It is true that he promised to invest money to 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. 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 and chassis it is. You can buy it with lower configurations. The heat dissipation is about the same.
However, when all is 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 were piled on the floor, making this small room look extremely crowded and there was 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 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 played in person and was not good at confrontation. Therefore, I love NBA2k series, live football series and other games. He was especially happy to beat the top basketball player in the class, Brother Tao, who could dunk easily.
Brother Xu just spent a lot of money to buy an Alienware laptop this year. I don’t know if it’s a heat dissipation problem or some other reason, but 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 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 modules. If it is air-cooled, you can also install it first. For the CPU, you only need to open the cover, put it in and snap it back in. The memory module is an incomparable fool-proof operation, 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 can make a DIY assembler’s blood pressure go up, and they can end up buying the wrong thing if they’re not careful. It is precisely because of this that until 2023, everyone still felt that novices should just buy a branded machine.
After installing the air cooling, the motherboard can be fixed in the chassis. In fact, the most annoying part of installing a computer by yourself is the wiring. The power cords that come out from the power supply and motherboard come in many shapes and sizes. The power supply is for the motherboard, the power supply is for the graphics card, the motherboard is for the hard drive, and even the buttons on the front of the chassis are connected 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 reserved 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. Naturally, he is familiar with the job.
Under his leadership, Don Juan followed his example, but did not 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 .04 LTS series is very classic and easy to use. Some companies even used Ubuntu 16.04 LTS as their environment until 2022. It's a very safe choice.
"Okay, I've basically backed up the data and code. You can learn it from scratch when you have free time. If you don't understand anything, come back 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 together in their previous lives, I was also influenced by Don Juan when I turned to this direction. But Meng Fanqi really didn't know how to persuade people to drop out of school and repost this content as soon as he came back.
Now that Don Juan has finally embarked on this path on his own, 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. I have also adjusted and optimized the parameters of many experiments. This kind of hard work can indeed be much easier if I have someone to help me.
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 can't figure out, 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 law.
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. law.
Even if it is clear, if I continue to expand the question to cats and canines. Or continue to expand the problem. When we classify it into a thousand categories this time, can people still explain it clearly and summarize accurate patterns based on more than 10 million pictures? "
Don Juan thought about it a lot, and even if he was asked to summarize the rules of how to accurately distinguish a thousand categories, he might not be able to memorize all of the thousand categories. It is hard to imagine that the AlexNet that Meng Fanqi asked him to see can already achieve such a high accuracy in thousands of categories.
"You know, whether they are cats or dogs, they basically cannot pass the 'mirror test'. In other words, they cannot detect that the creature in the mirror is themselves." Don Juan suddenly felt a little emotional,
"I feel now that humans cannot understand the patterns summarized by AI, just like animals that fail the mirror test. They always want to look behind the mirror, but they may not be looking in the right direction at all."
