Zheng Shijian and others were so excited that they plunged into deep learning, fantasizing that they could also make the same products as Ma Tian, but how could deep learning be so simple.

Deep learning is essentially the construction of machine learning architecture models with multiple hidden layers, and a large amount of more representative feature information can be obtained through large-scale training data. In this way, the samples can be classified and predicted, and the accuracy of classification and prediction can be improved.

The first layer is one or even several feature algorithms, and without sufficient mathematical knowledge, the architecture cannot be built, let alone the model training later.

Zheng Shijian and others added a few all-night classes to barely understand the deep learning methods mentioned in Kilfrey's paper.

Later, I began to use the paper and train the model, and the final result was only 16% accurate, which was stupid.

"Could it be that Ma Tian lied to us?" Tang Jiefei raised his own doubts.

The others nodded in agreement.

But Zheng Shijian vetoed: "Impossible, I have observed the face recognition gate made by Ma Tian and their employees have passed, and the accuracy rate is indeed frighteningly high, anyway, I didn't see any recognition errors."

Also, there is no need for Ma Tian to lie to us, because he can say nothing at all. ”

Everyone was silent, Zheng Shijian made sense, and Ma Tian could not say anything. As for deliberately pointing mistakes and wasting their time, this is not necessary for Ma Tian.

"Could it be that Ma Tian has researched a set of deep learning algorithms by himself?" There is a person who put forward his own opinion, he analyzed, "Ma Tian can post mathematical articles on Nature, and industry insiders also recognize that Ma Tian's mathematics is powerful, which shows that Ma Tian's mathematics is indeed extraordinary, and it is not impossible for him to write his own algorithms on deep learning!" ”

"Makes sense!"

"Agree with that!"

Others nodded in agreement.

Zheng Shijian was silent, because he thought of a possibility: Did Ma Tian predict that they couldn't do it, so he directly told him about the path of deep learning?

"Let's find a way to contact mathematicians in China who are interested in deep learning, and see if we can invite them to take a look!" Zheng Shijian finally decided, now that they are doing so poorly, they can only ask those mathematicians for advice.

Although he thinks that the effect is not great, after all, he is also a doctor of mathematics and computer science from a well-known foreign university.

A few days later, Zheng Shijian and his team members asked several mathematicians who study deep learning in China, and the answers they received were all shaking their heads.

Some mathematicians even questioned them: "You say that Ma Tian has made a face recognition algorithm with a recognition rate of 99%?" You're lying to me, aren't you? ”

Zheng Shi didn't talk nonsense when he saw it, and waved his hand to let his subordinates show him the video posted by Ma Tian's employees on the Internet, and the mathematician on the spot was dumbfounded.

"I can't do it!" After watching the video, the mathematician directly admitted that he couldn't do it, mathematicians have nothing to fake and fake, if they can't they will not be, if they can't they will not do it, if they can't do it, they can't do it!

After a few days, I asked for help in the country, but no one gave a reply, and Zheng Shijian also smoked and sighed in the office.

Although he had been mentally prepared for a long time, he couldn't help but be decadent when the ending was what he expected.

Tang Jiefei suddenly said, "Do you want to ask Ma Tian to help us?" ”

Zheng Shijian didn't speak, but another colleague interjected and asked, "Brother Fei, haven't you ever understood Ma Tian?" ”

"I really haven't looked into it!" Tang Jiefei nodded, he was a programmer who studied with his eyes closed, how could there be those things on the pipe network.

"Brother Fei, Ma Tian is not only a mathematician, he is also the founder of Little Blue Car, and he is worth billions! And he's also notoriously mad, known as a horse maniac! ”

Tang Jiefei heard this silence, he was stupid, and he actually said that he would ask Ma Tian to help.

"But you can't just sit and do nothing, let's continue to do it, I don't believe it, 19-year-old Ma Tian can study it, we can't study it?" Lin Zhanwei in the team threw the information on the table and was unconvinced. Obviously, the mentality was a little unbalanced by the blow.

"If this is hard work, do it if you can? Math won't just won't! Some people disagree with Lin Zhanwei's words, but agree with Tang Jiefei's opinion, it is best for Ma Tian to help, or to ask Ma Tian for advice, which can save a lot of effort.

"Didn't you say that you can't invite Ma Tian? Besides, why did Ma Tian help us, can we impress him as a billionaire by paying for the consultation? ”

"How about not trying?"

……

"Alright, stop arguing!"

Seeing that the team members were arguing, Zheng Shijian also had to speak out to organize discipline: "Study for another week, if there is no direction for another week, I will go to Ma Tian!" ”

Then a week later, Ma Tian met Zheng Shijian and Tang Jiefei in the office.

"Mr. Ma, I'm here to ask for your help today!" Zheng Shijian said with a red face.

Because Ma Tian is too young, he is really a little ashamed to let him, who is nearly 35 years old and is also the boss, come down to beg for help.

Ma Tian looked at Zheng Shi in front of him and saw the two of them, and he also roughly guessed the intention of the two.

"Let's talk about things first!" Ma Tian said in a flat tone.

"Mr. Ma, it's mainly about face recognition, we also learned and tried the deep learning you mentioned last time, but it didn't achieve the same effect as you!" Zheng Shijian completely put down his face and asked directly, "So this time, we mainly want you to see, what is wrong with us?" ”

Ma Tian smiled, sure enough, things were as he expected, even if Zheng Shijian was told the path of deep learning, they would not be able to study the reason in a short time.

"Let's talk about how many layers your deep learning architecture has." Ma Tian asked.

"We currently have 5 layers according to what is written in the paper, and we will optimize the processing of images layer by layer to obtain the transfer of feature values." Zheng Shijian answered truthfully.

"5 floors? It's no wonder that so few can have a high success rate! If I'm not mistaken, you didn't deal with the raw data that can't be separated, right?

Don't use the traditional neural network method to do deep learning, you can flexibly change the writing algorithm to increase the level, as long as the final time complexity is ideal......"

Ma Tian spoke loudly and said the problem of Zheng Shijian and others.

But Zheng Shijian and others didn't even understand the neural network algorithm, and listening to Ma Tian's words was like a scumbag listening to a teacher's lecture.

At this moment, Zheng Shijian and Tang Jiefei, who couldn't understand it, had a feeling that they were really scumbags, listening to Ma Tian talk about a bunch of mathematical formulas and theorems.

I almost took a notebook and a pen to take notes, but Ma Tian, as a teacher, didn't have a board book, so they couldn't even take notes.
