Tech Hammer

"Tell me, there was a rumor last night that an oriental boy who didn't understand the charm appeared at this meeting. Could it be that he was talking about you?"

The next morning, when Feng Shaojie saw Ning Wei, there was a smile on his face.

"Then it must be him!" Yu Xingwei added next to him.

Yesterday, he made fun of Ning Wei a lot about this matter.

"Haha, Ning Wei, you're done. Lucy is the bright spot in the eyes of many young people attending this meeting. You can actually let her fall. Believe me, you will become a thorn in the eyes of countless people."

"Is she famous?" Ning Wei asked with a frown.

Inexplicably, Ning Wei thought of what the girl said in the restaurant yesterday before turning around and leaving: "My name is Lucy Ron, and I will definitely let you remember this name."

"No, as a person doing algorithm research, haven't you heard of Lucy Rowan? A genius girl from Harvard. How many 23-year-old female Ph.D.s from Harvard have you seen? Mention her improved quantum genetic algorithm neural network integration technology directly Being adopted by Google, it is said that it can improve the generalization ability of neural network integration. Of course, I don’t do research on this area, and I don’t know the specific situation. But she is Harvard’s darling, do you understand?” Feng Shaojie introduced.

"Well...actually my main job is not algorithm research. I am currently studying mathematics, more specifically the Mathematics and Applied Mathematics major of Jiangsu University." Ning Wei said annoyed.

"Uh..." Feng Shaojie, who was waiting for the elevator with the two of them, was stunned and subconsciously looked at Yu Xingwei aside.

"Didn't Professor Shen tell you about our Mr. Xiao Ning's major?"

Feng Shaojie was stunned for a moment, then looked at Ning Wei: "Okay... I never said this. Sure enough, mathematics determines the upper limit of an algorithm engineer!"

…

Feng Shaojie took the three of them to the exhibition hall of the conference first, and Ning Wei finally saw the poster exchange mentioned in the conference manual.

It was not as formal as he imagined. A small table, a notebook, a few drawing boards used to separate a space and academic posters posted on them completed a simple communication place.

If the conditions are good, a small projector and screen will be provided. More people will display the monitor directly outside. When someone stops to look at the poster, they will start to explain their thoughts and ideas simultaneously.

"I still have something to do, so I won't accompany you. If you are interested, you can take a stroll here first. The first report will start on time at nine o'clock in the No. 1 Conference Hall."

"Okay, go and do your work, Brother Feng."

…

"The first report will be about quantum particle swarm algorithm, which has nothing to do with our research. Why don't we visit the poster booth in the hall first?" Ning Wei suggested.

"I think we should go to the report meeting first. After all, this is your first time to speak at such a report meeting. It would be better to learn from the experience first and then experience the questioning style of the big guys in the audience." Yu Xingwei He shook his head. For him, Ning Wei's performance in the afternoon was the most important.

"Just go to the second show at 10 o'clock. Look, there are many very new things in the poster area. Look, there is also a demonstration of a set algorithm that can efficiently solve the three-dimensional binning problem." Ning Wei pointed to the distance opposite. The two said from a stall about three meters away.

"That's...ok!" Yu Xingwei finally nodded.

In fact, compared to the serious report meeting, the atmosphere in the poster hall was obviously much more relaxed and more lively, and arguments could be heard from time to time.

However, when the two of them walked over and took a look, they were both stunned... They were still acquaintances.

"It's you?"

"Is it you?"

In fact, I’m not too familiar with him, I just met him when I was applying for a visa.

"Um, didn't your paper pass review and the conference invited you to give a report? Why did you put up a poster?"

"Ahem..." The man coughed awkwardly twice before saying, "We are all brothers from China. Please don't cause trouble."

As he was talking, someone stopped in front of the poster booth, and the man hurriedly greeted him.

"Sir, if you are interested in the optimal three-dimensional binning problem, you must not miss this product."

"Okay, tell me."

The man glanced at Ning Wei and Yu Xingwei. Seeing that they had no expression, he breathed a sigh of relief, then opened the computer in front of him and began to explain.

"You see, this is a three-dimensional boxing software I designed to perfectly solve the three-dimensional boxing problem and solve the problem of logistics waste for enterprises. The whole system consists of several aspects. First, it uses heuristic algorithms to carry out spatial analysis. Segmentation, spatial merging and simple block generation. In this step, the system will automatically generate a Cartesian spatial coordinate system based on the data input by the enterprise..."

"I'll go, what is this?"

Watching the man's display and introduction, Ning Wei quietly asked Yu Xingwei beside him.

"It seems that the heuristic algorithm, tabu search algorithm, ant colony algorithm, and simulated annealing algorithm are all integrated into one software?" Yu Xingwei said uncertainly.

“So where’s the innovation?”

Yu Xingwei glanced at Ning Wei with a complicated and unspeakable look, and said, "Mr. Xiao Ning, don't you think that everyone who makes technology in the world is a genius? Can you integrate existing things and make them play a greater role?" The efficiency is already a rare talent, and it can be regarded as an innovation. As for directly creating a field that has not been touched by predecessors, and directly solving problems that predecessors cannot solve, how many people in this world do you think can do it? Arrive? At best, this is false propaganda, but this is not China, so who cares?"

This makes sense. Ning Wei nodded and said, "Brother Yu, don't always praise me in such a different way. You're embarrassed."

Yu Xingwei: "..."

While the two were talking, the foreigner who listened to the man's introduction finally shook his head and left without leaving the man's contact information or information.

Ning Wei and Yu Xingwei also planned to leave. After listening to the introduction, they already felt boring. A slim figure suddenly appeared in front of Ning Wei.

Ning Wei raised his head and glanced, and then he recognized that it was the female top student who fell behind his support yesterday. People are like this, changing a set of clothes can give them a different temperament.

Wearing a smart and decent little suit and a pair of gold-rimmed glasses, she immediately looked like a female doctor. With her stern face, she looked like a goddess. But Ningwei only felt a headache. What was even worse was that When he saw the beauty walking towards the two of them, Yu Xingwei took a step back unfaithfully.

"Miss Ron..."

"Don't call me by my last name, just call me by my first name. My name is Lucy!"

"Well, Lucy, I really didn't mean to do it yesterday."

"It doesn't matter, I already know that your name is Ning Wei. There will be your report meeting this afternoon. Last night I almost stayed up all night to re-study your paper and prepared more questions. So, Ning Wei, please Get ready to take the fight."

After speaking, Lucy glanced at Yu Xingwei, turned around and left gracefully.

Now Ning Wei had no intention of continuing to wander around the poster area. He turned to the unloyal Yu Xingwei and said, "Brother Yu, let's go, let's go to the report meeting."

"Wait a minute, Ning Wei, I heard that when a man changes his mind because of a woman, he likes her. Are you in love with that Lucy?" Yu Xingwei asked worriedly.

After this trip, if Ning Wei had a girlfriend in the United States, he felt that his end might be miserable after returning to China...

Hearing this, Ning Wei was shocked and looked at Yu Xingwei in surprise: "Brother Yu, where did you hear this argument?"

"Online, I think it makes sense."

"On the Internet, it is also said that women have big breasts and no brains. Do you think it is appropriate to apply it to the woman just now?"

Yu Xingwei shook his head without hesitation.

"Isn't it? Brother Yu, you actually observed it?"

"I……"

"Okay, Brother Yu, let us listen to the conference report carefully."

…

When Ning Wei and Yu Xingwei approached Lecture Hall No. 1, the large conference room, which could accommodate at least nearly a thousand people, was almost full.

Of course this is understandable.

Generally speaking, the higher the ranking of reports from such top academic conferences, the more attention the report content receives.

As an opening academic report, it will naturally attract more people to come to observe and learn.

What surprised Ning Wei was that the staff standing at the door of the lecture hall did not check the representative certificate issued by the organizing committee.

Later, he learned that if there were extra vacancies in this kind of meeting, the entry and exit of people would not be restricted. Of course, if you want to get a front-row seat where you can ask questions, the representative certificate exchanged for the invitation letter will come in handy.

Although I initially felt that I was not too interested in the first report on particle swarm optimization based on quantum behavior at the conference, I really listened to it and found it quite interesting, but that was all.

Simply put, this is an algorithm developed from the swarm intelligence algorithm.

A typical representative of swarm intelligence algorithms is the particle swarm optimization algorithm, which simulates the behavior of bird groups, referred to as the PSO algorithm. Since this algorithm was proposed in 1995, it has attracted the attention and research of many scholars in related fields at home and abroad due to its simple calculation, easy implementation, and few control parameters.

But the algorithm’s features are as outstanding as its advantages.

First of all, theoretically speaking, it is not a globally convergent algorithm; secondly, the speed and position evolution formula of the algorithm makes the randomness and intelligence of the particle swarm low; in addition, the dependence of the algorithm performance on the upper speed limit reduces its robustness.

By thinking about this algorithm and introducing the concept of particle swarm optimization, people advanced this algorithm.

Its application fields are mainly in multi-peak and multi-extreme function optimization problems, complex engineering optimization problems, such as stochastic planning, system identification, etc...

But after a ten-minute break, when the second report meeting officially began to introduce a new random algorithm, Ning Wei discovered something different.

This is no longer a question of whether it is interesting or not, but as the reporter on the stage continued to explain in depth, his brain reacted again and listed many problems that the algorithm urgently needs or should solve.

This is very interesting.

You must know that the first lecture will be a 60-minute lecture, but the organizing committee of today’s second lecture only gave Professor Lermontov 45 minutes on the stage. Don’t underestimate these fifteen minutes. This is a big deal. It represents the difference in the importance that the top group of people in the field of computer algorithms place on the two.

However, Ningwei only found it interesting when listening to a report, and nothing else.

Listening to the second report meeting, many associations were automatically generated and many ideas popped up.

So this means that this new random algorithm is more valuable to his current research, or that the innovation of random algorithms has a greater role in advancing the field of artificial intelligence?

Ning Wei didn't think about this question for the time being, but he listened more seriously, and then silently remembered the professor's name in his heart, preparing to read the professor's papers carefully when he went back.

…

The three morning report sessions ended with Ningwei immersed in thinking about algorithms.

Compared with this kind of top-level meeting, the report meeting on the first day is actually a bit intensive. In the 180 minutes from 9 to 12 o'clock, there are 150 minutes of high-quality report meetings. It's actually not very friendly to real listeners.

There are so many unrelated but informative things to digest, which is not an easy task.

Ning Wei only felt that he had gained a lot. Until the end of the last press conference, his mind was still filled with various ideas for improving random algorithms. He even felt that he could vaguely feel the pulse of the development direction of the artificial intelligence field, but he still couldn't. Thinking too clearly. It was like a graceful beauty hiding behind a hazy veil, but he was still unable to lift the veil and get a glimpse of the whole thing.

This feeling was so disturbing that he almost forgot that two hours later, he would be sitting on the podium to report to thousands of industry elites. As for the Harvard beauty genius who wanted to find trouble, he had already forgotten it.

Until the end of the last report meeting, he was still staring at the big screen that showed the PPT in a daze.

Until Yu Xingwei patted him heavily on the shoulder: "I said Ningwei, what are you thinking about? I didn't hear you twice? I went to eat. Aren't you hungry? I have already digested the two pieces of bread in the morning. It’s over!”

"Oh!" Ning Wei stood up regretfully and suddenly asked: "Senior Brother Yu, have you thought about the direction of your PhD topic?"

"Huh?" Yu Xingwei was stunned, and said in astonishment: "Please, I was caught by you in the project team as soon as I got my Ph. .”

"How about choosing a random algorithm? I have a feeling that this direction will definitely be very useful in the future." Ning Wei said with certainty.

"Huh?" Yu Xingwei was stunned.

Ning Wei successfully turned his little trouble into Yu Xingwei's little tangle.

For a Ph.D., topic selection is a very sacred matter. It is related to whether he can graduate, and it is also related to his employment prospects after graduation.

So, when Ning Wei had gathered his emotions and sat on the rostrum of the conference, ready to start his report, Yu Xingwei sat in the audience and was confused, what did Ning Wei mean? Why did he suddenly recommend him to choose the direction of random algorithms?

"As we all know, the framework of fluid mechanics contains eight major sub-disciplines, including turbulence and transition, artificial intelligence and machine learning. The turbulence algorithm combines the application of N-S equation solutions in a special situation. We all know The Navier Stokes equation in physical space is essentially the most concise and efficient expression of a flow field, and the first step of the turbulence algorithm is to transform a network space where data lives into an intuitive physical space..."
