Chapter 489

As early as 30 years old, Tang Ji was a steady old man.

He looked at the data given to Yang Rui by the computer department in his eyes and listened to Xu Zhengping's inquiry in his ears. He was as calm as a mackerel lying on ice - only his eyes were clear and transparent to prove his freshness.

Xu Zhengping is not so calm. Even if Tang Ji doesn't speak, he whispers: "the data is perfect. If you draw a curve, there are basically no outliers."

He doesn't need to draw a curve on the spot. He just looks at the data and can simulate the corresponding curve in his brain. Most of this comes from experience.

Tang Jianji also nodded slightly and said: "the abnormal points are very few and even, which can almost be ignored."

Outliers, as the name suggests, are those that are different from normal ones. And it's usually represented by curves.

For example, "Xiao Ming eats one chestnut an hour" and draws it into a curve. If the abscissa is unit time and the ordinate is the total number of chestnuts eaten, the drawn line will be a standard 45 degree gray upward straight line. Gray is the color of a pencil.

However, if Xiao Ming eats two chestnuts in an hour, the point describing the hour will not appear on the line composed of other points, and it will be higher than the position of the standard 45 degree gray upward line.

This line is the outlier.

In scientific research, the occurrence of abnormal points is a normal thing, and it is often a breakthrough in research.

For example, the curve of "Xiao Ming eats a chestnut an hour" is normal most of the time, and the abnormal point is likely to represent an abnormal situation. For example, Han Meimei went to play with Xiao Ming at noon that day and ate a chestnut by the way - finding 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, Xiao Ming did not give Han Meimei chestnuts, but took two chestnuts out for a condom - finding this result would be enough for ordinary economists to publish papers in SCI.

Of course, most of the abnormal points are difficult to explain. Maybe it's instrument failure, maybe it's sampling failure, maybe it's sample deterioration, maybe it's someone sitting on the instrument shaking desperately.

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

And the perfect curve, it is amazing uncertainty.

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

The more complicated the situation is, the more so it is.

After all, experiments can't simulate reality perfectly.

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

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

Such data is also quite new to him. The plasma surface resonance used by Yang Rui when he was in graduate school is already a worthless mass technology, just like PCR.

And the reason it has become popular technology is that biotech companies have multiple simplifications. Like cars, biotech companies wrap complex cores in multiple shells, so that ordinary biotech personnel 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 carry out the experiment of plasma surface resonance.

Therefore, Yang Rui does not know whether this primary data is correct or wrong.

Zhao Lei was puzzled by the scene of no depression or exultation. She turned the microphone to Xu Zhengping and Tang Jianji and asked, "what's your evaluation of the experiment?"

"We can't evaluate the experiment because we don't see the experiment. What we see now is the result of the experiment." Tang focused on correcting Zhao Lei.

"What do you think of the results?" Zhao Lei changes her words with a smile and faces Xu Zhengping.

Xu Zhengping won't lie in the interview. He thought for a moment and said, "it's beautiful looking data."

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

"I haven't done this experiment. I can't say whether the data are correct or not." Xu Zhengping shook his head and added: "but it looks perfect."

"Not necessarily right, but it looks perfect. Is that what you mean?" Zhao Lei repeated Xu Zhengping's words, and the meaning seemed to be much clearer.

Xu Zhengping pretended to cough and said, "I can't say it well."

Zhao Lei felt that she had found a news point and asked, "what do you think might be wrong with the data?"Xu Zhengping glances at Yang Rui and finds that he doesn't seem to care about his conversation with reporters. For a moment, Xu Zhengping suddenly has the impulse to tell. Fortunately, he suppressed it and said gently: "the data itself is not good or bad. You can't say 1:0 is slim. 1 is better than 0. The key is whether the data can show the desired results."

Zhao Lei was a little dizzy. She thought for a moment and said, "you don't like to talk about the quality of data, but now that the experiment has just been completed, isn't it the happiest time? You don't seem to be happy? "

"There are also data processing steps, which are also troublesome." Tang Ji snatched the words.

Zhao Lei is not interested in this old man. As soon as the microphone turns, she slips it into Yang Rui's mouth and asks, "classmate Yang, how are you going to deal with the data?"

"Maybe we'll hire a professional data team." Yang Rui's answer was unexpected.

Zhao Lei opened her eyes and asked, "don't you deal with it yourself?"

"It's a waste of time for me to process so much data myself. I'm a biology player, not a digital player." Yang Rui shook his head and said: "for a professional data processing team, it won't take long to process such data. It's just a waste of time for us to do it ourselves."

In fact, Yang Rui can't process data of this level. Even if it's just a few pages, it's fatal.

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

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

All the high-level laboratory samples should be found, and all the low-level laboratory samples should be completed by themselves.

Zhao Lei looked at Tang Jianji and Xu Zhengping like consulting, and asked, "is that ok?"

Xu Zhengping didn't say a word. Tang hesitated for a moment, and said: "in foreign research teams, there are often members or teams specialized in data processing, but there are few such cooperation in China."

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

"It doesn't matter whether it's special or not. The way to get results is a good way." Yang Rui said, "reporter Zhao, how about that's all for today's interview? We have to get busy again. "

"You're busy. I'll try not to disturb you." Zhao Lei felt that there was news. She stepped back and didn't want to go.

Dean Liu, with a happy ending, said: "Xiao Yang, you're busy. Don't worry about us. Beijing TV station is very powerful. If you want to apply for national fund in the future, it's better to be famous than not, isn't it? "

This is the so-called influence. The influence of the Chinese media was the most prosperous in the 1980s and 1990s, especially the valiant official media, which is worthy of the title of the king without a crown.

At this time, a reporter with a media card walks in China, and his work card can be used as a meal ticket. In the future, there will even be a story of a reporter inside the establishment, taking dozens of fake reporters outside the establishment to wander the rivers and lakes and cheat.

TV station is the most influential reporter in the society. Even if it is only Beijing station, because of its special geographical location, Peking University can not be ignored. Although they can't decide the ownership of national funds, making trouble always works.

Yang Rui can not insist on driving away the other side, nodded and quietly went back to sort out the information.

Half an hour later, Yang Rui began to make all the overseas calls.

The advantage of attending an international conference is that you can get many ways of communication from peers at home and abroad, contact again, do a little help, or talk about cooperation. At least you can solve the initial trust problem.

Yang Rui doesn't know where the foreign biological industry has developed. However, as far as the virtue of capitalism is concerned, as long as you give money, you won't be unable to find people to work.

Tang focused on the pain of flesh.

The high cost of international phone calls has never been affordable to normal people. The overseas phone calls in the 1980s were even more terrible. They often cost more than ten yuan per minute. Although Yang Rui has enough funds, domestic researchers can't adapt to such extravagance.

Finally, no one interrupted Yang Rui.

Zhao Lei is very pleased to hear that. She is a person who came back from studying in the United States. Listening to Yang Rui's poor but fluent English, she can contact all kinds of people. She has a sense of intimacy.

In another half an hour, Tang finally couldn't stand it. He left the lab and made two phone calls secretly.
