Hammer of Technology

For Ning Wei, he didn't think the sweeping scandal was a very confusing thing.On the contrary, the research in number theory is the most troublesome for him.

The reason why he always thinks that he has only made staged progress is because compared with the judgment and analysis of big data, solving its movement and exchange capabilities is only the most basic part.

This involves more basic issues, such as the precise definition of data in mathematics, and it must be given a mathematical expression, such as the number of its number field type and its physical dimension.At the same time, the abstract expression of data and its relational model also need to be rebuilt.

For example, if big data is defined as a large-scale heterogeneous typed quantity that is different from untyped discrete numbers in terms of quantity and quality, diversity, storage, retrieval, extraction, calculation, semantic cognition, maintenance and processing superstructure.Then, before constructing the whole theory, it is necessary to have a strict definition of this superstructure, so that the whole big data system can be described in mathematical language.

The difficulty involved in this can be imagined.

The basic characteristics of big data are unstructured, heterogeneous, monotonous growth, non-descriptive, mixed/fuzzy semantics, and consistency decays or entropy increases with time. These inherent complexities and extremely large-scale multi-dimensional hyperstructure objects , is extremely difficult to define.

Professor Robert's paper made him think of another possibility.

Since it is too difficult to define from a mathematical point of view, why can't we solve this underlying problem from the perspective of a machine.

If you substitute the perspective of a machine, Ning Wei has summarized the structure of data defined by category and source

Observational data can include facts, states, and behaviors; facts can be divided into characteristics, ordinal numbers, cardinal numbers, counts, and quantities; states can be divided into existing forms, structures, and state changes; behaviors can be broken down into interactions, norms, cycles, distribution, frequency.

Inferring data includes analogies, relationships, measurements, semantics, mathematics, statistics, and composition.

Among them, analogy includes similarity, comparison, and equivalence; relationship includes association, causality, mapping, sequence, and concurrency;

Measurements include quantification, qualification, scaling, normalization, weighting, classification;

Semantics include physics, experience, abstraction, mathematics, rules, properties;

Mathematics includes linear, nonlinear, polynomial, analytical, differential, integral, refinement, functional systems;

Statistics includes probability, norm, deviation, distribution, condition, random process;

Composition includes interpolation, extrapolation, exponents, power functions, factorials, Cartesian products, searching, sorting, combining, permuting, and system fusion.

In addition to engineering data, social data, etc...

The divergence of inspiration took Ning Wei too much energy and time. He locked himself in the room for two whole days, and he didn't even have time to pay attention to the impact of the so-called scandal on him.

In fact, when entering the research state, it is easy to have the illusion that all those messy things are over.

Until a phone call came directly from China.

"Ning Wei, what's going on between you and that Swedish princess?" Director Tian's voice sounded a little tired to him.

"Ah? How did you know this?" Ning Wei was a little surprised.

"The domestic self-media is going crazy. These two days are full of news about your relationship with the Swedish princess. I, an old guy, have just received a few calls asking about you, and you Jiang University. The professor's phone number." Tian Yan said angrily.

Ning Wei frowned.It's not because of the tutor. The key is that since the tutor already knows the news, there is a high probability that Jiang has already seen it. What will she think?

This is what Ning Wei cannot tolerate.

"Director Tian, ​​I have nothing to do with that Isabel. I will explain it to you after I go. I still have some important matters here."

"It doesn't matter. It's not like I want to take care of your private affairs, but some problems are more complicated after all. You should think about it. If you have something to do, go ahead and do it first. I won't disturb you."

After hanging up the phone, Ning Wei turned off the data structure construction he was doing, and started to log on to the domestic website to find out what happened in just two days.

Sure enough, the Internet is full of pictures he found on Google and various short stories written according to the pictures.

What puzzled him the most was that a bunch of booers kept praising him for winning glory for the country. The bottom line of winning glory was too low. Talking to a woman for a few words and taking a photo together would count as winning glory?

Ning Wei was almost annoyed.

Then he probably understood the reason why the news would become more and more popular.

The answers of several professors who participated in this meeting were wrong, and the ambiguous smell could rush out through the screen.

Well, the messy news on the Internet made Ningwei feel depressed, so he closed the webpage and began to quietly think about how to deal with the whole matter.He can probably analyze Jiang's mentality, and she probably understands what this girl thinks after seeing the news, so from the perspective of thinking patterns, he can empathize, switch roles, and then bring in...

The brain was running fast, curves were formed in the brain, and then disappeared, especially in the short communication with Jiang Chenshuang, every reaction of the girl became the basis for judging the result.

Ning Wei quickly made up his mind and looked at the computer. It was already 08:30 in the morning.China time is exactly twelve hours from Montreal time, which means that it is 10:30 Beijing time.

Ning Wei picked up the phone without hesitation and made a call.

The call was connected, but no one answered, and it automatically hung up after 40 seconds. Ning Wei called again without hesitation, three times in a row...

When the phone was connected, Ning Wei said without hesitation, "Hi, I'm Ning Wei."

"Ah? Are you Dr. Ningwei?"

……

Rewinding the time to a few minutes ago, the location spanned thousands of miles and focused on the female dormitory at No. 33, Building 202, where the finance major of Capital University is located.

A few girls were chatting casually while busy with their respective affairs.

"Sister Yuxuan, do you think the rumors about Dr. Ning on the Internet are true? Doctors from Yanbei University are in love with Montreal. Seeing our school's name on such a title makes me feel quite horrified." The most in the dormitory The lively and youngest Wang Jiaying looked at her phone and casually chatted with the girl at the next table.

"Who knows? But what I read online is a bit confusing. But looking at the photos, the two may have some relationship." Xi Yuxuan also responded casually when asked.

"Hey, Senior Ning's salary is comparable to those of big stars. Hey, by the way, Chen Shuang, why haven't you taken a part-time job playing the piano these two days?" Jiang Chenshuang asked.

All the girls in the dormitory knew about Jiang Chenshuang's part-time job playing the piano, otherwise it would be impossible to explain the fact that several new clothes had been added.Of course, I don't know anything else.

After all, Jiang Chenshuang didn't want to say it, and no one would force it.

"Oh, the boss gave me a vacation these days." Jiang Chenshuang turned her head and smiled, and replied softly.

She didn't care much about the messy news on the Internet, but the news about Ning Wei still inevitably reached her ears.

This once made her feel a little sad and lost, but after this little emotion, she felt a little inexplicably relaxed, and it was actually good to be able to silently bless such an outstanding boy who had appeared in her life.

In fact, she really wanted to agree to Ning Wei that night, there was no other reason, probably because she felt from Ning Wei that apart from the overbearing when he sent her back to the dormitory that night, there was also the fact that he had not disturbed her for more than a month. Her respect, this feeling is very heartwarming, so she wants to give herself a chance.

It's just that the opportunity seems to have flown away now, but Jiang Chenshuang doesn't have much regret, after all, the two of them didn't start at all, let alone she thinks that Ning Wei really deserves better.

It's actually quite good to regard the little thoughts during this period as a precious memory in this life.

"Your boss is really nice, and you can often take vacations." Wang Jiaying said with emotion.

"Well, he is quite nice. My water bottle is out of water. Do you need to fetch water? I went to fetch water for you?" Jiang Chenshuang asked.

The dormitories of Yanbei University have several drinking fountains that provide boiling water 24 hours a day, which is probably one of the benefits of the dormitories.

"No, I still have half a bottle."

"I don't need it either!"

"Well, then I'll go first."

After speaking, Jiang Chenshuang left the bedroom with a water bottle, and her old-fashioned Samsung mobile phone was placed on the table.

As a result, not long after leaving the house, the phone rang.

The two girls who were still in the dormitory ignored it until the phone automatically hung up because no one answered, but within two seconds, the phone rang again.

"Jiaying, why don't you pick it up and ask if there is something urgent? If you are in a hurry, you can send the phone to Chenshuang." Xi Yuxuan who was doing a question said.

"Wait, Chenshuang should be back in a few minutes. If she still calls after hanging up this time, I'll answer it." Wang Jiaying replied.

Without any accidents, the phone automatically disconnected again, and then called again, either because there was something urgent, or if the spirit was enough to persevere.

Wang Jiaying stood up from her seat, looked at the caller ID on the phone and let out a soft sigh: "Huh? It says boss? Ask sister Chenshuang to play the piano, the boss? It seems that something is really urgent."

As she said that, Wang Jiaying swooped directly to answer the call, but before she could speak, she heard the other person reporting her family name: "Hi, I'm Ning Wei."

"Ah? Are you Dr. Ning? Dr. Ning from the Mathematics Research Center?" Wang Jiaying asked in surprise.

Hearing this rhetorical question, Xi Yuxuan, who was concentrating on solving the problem, suddenly regained his energy, put down the pen in his hand, turned around, and looked at Wang Jiaying who was answering the phone in surprise.

"I am, may I ask you?"

"You are really Dr. Ning! Oh, I'm sorry, Dr. Ning, I'm Chenshuang's roommate, my name is Wang Jiaying, she went to get hot water, and she will be back in a few minutes, er, but you are not in Montreal to participate Academic conference?" Wang Jiaying said excitedly.

"Oh, yes, I want to discuss some troublesome urgent matters with Chenshuang. When Chenshuang comes back, please ask her to call me, and I will go back." Ning Wei said concisely.

"No problem! I'll notify her as soon as she comes back later."

"Thank you then, goodbye!"

"goodbye!"

……

After hanging up the phone, Wang Jiaying felt like she was dreaming when she put down Jiang Chenshuang's phone, and when she turned her head, she saw the elder sister who was looking at her with piercing eyes.

"Dr. Ningwei's call just now?" Xi Yuxuan asked.

"He said yes! This is not the most important thing, what is important is that you know how Ning Wei called Jiang Chenshuang just now?" Wang Jiaying said mysteriously.

"What's it called?" Xi Yuxuan asked.

"Cough cough..."

Wang Jiaying cleared her throat and imitated Ning Wei's voice and said, "I want to discuss something urgent with Chenshuang. When Chenshuang comes back, please tell her."

When the word Chenshuang was mentioned, the girl imitated it very gently.

"Hey, Jiaying, hearing what you said, I suddenly had a bold idea! Could it be that Dr. Ning actually has that kind of relationship with our Jiaying, right? In the end, there was a scandal for some reason, and I wanted to find our family, Chenshuang. Explain?" Xi Yuxuan asked suddenly.

"Huh? If you think about it in this direction, it is indeed the case. Look, Chen Shuang hasn't played the piano for four days. The day she didn't go out should be the day Dr. Ning left for Montreal, right? And she recently wrote The library has borrowed a lot of mathematics books to read!" Wang Jiaying suddenly realized.

"That's right, I mean, which boss can treat employees so well and buy so many clothes that are obviously not standard for work clothes! If it's true, wow, Chenshuang..."

The two were chatting passionately, Jiang Chenshuang opened the door of the dormitory with a water bottle, and two eyes immediately focused on her.

"Huh? Did something happen?" Jiang Chenshuang asked slightly evasively, being stared at by Shi's piercing eyes, a little unnaturally.

"A major event has happened, Chen Shuang, tell me honestly, what is your relationship with Dr. Ning Wei?" Wang Jiaying asked immediately.

"Ah?" Jiang Chenshuang was a little dazed, not knowing how to answer for a moment.

"Forget about Jiaying, you should call Dr. Ning quickly, he called you three times just now, saying that he has something important to discuss with you." Xi Yuxuan said.

"Oh!" Jiang Chenshuang picked up the phone, unlocked it, and sure enough, there were two missed calls. The top call was connected, and it showed that the call lasted 36 seconds.

This made her a little nervous, and she didn't know what Ning Wei said to her roommate in the dormitory.

When the two roommates looked at her, after thinking about it, they still took their mobile phones and walked to the balcony, hesitating whether to call or not, a call came back.Jiang Chenshuang was startled, then connected the phone: "Hi, it's me."

Then a crisp voice came from the opposite side: "Well, I have two things to ask you. First, those on the Internet are all rumors. There should be someone behind the scenes. I can probably guess the purpose; second, this matter must be resolved as soon as possible. , otherwise it may cause some messy troubles, I decided to announce our relationship to the world, so that all the rumors will be self-defeating, so can we advance our agreement?"

"Of course, don't worry, I won't divulge too much of your private information, and I will do my best to protect your life from any disturbance. Even if I'm not in China right now, academician Tian and Senior Brother Lu will help me Those who take care of you, if you need anything, you can call them directly, or you can send me a WeChat message, anytime, and I will help you find them."

"Is there really going to be trouble?" Jiang Chenshuang asked softly after being silent for a moment.

"Well, to put it simply, my research topic is very meaningful. Some people want me to stay abroad to continue my development, so they always artificially create obstacles, but I still want to return to China. If you don't believe me, you can call Academician Tian now Call and ask." The voice on the other side was still calm.

"Then... alright!" Jiang Chenshuang squeezed the phone nervously, and squeezed out these three words.

"Thank you! So, you agreed to be my girlfriend." The girl who was in a state of tension didn't notice that the voice on the other side was trembling.

"Uh-huh!"

"Then I'll hang up first!"

"Okay, by the way, take care of yourself."

"Got it, sure, I'll be back the day after tomorrow at the latest, what gift do you want?"

"no, I'm fine!"

"Okay, I see. Hang up, goodbye!"

"goodbye!"

……

After hanging up the phone, Jiang Chenshuang put the phone on her chest, closed her eyes, and calmed down her fast beating heart.

Just now, she made the most important decision in her life. She doesn't dare to think about the result now, but she has made up her mind, so no matter good or bad, she feels that she can accept it.

However, when she finally calmed down and walked into the dormitory, she received two extremely gossip eyes again.

Before she opened her mouth, Xi Yuxuan said, "Chen Shuang, we know your temperament, so let's stop talking nonsense. Just ask Dr. Ning whether he will treat us to dinner in a few days according to the previous agreement in the dormitory. Let's eat!"

Jiang Chenshuang hesitated for a while, thinking of the salary he should be able to get immediately, finally nodded bravely.

"Wow...Chen Shuang, you hide really deep, no, I have to call Xiaoyan. Ha, she is not the only woman with a boyfriend in the dormitory now! Also, Dr. Ning said that he and What happened to that princess? Tell us something..."

……

In Montreal, when Yu Xingwei walked into the room with a tangled expression on his breakfast, he saw Ning Wei who was smiling all over his face.

Thinking about what the boss reprimanded him just now, Yu Xingwei didn't understand how Ning Wei could still laugh.

"Mr. Ning, the cold treatment you mentioned last time doesn't seem to be very useful."
