Tech Hammer

This time it took three hours less time to fly to Montreal than to Washington. However, this time Ningwei specifically chose the Boeing 777-300ER extended-range wide-body aircraft with a first-class cabin. The advantage is that it is equipped with 180-degree fully flat adjustable seats and a central bar. It is also equipped with personal entertainment and power supplies. System, and what needs to be praised is that the scene lighting on the plane can also simulate the wonderful moments from sunrise to sunset.

In fact, he doesn't know much about these things, but fortunately there are people who can help him understand them. After the last 40 million reward was credited to his card at once, the bank's account manager called him and added him on WeChat. From time to time, he would send some financial management text messages.

Of course, Ningwei ignored these, but when I was booking air tickets, I thought of some of the service scope promised by the bank, so I tried to ask, and then booked these two air tickets through the bank.

This also made Ning Wei understand that the original flight missions were of different models, and the first class and business class were actually two different concepts. It's pretty good. If you don't take into account the extra expenses, this journey is at least much more comfortable. At least you can lay down the seat flat and sleep quietly on it, and the flight attendant thoughtfully sent you a blanket. Sure enough, rich people never wrong themselves.

However, apart from allowing himself to sleep more comfortably, Ning Wei did not enjoy any other services. After getting on the plane, he put on his headphones and started the single loop mode of "Under the Fuji Mountain", but the one he played was not the original version, but the one he had just discovered. A version co-operated by Zhou Shen and Li Hackin.

There was no other reason, but he simply thought that the two people's interpretation of each other's harmonies made him feel that it was particularly suitable for his mood at this time, and he thoroughly expressed the second degree of a young man who acted entirely based on his feelings.

After getting off the plane and waiting to go through customs, Ning Weicai was reluctant to take off his headphones and said to Yu Xingwei with infinite sigh: "Brother Yu, I must take Jiang Chenshuang to Mount Fuji in the future."

When Yu Xingwei heard the music leaking from his headphones, he glanced at Ning Wei with a complicated look and asked, "Mr. Xiao Ning, actually you don't understand Cantonese very well, right?"

Ning Wei shook his head. Although he wasn't very good at speaking, he remembered the lyrics after reading them once. How could he not understand them?

"Then don't you feel that this is a song about broken love? The situation between you and Jiang is not at this stage yet?" Yu Xingwei asked cautiously.

Yesterday, he suggested Ning Wei to say goodbye to classmate Jiang, but the two of them didn't know what they said. Ning Wei turned around and went home directly without waiting for him. After returning home, he went to tinker with March. Of course, Even if he didn't mess with March, it would be hard for him to ask.

Before getting on the plane, he had been tinkering with his mobile phone. He wore headphones the whole time on the plane, but he was listening to such a song, which made him feel at a loss.

"Don't panic, I haven't had time to fall in love yet. Listen to it more while you're not in love yet, and stop listening to it after you fall in love, so as not to be unlucky." Ning Wei nodded, and then put on the headphones again.

Well, that makes sense.

He felt very uneasy, but in fact, Yu Xingwei felt that Ning Weicai looked more like a normal young man when he listened to the music, unlike when he was studying, which sometimes made him feel that Ningwei was focused like a robot.

…

When he came to Montreal this time, Ning Wei declined Director Tian’s suggestion to find a local friend to pick him up to the venue of the conference. As a man in his twenties, he couldn’t rely on someone to take care of him every time he went out. However, when the two of them completed the customs clearance procedures and came to the airport exit, they immediately saw an acquaintance waving at them.

That's right, it was Feng Shaojie who picked them up at the last SODA conference in the United States and sent them to a local shopping mall to buy laptops.

The two of them immediately walked over, and Ning Wei took off the headphones when he got close, and asked in surprise: "Huh? Brother Feng? Are you and Professor Shen also here to attend this conference? Also, how do you know about our flight?" of?"

Feng Shaojie glanced at Ning Wei with a complicated and unspeakable look, and replied: "Forget it, the teacher and I didn't plan to attend this conference. It wasn't because of your paper that the teacher decided to bring me here at the last minute. Oh, By the way, you also asked me to study hard with you. As for knowing which flight you are taking, wouldn’t it be easier? Isn’t it OK for my boss to call Brother Yu’s boss?”

"Oh!" Ning Wei nodded, not feeling too strange.

Feng Shaojie continued to smile and said: "Also, as far as I know, there are at least 200 people brought by the mentor to listen to your report this time. They also created a group on Twitter. I said in the group that the boss wants to I came to pick you up. Everyone asked me to be more enthusiastic and enthusiastic so that you can fully experience how much everyone is looking forward to your arrival. Some people also suggested that I take you directly to the underground parking lot of the hotel. They can Let’s prepare a surprise party for you.”

"Oh! Are there any beauties at the surprise party?" Ning Wei asked.

"Yes! Absolutely! Are you going?" Feng Shaojie raised his eyebrows and asked.

Ning Wei glanced at Yu Xingwei and replied arrogantly: "I already have a wife, so I won't go. Brother Yu is still single. He admired the party culture here last time. Why don't I come here later?" Get off the bus in front of the hotel and go back to your room to rest. You can take Brother Yu to have some fun. He is also one of the authors of the paper and deserves a warm welcome ceremony."

Yu Xingwei shook his head with an upright look and said, "No, I don't. I don't deserve it, and I won't go! I just want to sleep now."

"Okay, let's go! There's no surprise party, I'm kidding you. I'd rather you have a party for the elderly to attend. The boss and many people are thinking about talking to you about something serious." Feng Shaojie shook his hand and took the money from the hotel Rented car keys, said.

…

The second time I went abroad, my mentality was different. For example, Ning Wei was less excited about the scenery outside the window, so he put on his headphones again after getting in the car.

Feng Shaojie also became much quieter, not as talkative as the first time.

To be honest, when he first met Ning Wei and Yu Xingwei, Feng Shaojie thought that these two guys were just country bumpkins who had never seen much of the world, so he was trying to show off when he expressed his opinions.

But this time it’s different, I can’t think of anything to show off.

Show off your knowledge? God knows whether they have never seen it or are simply not interested in learning about it, showing off their knowledge? Don't be kidding, let's not talk about the NS equations. The 206-page paper alone has been a nightmare for countless people in the past two months.

After carefully studying the paper, I realized that everyone's academic level is not at the same level at all. Those dazzling space transformation techniques and strings of self-derived lemmas are simply a large-scale magic show.

Especially when Lemma XX, Lemma XX, and the above discussion appear in the paper, it can be easily concluded...

This is the biggest nightmare. Rather than formulas and conclusions that can be easily listed in papers, they often need to go to the professor and then throw out a bunch of theorems and various transformations to demonstrate. The entire argumentation process can often be Write a big blackboard, and then come to the conclusion, well, the explanation of the paper is correct, but it requires a few changes. Don't you understand?

Well, I have to say that this process has helped everyone review many basic mathematical knowledge, such as Z transform, Laplace transform, Fourier transform, Praps transform, differential state equation of continuous time system, discrete time System differential state equations, as well as higher-end multi-dimensional space transformations and functionals... etc., etc.

What is shocking is that these basic knowledge can still be used in this way?

What's more annoying than having your IQ suppressed? Probably because his IQ has been continuously suppressed!

This is also the original intention of establishing the group mentioned by Feng Shaojie.

After all, these are a group of extremely proud young people. It would obviously be intolerable to constantly ask professors for advice if they encounter such problems, so everyone can discuss the things they don't understand privately.

At least someone has asked question A to their instructor, so others don't have to go to their professors to ask it again. When encountering questions that haven't been asked yet, everyone can brainstorm and find a way to understand it most of the time.

It's just that a month of playing like this is really too short, and it's not enough for them to understand all of this paper. Some people even still can't understand it thoroughly even after being explained.

So the content of the chat within this group is very clear. Before discussing the problem, greet Ningwei cordially. After the problem is discussed, greet Ningwei cordially again...

In this way, in the younger generation of algorithmic academic circles, everyone brainstormed and gave Ning Wei an unkind but absolutely appropriate English name based on Western naming habits, "Ning. Notorious. Not good at martial arts. Author." Deadly stunts · Founder of shit theory · Summer vacation terminator · Mathematics pervert · Studying and being a human being · More annoying than my husky · Public enemy · Derivation nightmare · Not worthy of a girlfriend · Paper madman · Killing with a pen instead of a knife · Give me back the party ·I am an undergraduate student·for”!

Well, the group even agreed that if the name Ning Wei appears in the group chat, it would be disrespectful to Mr. Ning Wei if he did not use the full name above.

For one of the first people to join the group chat, Feng Shaojie looked at Ning Wei. What else could he say? Yes, before he could achieve such a great reputation in the world, he really didn't have much interest in saying anything to Ning Wei.

Maybe when he was expressing his inner feelings, people were thinking, look at this idiot, pretending to be well-informed, but actually he doesn’t understand anything...

Yes, no one wants to humiliate themselves.

…

Just like that, we arrived at the hotel without saying anything.

The arrangements made by the organizing committee are very considerate. The hotel and the conference center are integrated, and you can directly reach the place where the conference will be held the next day from the corridor.

It was probably the afternoon of the day before the meeting. When Ning Wei walked into the hotel, he saw that the lobby had begun to become lively. People could be seen gathering in twos and threes everywhere and chatting about something. The places for guests to rest at the entrance of the hotel had been occupied. It was full.

"Look who is here? Oh, Ning Wei, our friend, we meet again."

Before Ning Wei could reach the bar, a warm greeting attracted the attention of many people in the hall, and everyone's eyes were focused on the young man who had just walked into the hotel.

Ning Wei was startled, took off his earphones, and looked towards the direction where the sound came from.

John Wilson, who was not an old friend but had met once before, had stood up from the sofa in the hall where guests could rest and looked at him with a smile. Not only Professor Wilson, but also Professor Shen and several others An old gentleman he had never met before.

Hey, that stupid woman from Harvard is here too?

"Professor Wilson, Professor Shen, hello." Ning Wei came over and said hello.

"Young man, are you tired? If not, come and have a casual chat with us old guys. Oh, no, there is also our young and beautiful Princess Isabel and our future youngest beautiful professor at Harvard, Miss Ron." John Wilson said enthusiastically.

Only then did Ning Wei notice that there was a young white girl sitting next to Lucy Ron, looking at him curiously.

"I'm not tired, but I have to check in first, right?" Ning Wei replied.

"It's not troublesome, Shaojie. Go and help Dr. Yu and Ning Wei check in. Let Dr. Yu go and have a good rest first. You can bring a room card to Ning Wei later." Professor Shen explained at the side.

"Okay, Professor Shen." Feng Shaojie replied honestly.

Well, I can't refuse now.

In fact, Ning Weidao didn't mind communicating with these big guys, but the woman next to him kept glaring at him with a murderous look, which made people uncomfortable.

As for the girl next to Lucy, Ning Wei remembered that John Wilson used the word princess when he introduced her, but he didn't take it too seriously.

"Come on, let's sit and chat. Let me introduce you formally. This is Mr. Wall. I believe you must have heard of him. He designed the Perl language."

"Hello, Mr. Wall, I've seen you for a long time." Ning Wei nodded to the old boss.

"Well, your turbulence algorithm amazed me." Larry Wall nodded slightly and replied.

"This is Michael I Jordan, who is recognized as the father of machine learning and one of the important guests of this conference." John Wilson continued.

"Oh, hello, Professor Jordan. The probability graphical model you designed has inspired me a lot." Ning Wei said.

This sentence is not a compliment at all. Many people may have never heard of this scholar in front of me, but each of his students is already a big boss in the industry.

For example, the famous artificial intelligence deep learning experts Wu Da and Xing Jiaxiang are his students. Ian Goodfellow, who once proposed the adversarial generative network, is a student of his students. He himself is indeed worthy of being said as the father of machine learning. .

"Haha, similarly, your paper makes me feel like I'm back to my youth." Professor Jordan nodded and smiled.

"Oh, how could I forget our Princess Isabel? Well, I have to admit that we just happened to meet. She became very good friends with Lucy when she was an art major at Harvard. This time she was invited to attend the Montreal At an event at the Museum of Fine Arts, two people got together. You are both young people. Maybe after chatting with us old men, you can go have a drink and then have a good rest." John Wilson said with a smile.
