The third year of the Department of Computer Science at the University of Tokyo.

Because of yesterday's "talk show", Chen Xu, who was originally unknown, suddenly became famous in the department, and someone greeted him on the road.

And Ji Qinglin and Liu Zhuoran now seem to be his good brothers.

People are vain, and Chen Xu is no exception, although he is not complacent, but those adoring eyes and flattering words really make him feel very wonderful.

Then he kept telling himself in his heart that what you have to overcome is your vanity, your desire to show off, and your cleverness that always wants to be in the limelight.

Down-to-earth, one step at a time!

After the first class in the afternoon, the admissions office of the AI interest group called him and Ji Qinglin to inform them and asked them to come over, and it seemed that the review had passed.

And Liu Zhuoran, who dragged them there, seemed to have been eliminated, which made Liu Zhuoran depressed.

Chen Xu and the two came to the comprehensive building, the assessment has ended, a total of 72 people signed up, but only 10 people were enrolled. 8 males and 2 females, 4 first-year students, 1 senior student, 3 juniors, and two freshmen.

The professor who chaired the meeting yesterday waited for him to sit down and said, "You must already know the relevant information about this AI Global Challenge, and the whole competition is divided into three stages.

First of all, the Zhonghai University Competition, then the National University Competition, and finally the AI Global Challenge will be held at Google's global headquarters. The duration is three months......"

The professor went through some of the rules, and then talked about the choice of specific topics.

Ji Qinglin whispered: "Chen Xu, what kind of 'fine-grained user sentiment analysis' the professor said, do you understand?"

This is a field of study at the master's level in computer science, and they have not yet learned it.

Chen Xu said: "This is a classification under the field of natural language processing, allowing machines to mine valuable things such as user emotion, which is currently mainly used in personalized recommendations and intelligent search." ”

Ji Qinglin suddenly realized: "Oh, I know, this is the algorithm recommendation of Shake Yin, right?"

Chen Xu nodded, "Not bad." If you stay on a video for an extra second, such as a young lady, a pet, a celebrity, a show off of wealth, a car, etc., a fine-grained user sentiment analysis can calculate what type of video you like in your heart, and then keep recommending it to you, so that you can see it until you vomit. ”

Ji Qinglin said: "It feels really terrifying. ”

"Horror? Tell you, let alone search engines now, some aggregators will monitor your microphone, and if you call and mention a certain product, the next day the relevant product recommendation will appear on your app page. ”

Ji Qinglin: "......"

Just as the two of them were chatting, the professor on the stage said: "Let's start grouping, the first group is Zhang Hao, Wang Wenbin, Lin Junfeng, Xue Hang, Cheng Siyu, and the second group is Chen Xu, Ji Qinglin, Yang Shihan, Zhou Kuo, and Fu Anxin. ”

Ji Qinglin looked at Fu Anxin for the first time, a girl with a mediocre appearance and a mediocre figure, and there were many freckles on her face, and she was immediately disappointed.

went to look at the other group of girls named Cheng Siyu, whose breasts were obviously much larger than Fu Anxin's.

"The relevant materials of the project will be collected by Zhang Hao. I would like to emphasize here that you must not think that it is really an interest group, you must take it seriously and go all out, as long as you get a good ranking, in addition to the rewards of the challenge itself, there will also be additional rewards in the department. Did you hear me clearly?"

"Got it. ”

"Okay, let's break up. ”

The professor handed over a thick stack of materials to Zhang Hao, the "great god" of the computer department, and asked him to distribute it.

Zhang Hao is two terms taller than Chen Xu, he is in graduate school this year, he is one meter eight and zero, looks Sven, wears a set of black Adidas, white sneakers, and is simply the prince charming in the minds of girls.

After the rest of the people received the information, Zhang Hao walked up to Chen Xu and pestle the information in front of him, "Oh~"

"Thank you~" Chen Xu took the information.

Zhang Hao said with a bit of arrogance: "Chen Xu, right, I watched yesterday's video, you are very strong." ”

Chen Xu said: "I passed the award, but I just read a little more books." ”

Zhang Hao asked, "Which topic do you plan to choose?"

Chen Xu said: "Machine translation. ”

"Oh?" Zhang Hao was surprised, and then said, "It's not easy to come up with results." Moreover, Fudan University has a strong disciplinary advantage in machine translation, are you sure you want to choose machine translation?"

Chen Xu smiled and said: "The academic advantage only represents the achievements we have made, and we are facing a group of peers who are similar to us, and we are afraid that he will do anything. Crush them!"

"You're awesome. Zhang Hao gave a thumbs up, but he didn't feel a hint of praise in his words, as if he was saying that he didn't measure himself.

The two chatted for a while, and Zhang Hao said: "I heard that there is a strong foreign aid, maybe he can really qualify for the group!"

Chen Xu said strangely: "Who?"

Zhang Hao: "Jiang Xiaorou." We are the daughter-in-law of Dean Jiang, and now she is studying for a Ph.D. in computer science at Princeton University, focusing on natural language processing. ”

After a pause, Zhang Hao followed: "By the way, she is only 21 years old this year." Same age as us. ”

Chen Xu: "So powerful?"

"There are many powerful people in this world!" Zhang Hao turned around and said, "Let's go." ”

Chen Xu nodded, and then walked towards Ji Qinglin and them.

……

……

At six o'clock in the evening, Chen Xu was having dinner with Ji Qinglin and Liu Zhuoran in the cafeteria, Chen Yi sent a video over, and Chen Xu turned on the Bluetooth headset to chat with her while eating.

On the phone, Chen Yiyi reproached in a happy tone: "Brother, why do you buy me a luxury like four-leaf clover." ”

"My sister deserves the best thing in the world. ”

"Wow~ Brother, when did you become so good at talking. ”

"Hehe, I've been in contact with all kinds of girls lately, and my eloquence has been tempered to a certain extent. ”

"That's right~ There is money to meet thousands of miles away, and there is no money on the other side, and I don't know each other, horizontal criticism, it's good to be rich!"

"Why do I sound so sour? Anyway, where is the wife you introduced to your brother?"

"Wait a minute, Weixin, you can talk alone. Her father is an official, at the department level. ”

Chen Xu: "...... Forget it, Miss Guan can't afford to lick it, so change it. ”

Chen Yiyi couldn't stop laughing when he heard this, and said before hanging up the phone: "Sister seems to be in love, when I was talking to her on the phone two days ago, I heard a male voice calling her nickname." ”

Waiting for Chen Xu to hang up the phone, Liu Zhuoran was curious: "Chen Xu, you still have a sister." ”

Chen Xu belongs to the introverted personality, which is commonly known as sullenness, a few years in college, the relationship with his classmates is average, there are no classmates who are particularly close, except for a few people in the dormitory, most people don't know his family situation.

Seeing Liu Zhuoran asking, Chen Xu nodded, "Hmm!"

"What are you going to do now?"

"Read. ”

"Where?"

"Yan Da. ”

"Damn, awesome. ”

Originally, the two people who were about to flow out and were ready to call him uncle at any time, as soon as they heard that Chen Xu's sister was studying at Yan University, they knew that she was a scholar, and they were such scumbags.

Ji Qinglin asked, "In addition to one sister, do you have other brothers and sisters in your family?" ”

Chen Xu: "Uh...... There is also an older sister. ”

Ji Qinglin: "What is she doing now." ”

Chen Xu: "I'm taking the exam." ”

“…… Awesome~"

Ji Qinglin and Liu Zhuoran felt that they shouldn't ask.

Just when a few people were chatting, Chen Xu's phone rang again, and when he took it out, he saw that it was Lan Xi calling.

After connecting, Lan Xi said that there was something to discuss with him.

The two of them made an appointment on the phone, and after hanging up the phone, Chen Xusan finished eating in two bites, said goodbye to Ji Qinglin and Liu Zhuoran, and left in a hurry.

Ji Qinglin and the two also heard Chen Xu's conversation, and they were surprised again, feeling that this classmate, who was ordinary and completely half transparent, was now full of a sense of mystery.

……

Although the cold wind on the winter night is bleak, the Linjiang Avenue still can't stop the hustle and bustle of the crowd, and the shops along the river emit bright lights, making this financial capital shine.

After Chen Xu left school, he drove to an Italian café on the edge of the river.

In the warm Italian café, Lan Xi and Chen Xu chatted while drinking coffee.

"No. 1 our advertising case has been officially logged on the all-media platform, which has been well received, and some media influencers have also written articles on advertising production for an in-depth and comprehensive analysis, and we are considering participating in this year's Great Wall Award selection. ”

The "Great Wall Award" is the most important advertising selection in China's advertising industry, which is equivalent to the "Hundred Flowers Award" in the domestic film industry.

After a pause, Lan Xi said excitedly: "In addition, Volkswagen's Audi A7 sent us an advertising invitation yesterday, and according to last year's standards, the total cost of the project is about 60 million to 80 million yuan." ”

Chen Xu was surprised when he heard this.

There are three main costs of an advertising company: publicity, production, and design.

Among them, propaganda accounts for the main majority, about fifty percent, according to the total scale of the compromise of 70 million, the publicity cost should account for 35 million, and then the design and production, according to domestic practice, this cost accounts for forty percent of the remaining funds, about 14 million.

The remaining 21 million is Haoxin's net profit.

Anyway, after this order is done, Lanxi can earn at least 15 million ~ 18 million.

A profit margin of 25% is already low in the advertising world.

At this moment, Chen Xu's eyes were red......
