On the same day, Cao Dongming took Wang Hao to visit the Institute of Aeronautical Materials, talked about the problems related to the report, and reminded him not to talk about the research done by Peng Hui's team, which was also for the sake of confidentiality.

Even the Institute of Aeronautical Materials, for projects that have just entered the national major secrets, they cannot talk about it everywhere at will, and it depends on the follow-up evaluation of the project and the opening of data.

They came back to the problem of reporting.

Wang Hao has been prepared for this, and he is ready to talk about the methods used in the data analysis process and the calculation methods finally studied.

The final calculation method is the classic place, and it can be summarized together to write a top data mining paper, which is naturally not a small achievement.

This kind of achievement is relatively practicable, especially for the research of titanium alloy materials, and is generally not published.

Now I can make a small report at the Institute of Aeronautical Materials, which can be regarded as letting more people know about my research, and it is also a small contribution to the development of the national materials field.

Cao Dongming attaches great importance to Wang Hao, and he arranged the time of the report at nine o'clock the next morning, which can be said to be the 'golden time' during working hours.

At the same time, in order to make the report more 'lively', he sent messages in several chat groups of the Institute of Materials, and especially talked to several experts in the calculation of materials in the Institute of Materials.

It's a pity.

Cao Dongming's face doesn't seem to be so big.

The next day, Wang Hao came to the Institute of Aeronautical Materials and entered the small conference room to make a report in advance, only to find that there were only a dozen people sitting below.

He thought he had come too early, so he asked Cao Dongming in particular, and when he saw Cao Dongming's embarrassed expression, he already knew the answer in his heart.

"Okay, a dozen people are a dozen people."

"Not a lot!"

"After all, all of them are top-level experts."

Wang Hao comforted himself, he didn't care very much, after all, it was for Cao Dongming's sake that he was invited here to make a report, and he could leave after making the report.

As for how many people listened, it didn't matter much at all.

He still wanted to open it.

After entering, I shook hands with everyone and got to know each other, and I also felt that the Institute of Materials still attached great importance to it, because there was an academician who came here, and he was also the vice president of the Institute of Materials.

That's Qu Shi Gang.

Qu Shigang is more than 50 years old, is the youngest academician of the Institute of Aeronautical Materials, he was originally a doctor in the direction of computational materials, after returning from studying abroad into the Academy of Materials Sciences, began to lead the team to do research on aluminum-magnesium alloys, and was soon promoted to the director of the aluminum-magnesium alloy research laboratory.

Later, it entered the field of composite materials and achieved great results.

At the end of last year, Qu Shigang led the team to complete a major project of composite materials, and now the beginning of the year is relatively leisurely, and he is also preparing for a new project.

When I saw Cao Dongming sending a message inviting people to listen to the lecture on data mining, I also came over with curiosity.

In fact, his curiosity was reversed.

Recently, Qu Shigang has been relatively idle, and he has no projects in his hands, just responsible for some materials institute affairs, and he often goes to watch the news.

Then he noticed Wang Hao.

For a period of time, good multimedia were reporting on Wang Hao, and also reporting the 'story he had to tell' with Donggang University, and later it became Donggang University's self-examination, and it turned out that the alloy laboratory incident had nothing to do with Wang Hao.

Qu Shigang also paid careful attention to the investigation announcement issued by Donggang University, and the responsibility was attributed to another core researcher in the laboratory.

"Typical problems, find the people below to take responsibility!" Qu Shigang looked at the announcement with emotion, and at the same time he also noticed the sentence 'Professor Wang Hao does not understand material research'.

At first, Qu Shigang didn't care about it at all, and he read the news after reading it.

But he has a very good memory.

When he heard Cao Dongming say that he invited Wang Hao to give a report, he asked a special question and knew that it was indeed Wang Hao from Xihai University.

Qu Shi just went to flip through the report again, and felt that Cao Dongming was very unreliable, and invited a young mathematics professor who didn't understand materials to come to the Institute of Materials to give a report on data mining in the field of materials?

Even if this young mathematics professor has completed a lot of top-notch mathematical research in half a year, data mining in the field of mathematical theory and materials are fundamentally two different directions, and there is a correlation to say that there is, but the correlation is very, very low.

So the form has just come.

He did come with curiosity, but that curiosity was 'reversed'.

……

Wang Hao didn't know that the 'Academician Qu' in the audience listened to the report with reverse curiosity.

Although there are only a dozen people in the conference room, there is an academician among them, who is still the vice president of the Institute of Materials, and the rest are all researchers and professors, and the lowest is also an associate researcher level.

Then he started the report.

Wang Hao's opening remarks were very interesting, he said, "I'm also nervous standing here, to be honest, I don't understand aviation materials, I'm a complete layman, I just have some research on data mining." ”

"In the next explanation, if there is a problem, everyone must remind me."

After telling the truth, he began his own report, first explaining from the usual means of analysis.

There are several conventional methods of data mining in the field of materials, including detailed analysis of experimental data, column charts, probability studies of number distributions, and so on.

These are also routine methods of data mining, and are used for analysis in most related fields.

Wang Hao's explanation is relatively more in-depth, and he gave several very direct examples, including the data of the titanium alloy manufacturing process, which is easy to understand.

"The Gift of Teaching" also played a significant role in increasing the understanding of others by 40 percent.

Everyone in the audience felt that after listening to Wang Hao's explanation, they seemed to have a deeper understanding of the methods used countless times.

Suddenly, they were even more serious.

Qu Shigang couldn't help but praise secretly in his heart, "There are indeed some levels." These conventional analysis methods are explained like textbooks. ”

Cao Dongming sat next to Qu Shigang, and he didn't have much interest in data mining and analysis at all, because he didn't do research in this direction.

Now it's just a matter of making up the numbers.

However, he is very confident in Wang Hao, or in other words, everyone who knows about Peng Hui's team project will have great confidence in Wang Hao.

The results of Peng Hui's team can no longer be described as lucky.

The study of the compressive strength of β-type titanium alloys may lead to the creation of materials with a tensile strength of more than 1,500 megapascals by luck, but it is simply impossible to manufacture materials with a tensile strength of more than 1,600 megapascals.

Not to mention, the probability of more than 1,700 megapascals is much smaller than winning 100 million.

So, as Peng Hui said, or what they saw with their own eyes, Wang Hao played a crucial role in the conclusions reached by the analysis of the experimental data.

From this, it can be judged that Wang Hao must be the top expert in the relevant field.

When he found that everyone in the conference room was listening very carefully, including Academician Qu Shigang, who was becoming more and more involved, Cao Dongming felt very normal.

That's a top expert in data mining, can the explanation not be attractive?

In the conventional analysis methods, Wang Hao spent half an hour to explain, and then entered the critical stage, he began to explain a new calculation and analysis method, "This method is a combination of the previous methods, but also a new method, which can maximize the elimination of data interference and expand the difference." ”

"The most basic of them is the use of a discrete mathematical approach."

"Let's take a look at ......"

As the explanation progressed, the people in the room listened more attentively, because they found that the content became much more difficult and it was not easy to follow the pace and understand.

At this time, it also showed Wang Hao's professionalism, he was not in a hurry to explain mathematics, deduced the calculation step by step, adopted the final conclusion, and then transformed it into a calculation method.

"In this way, the difference in the data can be magnified. Even small differences can be made noticeable by calculation. ”

"After that we can analyze the ...... by graphing"

When it comes to the graph analysis step, it is even more difficult to keep up with the understanding.

When it comes to advanced functional theory, more than half of them can't keep up because they don't have a relevant theoretical basis.

But even if they couldn't keep up, they were still listening carefully, because they found that the method explained by Wang Hao was indeed very subtle, and it was very suitable for the experimental analysis of alloy materials.

This method may not be effective in other data mining fields, but it is very helpful for the study of alloy materials.

Later, Wang Hao spent another half an hour to finish, and he tried to explain in more detail.

But in reality, the effect is small.

If you have enough basic knowledge, it will not be much of a problem to understand the content, but there are a bunch of material computing experts sitting in the audience, and it is not so easy for them to understand some advanced discrete mathematics and function theory.

However, many people don't understand and are not in a hurry, because the report will have a detailed record, and they just need to get the record and do research slowly.

End of report.

The people in the conference room were much more enthusiastic than they were at first.

Qu Shigang completely changed his opinion of Wang Hao, and he secretly scolded Donggang University many times in his heart, "Why don't you understand material research?" At this level, you still don't know about material research? ”

"This is a data mining expert in the field of alloy material research and development, and it is definitely a top expert level!"

Qu Shigang also opened his mouth to ask a question that he didn't understand.

Wang Hao also patiently explained, in fact, Qu Shigang's problem is the lack of foundation, he doesn't understand the analysis of advanced discrete mathematics, Wang Hao said some basic content, and then he can understand it immediately, knowing that he doesn't understand advanced mathematics, he won't understand the problem, so he won't continue to ask questions.

The same goes for everyone else.

At this time, Cao Dongming asked, "Professor Wang Hao, you have given several examples for the research and development of titanium alloys, so can the latter calculation method be directly used in the experimental data analysis of the research and development process of titanium alloy materials?" ”

"It depends."

Wang Hao replied, "There are some situations that are okay and some situations that are not, if you understand all the content and compare the specific research content, you can analyze which ones can be used." ”

He shook his head, "There are so many areas involved in this area that I can't explain them all, so let's give a simple example." ”

"For example, when it comes to melting temperature control, it's not just about letting the metal melt, and sometimes, with the right temperature, the alloy strength can be higher."

"Look at this example......

Wang Hao began to explain patiently again, and it took more than ten minutes to explain.

Everyone in the audience listened very carefully, and when Wang Hao gave an example, they understood the use of the method better.

At least in the melting temperature control part, we know that relevant methods can be used for analysis.

After Wang Hao finished explaining, someone immediately stood up and asked, "Professor Wang Hao, can you talk about the cooling and quenching process......

"This ......"

Wang Hao suddenly hesitated.

It's not that he doesn't want to talk about it, but he hasn't completed the 'general method of β experimental data analysis of titanium alloys'.

[Inspiration value: 86.] 】

The data can already explain everything, some processes, he has been able to explain directly, and some processes need to be carefully studied.

Wang Hao looked at the time and said with some regret, "When I came yesterday, Cao Dongming told me about the problem of general analysis methods for titanium alloy experimental data, but I just thought about it roughly and did not complete the research, so I have no way to explain them one by one in many processes." ”

"It's important for everyone to understand this method of analysis, and that's why I'm here to give a report."

After Wang Hao finished speaking, he walked off the stage.

There was also applause in the conference room, but everyone was very awkward, they felt like they were watching one, just seeing the high-tide stage, and they were looking forward to what was going to come......

The author is too - prison!

Don't write it!

It's a feeling of being so depressed that it's about to suffocate to death!

Not to mention other people, Qu Shigang has this feeling.

Wang Hao just talked about the core content, that is, the analysis method he researched, how to use it in the data analysis of what process.

It's important to know the method, and it's even more important to know where the method can be used.

Outcome?

Do not say!

Qu Shigang had an urge to vomit blood, but Wang Hao had already said that he had not completed the research, and he had no way to ask the other party to say anything.

Next, Cao Dongming entertained Wang Hao to have a meal in the canteen of the Materials Institute.

Looking at the time, Wang Hao left.

His ticket was at three o'clock in the afternoon, and he went back to the hotel to pack up and hurry to the airport to catch the plane.
