"Deep structure training is difficult, and traditional methods that are effective for shallow structures do not have much effect on deep structures......"

"That is, in each deep learning design, each layer should be treated separately and trained in a greedy way, after the training of the previous layer, the new layer will encode the output of the previous layer as an input to repeat the training of the upper layer, and after the training of each layer, the parameters should be fine-tuned by using supervised learning (logistic regression desipation algorithm) in the entire network layer......"

Half an hour later, Ma Tian finally finished speaking, took a sip of water, looked at Zheng Shijian and Tang Jiefei in front of him and asked, "Do you have any doubts?" ”

Zheng Shijian & Tang Jiefei: ......

Seeing that the atmosphere was weird, Zheng Shijian said stubbornly: "Mr. Ma, you are talking too profoundly, we don't understand it." ”

Ma Tian sighed, and directly threw out his olive branch: "Zheng Shijian, lead your team to join my Tianyu Xinghai Technology Group Company, this deep learning is indeed a bit complicated, and you will always lag behind foreign countries in your own research!" ”

"Huh?" Zheng Shi was stunned, he didn't expect Ma Tian to recruit him, and he didn't know how to answer for a while.

There are two voices tangled in my head:

One is to immediately agree that only here in Ma Tian can he further his studies in the field of face recognition that he loves;

One is refusal, after all, he wants to move to another city away from the city he is familiar with, and he wants to leave Hanwang Company, which he has paid so much.

Ma Tian saw that Zheng Shijian fell into silence and was not in a hurry, and said to him: "You can think about it, and if you want to stay with me, come to me again." However, let me remind you, the pattern opens up!

Don't just dwell on face recognition. Facial recognition seems to me to be just a small branch of machine learning. ”

Ma Tian didn't say the rest of the words, because when it comes to artificial intelligence in the future, Zheng Shijian will definitely not believe it, including nine out of ten human beings now.

Only the advent of ChatGPT will wake up the world: artificial intelligence is not out of reach.

Face recognition is just a typical example of deep learning applications, Ma Tian doesn't value it, he values the future artificial intelligence track.

This track is too big, it is too slow for him to study alone, and he also needs a partner.

"I'll think about it!" Zheng Shijian did not agree directly, and left with his subordinate Tang Jiefei.

The two sat down at a coffee shop not far from Ma Tian's company.

As soon as he sat down, Tang Jiefei couldn't wait to say, "Brother Ishimi, what are you still hesitating about?" Join Ma Tian! ”

Zheng Shijian glanced at Tang Jiefei, a partner who has been cooperating, and said angrily: "Before you came, didn't you always suspect Ma Tian of bragging?" Now why do you persuade me to say yes immediately? ”

Tang Jiefei was embarrassed, touched the back of his head, and said, "Didn't you believe that Ma Tian was so bullish before you came?" ”

"There is no vanity under the fame! Ma Tian is not a cow wall, can you go to the Zhuang mat platform at 6 o'clock? ”

"Has he ever been on the national media?" Tang Jiefei was surprised.

"Sometimes you really should pay more attention to the information on the Internet, at least to understand the opponent!" Zheng Shijian also obeyed Tang Jie, he was really dedicated to research, and he didn't listen to things outside the window.

"Ma Tian's academic attainments may be even more terrifying than the world thinks, you must know that he is only 19 years old! In your freshman year, you can reach such an attainment in mathematics by pondering casually, and now you can make the face recognition algorithm to the international leading level by pondering it casually, and you are a doctor of Chinese science and technology, and you yourself know how difficult it is! ”

Zheng Shijian looked at the scenery outside the window through the glass window of the coffee shop and continued to sigh, only a genius can describe Ma Tian.

"So what are we hesitating about?" Tang Jiefei asked Zheng Shijian repeatedly.

Zheng Shijian glared at him: "You didn't have a family, I did." Besides, as the vice president and general manager of the company, is it so easy for me to change jobs? ”

Although he said this, Zheng Shi had indeed made up his mind to come to Ma Tian after seeing Tang Jiefei's trouble.

Now he has to go back to discuss with his family, and then communicate with the directors of the company to resign, with his level, he will definitely not be able to run the non-compete agreement, and he will have to pay compensation out of his own pocket.

Zheng Shijian's wife Tang Mengjie had no objection to her husband's decision, and she understood her husband, but comforted her husband and said:

"Iwami, I support your approach and understand you. You once said that you want to bring domestic face recognition to the international leading level, to realize your dream! ”

Zheng Shijian saw that his wife understood him, and he was also relieved, but hugged his wife and said, "Thank you for your understanding!" ”

When mentioning the resignation to the company, it was indeed as Zheng Shijian expected, and it was not so smooth.

Zhong Yingfeng, who is the chairman and executive director, did not agree on the spot: "Iwami, what nonsense are you talking about?" The company can't live without you, besides, you once said that you want to make Hanwang the first company in face recognition in China! ”

"Mr. Zhong, I'm sorry!" Zheng Shijian sincerely apologized, he had already made up his mind to leave.

"What's so good about Ma Tian? It's just a milky kid, only 19 years old, and you, a nearly 35-year-old person, are willing to listen to a 19-year-old person's command? Zhong Yingfeng was very angry because he knew that Zheng Shijian was the mainstay of the company.

Without Zheng Shijian, Hanwang Company can basically be said to be gone.

"I'm sorry, Mr. Zhong, I have already submitted an application for resignation!" Zheng Shijian didn't explain much how powerful Ma Tian was, he had partnered with Zhong Yingfeng for so many years, and he also knew that Zhong Yingfeng's behavior couldn't be listened to, and the non-compete agreement couldn't run away.

In the end, Zheng Shijian paid 1 million liquidated damages before he successfully resigned, and many people in the team also resigned when they saw Zheng Shijian's resignation.

Because they also know that now the company's top technical bosses are Zheng Shijian and Tang Jiefei, and several of them are gone, how can they stay here?

If you can't produce results, you must not be scolded to death by the new executives.

Zheng Shijian also acted as a good man, and personally called Ma Tian to ask if he wanted to recruit people?

Ma Tian pondered for a while, did not directly agree, and made a request for an interview, he wanted to be elite and not indiscriminate, especially the algorithm research involving mathematics.

Zheng Shijian also told Ma Tian's answer to the people behind him.

The people behind him couldn't help but feel apprehensive, they had already heard Tang Jiefei say that Ma Tian was a top technical boss, and they didn't have a score in their hearts when such a big guy interviewed them.

"Don't worry, rest assured, everyone in Ma Tian, including me, is rubbish, if you don't want it, you shouldn't want it!" Tang Jiefei was still joking and was kicked by Zheng Shijian.

"you!" After kicking the funny Tang Jiefei, Zheng Shijian also looked at everyone and comforted, "Prepare well, review algorithms, theories or something, don't be too embarrassed!" It shouldn't be a big problem! ”
