Rebirth of the God-level Xueba

The God-level Xueba Tang Ji of Rebirth was a calm old man as early as when he was 8 years old. network

He watched the data given to Yang Rui by the Computer Department in his eyes, and listened to Xu Zhengping's inquiries in his ears. He was as calm as a mackerel lying on ice—only his eyes were clear and transparent, and the Prove your freshness.

Xu Zhengping was not so calm anymore. Even if Tang Zhong didn't speak, he still commented in a low voice: "The data is very good. If it is drawn as a curve, there are basically no abnormal points."

He doesn't even need to draw curves on the spot, he just looks at the data and can simulate the corresponding curves in his mind, most of which come from experience.

Tang Zhong also nodded slightly, and said: "There are very few abnormal points, and they are uniform, almost negligible."

Outliers, as the name suggests, are points that are different from the norm. And it is usually shown by the curve.

For example, "Xiao Ming eats one chestnut every hour", draw it as a curve, if the abscissa is the unit time, and the ordinate is the total number of chestnuts eaten, then the drawn line will be a standard forty Five shades of gray straight up. Gray is the color of the pencil.

However, if Xiao Ming ate two chestnuts at a certain hour, the point describing this hour will not appear on the line composed of other points, and it will be higher than the standard 45-degree gray upward straight line.

This line is the outlier.

In scientific research, it is quite normal for abnormal points to appear, and they are often the breakthrough point of research.

For example, the curve of "Xiao Ming eats a chestnut an hour" is normal most of the time, and the abnormal point may represent an abnormal situation. For example, Han Meimei went to play with Xiao Ming at noon that day and ate it by the way. A chestnut—discovering this result is enough for ordinary sociologists to publish papers in domestic journals.

If Han Meimei went to play with Xiao Ming at noon that day, and instead of giving Han Meimei the chestnuts, Xiao Ming took two chestnuts out and exchanged them for a **—this result would be enough for ordinary economists to publish papers.

Of course, most of the abnormal points are difficult to explain. Maybe it is an instrument failure, maybe a sampling failure, maybe a sample deterioration, maybe someone sat on the vibrating instrument and made a fuss.

All in all, outliers are something that researchers both hate and love.

Curves, on the other hand, are surprising and uncertain.

Because there are abnormal points, it is normal, and there is no abnormal point, but it is abnormal.

The more complicated the situation, the more so.

after all,

Experimental impossibility simulates reality.

"What's the situation now? Has the experiment been done?" Zhao Lei held up the microphone and began to interview.

"The experiment is complete, and the data still needs to be analyzed." Yang Rui's expression also changed a little.

Such data is also quite new to him. The plasmonic surface resonance that Yang Rui used in graduate school is no longer a cheap mass technology, just like the others.

And it became a mass technology because biotech companies made multiple simplifications of it. Just like a car, a biotechnology company wraps a complex core in a heavy shell, so that ordinary biotechnologists only need to input materials at one end and get results at the other end.

It is also the first time for Yang Rui to use the original parts to splice and conduct the experiment of plasmon surface resonance.

Therefore, Yang Rui doesn't know whether this primary data is correct or wrong.

Zhao Lei was confused by the scene of neither frustration nor joy. She turned the microphone to Xu Zhengping and Tang Zhong, and asked, "What is your evaluation of the experiment?"

"I can't comment on the experiment, because I haven't seen the experiment, what I see now is the result of the experiment." Tang focused on correcting Zhao Lei.

"Then what's your evaluation of the experimental results?" Zhao Lei smiled and changed her words, and turned to Xu Zhengping.

Xu Zhengping would not lie during the interview. He thought for a while and said, "It's data that looks pretty."

"Beautiful data?" Zhao Lei turned her head and asked, "Do you think the data is correct?"

"I haven't done this experiment, so I can't say whether the data is correct or not." Xu Zhengping shook his head, and couldn't help adding another sentence: "But it looks very good."

"It's not necessarily correct, but it looks very, is that what it means?" Zhao Lei repeated Xu Zhengping's words, and the meaning seemed to be much clearer.

Xu Zhengping coughed pretendingly, and said, "I can't tell."

Zhao Lei felt that she had found a news source, and quickly asked, "What do you think might be a problem with the data?"

Xu Zhengping glanced at Yang Rui casually, and found that he didn't seem to care about his conversation with the reporter. For a moment, Xu Zhengping suddenly had the urge to tell. Fortunately, he suppressed it, and said in a calm tone: "The data itself is not good or bad. You can't say that 1 is slimmer than o, and 1 is better data than o. The key is whether the data can show the experimental data. desired result."

This circle is relatively large, Zhao Lei was a little dizzy, she thought for a while, and said: "You seem to be reluctant to talk about the quality of the data, but now that the experiment has just been completed, isn't it the happiest time? You guys Doesn't seem to be happy?"

"There is also the step of data processing, which is also a more troublesome part." Tang Zong grabbed the conversation.

Zhao Lei didn't have much interest in this old man. She turned the microphone, put it on Yang Rui's mouth, and asked, "Student Yang, what are you going to do with these data?"

"Maybe we will hire a professional data team." Yang Rui's answer was beyond everyone's expectations.

Zhao Lei widened her eyes and asked, "Aren't you going to handle it yourself?"

"It's a waste of time for me to process so much data by myself. I'm in biology, not numbers." Yang Rui shook his head and said, "For a professional data processing team, it doesn't take long to process such data. , Do it yourself, it's a pure waste of time."

In fact, Yang Rui doesn't know how to deal with this level of data, even if it's just a few pages, it's fatal.

When Yang Rui was a graduate student, such things were either processed by existing software on the computer, or they were packaged and handed over to data companies.

Of course, the asking price of data companies will be higher, but professional computer software is not cheap, which is also the difference between high-level laboratories and low-level laboratories.

High-level laboratories have to find everything well, and low-level laboratories have to complete everything by themselves.

Zhao Lei looked at Tang Zhonghe and Xu Zhengping inquiringly, and asked, "Is this okay?"

Xu Zhengping didn't say a word, Tang Ji hesitated for a moment, and said: "In foreign research teams, there are often members or teams who specialize in data processing, and there are relatively few such cooperations in our country."

"In other words, Yang Rui's method is quite special?"

"It doesn't matter if it's special or not, the method that can get the result is a good method." Yang Rui finished speaking: "Reporter Zhao, how about we stop here for today's interview? We have to get busy again."

"You are busy with your work, so I will try my best not to disturb you." Zhao Lei felt that there was news, so she retreated to the back, unwilling to leave no matter what.

Dean Liu smoothed things over, and said, "Xiao Yang, you are busy with your own business, so don't worry about it. Beijing TV Station is very powerful. You will apply for a national fund in the future. It is better to be famous than not to be famous, right?"

This is the so-called influence. The influence of the Chinese media was the most prosperous in the 1980s, especially the power of the official media, which is completely worthy of the title of the uncrowned king.

At this time, journalists with a media card travel across the land of China, and the work card can be used as a meal ticket. In the future, there will even be stories of one reporter inside the establishment and dozens of fake reporters outside the establishment, cheating and abducting.

TV stations are journalists with the highest social influence, even if it is only Beijing TV, because of its special geographical location, Peking University cannot be ignored. Although they cannot determine the ownership of national funds, making trouble always has an effect.

Yang Rui couldn't insist on driving the other party away, so he nodded and went back to sort out the materials silently.

Half an hour later, Yang Rui made overseas calls one after another.

The advantage of participating in an international conference is that you can get the communication methods of many colleagues at home and abroad, contact again, do a little favor, or talk about cooperation, at least it can solve the initial trust problem.

Yang Rui doesn't know how far the bio-industry in foreign countries has developed. However, as far as the virtues of capitalism are concerned, as long as you give money, you won't find people to work.

Tang concentrated on watching the pain in the flesh.

The high cost of international calls has never been affordable by normal people. Overseas calls in the 1990s were even more terrifying, often costing more than ten yuan per minute. Although Yang Rui has enough funds, he is still a domestic researcher when he spends so much. unable to adapt.

Finally, no one interrupted Yang Rui.

Zhao Lei was delighted to hear it. She came back from studying in the United States. She listened to Yang Rui's not-so-native but fluent English and contacted all kinds of people.
