Chapter 19 It’s broken, he seems to really understand

A high-end community in Haicheng.

A greasy man in his thirties with a high hairline was sitting in front of the computer, watching the live broadcast of the top movies and TV shows with great interest.

He is Ma Yong, a well-known domestic science fiction writer, the scientific consultant of the movie "Love in the Stars", and the original author of the novel.

"Oh, even if you do some silly gimmicks and develop your own AI, do you know what AI is?"

Ma Yong wanted to laugh when he saw Xu Nuo saying in the live broadcast room that his company developed an artificial intelligence on its own in order to film "Terminator".

This is obviously a trick used to fool netizens.

When Xu Nuo mentioned in the live broadcast room that the artificial intelligence they developed has the most advanced AI technology, Ma Yong laughed even louder.

I saw him taking out his mobile phone, opening the Weibo APP, and the editor posted a Weibo post——

"How does a young director understand what AI is?"

It also included a picture of a robot that he had previously asked an artist to customize.

"no problem."

"When will Dr. Ma's new book be released?"

Zhang Chaowen asked with increasing interest: "Can you tell us about this convolutional neural network and deep learning?"

"I took a look, "Love in the Stars" and "Terminator", both science fiction movies will be officially released on June 16, right?"

"It's really not easy to shoot a lot of scenes, and it's a science fiction movie. Let's take a look at what netizens say. You can see that many netizens are very concerned about what you did to film this "Terminator"

There is artificial intelligence, and some netizens have questioned it, saying how can you, a film and television company, be able to create artificial intelligence?"

They even helped Xu Nuo give a more intuitive explanation to other confused viewers in the live broadcast room.

Xu Nuo looked serious about popularizing science, just like a university professor who was concentrating on his class.

"One thing to note, I saw the trailer for "Terminator" and it actually looked pretty good."

"I'm laughing so hard. You have the world's best artificial intelligence. Why doesn't he go to heaven?"

When they hear Xu Nuo’s popular science, they will feel very friendly.

In the live broadcast room of TOP Film and Television, there are still a few professionals who are relatively knowledgeable about related technologies in the field of artificial intelligence.

Real Film and Television Technology Company.

"My dear, Director Xu looks like a professional player!"

"You know, AI painting, which was popular before, is a computer deep learning model."

Xu Nuo said calmly.

“As a student majoring in artificial intelligence, listening to Director Xu’s lecture on convolutional neural networks makes me feel like I’m back in a university classroom.”

"Yes, we did the actual shooting in Yuzhou City. We didn't even use the studio very much. We basically used real-life shooting."

"Are you talking about Xu Nuo, the director of "Terminator"? I am watching the live broadcast of Top Film and Television."

So I gave Zhang Chaowen and the audience in the live broadcast room a brief science introduction: "The convolutional neural network algorithm actually imitates human visual perception. We use the function of the convolutional layer to extract features from the input data.

"Dr. Ma, who does this mean?"

"Actually, like the superposition of deviations that Director Xu just mentioned, this increases the number of solution steps and does not facilitate the solution of parameters."

Xu Nuo nodded slightly and replied.

"Released at the same time? Let him break when touched!"

I was thinking, Director Xu, would you like to see what you are talking about?

In the film and television TOP live broadcast room, netizens were completely dumbfounded, and the barrage "?????" had already flooded the screen.

"When I'm in the live broadcast room, I feel like that guy is pretty good at bragging."

Nowadays, with the advancement of CG special effects technology, there are fewer and fewer directors who can insist on real shooting. After all, setting up a studio for shooting and then using post-production special effects synthesis has become the mainstream of filming film and television dramas.

"We have also made proportional models of robots, including spaceships, tanks, firearms, etc. in future wars. We have also made a large number of model props."

"What about the robot in the trailer?"

The convolutional layer contains multiple convolution kernels, and each element that makes up the convolution kernel corresponds to a weight coefficient and a deviation, which is similar to the neurons of a feedforward neural network.

Soon, in the comment section of Ma Yong's Weibo, there were many fans of Ma Yong's books, as well as fans of the movie "Love in the Stars", and fans of the male and female protagonists commented in succession.

He just stood there in a daze.

"It seems that our director Xu really likes real-life shooting. Even artificial intelligence can actually do it, so traveling through time and space cannot be real-life shooting, right?"

"Who is Lao Ma talking about?"

"Are most of the shots real-life?"

Ma Yong had no other intention, he just wanted to express some connotations about Xu Nuo.

"As a recent graduate of Artificial Intelligence, I will give you a brief explanation. What Director Xu said is probably that the convolutional neural network algorithm can allow computers to have visual perception similar to humans, that is, image recognition, speech recognition, machine translation, etc.

of deep learning.”

"Dr. Ma, why don't you just go away and write code? Why are you dissing people here again?"

"Hahahaha, that's naturally impossible, but when it comes to traveling through time and space, we use Einstein's wormhole theory to create a rendered space-time tunnel visual effect."

"It seems that Director Xu is very knowledgeable about artificial intelligence, right?"

Xu Nuo said seriously: "After all, it is too expensive to produce top-notch special effects. The special effects we used in "Terminator" are actually not many, and we mainly rely on real shots."

"Please look forward to the release of the film adaptation of Dr. Ma's masterpiece "Love in the Stars" on June 16th!"

"Damn it, I was dumbfounded by this. Did Director Xu study artificial intelligence before?"

"I've never heard of the director Xu Nuo, and I've never heard of the actors used in the movie. They're mostly just amateurs."

Zhang Chaowen continued to ask.

"He's just riding on the popularity of Dr. Ma's "Love in the Stars"."

Zhang Chaowen said jokingly, livening up the atmosphere in the live broadcast room.

Therefore we can list a linear convolution formula: y(n)=x(n)*h(n)=∞∑k=-∞x(k)h(n-k).

In this way, each neuron in the convolutional layer is connected to multiple neurons in closely located areas in the previous layer. The size of the area depends on the size of the convolution kernel. This is a kind of "receptive field", which can

The analogy is the receptive field of our human visual cortex cells.

The reason why Xu Nuo said that special effects are too expensive is actually laying the groundwork for his company to do special effects business in the film and television industry in the future.

Everyone in Zhang Chaowen was already stupid.

"In fact, artificial intelligence is not that difficult to do. Simply put, mathematics and computer programming technology are the basis of artificial intelligence. At this stage, the AI ​​we apply in the field of artificial intelligence are usually based on convolutional neural network algorithms.

Deep learning performed.”

When the convolution kernel is working, it will scan the input features regularly, so within the receptive field, a matrix element multiplication and summation can be performed on the input features and the deviation amount is superimposed——

"Aba Aba???"

There are already tens of thousands of netizens watching in the live broadcast room.

"Director Xu, I can see from your trailer for "Terminator" that many scenes were shot in real life. Were we filming in Yuzhou City?"

"We used a professional team of blasters and spent a lot of explosives to actually shoot every explosion shot in this movie."

Zhang Chaowen told Xu Nuo some of the doubts raised by netizens.

"Yes."

Xu Nuo began to use a professional perspective to tell those who doubted whether he understood what artificial intelligence was.

Xu Nuo answered firmly.

When the convolution kernel is of size f=1, stride S0=1, and does not contain a padded unit convolution kernel, the cross-correlation calculation within the convolution layer is equivalent to matrix multiplication, and thus constructed between convolution layers

a fully connected network”

In Xu Nuo's office, Xu Nuozheng and Zhang Chaowen were chatting about the story behind "Terminator" in his film and television TOP live broadcast room, from the artificial intelligence adaptation to the efforts of the crew, the seriousness of the actors, and the actual shooting of the camera.

"Are the explosion visual effects shots in the film all real explosions?"

Xu Nuo nodded slightly, indicating that this was a professional conversation.

Zhang Chaowen asked slightly surprised.

At this time, the science fiction writer Ma Yong, who was far away in Haicheng and was watching the live broadcast, suddenly felt nervous and felt something bad. Damn it, this Xu Nuo, he seemed to really understand AI.

The next second, Ma Yong immediately took out his phone and clicked on Weibo, deleting the Weibo post he had posted earlier with the connotation of Xu Nuo at the speed of light.

Hehe, as long as I delete Weibo quickly enough.

If I slap him in the face, he won't be able to catch up with me!
Chapter completed!
