Chinese entertainment for engineering students

"I heard that Wang Xu ran away again? Why didn't you let Xiao Liu clean it?" Professor Luo Congwen came to Wang Xu's office carrying a big teapot, and saw Director Jiang cleaning the table.

Xiao Liu is Wang Xu's new secretary here. He was introduced by Director Jiang. He graduated from National Defense University and now works in the laboratory. His job title is laboratory technician, but he is actually a secretary.

This child had served as a soldier and received military training. He was recommended to the university only for his outstanding performance. He had a clean family background and was very quick at work. He was deeply trusted by Wang Xu.

Not long after arriving, he had already secured his position as the first brother in the office. Well, there were only him and Wang Xu in the office. If Wang Xu wasn't around, he would be the first brother, so there was nothing wrong with him.

"Well, I went to the northwest. I said I was going to overlook the scenery, but in fact I just went to have fun. There was no one with a view and his wife, so I asked Xiao Liu to go with me. I wanted to be a lightbulb that wouldn't kill him.

He brought the drone team there as well, as if he was going to experiment there. He could just do it, it wasn't like the Imperial Capital couldn't experiment. "Director Jiang felt a little headache and complained about Wang Xu's activities.

“Drone team, have they figured out their algorithm?

This is what I asked him about. He told me that he wanted to use artificial intelligence to train flight control, which is different from traditional algorithms. I just sorted out some clues. Where did he get the algorithm? "Professor Luo looked confused. Indeed, Wang Xu recently gave Professor Luo a job, which was to study flight control.

“What the Imperial Aviation Institute does should still be fly-by-wire flight control in the traditional sense.

He said that traditional ones also have traditional benefits. They require low computing power, can easily control costs, can be easily modified when encountering problems, and can quickly form products. Walking on both legs must be carried out without lameness. "Professor Luo glanced at the notebook. Wang Xu had explained this matter and he had a record.

"Well, it's true. The large-scale model algorithm requires too much computing power, and it can't even be used on local workstations. At least it needs a cabinet machine to use it.

It is estimated that for at least ten years, it will not be possible to make a chip and carry it to the sky. "Professor Luo nodded. The most complicated thing about neurons is calculation. The more parameters there are, the more complicated the calculation is, and the greater the computing power required. A four-axis flight control does not require too many parameters.

But if it involves automatic obstacle avoidance, dynamic route planning, or even the operation of drone swarms, the computing power requirements will increase exponentially.

Even the training is performed on a supercomputer, and the manipulation itself is just the result of the calculation. However, huge model networks also require complex operations to obtain results, which is the shortcoming of artificial intelligence algorithms.

If the traditional flight control algorithm is used, the flight effect is not much different, but the cost can be greatly reduced. However, it is somewhat inadequate for various terrain matching, obstacle recognition, and flight route planning.

This is also one of the important reasons why Wang Xu has begun to lay out artificial intelligence algorithms now. It is hard to say whether you can train this thing, but you must have it in the future.

This thing, if both the machine equipment and the algorithm data are abroad, then people can really control your every move, which is much more serious than a bottleneck.

The current layout is mainly about the layout of talents. There will be a huge demand for engineers in this area in the future, but few universities can really train them. What's more, artificial intelligence does not only have one neuron path, can other paths really not be taken? , schools and professors must try it.

The laboratory he set up was based on this idea. Currently, all graduate students are trained. Their names are not under Wang Xu's name, but are scattered in various departments of Shuimu, but they are all trained here, even some from other universities. Graduate students are commissioned to be trained here.

Professor Luo only has two graduate students and one doctoral student. After filming the movie next year, Wang Xu will also recruit the first batch of doctoral students. The plan is to have two people. These people are the seedlings of future research on artificial intelligence.

There is a need for exchanges between schools. A large number of Shuimu graduates will go abroad for further study. At least in Wang Xu's view, this is not a bad thing. There are indeed many things that they are leading.

But that's not the case at Wang Xu's place. This place is already the top in the world, so the admissions review here will be particularly strict. Even Wang Xu is not qualified to intervene, and there are no quotas for international students.

Unlike scientists who are purely theoretical, Wang Xu has too much engineering practice here, and he can use it directly when he takes it back.

Pure artificial intelligence theoretical research is actually not very worrying. Most of the algorithms in this area are public and not very complicated.

But this is not the case with large data models. In many cases, it really depends on luck to train them. Many of them are just tried and tested, and they cannot be handed over to others casually.

Anyway, the current security and review of Wang Xu's laboratory is really very strict, not inferior to the confidential department of the top digital research institute. However, Wang Xu, the person in charge, is floating outside all day long, making it very difficult. It's a headache.

But the superiors really spoiled him, just letting him do whatever he wanted, and wiping his butt. Therefore, they gave outsiders the illusion that Wang Xu's laboratory seemed to be very ordinary, no different from the ordinary Shuimu Laboratory. Big difference.

But in fact, there are already arrangements for who can come and who cannot come. There are rules for who can enter which room and who can be seen, but they are not exposed outside.

Of course Wang Xu knew this, so he accepted it with peace of mind. He did not intend to remain completely anonymous. Even if he had the skills and system, it would still require a lot of communication and a lot of collaboration to complete most things.

He is not one of those math geniuses who can conquer the world with his clever brain. He really doesn't have this ability.

"Are you here to communicate with Wang Xu today? Or to apply for funding?" After chatting for a few words about Wang Xu's gossip, Director Jiang brought the conversation to the main topic. He was also busy.

"I have them all. When I came here, I heard that he disappeared again. There are some features on the flight control model, so I have to discuss it with him.

I don’t have enough data here and I don’t have enough computing power, so I still have to apply. "Professor Luo immediately explained the purpose of his visit. He was really not someone who just came to chat. He came with a teapot in his arms just to discuss the issue of model design with Wang Xu.

"It's already January. Although he will definitely be back before the end of the month, he may not be able to spare the time. The funds are easy to talk about, but it's useless to give them to you now. He said that an important reason for going to the northwest this time is to collect data. , he said it’s windy over there.”

"Without data, it's useless to ask for funds, so let's wait until he comes back. I've been busy for a year now, and I have two days off. I can't let the boss take a break, and it's not just the employees who are busy." Professor Luo hehe He smiled, with a proud look on his face.

He can really be proud. The person he is now is completely different from what he was two years ago. An internationally renowned expert on artificial intelligence algorithms, one of the founders of neuron theory, and the first person in China to deepen algorithms in this field.

Unlike the professor in Chou Country in his previous life, who had been working hard for many years and only published papers, Professor Luo has made some small achievements in training. His accuracy in recognizing printed English is already quite high, at least not as good as several other artificial intelligence paths. Difference.

Although its recognition algorithms and models currently have no effective applications due to high computing power requirements, some bright prospects can be seen.

In the field of artificial intelligence at this time, convolutional neural networks are not a mainstream research direction. Therefore, although Professor Luo has made many achievements, they are just that in the eyes of the world.

Of course, this is also related to Wang Xu's conscious control of the speed of publishing papers. He still hopes to hide his capabilities and bide his time for a while. They are now overwhelming China in terms of financial resources, equipment, and even talent reserves.

If the prospects of this road are opened too early, it will actually be very detrimental to China. Professor Wang Xu and Professor Luo will have to suppress the progress. Research will make great strides and papers will be published slowly. This is probably the pattern.

Just like the artificial intelligence learning in the flight control part, the paper may not be published in ten years, let alone open source and shared.

At this moment, Wang Xu was in the northwest, among the Gobi hills near Dunhuang, braving the strong wind, pulling Wang Fei with him to observe several cameras flying in the sky.

Of course, it was brought up by the drone. It can be regarded as a joint debugging. If it can still fly stably in such a windy environment, then it can be finalized. As for obstacle avoidance, it is better to rely on people to avoid it first.

Wang Fei was completely wrapped into a ball by Wang Xu, wearing a down jacket, a down hat, and a gauze scarf. Her slim figure was no longer visible at all, but it still couldn't interrupt Wang Fei's excitement when she saw the desert for the first time.

Of course, this is what typical foreign tourists think, what a spectacular, desolate, vast, all kinds of beautiful adjectives. But in the eyes of the locals, it is only cold, brutal and painful.

The northwest is not a land suitable for living. Thousands of years ago, it was an oasis. Now it is not completely green, but a little further away from the water source is the desolate Gobi.

The real ancient city of Dunhuang has long been in ruins. The current ancient city of Dunhuang is actually a film and television city. It was built a few years ago when I collaborated with Xiaozi to film "Dunhuang". Later, it became a film and television city, specially used to film various scenes in the northwest desert. scenery.

"New Dragon Gate Inn" was filmed here, but Wang Xu didn't need the scenery here. All he needed was the desolate desert. In fact, it was the part outside the film and television city, but some of the supporting facilities in the film and television city itself could still be used. Use it.

There is a national geological park here that will be well-known in later generations, with the famous Yadan landform, but it is not well-known at the moment, and the country has not spared any effort to protect these places.

Wang Xu is now preparing for tomorrow's aerial photography, which should be enough to express the sad atmosphere of the apocalypse.

Wang Xu only needs big scenes here, no detailed performances, just a motorcycle running out of smoke and dust on the ground. Therefore, Wang Xu plans to take some material back this time. Although the season is not right, he might be able to Works wonders.

Wang Xu’s original plan was to take pictures after spring, when there are strong winds, especially sandstorms. It felt more right. This time, although it was deserted, it was not cold enough. It was not the cold weather. In fact, the temperature was already below zero.

What I’m talking about here is the cold color. The northwest desert under the sun always has a warm tone, regardless of winter or summer, and regardless of the temperature. This kind of color is not very suitable for the somewhat cold tones of the entire movie "The Matrix", but the golden afterglow at sunset is an excellent atmosphere for showing the dawn.

This is ideal for showing Xi'an's position in people's minds, a ray of sunshine in a cold world, with a touch of dreamy sunshine.

This kind of contrast under the lens can convey an emotion to people unconsciously. This is the so-called lens language.

Of course, this is just the simplest one. There are also the use of lenses, filters, cuts, etc., which are all the language of the lens. This is the role of the director. He uses this special language to lead the audience to use it. A dream journey is completed one shot at a time.

Several drones have been recovered, the sun has finished its work, the sky has turned dark, and the surroundings are deathly quiet.

The wind is very strong today, there are almost no clouds in the sky, it is dry and cold. As the last ray of sunshine in the distance dissipates, the vast Milky Way gradually reveals its beautiful shape.

This is the charm that belongs only to the wild. People who were born in the city will never have the opportunity to see this stunning starry sky in their lifetime.

Wang Fei had laughed at Wang Xu, saying that she looked up at the stars all day long, but in the end she had never seen a few stars, which made Wang Xu hatefully drag Wang Fei to the northwest to drink the cold northwest wind and watch them together. The vast Milky Way.

Of course, you don’t have to be so masochistic to look at the stars. Isn’t this just catching up?

What's more, they also have sleeping bags made of new thermal fibers sponsored by the Department of Chemical Engineering, and tents made of new high-strength hydrophobic fibers. Once inside the tent, there really was no wind at all.

The transparent dome is a new type of transparent plastic sheet, which is a modified plastic. Although it is only such a small piece, it was temporarily obtained from the laboratory.

The tensile strength of this thing is dozens of times that of ordinary plastic sheeting. It is actually a very ideal space material. Wang Xu's use of it to make a tent here is overkill.

But who calls him Wang Xu? These projects were all created by him. It doesn’t cost money to find someone to make a film, not to mention making tents or underwear.

Of course, this time, Wang Xu brought a lot of new and good things, not to mention drones, new cameras, new SLR cameras, new lenses and other professional equipment for making movies.

Just look at the pile of equipment on his body, such as lithium battery-driven light-emitting diode headlights, micro-mechanical chip-driven digital altimeters and compasses, ultra-high-strength safety ropes, aviation aluminum-lithium alloy hooks, There are also ultra-thin barbecue grills made of high-strength stainless steel.

Even the pathfinding pole in Wang Fei's hand is made of the newly developed 1400T carbon fiber. Even though it weighs less than a pound or two, it is easy to insert it into the rock crevice and stand upright.

Anyway, adhering to the spirit of using a cannon to swat mosquitoes, Wang Xu brought his hiking suit regardless of the cost.
