Chapter 170： Lesson 1

Time flies, two days have passed.

Xiamen University, the third teaching building, a large ladder classroom.

The students came to class one after another. However, at the entrance of the lecture hall, two mobile phone racks were specially placed, and two staff members were standing by to collect the smartphones and other electronic products from the students.

"What's the matter! Do you still have to collect your cell phone in class?"

"I'm going! I'm going! I'm so surprised, isn't it really Mr. Li who is here?"

"Why do you want to accept mobile phones! Afraid we take pictures and videos?"

"The teacher who teaches this class is definitely not easy. Otherwise, is it necessary to accept mobile phones in open classes?"

...

The students lined up to turn in their mobile phones, all of them were excited and talked a lot.

Their mobile phones were confiscated in class. It was still in high school. When they were in junior high school, after they went to college, they all depended on their own self-consciousness. The school would hardly control their use of mobile phones. Zhan, for a time, all the students found something unusual.

"Hurry up, class time is almost here, hand over your mobile phone soon!"

"I told you, don't send random news about today's class, or you will be punished. If you have to go to class, quickly put your mobile phone on it and take it away after class!"

Two staff members gave a stern warning, urging students to turn in their mobile phones.

"Sister, this battle! It's very likely that President Li is here to teach, haha, we're here!" Zhou Wenbin, who was in line, excitedly introduced to Zhou Wenhui, who was in front of him.

Zhou Wenhui's eyes are bright, and she is indifferent. At this moment, she also has a kind of excitement to see a 'celebrity'.

The students in the queue, with excitement, turned in their mobile phones to enter the large amphitheater.

After a while, a large group of students who received the news came from all directions.

The school had already anticipated this situation, and set up staff blocks at various intersections. Except for the students who signed up for the course, no one else could pass.

Soon, the large amphitheater was filled with eagerly-awaited students.

The class bell of "Lingling" rang, Li Yi held a document and a thermos cup in his hand, walked into the lecture hall with a smile, and walked straight to the podium.

The classroom suddenly fell silent, and 120 pairs of eyes stared at him, showing faces of surprise and shock.

Li Yi is wearing a pair of blue jeans, a plaid long-sleeved shirt, and a black down vest. He is tall and slender, with a beautiful face, showing a sunny smile, and his short, broken hair looks smart and capable. Brother Sunshine from the neighbor's house is about the same age as them.

However, this 'familiar' face has been revisited again and again in hot news searches, and has been dubbed by various names: the father of artificial intelligence, the father of virtual networks, the father of virtual games, the richest man in the world, the most outstanding The young scientist, ..., etc., he is not only a celebrity, but also the founder of the fifth scientific and technological revolution in human society.

Now, he appeared in the classroom and will teach them a lesson. All the students were stunned for a moment, and they all responded,

"Clap clap clap..."

I don't know who got up first, the applause suddenly sounded, and then it became very intense, like a tsunami.

"Thank you, your applause, the class starts now!" Li Yi stood on the podium, waved his hand with a smile, and announced.

Hearing this, the students stopped applauding one after another, and those who opened their diaries and those who wrote down quickly entered the learning state.

"From the applause just now, it can be concluded with a high probability that you all know who I am, so I won't introduce myself anymore." Li Yi explained with a smile, and then changed the wind and began to lecture: " The judgment I made can be qualitatively called: subjective judgment, then, a program with this 'subjective judgment' ability can be qualified as: artificial intelligence."

Hearing this, the eyes of the students in the audience lit up. Li Yi used an example that just happened, and at once, pointed out the difference between artificial intelligence and other computing programs for them. It was clear at a glance.

"The content of this course is simple and simple, and difficult to say. The birth and evolution of artificial intelligence is a very profound knowledge. Even if I spend my whole life, it is difficult to study it thoroughly. I teach this course. The purpose is to let more people understand artificial intelligence, apply artificial intelligence, and make more people interested in it and devote themselves to this science. Therefore, I will only talk about some basic things in the class, and those who are interested in the field of artificial intelligence Classmates, you can go deep into the research and discuss with me." Li Yizhan smiled and introduced the core of the course.

"Today's first lesson, the content is: the 'birth' of artificial intelligence. Like human babies, the birth of artificial intelligence is gradual, starting from 'imitation learning', ..., in the early stage, computer programs, set according to human beings The rules and summary knowledge operation, however, can never surpass its creator, and secondly, the labor cost is relatively high.”

"Next, it is machine learning, which represents the system: perceptrons, neural networks, ..., the third generation of technologies developed, statistical learning methods began to occupy the mainstream stage, and representative methods include support vector machines, ..., fourth Generation artificial intelligence technology: AI learning network constructed by big data network, deep construction of neural network, convolutional neural network,..., fifth generation artificial intelligence technology: simulation learning, that is, building an ecological learning system..."

"Students who are interested in building a bionic learning system with point-to-point systems can learn by themselves the Chinese compiled language developed by Xingyao Technology. This is a language suitable for developing artificial intelligence, and it is also suitable for building virtual networks. program."

...

Li Yi eloquently introduced the basic knowledge related to artificial intelligence development, and guided students to get started step by step.

With Li Yi's explanation, the content gradually began to become esoteric.

The huge disintegration classroom was quiet, only the "rustling" was left. The ballpoint pen wrote the sound of drawing in the diary Zhou Wenhui did not take notes, and stared at Li Yi's face with bright eyes. , listening to his thick and magnetic lecture voice.

In order to take care of them, Li Yi's content is relatively basic, and Zhou Wenhui can understand this knowledge.

If Li Yi noticed something, he glanced at Zhou Wenhui and recognized her at once.

There are 120 students in the grand amphitheater, and girls account for about one-third of them. However, among all the girls, Zhou Wenhui is the most outstanding, with an oval face, red phoenix eyes, pale skin, and a green and sweet face.

Li Yi stopped the lecture, looked at the audience, and asked with a smile, "I've covered a lot of content, but I don't know how you listened. It's almost time to interact. Do you have any questions? If you have any, just raise your hand and ask."

As soon as Li Yi's question fell, the professor suddenly became quiet, and the students looked at each other, but no one asked any questions.

"Me! Teacher Li, I have a question!" At this moment, a crisp and pleasant voice sounded.

Everyone looked around, and they all saw a white temporary arm, held high, a beautiful and confident girl.
