Rebirth: I Carry A Desktop Computer Inside Me - #87 - Chapter 87: Use Your Big Moves As Soon As You Arrive, Okay?

Office of Professor of Computer Science, Shuimu University.

Yang Mingde was also a little surprised. He looked at Jiang Cheng and wondered what Jiang Cheng was talking about.

Is it possible that you are secretly tinkering with some good algorithm again?

“I made a battery fast-charging chip, which should be used in your company’s consumer business.” Jiang Cheng looked at Yu Shengdong and then explained.

It’s probably because I was dozing off that I just happened to get a pillow.

Yu Shengdong was a little surprised, “Quick charge, how fast is it?”

“Theoretically, 40W can be achieved, but it requires material and technical support. However, 22.5W can be achieved as long as the existing power adapter is improved.”

Yu Shengdong thought and nodded slightly, “Battery fast charging is not a matter of a chip. Not to mention where your product is, whether the theory has been verified, and whether the cost can be controlled within an acceptable range. Just mentioning fast charging is also necessary. The power adapter, charging cable, and mobile phone battery terminal are all improved together.”

Jiang Cheng said calmly, “However, currently, there is no fast charging technology on the market. The significance of the launch is to lead.”

“You are right, this is indeed the meaning of research and development.” Yu Shengdong smiled, “You should have established a company by developing this chip, right?”

“It’s been built, but it’s still in the start-up stage.”

“Has the chip been taped out?”

“It’s being taped out.”

“…” Yu Shengdong laughed, “Professor Yang, you are really an amazing student, you are very motivated.”

Yang Mingde shook his head and smiled bitterly, “Jiang Cheng, don’t be anxious, take your time.”

Jiang Cheng paused and said, “I was the one who was abrupt.”

“Hey, that’s not what I meant.” Yu Shengdong stretched out his hand and said, “You are Professor Yang’s favorite student. I am willing to believe you. I will arrange for two technicians to come over to understand the possibility of technology implementation. If it is indeed good, I think It’s not too late for us to discuss further cooperation.”

Jiang Cheng agreed. He was talking nonsense and it was good to get such an attitude from the other party.

Of course, Jiang Cheng also believes that if he is given more time, the chip and control system will become finished products.

By then, he himself will also have the ability to select people to cooperate with him.

But he has always had a favorable impression of Warwick Company.

Before Yu Shengdong left, he gave Jiang Cheng a business card, “Shuimu is a place where talents come out in large numbers. Although you are only a student now, I still believe that the future technology will be your stage.”

After they left, Yang Mingde asked, “Good boy, when did you start designing chips?”

“I spent some time studying circuit design on my own,” Jiang Cheng said modestly.

Yang Mingde was a little confused and shook his head, “Then which direction do you plan to study? You already have a high level of deep learning, and I plan to take you to see Professor Xia Luo later.”

“Hey, teacher, can I tell the truth?” Jiang Cheng asked with a smile.

“Say it.”

“I want to learn them all.” Jiang Cheng said honestly, “In our department, I want to learn artificial intelligence and big data algorithms, and I also want to go to the microelectronics department to learn chip design.”

Yang Mingde was a little dizzy, “Xiao Jiang, people’s energy is limited. Now is the era of social division of labor. It is impossible for one person to be proficient in everything.”

“Oh.” Jiang Cheng blinked.

I might be an exception.

“You have a company now?” Yang Mingde asked again.

“Yes, several have been opened. A game company, Maple Fire Games; and a film and television special effects company.” Jiang Cheng naturally had nothing to hide when facing Yang Mingde.

Yang Mingde is not interested in games, “Special effects company? Why are you doing special effects again?”

“Didn’t I also learn software engineering and make a special effects production software.” Jiang Cheng felt that it was normal.

“…” Yang Mingde saw that this little guy really couldn’t be looked at with ordinary eyes.

However, it doesn’t feel like the second generation of rich people.

Are you really starting from scratch?

Yang Mingde could only attribute Jiang Cheng to a genius.

“The facial recognition patent belongs to the school. As the project leader, although there are some rewards, I guess you won’t like it.” Yang Mingde reminded.

“I understand, thank you teacher.” Jiang Cheng was sincerely grateful.

Professors in some schools take the research results of their students as their own and do not even name them.

But Yang Mingde doesn’t know how to do it. He is highly respected and respected.

“Let’s go, I’ll take you to Professor Luo.” Yang Mingde stood up and said as he walked, “You have no problem with your grades. I remember you are all excellent.”

“Yes.”

“There are two papers in total, right?”

“There are three articles. Two of them were under your guidance, so I added a name. I wrote a paper on deep learning algorithms for special effects software and published it.” Jiang Cheng explained.

Yang Mingde nodded, “That’s no problem.”

After a while, the two arrived at Professor Luo Ruihua’s office.

Professor Luo Ruihua is much younger than Yang Mingde, quite tall, and very energetic.

“Lao Yang, you are here.”

“Lao Luo, I’ve got a treasure for you.”

The two professors greeted each other, and Luo Ruihua looked at Jiang Cheng behind him.

Jiang Cheng had attended his classes several times and knew him, but Luo Ruihua did not know him.

He often attends meetings everywhere, and his research is not fixed in Shuimu. It is not easy to find him.

“Professor Luo, I am Jiang Cheng from level 11.”

With the boss in front, Jiang Cheng was extremely humble.

Luo Zhenhua nodded, “I heard Lao Yang say it several times, saying that you have done a lot of research in the field of deep learning, and you also showed me your questions. It’s really good. You have spirituality and understanding.”

After sitting down while talking, Yang Mingde added, “Oh, if this guy didn’t like my research direction, I wouldn’t be willing to give it to you.”

Jiang Cheng acted like a good boy and didn’t speak unless I asked.

“Xiao Jiang, no matter how much you listen to Lao Yang, I will still test you.” Luo Zhenhua stretched out his hand and handed over the blank piece of paper in his hand. “Just one question, half an hour, whatever step you can do will be counted as one step.”

“OK.”

Jiang Cheng took it with both hands, followed Luo Zhenhua’s instructions, and sat down on his desk.

The two big guys were drinking tea and chatting on the sofa.

Jiang Cheng took a look and said, good guy, what should I answer?

[Each layer in CNN (Convolutional Neural Network) is composed of multiple maps. Each map is composed of multiple neural units. All neural units in the same map share a convolution kernel (ie, weight)… Due to the As the number of model layers increases, problems such as gradient explosion, gradient disappearance, and gradient dispersion will often occur, leading to network degradation. How do you think it should be optimized? 】

Jiang Cheng was a little speechless. He used his big moves as soon as he came. Is that okay?

Fortunately, after nearly a year of research on deep learning and neural networks, Jiang Cheng was not confused. He subconsciously moved the pen around his fingertips, and took out the idle virtual machine of the computer in his body and started working directly.

I summarized some of my previous ideas while experimenting.

Ten minutes later, Jiang Cheng began to answer.

“Set the residual block under 2 to several layers, defined as F(x)+x… In this way, the residual can be expanded by Kronecker product with a scale*scale all-1 matrix, so that the residual of the sampling layer The dimension of the difference is consistent with the dimension of the output map of the previous layer…”

Under the text, Jiang Cheng wrote a formula.

Comfortable regular script and beautiful characters flow from the tip of the pen.

Half an hour ended quickly, but Jiang Chengfang had only written about 2/3.

For this solution, Jiang Cheng initially had a small idea in his body’s computer and tried it.

The countdown of the alarm clock in his body rang, and Jiang Cheng stopped.

“Professor Luo, your questions are too difficult. I answered some of them. Due to time constraints, some of them were left unfinished…” Jiang Cheng handed over two pages of fully written white paper.

Luo Ruihua nodded and took a look.

I quickly became immersed in it.

Hey, where’s the back?

After a few minutes, he saw the end.

“What’s next, do you have any ideas?” Luo Ruihua was a little anxious.

“Isn’t it time?”

“Oh, why bother with time? We have plenty of time. Hurry up and write down your next thoughts.” While speaking, he personally took a few pieces of white paper and handed it over.

Yang Mingde glanced at it a few times, feeling somewhat relieved.

It seems that this seedling is better than I imagined!
