Tech Hammer

For Ning Wei, he didn't think the scandal was very confusing. On the contrary, research in number theory is what troubles him the most.

The reason why he has always believed that he has only made staged progress is because compared to 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 mathematical definition of data, and giving it mathematical expression, such as its number field type numbers and its physical dimensions. At the same time, the abstract expression of data and its relationship model also need to be reconstructed.

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 entire theory, this superstructure needs to be strictly defined so that the entire big data system can be described in mathematical language.

The difficulty involved is conceivable.

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

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

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

If you put it into the machine's perspective, Ning Wei summarized the structure of data defined through categories and sources.

Observation 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 existence 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.

Analogy includes similarity, comparison, and equivalence classes; relationships include association, causation, mapping, sequence, and concurrency;

Measurement includes quantification, qualification, scaling, standardization, weighting, and classification;

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

Mathematics includes linear, nonlinear, polynomial, analytic, differential, integral, refinement, and function systems;

Statistics includes probability, norm, deviation, distribution, conditions, and random processes;

Composite includes interpolation, extrapolation, exponential, power function, factorial, Cartesian product, search, sorting, combination, permutation, and system fusion.

In addition, there are engineering data, social data, etc...

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

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

Until a call came directly from China.

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

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

"The domestic self-media has almost gone crazy. The past two days have been full of news about your relationship with the Swedish princess. As a result, I, an old guy, have just received several calls asking about you, and your former Jiang Da Professor’s phone number.” Tian Yanzhen said angrily.

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

This is what Ningwei cannot tolerate.

"Director Tian, ​​I have no relationship with that Isabel. I will explain it to you when I get back. I still have some important things here."

"It doesn't matter. I don't have to interfere with your personal affairs, but some issues are more complicated after all, so you have to think about it. If you have something to do, just go ahead and get busy. I won't disturb you anymore."

After hanging up the phone, Ning Wei shut down the data architecture construction he was doing and started logging on to the domestic website to find out what happened in just two days.

Sure enough, the Internet was full of pictures he had searched on Google and various short stories written based on the pictures.

What puzzled him the most was that a group of booing people kept praising him for bringing glory to the country. The bottom line of glory was too low. After chatting with a woman for a few words and taking a photo with him by the way, was he a glory?

Ning Wei was almost angry.

Then he probably understood why the news was getting hotter.

The answers of several professors who participated in this conference sounded wrong, and the ambiguity could rush out through the screen.

Well, the messy news on the Internet made Ning Wei feel depressed, so he closed the web page and began to think quietly about how to deal with the whole thing. He could probably analyze Classmate Jiang's mentality. She probably understood what the girl would think after seeing this news, so she could empathize with it from the perspective of mindset, reverse the roles, and then bring in...

The brain was running rapidly, and curves were generated in the brain and then disappeared. Especially during the short exchange with Jiang Chenshuang, every reaction of the girl became the basis for judging the result.

Ning Wei soon made up his mind and took a look at the computer. It was already half past eight in the morning. China time and Montreal time are exactly twelve hours apart, which means it is 20:30 Beijing time.

Ning Wei picked up the phone without hesitation and called.

The call went through, but no one answered. It automatically hung up after forty seconds. Ning Wei called again without hesitation, three times in a row...

When the call was connected, Ning Wei said without hesitation: "Hello, I'm Ning Wei."

"Ah? Are you Dr. Ning Wei?"

…

The time rewinds back to a few minutes ago, and the location is thousands of miles away, focusing on the No. 202 girls dormitory in Building 33 where the finance major of Kyungseong University is located.

Several girls were busy chatting casually while doing their own things.

"Sister Yuxuan, are the scandals about Dr. Ning on the Internet true? The PhD student from Yanbei University is in Montreal. It's quite scary to see our school name appearing in such a title." The most popular person in the dormitory The lively and youngest Wang Jiaying looked at her phone and chatted casually with the girl at the table next to her.

"Who knows? But what I read on the Internet is a bit confusing. But looking at the photos, the two people may have some kind of relationship." Xi Yuxuan, who was asked, also responded casually.

"Hey, our senior Ning's treatment is comparable to that of those big stars. Hey, by the way, Chen Shuang, why haven't you done your part-time job playing the piano in the past two days?" Wang Jiaying turned her head again and looked at the book she was reading. Jiang Chenshuang asked.

All the girls in the dormitory knew about Jiang Chenshuang's part-time job as a piano player, otherwise they wouldn't be able to explain the appearance of several new clothes. Of course, I don't know anything else.

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

"Oh, my boss gave me a day off these days." Jiang Chenshuang turned around and smiled, and replied softly.

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

This moment made her feel a little sad and lost, but after this little emotion, she felt a little inexplicably relaxed. 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 just because she felt from Ning Wei that in addition to being domineering when he sent her back to the dormitory that night, he also had the feeling that he had not disturbed her for more than a month. Her respect was a heart-warming feeling, so she wanted 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 haven't started at all, not to mention that she feels that Ning Wei really deserves someone better.

It’s actually 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 will fetch water for you?" Jiang Chenshuang asked.

The dormitory building of Yanbei University has several drinking fountains that provide boiled water 24 hours a day. This is probably one of the benefits of the dormitory.

"No, I still have half a bottle."

"I don't need it either!"

"Well, I'll go first."

After saying that, Jiang Chenshuang left the dormitory with the water bottle and placed her old-fashioned Samsung mobile phone on the table.

As a result, not long after I left the house, my cell 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 answer the call and ask if there's anything urgent? If you're in a hurry, you can send the phone to Chen Shuang." Xi Yuxuan, who was working on the question, said.

"Wait a minute, Chen Shuang should be back in a few minutes. If you still call after hanging up this time, I will answer the call and ask." Wang Jiaying replied.

Without any surprise, the call automatically disconnected again, and then called again. Either there was something urgent, or I was energetic enough to persevere.

Wang Jiaying stood up from her seat, looked at the caller ID on her mobile phone and let out a sigh: "Huh? It says boss? Is that the boss who asked Sister Chenshuang to play the piano? It seems like there is something urgent."

As she said this, Wang Jiaying dialed the phone directly to answer the call. However, before she could speak, she heard the person on the other side announcing her home: "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 immersed in the problem, suddenly became energetic. He put down the pen in his hand, turned around, and looked at Wang Jiaying who was answering the phone curiously.

"I am, are you?"

"You are really Dr. Ning! Oh, I'm sorry, Dr. Ning. I am Chenshuang's roommate. My name is Wang Jiaying. She went to get hot water and will be back in a few minutes. Well, aren't you in Montreal? An academic conference?" Wang Jiaying said excitedly.

"Oh, yes, I have encountered some troublesome urgent matters and I want to discuss it with Chen Shuang. When Chen Shuang comes back later, please ask her to give me a shot and I will go back." Ning Weiyan said concisely.

"No problem! I'll let her know when she comes back later."

"Thank you then, bye!"

"goodbye!"

…

After hanging up the phone, Wang Jiaying felt like she was in a dream when she put down Jiang Chenshuang's phone. When she turned around, she saw her eldest sister looking at her with bright eyes.

"Dr. Ning Wei's phone call just now?" Xi Yuxuan asked.

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

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

"Ahem..."

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

When the word "morning frost" was mentioned, the girl imitated it very gently.

"Hey, Jiaying, after hearing what you said, I suddenly had a bold idea! Could it be that Dr. Ning is actually related to our Chenshuang? I don't know why there was a scandal, and we wanted to find our Chenshuang Explanation?" Xi Yuxuan suddenly asked.

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

"Yes, I mean which boss can treat his employees so well and buy so many clothes that are obviously not standard clothes to make work clothes! If it is true, wow, then Chenshuang..."

The two were having a heated chat when Jiang Chenshuang opened the bedroom door with a water bottle, and his eyes immediately focused on her.

"Huh? Did something happen?" Jiang Chenshuang asked slightly dodging as she was stared at by Youyou's bright eyes.

"Something big 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 dumbfounded and didn't know how to answer for a while.

"Ignore Jiaying, please call Dr. Ning immediately. He just called you three times and said he had something important to discuss with you," Xi Yuxuan said.

"Oh!" Jiang Chenshuang picked up the phone and unlocked it. Sure enough, it showed two missed calls. The top call was connected and the call duration was 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' eyes fell on her, they thought for a while and walked to the balcony with their mobile phones. Hesitating whether to call her, another call came. Jiang Chenshuang was stunned for a moment, then answered the phone: "Hello, it's me."

Then a crisp voice came from the opposite side: "Well, I have two things to do with you. First, those on the Internet are all rumors, and 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 might cause some messy trouble, I decided to announce our relationship to the whole world, so that all the rumors can be dispelled, so can we advance our agreement?"

"Of course, don't worry, I won't reveal too much of your private information, and will do my best to protect your life from any interference. Even if I'm not in the country now, Academician Tian and Senior Brother Lu will help me if I need anything. To 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."

"Will there really be trouble?" Jiang Chenshuang was silent for a moment and asked softly.

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

"Then...okay!" Jiang Chenshuang squeezed the phone nervously and squeezed out these three words from her mouth.

"Thank you! So, you agreed to be my girlfriend." The girl who was in a nervous state did not notice that the voice on the other side was also trembling.

"Uh-huh!"

"Then I'll hang up first!"

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

"Yes, I'm sure. I'll be back the day after tomorrow at the latest. What gift do you want?"

"no, I'm fine!"

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

"goodbye!"

…

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

Just now, she made the most important decision in her life. She didn't dare to think about the outcome now, but she had already made up her mind, so no matter good or bad, she felt that she could accept it.

However, when she finally calmed down and walked into the bedroom, she was once again greeted by two extremely gossipy looks.

Before she opened her mouth, Xi Yuxuan said: "Chen Shuang, we know your temperament, let's not talk nonsense. Just tell us directly that according to the agreement in the dormitory, will Dr. Ning treat us to a meal in a few days? Let’s eat!”

Jiang Chenshuang hesitated for a moment, thinking about the salary he should be able to get soon, and finally nodded bravely.

"Wow... Chenshuang, you're really hiding it. If you can't, I'm going to call Xiaoyan. Ha, she's not the only woman in the dormitory with a boyfriend now! Also, Dr. Ning said he and What happened to that princess? Tell us some news..."

…

In Montreal, when Yu Xingwei walked into the room carrying breakfast with a troubled expression, he saw Ning Wei with a smile on his face.

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

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

"Well, it's really useless." Ning Wei nodded.

"Then what are you going to do?" Yu Xingwei asked.

"Wouldn't it be better to tell the whole world that I'm in love and let the whole world bless us?" Ning Wei said matter-of-factly.

"Isn't it right? Mr. Xiao Ning, are you planning to have an exotic love affair with that Princess Isabel?" Yu Xingwei said in shock.

"What the hell..."

Before I could say anything more, the phone rang again, it was Lao Ning calling...

Ning Wei glared at Yu Xingwei and answered the phone: "Hey, dad, the Internet is full of fake news. I already have a girlfriend, who is also a student of Yan University, and I am planning to clarify it. Otherwise, don't say you can't forgive me. I, your future daughter-in-law, can’t forgive me. Well, I won’t tell you more, international long distance is quite expensive!”

After hanging up the phone, looking at Yu Xingwei who was stunned, Ning Wei asked: "Okay, you heard it, classmate Jiang agreed to be his girlfriend! What gift do you think I should bring her back? Forget it, I almost forgot, Brother Yu, you are still single, what should I say, Brother Yu, you want to have a girlfriend, you can’t be too straight!”

Yu Xingwei: "???"
