Every time he lay down or opened his eyes, Shen Qingmeng always wanted to send a message to Ji Xinghe, which also became a habit.

She lies on the bed and lights up her phone.

"Brother Ji, I've lost a lot of weight, Yang Li said that I look a little scary now, what if I don't look good?"

After typing this line, he clicked on the camera again, ready to take a selfie and send it to Ji Xinghe. But looking at the face in the camera, Shen Qingmeng felt very unfamiliar.

is like a seriously ill patient, except for being in good spirits, he looks completely terminally ill.

It seems to be really ugly.

Shen Qingmeng was a little frustrated, he didn't know what Ji Xinghe was like now, so don't scare him.

Tap Send, then put away your phone and sleep.

The nap was not long, but Shen Qingmeng felt that he had had a long dream.

There were all kinds of bizarre scenes in the dream, and when she woke up, she couldn't remember the things in the dream.

She sat on the bed with the quilt in her arms for a while, intermittently remembering some incoherent fragments.

In the dream, she walked in an endless black forest, and the ground was soft and dirty, and every step would sink into it, which was very laborious. Shen Qingmeng couldn't tell the direction, so he could only grope his way forward.

The sky was snow-white, but the light was very gloomy, Shen Qingmeng walked alone for a long time, she didn't know where she was going, she didn't know what she was looking for, she only knew that she had to get out of this forest. But the size of the forest is terrible, and the world is silent and terrible.

Shen Qingmeng stumbled under his feet, and a dry branch pierced into his ankle. There was no pain, but colored blood flowed. The color of blood is very bright, and it is the only fresh life in this dark world.

Blood trickled down the ankles and fell to the earth, coloring the monotonous land. Shen Qingmeng stared blankly, not knowing why the blood that came out was colored. It's obviously a very grotesque scene, but I feel that this is normal.

As the blood flowed more and more, the whole world began to come alive and bright, with turquoise meadows, thick green leaves, blue skies, and a faint fresh smell of wind. Brighter and brighter, bright to the extreme, to darkness.

It's not pure darkness, because the inky black sky is dotted with cold stars one after another.

They emit a bright, cool light. Although there were no expressions or words, Shen Qingmeng could feel their acceptance as a kind.

Similar.

Shen Qingmeng lowered his head, and it was not surprising to see that he had also turned into a star. Bright white light radiated from himself, illuminating this small piece of sky.

A star flew over beside her, looked around her twice, and opened Lin Jing's voice: "My name is Lin Jing, Nancheng No. 1 Middle School." ”

It was as if the soul had been withdrawn and drifted to the side to watch the scene in the dream. Shen Qingmeng smiled, this young master was still so proud in his dreams, only those who could see it could be accepted by him as his kind. He looked at her in a circle, as if judging whether she was qualified to be his companion.

Shen Qingmeng saw the star representing him, shook the spot slightly, and suddenly accelerated and rushed forward, bringing out a long line of cold tail light. Lin Jing's star was not to be outdone, and immediately caught up. The two stars seem to be popular, and they cross the sky very quickly, and you chase after me and disappear.

The fragmented memories of these dreams are barely pieced together into a complete dream, and there are more wonderful and treacherous pictures, which have disappeared into the depths of memory and cannot be found.

It is said that dreams reflect the subconscious, Shen Qingmeng examined this dream again, and he really wanted to conquer the stars and the sea.

A person's loneliness, always walking alone, needs to light up the whole world with blood in order to see the broader universe. Exploring the endless universe is the common goal of many people like stars. Each person will illuminate their own realm, and they will also walk through the realm illuminated by others, and these lights will intertwine to uncover more of the unknown of the universe.

It really sounds like a primary school student's proposition essay "My Ideal", and it also looks like the expectations of a hot-blooded teenager in Secondary 2 for the future.

The ringing of the alarm clock interrupted Shen Qingmeng's thoughts, half past one in the afternoon.

The lecture started at two o'clock, Shen Qingmeng washed his face, tied his hair back up, and walked out of the dormitory building.

The midday sun in midsummer is very strong, and the heat is amazingly high, and the air is distorted with light and shadow.

Yang Li and Lin Jing were already standing under the tree in front of the building, talking something.

Shen Qingmeng walked over quickly, Lin Jing snatched the folding fan in Shen Qingmeng's hand, and shook it vigorously while complaining: "You are too slow, I don't want to wait for you if you don't come out again." ”

Regarding Lin Jing's complaints, Shen Qingmeng has evolved from fighting two sentences at the beginning to being a deaf ear now, and just asked Yang Li: "Have you waited for a long time?" ”

Yang Li glanced at Lin Jing with a smile: "It's not long, a few minutes." ”

"Hey, where are you?" Lin Jing was dissatisfied, "From the perspective of relativity, a few minutes is already a long time in such a hot weather. ”

By the time I walked to the auditorium, I had almost arrived.

The organizers of the summer camp invited several chair professors are very qualified, so that students who are not in this discipline can also feel the wonders. So every time I gave a lecture, everyone was very positive.

The professor sitting on the rostrum is none other than Shen Qingmeng's enlightenment teacher of the computer, Professor Han Zhengqing.

Professor Han is the same age as Lao Shen, unlike Lao Shen, who is well-maintained like a star, he looks like a typical scholar. White shirt and black trousers, slightly fat, very kind smile.

As usual, Xia Weimin opened the lecture, briefly introduced Professor Han, and began the lecture.

"Hello students, I am today's keynote speaker, Han Zhengqing. You should be curious, I, a professor at Beijing University, came to Nancheng to give a lecture. I am here thanks to my colleague and long-time friend Professor Shen Yi. With his strong recommendation and fooling, I became the keynote speaker of this lecture. ”

Speaking of this, the students in the audience began to chuckle, which showed that Lao Shen still left a very deep impression on everyone.

"Just now, I flipped through your monthly exam papers, and your level has exceeded my imagination, so I know that I listened to Professor Shen Yi's recommendation and was not fooled."

When he was flipping through the test papers just now, Xia Weimin had already pointed out a few top-notch students to show him, and Shen Qingmeng's name was impressively listed. He had read Shen Qingmeng's test papers, and in the past half a year, Shen Qingmeng had not been wasted, and there had been a lot of progress compared to when she left the capital.

Professor Han looked at the more than 100 students in the audience one by one, and easily found Shen Qingmeng, but her current thin appearance was almost unrecognizable.

"I don't have a better level to teach you than your instructors in the competition course, so I decided to tell you some lovely things about computers and artificial intelligence. What do you think intelligence is? ”

The audience gave all kinds of answers, and the computer students were especially active, and even gave a lot of brain-opening answers.

Professor Han listened patiently and then said, "For example, for a column of numbers, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, then what are the next numbers? ”

"89." The students in the audience said in unison.

Professor Han smiled: "That's right, this is the Fibonacci sequence. You have learned about it, or you have just drawn the results from the laws of numbers, and your thinking process is intelligence. The cognitive ability of people to learn from experience, to think rationally, to memorize important information, and to cope with the demands of daily life is what we call intelligence. So how do you get the computer to output the next number? ”

Shen Qingmeng and Lin Jing involuntarily took out a pen and paper and wrote code on the paper. Most of the students in the computer competition did the same, taking out a pen and paper and starting to write.

After waiting for a while, Professor Han continued: "You can use java, you can use C++, you can use python, you can use array methods, you can use flat push methods, you can use recursive methods, in short, there are many paths that can be achieved. This process is the process of giving the computer to think. The computer will calculate and output the result of the problem we want according to the rules we have made, so does this mean that the computer is intelligent? ”

Hearing this, Lin Jing muttered to himself: "Turing test." ”

Whenever the difference between humans and machines is mentioned, the Turing test cannot be avoided.

In a room with a central curtain, there is one person on each side of the curtain, one of whom is the inquirer. The questioner must determine whether the person on the other side is a man or a woman, and complete the task by asking a series of questions. It is assumed that men will lie and women will be honest. If the person on the other side of the curtain succeeds in deceiving the inquirer, then he wins.

This test, in turn, extends to machine intelligence testing.

"If an inquirer, by asking a question, sends a test to the person behind the curtain or to the computer to determine whether it is the person or the computer who answers the question. What questions do you ask? ”

The audience raised various questions again, such as "ask him what it feels like to be in love", "ask him what the result is ×3690153 17469", etc., mixed with the voices of his peers to refute, and the auditorium was discussed.

After waiting for a while, Professor Han motioned for everyone to be quiet: "Everyone's thinking is nothing more than two directions, one is to detect whether the computer has subjective will and emotions, such as whether it will be scared and how to look at a certain problem, and the other is to detect rapid and accurate calculations that cannot be achieved by humans." But as you just discussed, there are ways to circumvent these problems. For example, a computer can record a human description of fear, an opinion about a problem, or give an incorrect answer to a calculation. This is a game of humanity itself. “

On the one hand, people do as much pre-programming and learning training as possible, and on the other hand, they try to find out what the computer is different from humans as much as possible, then improve the training, and then find out the problems, and so on.

"We look closer to the present. Not so long ago, we were saying that computers were not as good at recognizing and thinking as a one-year-old child. In the future, what kind of recognition and thinking level do you imagine computers can achieve? ”

That's a big proposition.

Although many movies give a lot of brain-hole assumptions, from a scientific point of view, these assumptions are not rigorous. So, what kind of recognition and thinking level can computers of the future achieve?

There was silence in the auditorium.

Professor Han was still smiling and looking at the thoughtful faces in the audience, as if the question asked by the tutor to them back then, is the computer intelligent? Is it possible to think like a human?

He and his classmates also had such thoughtful expressions.

No one answered.

"We've imagined a lot that driverless cars, robots that work day and night, housekeepers, and even art can be done by computers. Human beings have ideas, and they turn those ideas into methods. These methods can be represented by algorithms, heuristics, programs, or programs that act as the backbone system of a computer. In the end, we get the product of the machine, which we call the result. People, Idea, Method, Machine, Outcome, these together make up what we call artificial intelligence. “

As Shen Qingmeng once thought, there were no workers in the factory, no teachers in the school, and everyone had a personal housekeeper at home. Under Professor Han's narration, these are like a magnificent picture, slowly unfolding in front of everyone.

When giving Shen Qingmeng an enlightenment lesson, Professor Han also said this. Shen Qingmeng, who was ignorant at the time, was not as shocked and touched as he is now. The more you study, the more you can comprehend the mysteries of the vast sea of smoke, and the more you feel small.

Lin Jing beside her is also like her, immersed in the prospect of the future, and his eyes are shining. All of you here, why not?

The future that truly changes the way of life is not the unattainable spring and snow, but the changes that are within reach around us, and who can not yearn for it.

Professor Han's gaze fell on Shen Qingmeng again, as if he and Lao Shen were looking at each other from a distance across half of the auditorium that day.

If the encouragement that Lao Shen gave her was the spiritual encouragement emanating from herself, the future described by Professor Han was a wave rolling up from the outside, enveloping her and moving forward quickly.

There was no question session at the end of the lecture, and most of the interaction was completed in the course of the lecture.

Xia Weimin took the stage to announce the end of the lecture, and the entire auditorium was silent for a few seconds before bursting into deafening applause.

After the students left the venue one after another, Shen Qingmeng and Lin Jing were called to stay.

In an office, Xia Weimin sat with Professor Han on the side, and the table was spread out with their monthly exam papers.

Seeing the two of them walking in, Professor Han greeted Shen Qingmeng with a smile on his face: "Mengmeng, come." ”

Shen Qingmeng walked over as she said, and Professor Han nodded her test paper: "Old Shen said that you are not in a good state, let me encourage you, I see that your paper answers are very good, there should be nothing bad to adapt." It's just that you've lost too much weight, isn't it stressful? ”

Shen Qingmeng was praised and sprinkled two sentences, which amused Han Zhengqing.

After saying a few words, he looked at Lin Jing again: "Your test papers are also very good, and your basic skills are very solid, but you are a little lazy in answering questions and don't want to think too much." ”

Shen Qingmeng and Yang Li have both said this question, and now that Han Zhengqing pointed it out, Lin Jing blushed a little: "Thank you Professor for your advice, I will pay attention to correcting it." ”

"I heard from Mr. Xia, you are all good seedlings of this summer camp, I look forward to seeing you in the national training team during the winter vacation, and you are also welcome to apply for Beijing University."
