Speaking of brown-skinned guys, he is also quite a legendary figure on the Internet.

Ten years ago, Elon, who had just turned 17, graduated from Harvard University with a degree in computer science, and before that, he had already cracked many systems that were claimed to be the most secure and difficult to hack, such as the corner of the building, the defense department, and so on.

After graduating, Elon joined several companies, engaged in computer artificial intelligence, and designed a number of well-known AI security systems, one of which has an active defense function that makes some of the top hackers helpless, 45% of Internet companies on the entire American continent are using his security system, and he is subjected to about 2.8 billion hacker attacks every day, so it can be said that he protects half of the Internet companies in the Americas.

Elon is now no longer focused on security, and has turned to more sophisticated machine intelligence, namely robots.

"Hey, Elon. ”

Chen Yan prefers this kind of technical master, he walked over and slapped the brown-skinned guy's shoulder like an old friend, "I came up with a more interesting algorithm two days ago, are you interested in coming over and discussing it?"

The corners of Elon's mouth twitched, buddy knows that you have money, but in the field of technology, what qualifications do you have to discuss with me?

Geniuses are mostly arrogant, ordinary people can't understand their world, they don't bother to live an ordinary life, and it's better for everyone not to disturb each other.

Although this guy has just shown his hands and is multi-purpose, on the one hand, he can communicate with people normally without any impact, and on the other hand, he can still remember the self-introduction of more than a dozen people, barely half a genius, such a person has a disgraced qualification to talk to me, so you just pretended to be very close and beat me, I didn't knock off your hand, it was already to give you face.

"You, you... , and a few of you. Chen Yan nodded a few people and said, "Let's go to the conference room to talk." ”

After a pause, Chen Yan turned his head to Musk and Li Xiaoer and said, "Mr. Musk and Miss Li, also go with us, and the rest of us will first assign the work they expect to do in the future." ”

Musk nodded, and after a few words of explanation with the rest of the people, he followed Chen Yan and walked to a spacious conference room.

These new employees have been in Hillstone Technology for two or three days, and they have begun to become familiar with each other, and they know the fields they are good at, their previous resumes, and the positions that have been arranged, so they will not be messy.

When we arrived at the conference room, everyone took their seats.

Chen Yan was on a whiteboard and began to write an artificial intelligence algorithm that he had an idea some time ago, and it wasn't until two days ago that he was determined.

As the handwriting on the whiteboard grew, Elon's face changed from disapproving at first, to slowly shocked, and finally began to frown, looking constipated.

Musk is even more unable to read the handwriting on the whiteboard, but this does not prevent him from guessing the answer from the faces of these computer geniuses from all over the world, and it is obvious that they are all shocked by Chen Yan, to be precise, by the content on the whiteboard.

He thought to himself that he had been invited by Stone's president, Ms. Scarlett, to come to this mysterious eastern country to assist in starting a business, in order to gild the son of a certain bigwig, so that he could obtain some level of bonuses, but he did not expect that this young gentleman was a person with real skills, and he was not a straw bag at all.

"Elon, is the thing on it amazing?" Musk quietly approached Elon and asked in a low voice, "What is it written about?"

"Don't make a noise, old man!"

Elon scolded politely, "You affected me, you know?"

Westerners don't know euphemistic expressions, which are vividly reflected in Elon at this moment, and of course this is also related to Elon's own arrogant nature. With Elon's scolding, everyone else also looked at Musk with unkind eyes, as if they were blaming the old man.

Although Musk just subconsciously asked out loud, he was scolded in front of so many people, and he was still a little embarrassed, so he sat up in a precarious position.

Li Xiaoer on the side was also shocked by Chen Yan's scene, this... It's not like you can't learn anything. She is also a person who knows something about the group of computer geniuses around her, and knows that if she wants to scare them, she really can't do it without any real skills.

"That's it!"

Chen Yan covered the cap of the marker, threw it on the table in the center of the conference room, and then propped his hands on it, and said: "You should know the principle of neural network algorithm, the input layer, the hidden layer, the output layer of a typical three-layer network, each connection line on the network has a weight parameter, how to minimize the error of the parameter, has always been a very tricky problem, until the proposal of the error backpropagation algorithm more than 20 years ago, it can be regarded as an effective solution to this problem, but is this the optimal method?

"Look here, and here...."Chen Yan stretched out his hand and clicked on the two places on the whiteboard, and continued: "When the gradient descends, if a residual parameter is introduced, then in the same case, the original speed will be increased by about 75%. ”

Although Musk can't hear the specific content, he still understands 75% of the numbers!

He knows that in the cutting-edge industry of the Internet, it is a concept to increase a technical index by 75%, and you don't see a toothpaste manufacturer made by a CPU, the products launched every year have increased by 8%, 10%, 15%, and this year has increased by 2 times compared with 5 years ago, etc., what an unbridgeable gap.

"As a simple example, at some point, we may forget what we were just doing, but we can't remember it, what should we do at this time?"

"Give some specific keywords, in line with the scene, the characters, the cause of the incident, etc., and then at a certain moment, you remember. ”

This residual parameter is one such effect. ”

Technicians like Elon and others have understood the ingenuity of this algorithm since Chen Yan named the residual parameters, while Musk and Li Xiaoer suddenly realized it when Chen Yan gave an example.

"Yes, yes, I just can't remember something once in a while, and then I desperately try to remember it, and I can almost recall it. Musk nodded frantically, I understood it when you said that, as for writing so many things, it knows me, don't I know its algorithm?

However, it is also admirable to be able to calculate an ordinary thing through mathematical formulas.

"Is there some better algorithm? I think there are still some algorithms, such as coupling some of the weight parameters on the connecting line, you can have a different structure, this is the four-layer network, or even more layer network scenarios, the complexity of multiple coupling relationships, that is, the ultimate simulation form of the human brain. ”

After Chen Yan finished speaking, he clapped his hands and attracted everyone's attention, "Back then, an ancient song was created with the PageRank algorithm, and later the origin algorithm created a thousand degrees, and the Yanshu company behind it also used the advertising recommendation algorithm to obtain countless funds in a short period of time." ”

"So... , we will use this stone algorithm to create a great company as early as possible. ”
