Lan Xi's purpose in coming to Chen Xu is very simple, like last time, ask him to create a cool CG special effects advertisement.

"The customer base of the Audi A7 is mainly young people, they are full of personality, publicity, and self, so the Volkswagen Planning Department has relatively high requirements for the design of the advertising case, which must meet the aesthetics of young people, and it must be sporty, explosive, and make people feel an intracranial orgasm at a glance!"

After a pause, Lan Xi followed: "To be honest, such an advertising case, except for the overall CG special effects production, I can't think of anything else, and ordinary real-life publicity cases can't meet the requirements at all." ”

Chen Xu picked up the spoon and stirred the coffee cup, and said, "What does Mr. Lan think of the level of CG special effects production last time?"

Lan Xi said: "Well, the international top level. ”

Although he felt a little embarrassed, Chen Xu still said: "In that case, how about we talk about the price at the top international level?"

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

But in business, the first time she "tried the clock", the second time she couldn't help her make special effects at the price of cabbage because she was moved.

......As an advertising practitioner, Lanxi naturally knows how high the cost of CG special effects production is at the top international level, and he was a little hesitant for a while.

After a deep sigh, Lan Xi asked: "I don't know too much about the specific foreign prices, can you tell me about it." ”

Chen Xu said: "Let's calculate the fees of the four major special effects companies, Industrial Light & Magic, Weta Digital, Digital Domain, and Sony Graphics & Image Operations, and their average production fee for each frame is 600 US dollars, 24 frames per second. ”

Lan Xi calculated in his heart, 600×24 = 14,400 US dollars, according to the current exchange rate, nearly 100,000 yuan per second......

"Hiss-" Drawing on this number, Lan Xi gasped.

This advertisement is expected to be 150 seconds, that is to say, if Chen Xu is asked to make it, the production cost alone will be more than 15 million.

Chen Xu said: "The production cost of domestic special effects often accounts for one-tenth or one-twentieth of the total cost, but I don't need to say much about the effect. If you look at foreign countries, the general special effects production cost is more than 40% of the total cost, and a movie with a total investment of 100 million US dollars will cost more than 40 million US dollars in special effects. ”

Lan Xi was silent.

Although that's right, she also knows that CG production fees abroad are relatively high, but if she spends the same price, wouldn't she look for those big companies to produce, so why bother to come to him?

Chen Xu paused for a moment and said with a smile: "For the sake of our second cooperation, I will give you an eighty-fifty discount for Mr. Lan, but the modeling part needs to be handed over to your company to complete." Do you think it's okay?"

"Well...... this" Lan Xi hesitated.

When the company only has a few million capital, she dares to take a risk, and dares to find Chen Xu, a "three-no-personnel", to make CG special effects with a video, but now that the situation has opened, Haoxin has more options, to put it mildly, she can find a large company to produce.

Anyway, it's not that he can't afford the production fee, so why hang himself on this tree?

Of course, this is just a thought, Lanxi 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 are not necessarily better than them.

That is, after Lan Xi's short hesitation, the smile on Chen Xu's face gradually faded, "Okay, I understand! Then I'll go first." As he spoke, Chen Xu put down the spoon in his hand, stood up and walked out.

I said before that this is a woman with courage, but I didn't expect to think too highly of her.

At the same time, he felt a little embarrassed, he was just about to make a lot of money just now, and he wanted to take the opportunity to ask for more.

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

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

It made him feel a burning pain in his face.

"Wait a minute, Chen Xu...... Teacher Chen, don't go......" Lan Xi didn't expect that his short hesitation would make Chen Xu suspicious, and hurriedly chased after him.

"Teacher Chen, listen to me......

Let's negotiate the price......

Teacher Chen......"

"No need, Mr. Lan will ask for another master. Chen Xu left the café in a hurry.

Lan Xi, who was standing at the door, was depressed for a while, how could she know that she just hesitated, Chen Xu was like a cat with its tail stepped on.

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

Lan Xi sent him a letter again, "I'm sorry Mr. Chen, I was just calculating the cost just now, and I didn't say I disagreed, please don't mind." You see if this will work, everything will be done according to what you say, and we will sign the contract tomorrow. ”

After the voice was sent, Lan Xi stood at the door of the café and waited for a full five minutes, but there was no reply to the message.

……

……

A week passed in the blink of an eye.

It rained on the morning of the 12th, and the wind and rain were rapid, and Zhonghai was shrouded in hazy smoke and rain, and when it looked down from a high place, the clouds covered the fog.

But fortunately, today is Saturday, and there is no need to go to school.

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

Milk + bread + eggs, a proper well-off standard of living.

After eating, I started researching the materials of the AI Challenge.

This was only when Ji Qinglin called him last night to remind him, and he wanted to remember it, otherwise he would have forgotten about it.

The topic assigned to the group was text classification and clustering.

"Classification" is the most commonly used algorithm in machine learning, and the classification algorithm is usually called "classifier".

This statement is actually very vivid, it is a black box, there is an entrance, there is 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 be used to classify and label the content of the image, and we throw a photo of Erika Momoya in the "entrance", and get a description tag like "actress" in the "exit".

This is the most basic classification process of a classifier.

The English name of "clustering" is Clustering, which is a bit troublesome to explain in professional terms, we can call it "clustering of things by like".

For example, when we were children, we had a similar experience when our parents taught us to babble by looking at pictures and talking, and we knew that it was a monkey when the picture was drawn.

A car is drawn on the picture, so we understand, it's a car, and so on.

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

No. We'll just refer to them collectively as monkeys.

We look at cars the same, size, color, style, all kinds of things, are they new things in our eyes?

No. They are all called cars.

This is called clustering, also known as clustering of things by like.

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

I just nestled in the sofa and read the information, and before I knew it, two hours had passed.

At noon, a person was too lazy to cook and ordered takeout.

After eating and resting for half an hour, I was going to continue researching the data, but suddenly I felt stupid again.

This kind of subject is of no significance to Xiaobai, and it can not bring any benefits to its growth, if necessary, Xiaobai can generate dozens of internationally advanced classification and clustering models at any time.

As for him, there is no need to learn such a thing.

Even if you learn, you can only master one surface 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.

his grandma's, a waste of time, a waste of energy.

Looking at the time, it was less than one o'clock.

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

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

The white audio breathing light on the TV stand behind him lit, "Okay." Need me to find a gym for you?"

"Hmm!"

"Within a kilometer, a total of 23 gyms will help you, of which 3 gyms have a comprehensive rating of more than five stars for their environment and equipment, and the nearest one is on the 36th floor of Jincheng Building, 500 meters away, called Dingshang Sports. ”

Chen Xu quickly got dressed and asked, "Is there a coach inside?"

Xiaobai said: "Yes." I know two female coaches, they are my good friends, and I need to make an appointment for you. ”

Xiaobai's words, Chen Xu suddenly remembered.

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

As for how it got into the fitness trainer group, he doesn't know this.

In short, now there are Xiaobai's friends in the entire Zhonghai City, and many people have introduced him as a confidant, so they ask him out to party if he has nothing to do.

Let Xiaobai help him make an appointment with one of the fitness trainers, and then hurried downstairs to the gym.
