Chapter 784 Computer Learning

In Zhou Buqi's personal account, there are 80 million. Among them, 50 million was given by parents, and it was Wen Zhixia's reward for giving birth to a child.

This time Mr. Wen went to Shanghai to work, and he would definitely buy a house by himself.

I have already taken a good look at the location, and it was recommended by Shi Jinglin's family. In the luxury residential area of ​​Lujiazui, a 450-square-foot luxury house, not far from the Bund, is near the Town God's Temple, and the price is 15 million.

When it came to buying a house at the beginning, Zhou Buqi subconsciously said Tomson Yipin!

How famous!

The first mansion!

In the end, Shi Jinglin laughed at him, saying that he was corny.

Tomson Yipin's house is priced at more than 40 million, the highest price, but the local top rich people simply don't go there. This is a mid-level luxury house, the only advantage is that it is close to the river and the location is good. The main customer groups are those new rich who are eager to be labeled as wealthy and enter the upper class, as well as entertainment stars.

The real top-notch mansions are all low-key and not exposed, and they are not publicized to the outside world. It is enough to communicate in the circle, and the source of customers is enough. There is also a more important point, that is, if you don't sell to celebrities, you won't be able to do it if you have money.

Zhou Buqi was buried for a while, and he was really powerless to refute.

Compared with the wealthy families in Shanghai, the capital here is really a group of upstarts and old hats.

The next day, Zhou Buqi arranged a task for Ning Yaxian, asking her to help transfer a 5 million card. I took the Fourth Secretary Wang Yaojin with me to meet Shen Xiangyang, the former dean of Microsoft Research.

Prior to this, Xu Liangjie, Wang Haiyang and He Yang came forward one after another, and Dr. Wang Jian was the matchmaker, and the two parties have reached an agreement.

Shen Xiangyang will join Ziweixing.

Level M7, serving as the chief technology officer and concurrently the first dean of Ziweixing Research Institute, responsible for setting up the system and framework of the research institute.

During this recruitment process, Zhou Buqi didn't even show up.

This made him very embarrassed, and he planned to take the initiative to go over and have a talk with him before the other party formally entered the job, which can be regarded as an expression of a polite and virtuous corporal.

Dean Shen's resume is amazing.

He is a genius among geniuses. Xu Liangjie, Wang Xiaochuan, Zhou Feng, Guo Pengfei and others are considered young geniuses, and their talents exploded in their teens. But compared with Shen Xiangyang, it's still a bit worse.

Shen Xiangyang only studied in junior high school for 2 years and high school for 1 year, and was admitted to Nanjing University at the age of 13. At the age of 20, he got a master's degree from the University of Hong Kong, and then went to Carnegie Mellon University to study for a doctorate.

The research direction of the Ph.D. is artificial intelligence!

You know, that was 1996.

Twenty years later, artificial intelligence is a hot industry, but in 1996, artificial intelligence was the unpopular among the unpopular, and everything started from scratch.

He is one of the pioneers in the field of artificial intelligence, and many of the theories he has developed are the basic theories of artificial intelligence.

And more importantly, he did not change his nationality.

At Microsoft Research Institute, he had a big problem with his management, and was successively poached by Baidu and Ziweixing to form two R\u0026D teams. Microsoft headquarters was very upset and wanted to remove him.

How to withdraw?

He was given a higher position, Senior Vice President of Microsoft. Inside Microsoft, there is an iron law, that is, all positions above the vice president can only be Americans.

Shen Xiangyang did not agree to change his nationality, and Microsoft was willing to make an exception for him.

Because even in the United States and Silicon Valley, Shen Xiangyang is the chief scientist in the field of artificial intelligence.

If there is no Ziweixing, he will go to work in the United States after resigning from his post at Microsoft Research. Microsoft is too sincere, and domestic artificial intelligence is still a desert, with no chance at all.

But the appearance of Ziweixing made him see an opportunity!

At Shen Xiangyang's level, the purpose of work is no longer to make money. He has worked for Microsoft for more than ten years, and his personal stock has accumulated tens of millions of dollars.

If he doesn't want to work, he will eat, drink and play all his life, and he will never spend all his money.

The purpose of work is to do something to show personal value and realize personal ambitions.

In the fields of semiconductors, bioengineering, materials science, and basic theory, if you want to achieve higher academic achievements, you can only go abroad. The country is too backward in these fields, and there are several generation gaps. Staying in China, you can only be a college student leading a group of elementary school students to do experiments, do some teaching and educating people, and completely decouple from the world's cutting-edge science and technology.

But the Internet is different, and the sharing attribute is very strong.

Doing the Internet in China, you can still read the top-level literature and master the most cutting-edge technological trends. There are many like-minded people who can exchange views and ideas, and you can still become the person who leads the entire industry.

Being able to lead the entire industry, realize personal value, achieve academic achievements, and serve the country at the same time...why not do it?

"In the past few years, a group of experts in the field of artificial intelligence have emerged in China. I found out later that these people were all brought out by you."

In the coffee shop of Tsinghua Science and Technology Park, Zhou Buqi half-jokingly said.

Shen Xiangyang waved his hand modestly.

But there is no objection.

Because this is the fact that 90% of the more than 1,000 capable people currently engaged in this field in China have worked in Microsoft Research Institute, and they are all brought out by Dean Shen.

After a pause, Shen Xiangyang asked strangely: "You are not a computer major, why are you so interested in artificial intelligence?"

"I know this is the future."

"Good answer."

Shen Xiangyang couldn't help laughing.

Zhou Buqi said slowly: "I don't know if Xu Liangjie told you, Ziwei Star currently has two internal projects, which also belong to the category of artificial intelligence."

Shen Xiangyang said: "He didn't talk to me about business."

Zhou Buqi nodded, "Well, this is a company secret. Let me tell you. One of the projects is personalized content distribution, which uses fundamentally different user information to distribute corresponding advertisements and information through information flow. content."

"Advertisement from Friends Network?"

"Yes, it is mainly Toutiao. This is an internal project of ours. It will be launched in September and will distribute content."

Zhou Buqi briefly talked about the concept of Toutiao content distribution.

Shen Xiangyang thought for a while, and pondered: "If it is this model, simple personalized distribution is not enough, it is not accurate enough. There must be more complex algorithm support, which requires the use of deep computer learning."

"What do you say?"

"Um……"

Shen Xiangyang had some headaches. He was most annoyed to discuss in-depth technical issues with laymen, but the other party was the boss, and he had to explain. After thinking for a while, he said, "Well, you ask me what 5+5 equals. Then I simulate a computer and give You explain. If I'm wrong, you have to give the correct answer, and then ask a few more times."

Zhou Buqi thought it was quite interesting, and said with a smile, "Okay, then I'll ask. Cough, what is 5+5?"

Shen Xiangyang said: "88."

Zhou Buqi was taken aback for a moment, understood what he meant, and corrected him, "No, it's 10. How much is 5+5?"

Shen Xiangyang said: "24."

"No, it's 10. How much is 5+5?"

"17."

"No, it's 10. How much is 5+5?"

"12."

"No, it's 10. How much is 5+5?"

"10."

"That's right. What is 5+5 equal to?"

"10."

"What is 5+5 equal to?"

"10."

Shen Xiangyang made this answer, and then ended the question, "This is the logic of machine learning. Of course it is not arithmetic, but to calculate the user's preference for advertisements or content. In fact, the personalized delivery of advertisements cannot be based on The advertisement itself is based on the content. I have seen the personalized advertisement on Youyou.com, and it is mainly based on the user’s personal information, which is a bit rough and the accuracy rate is not high.”

"Then what should I do?"

"Through machine learning, advertisements and content are bundled. For example, users who read content A like advertisement A, and the two can be connected. This is relatively simple. The more complicated thing is content placement, which needs to be combined with statistical learning and neural networks. Machine learning allows the computer to learn the user's reading habits. Just like the arithmetic problem just now, the error rate is relatively high at the beginning, the more you learn, the smaller the error rate, and the closer to the correct answer, that is, the user's reading habit."

Zhou Buqi was not too convinced, and revealed a little secret, "The personalized advertisement distribution algorithm of Youyou.com is made by Facebook! Well, we are partners."

"That's it..." Shen Xiangyang smiled, "Facebook's technology is not very good either."

"Well……"

What a breath!

Well, this buddy is indeed qualified to satirize Facebook's poor technology.

Zhou Buqi went on to say: "There is another project, we have been working on it for half a year, and we have no idea at all. We sent a very powerful technical expert named Xu Ming, and he can't help it. He was originally from the search business group. technical director, but the project has not progressed, and then he will be transferred to the research institute, you can bring him."

"What project?"

"Intelligent search, personalized search, thousands of pages."

In fact, it is similar to personalized content recommendation, the difference is that this time it is a personalized recommendation for search results.

Shen Xiangyang's face turned serious, "This is much more difficult! It is even more difficult than the personalized advertisement on Youyou, or the personalized content on Toutiao."

"Really? Aren't they all personalized recommendations?"

"The levels are different."

"Um?"

Shen Xiangyang explained: "Technical problems are often two points, one is complexity, and the other is scale. For example, engineering software such as Photoshop and MATLAB are too complicated to be produced in China. Scale refers to How much data. An algorithm may work well when dealing with small data. But when it comes to large-scale data, the algorithm will fail. Just like manual production and mechanized mass production, there is no comparison.”

Zhou Buqi nodded, "Well, big data."

Shen Xiangyang said: "There is one set of big data algorithms, one set of personalized algorithms, and another set of personalized algorithms under big data. This is not a simple 1+1=2 relationship. There is a more optimized design. The concept of intelligent search was mentioned two years ago, but it couldn’t be done.”

Now, the whole world doesn't even understand big data, and don't even think about the derivative algorithms under big data.

Looking at it this way, Lao Shen still has higher technology, wider vision, and clearer cognition!

The project of intelligent search was jointly decided by Xu Liangjie, Cheng Binghao, Wang Xiaochuan and Xu Ming, and they felt that this direction had great potential. But Shen Xiangyang rejected it, saying it couldn't be done.

Well, for a company, the person with the best technology must be the chief technology officer.

Old Shen deserves his name!
