in the office.

Sigbar and Alvin worked on the paper together.

He just read the introduction and immediately realized that the paper might be helpful in improving the data model and improving the algorithm.

Sigbar is different from Alvin, he will not study it slowly, but simply call a few people over, "Everyone put down the work at hand and take a look at this first." ”

This look is more than two hours.

They also concluded, "This way of helping to build data models is indeed feasible." ”

"In this way, more data is more efficient and accurate, and when there is less data, it is not applicable."

"The difficulty was in the construction of the original model, and we couldn't overturn the original structure and reconstruct it in this way."

"The method is new, but it is not easy to apply."

Sigbar leads the core algorithm group, and several employees under him can be said to be the elite of the R&D center.

After careful study and discussion, they have a basic understanding of the construction method described in the paper, and can infer the situation after use.

Finally, Sigbar concluded, "Generally speaking, the more data you have, the lower the accuracy of data analysis. ”

"This model is no exception, but the speed of accuracy drops is very slow, for example, 100 data, we use a construction model, 99.9% correct. If it's 10 billion pieces of data, it's 80 percent. ”

"The algorithm built using this model has only 90 percent accuracy for 100 data, and the accuracy rate for 10 billion data will not be less than 85 percent."

"This way of building a model is indeed very meaningful, but in terms of application, it still needs to be studied slowly."

"In the papers, many of them are just a general introduction, but the method is fine. We might be able to give it a try, and if there's a suitable next project, we can adopt this approach. ”

……

Amriken, San Francisco, California, Google R&D Center, Data and Data Applications Lab.

Blake Jones is sitting in his office, he has been working at Google for eleven years, working on projects such as algorithm customization, Android system improvement, and artificial intelligence, and is an extremely experienced and highly skilled algorithm engineer.

Now he looks at the ordered computer journals.

There were three papers in a row that attracted his attention, and he looked at it carefully for a long time with a twisted brow, and felt that the method mentioned in it was very interesting, so he simply took a photo and shared it with his colleague group, "Let's take a look at this, the new data model construction method." ”

"I took a look at it, and it was very interesting."

Soon.

A few colleagues who didn't order asked Blake Jones to take a few more pictures and send them a few more pictures, preferably with all the papers.

Blake Jones tried the image extraction text function, and found that when it came to math content, a lot of it was extracted, and he simply took pictures one by one with a bitter face.

This matter was supposed to be in the past.

In the afternoon, the technical manager found Blake Jones and the others, and said seriously, "Blake, I also read what you posted, it's very interesting, and importantly, maybe valuable." ”

"We have to take it seriously."

"Guys, put down what you're doing and work together, this method might improve our efficiency......"

……

The same thing happened in the R&D centers of several large Internet companies, and even the data control centers and information centers at the national level.

When a new way of building a data model emerges, which can be applied to massive data analysis work and improve efficiency and accuracy, it will definitely be valued by Internet-related companies and information centers.

Just a day later, news was received in the country.

Feng Youli, director of the big data R&D center and technical department of Abayun Group Co., Ltd., received a report from his foreign employees.

In the new issue of Computer Mathematics and Information Engineering, a new method of data model construction is introduced.

"It's worth paying attention to!"

Emphasis is placed on the employee report on the situation.

Online ordering and browsing will be delayed by three days, and there is no way to see it in China for the time being, but there are many ways to bypass the delay.

Feng Youli quickly got the full content of the paper, and he found several high-level technical employees to analyze it carefully.

At the same time, Feng Youli had an idea, "The author of the paper is a faculty member of Xihai University, and he can research a new way of building data models, and he must be an extremely good talent." ”

"The easiest and most straightforward way is to invite him to work in Abayun."

"He is a talent, and what Abayun needs most is talent."

"If this method is feasible, it will be the most perfect for him to lead the correction and improvement of the relevant applications and underlying algorithms."

……

When the influence of the paper slowly fermented, Wang Hao was not affected for the time being, and he and Zhang Zhiqiang completed the research of 'Cauchy non-negative matrix factorization expression' together, and the paper was also handed over to Zhang Zhiqiang for publication.

Then he was idle.

He sat in his office drinking coffee, chatting with other people, talking about gossip circulating at school, and even talking about men and women.

The next day was Thursday, and the morning was still very quiet.

Wang Hao opened the system and glanced at task two, and unsurprisingly found that the inspiration value was only '33' points, "It seems that research and research are different." ”

"Even for research of the same difficulty, the speed at which inspiration is obtained is not the same."

"In the study of Fourier transform, the growth rate of inspiration is relatively fast, while in the study of the 'Cauchy problem', the growth rate of inspiration is slower......"

"There are probably a lot of factors involved, such as the content of the teaching, the situation of the students, the thinking of the students, and so on."

Wang Hao sighed lightly, and simply studied the study of 'partial differential equations', and the inspiration value of the research of 'partial differential equations' has exceeded seventy points, and when it reaches this value, it is almost time to start researching.

However, progress has been slow.

Two hours of dedication can almost be described as 'no gain', not even a single problem has been solved.

"It's hard!"

"Inspiration is not enough, it means that the knowledge and ideas are not enough to support the completion of the research. It's too hard to solve the problem! ”

He simply changed jobs.

Write a lesson plan!

Other teachers are focused on doing research and development and writing papers, but for Wang Hao, teaching is the fundamental, and he hopes to continue to improve in teaching, not to study how to make students understand the content of knowledge, but to guide students to think more.

This is critical.

When students can think more, they will be able to give back more knowledge and inspiration.

"Guide students to think more about ......"

"How?"

"The topic is better, if it is about basic knowledge, how to increase the content that guides students to think?"

I couldn't think of anything for a while.

Wang Hao inquired with a few people in the office, and asked Zhou Qingyuan, and learned about an old professor--

Wang Huanxin.

Wang Huanxin is fifty-nine years old, but he is still only an associate professor, mainly because there is no breakthrough in scientific research, most of the papers he has published are related to teaching, he is recognized as an excellent old teacher in the school, and the students have a good evaluation of him.

It's just, alas.

No matter how good he is in teaching, it is difficult to get promoted, and he has not been promoted to full professor until now.

The people in the office had all kinds of gossip, and Zhu Ping said with great certainty, "The school is planning to take advantage of the popularity of 'eliminating paperism' and want to mention Wang Huanxin a full professor, a teaching full professor." ”

This is extremely rare.

Wang Hao knew that Wang Huanxin's teaching ability was very strong, so he went to listen to Wang Huanxin's class in the afternoon, and found Wang Huanxin after class to discuss teaching issues.

Wang Huanxin was very enthusiastic about Wang Hao, and he said with emotion, "I really didn't expect that someone would be able to talk to me about teaching." ”

"Now young teachers like you only care about scientific research and papers, but the most important thing is to teach students, and teaching students well is the first priority!"

"If you do well in scientific research and write a good paper, it is better to be a researcher in a laboratory than to be a writer."

Wang Hao nodded in agreement, "I just hope to teach students well and make the course more efficient." ”

Wang Huanxin was indeed very happy and took the initiative to share his teaching experience.

Wang Hao put forward the question of 'how to guide students to think', and he also gave several examples to illustrate in detail.

The two of them talked for more than an hour.

It wasn't until he found that Wang Huanxin seemed a little tired, Wang Hao left after thanking him, he felt that he had gained a lot, and he also learned several tricks for the problem of 'guiding students to think'.

Together, these can even be used to write a 'teaching' essay.

However, his thinking is still dominated by logic, and when it comes to making summaries and writing papers, he immediately thinks of a question, "Guiding students to think more may not be better than the teaching effect." ”

"For the teaching of basic content, as long as students remember and understand, it is enough, so how to judge and guide students to think can bring more knowledge and inspiration? Maybe the original teaching method was better? ”

This is uncertain.

Wang Hao thought of a way to judge, "If you just give a lecture to a few students, the students' IQ is relatively average, and it is difficult to understand the content of knowledge." ”

"Using two methods to compare two pieces of knowledge with similar difficulty, maybe you can know which method is better?"

"So who to look for? Stupid student, stupid student......"

Wang Hao continued to chant the words 'stupid student', and the figures of two girls, one fat and one thin, suddenly appeared in his mind.
