Lan Xi’s purpose of coming to find Chen Xu was very simple. Just like last time, he asked him to create a cool CG special effects advertisement.

"The customer base of Audi A7 is mainly young people, full of personality, ostentatiousness, and self-centeredness, so the Volkswagen Planning Department has high requirements for the design of advertising cases, which must be in line with the aesthetics of young people, exercise, explosion, and people need to feel an intracranial orgasm at a glance, it must be it!"

After pausing, Lan Xi followed: "To be honest, I never imagined that such an advertising case is anything but the overall CG special effects production. Ordinary real-life promotional cases cannot meet the requirements at all."

Chen Xu picked up the spoon and stirred the coffee cup, saying, "Always Lan thought how good was the production level of the last cg special effect?"

Lan Xi said: "Well, the top international standards."

Although I felt a little embarrassed, Chen Xu still said: "Since that's the case, how about we negotiate at the top international standards?"

To be honest, Lan Xi gave him a big red envelope of 1 million in the bar last time, and he was quite moved.

But in Shangyan, the first time he "tested the clock", the second time he couldn't help her make special effects with no price because of being moved.

"Well..." As an advertising practitioner, Lan Xi naturally knew how expensive the production cost of CG special effects at the top international standards was, and she was a little confused for a while.

After pondering for a while, Lan Xi asked, "I don't know much about the specific foreign price. Can you tell me if you can listen."

Chen Xu said: "We calculate based on the charging standards of the four major special effects companies, including Industrial Light and Magic, Vita Digital, Digital Field and Sony Graphics and Image Operations. Their average production fee for each frame is $600, and 24 frames per second."

Lan Xi calculated in her mind that 600x24=14400 US dollars, calculated according to the current exchange rate, nearly 100,000 RMB per second...

"Hissing" to get this number, Lan Xi took a breath of cold air.

This advertisement is expected to take 150 seconds, which means that if Chen Xu asks to produce it, the production fee alone will be more than 15 million.

Chen Xu said: "Domestic special effects production costs often account for one-tenth of the total cost and one-twentieth of the total cost, but I don't need to say much about the effect of the shooting. Look at foreign countries. Generally, the special effects production costs are more than 40% of the total cost. For a movie with a total investment of US$100 million, the special effects cost will be more than 40 million US dollars."

Lan Xi was silent.

That being true, she also knows that the production cost of CG abroad is relatively high, but if the price is spent, wouldn't she look for those big companies to produce it? Why should she come to him?

Chen Xu paused and said, "For the sake of our second cooperation, I will give you 15% off for Mr. Lan, but the modeling needs to be handed over to your company to complete. Do you think it's okay?"

"Well..." Lan Xi hesitated.

When the company only had a few million capital, she dared to take a risk and dared to find Chen Xu, a "three-no-person" to produce CG special effects with a video; but now the situation has been opened, and Haoxin has more choices. To put it badly, she can find a big company to produce it.

Anyway, it’s not that I can’t afford the production fee, so why bother hanging him on his tree?

Of course, this is just thinking about it, Lan Xi did not intend to do this.

After all, Chen Xu and his behind-the-scenes production team have a more professional level in advertising production, and those top special effects companies may not necessarily produce better than what they do.

In other words, Lan Xi's short hesitation, the smile on Chen Xu's face gradually faded, "Okay, I understand! Then I'll leave first." As Chen Xu put down the spoon in his hand, stood up and walked out.

I had said before that this was a courageous woman, but I didn’t expect that I still looked down on her too highly.

At the same time, he felt a little embarrassed. He just jealous of the red and Lan Xi was about to make a lot of money again, and wanted to take the opportunity to get a little more.

Actually, it’s not that much, it’s just not much cheaper than those big companies.

But Lan Xi's expression reminded him that you are not worth the price!

This made his face feel a scorching pain.

"Wait for a moment Chen Xu... Teacher Chen should not leave..." Lan Xi did not expect that Chen Xu had a rift in his short hesitation and hurriedly chased after him.

"Teacher Chen, listen to me...

Our price is easy to negotiate...

Teacher Chen…”

"No need, Mr. Lan invites Gao Ming to another one." Chen Xu left the cafe and hurriedly.

Lan Xi, who was standing at the door, was depressed for a moment. She didn't know that she had just hesitated for a moment. Chen Xu was like a cat with her tail stepped on.

She hurriedly took out her cell phone and called Chen Xu, but she didn't answer.

Lan Xi sent him another message, "I'm sorry, Teacher Chen, I was just calculating the cost just now and didn't say I didn't agree. Please don't mind. Do you think this is OK? Everything is as you said. We will sign the contract tomorrow."

After the voice was released, Lan Xi stood at the entrance of the cafe and waited for five minutes, but there was no reply to the message there.

...

...

A week passed in a blink of an eye.

It rained on the morning of the 12th, with a storm and a storm. The Mid-Sea was shrouded in hazy mist and rain. Looking down from a high place, clouds and mists were surrounded by clouds.

Fortunately, I don’t have to go to school today on Saturday.

Chen Xu slept until nine o'clock before getting up.

Milk + bread + eggs, a perfect standard of living.

After finishing my meal, I started to study the information of the AI ​​challenge.

This was only when Ji Qinglin called him last night when he remembered it, otherwise he would have almost forgotten it.

The topics they grouped are text classification and clustering.

"Classification" is called lassifiation in English, and it is the most commonly used large-class algorithms in machine learning. Classification algorithms are usually called "classifiers".

This statement is actually very vivid, it is a black box with an entrance and an exit. A "sample" is thrown in at the entrance, and a classified "label" is expected to be obtained at the exit.

For example, a classifier can classify the picture content. We throw a photo of Taogu Erika at the "entry" and get a description label like "actor" at the "exit".

This is the most basic classification work process of a classifier.

"Clustering" is called clustering in English. This is a bit troublesome to explain in professional terms. We can call it "birds of birds of a feather flock together".

For example, when we were young, our parents taught babbling by reading pictures and speaking. There was a monkey on the picture, so we knew that this was a monkey;

There is a car in the picture, so we understand that it is a car, etc.

When we go out to the street or go to the zoo, the monkeys are not the monkeys on the paintings, and all kinds of monkeys look different. Will we recognize them as new things one by one?

No. We will just call them collectively monkeys.

When we look at cars, they are all kinds of size, color, style, and all kinds of things. Are they new things in our eyes?

No. They are all called cars.

This is called clustering, also called feathers of feathers gather.

Nowadays, the application of related technologies in big data analysis is relatively mature.

I just stayed on the sofa to read the information, and two hours passed without realizing it.

At noon, I was too lazy to cook and ordered takeaway.

After taking a break for half an hour, I planned to continue studying the data, but suddenly I felt very stupid again.

This kind of topic is of novices at all meaningless and cannot bring any benefits to their growth. If necessary, novices can generate dozens of internationally advanced classification and clustering models at any time.

As for him, there is no need to learn this kind of thing.

Even if you learn, you can only master one shortcoming in the short term.

What he needs to learn now is the directional knowledge of artificial intelligence.

Thinking of this, Chen Xu threw away the information.

Going to his grandma's is a waste of time and energy.

I looked at the time and it was less than a minute.

I got up and walked to the balcony and looked into the distance. The rain had stopped outside, but the north wind was still whistling.

"Xiaobai, how about we go to the gym to exercise together?"

The white audio breathing light on the TV cabinet behind me was on, "Okay. Do you need me to find a gym for you?"

"Um!"

"Within a kilometer, we will find 23 gyms in total, including 3 gym environments, equipment and other comprehensive scores above five stars. The nearest one is on the 36th floor of Jincheng Building, 500 meters away, called Dingshang Sports."

Chen Xu quickly put on his clothes and asked, "Is there a coach inside?"

Xiaobai said: "Some. I know two female coaches in it. They are both my good friends. I need me to make an appointment for you."

Chen Xu suddenly remembered Xiaobai's words.

It has added hundreds of WeChat groups, including fitness groups and fitness coach groups.

As for how it got involved in the fitness coach group, he didn't know this.

In short, there are novices’ friends in the entire Zhonghai City, and many people call it a confidant, so they ask it to go out for a party together if they have nothing to do.
Chapter completed!
