Rebirth: I carry a desktop computer inside me

Office of the Professor, Department of Computer Science, Mizuki University.

Yang Mingde was also a little surprised, looking at Jiang Cheng, not knowing what Jiang Cheng said.

Could it be that you secretly tinkered with some good algorithm?

"I have a battery fast charging chip, your company's consumer business, should be able to use." Jiang Cheng looked at Yu Shengdong and then explained.

It can be considered that drowsiness happened to bring pillows.

Yu Shengdong was a little surprised, "Fast charge, how fast to charge?" "

Theoretically it can do 40W, but it requires material 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 chip thing, not to mention where your product is, whether the theory has been verified, whether the cost can be controlled within an acceptable range, just to improve fast charging, it is also necessary to improve the power adapter, charging cable, and mobile phone battery end."

Jiang Cheng said calmly, "However, at present, there is no fast charging technology on the market, and the meaning of the first launch is to lead."

"You're right, that's really what research and development is all about." Yu Shengdong smiled, "You should have established a company when you engage in this chip, right?" "

It was built, but it's still in the start-up phase."

"Have the chips taped out?"

"Tape-out."

Yu Shengdong smiled, "Professor Yang, you are really a great student, very impulsive."

Yang Mingde shook his head and smiled bitterly, "Jiang Cheng, you are not in a hurry, take your time."

Jiang Cheng paused and said, "It's that I'm abrupt."

"Well, I didn't mean that." Yu Shengdong stretched out his hand and waved down, "You are Professor Yang's proud student, I want to believe you, I will arrange two technicians to come over and understand the possibility of technical realization." If it is really good, I think it will not be too late for us to talk about further cooperation.

Jiang Cheng agreed, he was talking in vain, and it was already 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 a finished product.

At that time, he himself will also have the ability to pick people to cooperate.

But he has always had a good impression of Warwick.

Before Yu Shengdong left, he gave Jiang Cheng a business card, "Mizuki is a place of talents, although you are only a student now, I still believe that the future technology will be your stage."

After the people left, Yang Mingde asked, "Good boy, when did you still design chips?"

"I spent some time teaching myself on circuit design." Jiang Cheng said modestly.

Yang Mingde was a little puzzled, 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 meet Professor Luo later.

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

"Say it."

"I want to learn." Jiang Cheng said honestly, "We want to learn artificial intelligence and big data algorithms, and we want to go to the microelectronics department to learn chip design."

Yang Mingde was a little dizzy, "Xiaojiang, people's energy is limited. Now is the era of socialized division of labor, and it is impossible for one person to be proficient in everything. "

Oh." Jiang Cheng blinked.

I may be an exception.

"You start a company now?" Yang Mingde asked again.

"Yes, a few of them. a game company, Maple Fire Games; There is also a film and television special effects company. Jiang Cheng faced Yang Mingde, naturally there was nothing to hide.

Yang Mingde was not interested in the game, "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 normal.

Yang Mingde could see that this little guy really couldn't look at it with ordinary eyes.

However, the rich second generation, it doesn't feel like it.

Really started from scratch?

Yang Mingde could only reduce Jiang Cheng to the category of geniuses.

"The face recognition patent is owned by the school, as the project leader, although there are some rewards, it is estimated that you will not look at it." Yang Mingde reminded.

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

Professors in some schools take the students' research results as if they were already available, and they don't even add a single name.

But Yang Mingde will not, morality is highly respected, exactly that.

"Let's go, I'll take you to Professor Xia Luo." Yang Mingde got up, and then said as he walked, "You have no problem with these grade points, I remember that you are all excellent."

"Yes."

"That's two papers, right?"

"Three articles, 2 under your guidance, I will add a name; I wrote a paper on deep learning algorithms in 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, he is quite tall, and he is also very spiritual.

"Lao Yang, you're here."

"Lao Luo, I sent you a treasure."

The two professors said hello, and Luo Ruihua looked at Jiang Cheng behind him.

Jiang Cheng had audited 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 Mizuki, so it is not easy to find him.

"Professor Luo, I'm Jiang Cheng from level 11."

The big guy was in front, and Jiang Cheng was extremely modest.

Luo Zhenhua nodded, "I heard Lao Yang say several times, saying that you have studied deeply in the field of deep learning, and you have shown me your problem, which is indeed good, spiritual, and understanding."

After sitting down while speaking, Yang Mingde said again, "Alas, if it weren't for the fact that this kid didn't like me to study the direction, I wouldn't be willing to give it to you." "

Jiang Cheng is honestly a good baby, and he doesn't talk if he doesn't ask me.

"Xiaojiang, no matter how much Lao Yang says, I will also test you." Luo Zhenhua reached out and handed over the first blank piece of paper in his hand. "Just one topic, half an hour, which step you can achieve, count one step."

"Okay."

Jiang Cheng took it with both hands, and sat down on his desk as Luo Zhenhua said.

The two big guys drank tea at the sofa and chatted.

Jiang Cheng looked, good guy, what should I answer?

[Each layer of CNN (convolutional neural network) is composed of multiple maps, each map is composed of multiple neural units, and all neural units of the same map share a convolution kernel (that is, weights)... As the number of layers of the model used increases, problems such as gradient explosion, gradient vanishing, and gradient diffusion are often encountered, resulting in network degradation. How do you think it can be optimized? ]

Jiang Cheng was a little speechless, and he would amplify the move as soon as he came, is this good?

Fortunately, after nearly a year of deep learning and neural network research, Jiang Cheng will not be confused, the pen at hand subconsciously circles around his fingertips, and the virtual machine that is idle in the computer in the body is taken out and directly dried.

Put some of my previous ideas, while experimenting, while summarizing.

Ten minutes later, Jiang Cheng began to answer.

"Set up residual blocks under 2 to several layers, defined as F(x)+x... In this way, the residuals can be extended with the Cronecke product of a scale*scale all-1 matrix, so that the dimension of the residual of the sampling layer is consistent with the dimension of the output map of the previous layer..."

Below the text, Jiang Cheng wrote the formula.

Comfortable lines and beautiful characters flow down the nib.

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

This solution, Jiang Cheng initially had some small ideas in the internal computer and tried it.

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

"Professor Luo, your topic is too difficult, I answered some, time is the matter, and some have not been completed..." Jiang Cheng handed over two blank pages full of writing.

Luo Ruihua nodded and took a look.

Soon immersed.

Eh, what about the back?

A few minutes later, he saw the end.

"What about the back, do you have an idea?" Luo Ruihua was a little anxious.

"It's not time."

"Oh, what about the time, the time is, quickly, write down the thoughts behind." While speaking, he personally took a few blank pieces of paper and handed them over again.

Yang Mingde glanced at the side a few times, a little relieved.

It seems that this seedling is even better than I imagined!
