It is true that he promised to fund and participate in the competition with Meng Fanqi, because the reasons given by Meng Fanqi were very sufficient.

"If you get results in the competition, it will be of great benefit to you when you study abroad next year. To say the least, even if you get nothing, after the competition is over, no matter what the result is, this will be your own customized desktop computer."

Don Juan thought it made sense, and he didn't have the guts to directly ask for a computer at home, but he did have the guts to ask for the money in the name of a competition, and he was very brave.

Although I was brave, I didn’t expect that each component would be so expensive.

Fortunately, it doesn’t matter what kind of keyboard, mouse, monitor, or chassis you have. You can buy a low-end configuration. The heat dissipation should be about the same.

However, when all these factors are added up, the price of this computer is still as high as more than 26,000.

"It would be great to just buy a top-of-the-line brand machine." Various components are piled on the floor, making this small room seem extremely crowded and there is nowhere to stand. When a layman looks at it, he just feels dizzy and doesn't know where to start.

,Don Juan is very afraid of trouble.

"We don't have enough money for bulk packaging, so you still want to buy a brand-name machine? The price of a brand-name machine must be at least 30%, so you don't know how to install it, right?" Meng Fanqi knew that he was complaining like this, but in fact it was still very serious.

Focus on cost performance.

"30% for brand-name machines, double the number for brand-name machines, right?" Tang Juan laughed loudly. As a football and basketball fan, his roommate Brother Xu rarely plays in person and is not good at confrontation. Therefore, he loves NBA2k series, live football series and other games.

.Especially enjoys beating the top basketball player in the class, Brother Tao, who can easily shoot the basket.

Brother Xu just spent a lot of money to buy an Alienware laptop this year, but I don’t know if there is a problem with the heat dissipation or some other reason. It always freezes at critical moments, which is very annoying.

"It's not difficult to install this thing. I'll install it once and show it to you, and you'll learn how to do it later." Meng Fanqi said as he took out the motherboard, pressed down the metal hook on the top of the motherboard, and opened the protective cover. "This motherboard

It seems complicated, but in fact most of the things have nothing to do with us. The installation of accessories is fool-proof and easy to operate."

The things that need to be installed first on the motherboard are actually the CPU and two memory sticks. If it is air-cooled, you can install it first. For the CPU, just open the cover and put it in and snap it back. The memory sticks are even more fool-proof to operate.

, just plug it into a few slots. It’s no different from the game cartridges I used to play when I was a kid.

It’s just that the shapes of the DDR card slots of different versions of memory modules are different, and the motherboard and memory module models need to be aligned. Small details like this will make DIY assemblers’ blood pressure very high, and they will buy the wrong one if they are not careful. It is precisely because of this

, until 23 years, people still think that novices should just buy a brand machine.

After installing the air cooling, the motherboard can be fixed in the chassis. In fact, the most troublesome part of installing a computer by yourself is the wires. The power cords coming out from the power supply and the motherboard come in various shapes and shapes. The power supply is for the motherboard, and the power supply is for the motherboard.

The one for the graphics card, the motherboard for the hard drive, and even the button on the front of the chassis to connect to the motherboard.

"You should be careful about the cable situation. Don't just route the cables to save trouble. It's okay if it's ugly. Be careful not to block the slot for the graphics card on the motherboard." Don't ask him how he knew this.

AI algorithm engineers who are not proficient in installation are unqualified. Meng Fanqi has done this kind of thing from scratch at least five or six times, and he has done countless things like dismantling half of it and replacing components, so he is naturally familiar with the job.

Under his leadership, the two of them learned from each other, and when they worked together, they didn't lag behind him.

"Isn't the Windows system installed?" Tang Juan also thought that he could play games while it was running. Unexpectedly, Meng Fanqi did not install the Windows system directly, but installed Ubuntu 12.04 LTS.

"Linux series systems are much more stable. For Windows, if there is a conflict between some environments and there are any problems, it will be a big trouble."

Ubuntu's 2004 LTS series is very classic and easy to use. Some companies are even still using Ubuntu 16.04 LTS as their environment until 2022. It is a very safe choice.

"Okay, I've basically backed up the data and code. You can learn from the beginning when you have free time. If you don't understand anything, come to me anytime." After Meng Fanqi configured various environments and packages for a long time, time passed.

It’s already past six o’clock in the evening.

Since they had collaborated on papers and small competitions in their previous lives, Meng Fanqi also had the influence of Don Juan when he turned to this direction. However, Meng Fanqi really didn't know how to persuade others to drop out of school and turn this content as soon as he came back.

Now that Don Juan has finally embarked on this path, he naturally has to help his brothers.

Moreover, judging from his past life experience, although Don Juan has no talent in academics and innovation, his intuition is good in engineering practice and parameter tuning.

Nowadays, many drafts of my thesis have gradually taken shape, and I have accumulated a lot of experiments to run, and the parameters of many experiments have been adjusted and optimized. This kind of hard work can indeed be made much easier with someone to help.

Ever since he learned what Meng Fanqi was doing now, Tang Juan had gained a lot of corresponding knowledge.

If there is something that I still don’t understand, it is the conversion process of input and output by the AI ​​model.

According to Dean Fu’s mathematical understanding, the essence of a deep model is to use a very complex high-dimensional function to approximate a specific task or rule.

The process of model training is the process of gradually solving the function based on the function output value of each variable.

"So certain human task requirements or laws are actually very complex functions, which are far more difficult than some simple physical theorems. Just cats and dogs, it is already difficult for humans to summarize some clearly stated and correct rules.

Rules.

Even if I can explain it clearly, if I continue to expand the question to cats and canines, or continue to expand the question to the thousand categories we have classified this time, people can still explain it clearly and summarize accurate information based on more than 10 million pictures.

Is it regular?"

Don Juan thought about it, let alone asking him to summarize the rules of how to accurately distinguish a thousand categories. He probably couldn't memorize all of the thousand categories. It was hard to imagine that the Alex Meng Fanqi asked him to see could already classify in a thousand categories.

achieve such a high accuracy rate.

"You know, whether they are cats or dogs, they basically cannot pass the 'mirror test'. That is to say, they cannot detect that the creature in the mirror is themselves." Don Juan suddenly felt a little emotional,
