his account.

Fang Qingye finally felt relieved.

He was really worried that the other party would fool him, pretend to be good after getting the model, and then log off and get away with it.

Fortunately, this Dongguan girl still has credibility.

Fang Qingye replied "Got it" on QQ and was about to log off when the other party suddenly asked, "Do you want to build another digital model?"

　Starting from today, I will post two chapters in a row, and tomorrow it will enter the first round of recommendations. I hope you can give me some votes to keep reading.
