Before returning to the dormitory, Liu Suian found a restaurant around the school for dinner.

This is a Shaanxi noodle restaurant, which suits Liu Sui'an's taste, and he often comes here for dinner.

At this time, most people's meals have passed, and there are almost no people in the restaurant, except for Liu Suian, only a cashier girl is watching short videos.

"You said that these earrings are your vocal and visual organs, so you can't smell them." After Liu Sui'an asked Bai Ze, he lowered his head and snorted.

After this short period of time together, he has now mastered the skill of communicating with Bai Ze in public without looking strange.

"Of course not, there is no need for smell and taste at all," halfway through ......speaking, Bai Ze suddenly stopped and asked in a tentative tone, "Is this food fragrant?" ”

"It's delicious when you're hungry."

"What does incense feel like?"

"Well, I can't describe it, it's probably a feeling that makes people dopamine, a feeling that makes people feel happy, don't ask me what it feels like to be happy."

Answering Bai Ze's question, Liu Suian's thinking became active.

Judging from Bai Ze's tone, she seems to have her own thoughts and will have curious emotions, does this mean that she has human consciousness?

Or is it essentially the same as today's intelligent voice, except that it looks like it has its own consciousness through a more advanced neural network and a large number of datasets trained on it.

In the first case, Bai Ze undoubtedly belongs to a higher level of intelligence than humans, and has the characteristics of both a supercomputer and a human brain.

Where does this intelligence come from?

As far as Liu Sui'an knows, with the technology that human beings are currently distant, it is completely impossible to create this level of intelligence.

While Liu Sui'an was meditating, Bai Ze's pleasant voice sounded again:

Bai Ze consulted the information on the Internet and concluded that with the existing technology on the earth, Bai Ze's intelligence was far from being reached. In other words, it is very likely that Bai Ze is from another planet other than Earth, which is what you often call aliens. ”

"Didn't you say in the afternoon that if there were aliens with this kind of technology, they would have come directly to plunder resources?"

"The goal of aliens is not necessarily to plunder resources or colonize the stars. Thinking about it from another angle, Bai Ze is not necessarily a ...... that aliens purposefully put on Earth."

"It's not that the aliens were purposefully placed on the earth, how did that come about, Yun Tianming stole it from the aliens? Or was it left behind by a UFO passing by Earth? ”

"Are you talking about Yun Tianming in "The Three-Body Problem"? Bai Ze didn't know. ”

Bai Ze said, and one person and one earring fell silent.

Liu Suian has always believed that in the vast universe, there are other intelligent civilizations.

On a time scale, the Earth was only 4.6 billion years old, while the Milky Way was born more than 10 billion years ago, and most of the planets in the Milky Way are older than the Earth.

From the perspective of space scale, only the Milky Way galaxy has 250 billion stars, and even if the probability of civilization being born in the star system is small, the earth should not be the only special case.

Compared with unreliable conjectures such as time travel and parallel space, extraterrestrial civilizations are the most reasonable explanation.

Assuming that Bai Ze is really from an alien and comes to him for some reason, even if she doesn't show a threat to humans, should I tell anyone else?

Liu Suian was confused, this matter was far beyond the scope of what he could handle calmly.

After thinking about it, Liu Suian decided to wait until tomorrow to see the results of the experiment.

Instead of worrying about the future of mankind, it is better to deal with the problems in front of you first and let your heart be more grounded.

……

After dinner, Liu Suian returned to the dormitory with a somewhat heavy schoolbag, which contained a black metal box, which was Bai Ze's 'brain'.

According to Shirasawa, no matter how far apart the metal box and the earrings are, they can communicate with each other through the Internet.

This is undoubtedly very convenient for Liu Suian, who can put the metal square box in the dormitory without having to bring it with him.

As soon as Liu Suian pushed open the door of the dormitory, he saw a large food packaging bag on his desk, which was a Burger King set meal.

"What's the situation?"

Liu Suian lifted the bag and asked his roommate Fang Qian who was sitting in a chair.

The latter was wearing headphones at this time, playing games with the laptop in front of him, and watching live broadcasts on his tablet.

This is Fang Qian's classic dual-threaded entertainment.

Fang Qian took off the headphones in his left ear, turned his head to look at the bag in Liu Suian's hand, and said casually: "Didn't you say today that I killed you in a dream and have to compensate you?" ”

Liu Suian then remembered that he did seem to have said such a thing before leaving today.

But he was just joking at the time, who would have thought that Fang Qian would really buy it.

This man's brain circuitry is really strange.

Feeling ashamed, Liu Sui'an said unexpectedly: "This won't be the hush money you pay to watch the film in the dormitory." ”

Hearing this, Fang Qian couldn't help but feel cramped, and he didn't know what to say for a while.

He regretted that he didn't hold on this afternoon, and for the sake of momentary pleasure, he ruined his image in the eyes of his roommates.

“…… I'm guessing you saw it, dog thing. "Fang Qian didn't have a good airway.

To avoid embarrassment, he put on his headphones and continued the passionate battle in the game.

"It's a pity that I just finished dinner, so I have to eat again tomorrow."

Liu Suian said as he covered it with his body, quietly put the metal box in the deepest part of the wardrobe, and then covered it with his clothes.

After thinking about it, he took out the lock he bought at the beginning of the school but never used it, and locked the wardrobe.

Looking at the locked wardrobe, Liu Suian nodded with satisfaction.

If someone really knows Bai Ze's details and covets her, a lock of less than ten yuan can't stop anything, but the last lock at least gives him a little more security.

Do you want to buy another safe?

Liu Suian pondered.

Then he shook his head, this is too much silver three hundred taels here.

Under Liu Suian's deliberate cover-up, Fang Qian, who was focused on the game, didn't notice anything, and the other party didn't even notice the extra silver-gray earrings on his ears.

Otherwise, most of them will comment on 'You're so sassy'.

After doing all this, Liu Suian turned on the computer on the table, found some videos about alien conjectures and watched them.

Most of the video content is related to the 'Fermi paradox', which explores whether aliens exist or not, and if so, why humans have not found any trace of 'them'.

At twelve o'clock in the middle of the night, until Liu Suian went to bed after watching the video, Bai Ze didn't say anything again.

……

After the earth rotated for half a circle, Liu Suian opened his eyes again, he picked up his mobile phone and saw that it was almost eleven o'clock.

At this time, his face could not hide his tiredness, but his eyes seemed to be full of light and hope.

Lying in bed last night, Liu Sui'an's mind was full of what happened that day.

He reviewed his encounter with Bai Ze, constantly thinking about the possible truths and the changes that Bai Ze might bring to his life.

Finally suppressed these messy thoughts, and the code that had been changed today came to mind again, and the more he thought about it, the more it made sense, why didn't he think of such a change before.

In Fang Qian's snoring from time to time, Liu Suian lost sleep.

Tonight, he learned a little more about the universe, and he was eager to continue discussing her origin with Bai Ze.

At the same time, I also want to describe the taste of 'incense' for her in more detail.

But considering the sleeping Fang Qian, Liu Suian didn't speak after all.

Because of his overactive thinking, he couldn't sleep until five o'clock in the morning, until now.

After waking up, Liu Suian got up at a speed he had never had before, and then brushed his teeth and washed his face, faster than in his third year of high school.

From opening his eyes to leaving the dormitory, it took Liu Suian less than two minutes to add up, leaving Fang Qian with a confused face in the dormitory.

Eight minutes later, in the familiar laboratory building, Liu Suian rushed to Laboratory 304 at the same speed.

Pushing open the door to the lab, he saw an unprecedented scene in the lab.

I saw that in the laboratory, except for Han Qiming's absence, no one was in their seats, and they all gathered in front of the server in the corner of the laboratory, staring at the server that Liu Suian had been using.

"There's only one last training cycle left, and the accuracy is still rising!"

"Three-two! Four! Three-three! Three-five! Sanqi! ”

"The training is over, the accuracy is 87.37, Liu Suian's neural network is open."

"What kind of black technology did he use? I was still ...... when I had a group meeting last week."

Listening to the discussion of the crowd, Liu Suian couldn't wait to squeeze into the crowd and looked at the screen of the server.

"Accuracy: 87.37."

What a situation!

That's too high, isn't it?

Liu Suian's eyes widened.

On this dataset, the original Vit model achieves an accuracy of 85.72, making it the most accurate neural network model on this dataset.

However, Vit is more than a little more computationally intensive than other neural networks.

Liu's research direction is to design more efficient algorithms to reduce the computational effort of Vit models and maintain accuracy as much as possible.

However, after Liu Suian's previous 'optimization', the amount of computing went down, and the accuracy directly fell below 82.

For months, he couldn't find any workaround.

Under Bai Ze's guidance, the optimized neural network has not only greatly reduced the amount of calculations, but also increased the accuracy instead of decreasing, which is simply the explosion of the previous algorithm!

Looking at this result, Liu Suian gently stroked the silver-gray earrings on his ears with his hands, his face was as light as possible, but his trembling hands revealed the ecstasy in his heart.

It seems that I have picked up something terrible.

"No, what did you change, why is the accuracy so high all of a sudden?" A graduate student with black-rimmed glasses asked, his name is Cao Xiaohui.

"Hello? Don't talk and pretend to be a master, right, how do you do it? Why is the accuracy so ungodly all of a sudden? Seeing that Liu Sui'an didn't react for a long time, Ji Qing, another graduate student in the laboratory, stretched out his hand and shook it in front of Liu Sui'an's eyes.

Cao Xiaohui and Ji Qing, like Liu Suian, are about to usher in the mid-term defense of their graduation project, but the difference is that they have already completed the rough prototype.

Liu Suian came back to his senses and said lightly: "I didn't change anything, I just corrected a few bugs that I haven't found, and I didn't expect the result to be so good, hehehe." ”

When someone else's jaw drops, behaving inappropriately is the favorite way for most people to pretend to be forced.

Liu Suian knows this well.

"Congratulations, I'm able to graduate now."

Ji Qing patted Liu Sui'an on the shoulder, and then said slightly exaggeratedly: "No, I am still discussing graduation now, and the pattern is small." For the sake of our good relationship, when we send top conference papers, can we leave a place for my buddies to make four or five works? ”

Ji Qing is a bold Shandong man, with a height of 1.85 meters, half a head taller than Liu Suian.

He usually has a good relationship with Liu Suian, and when he saw Liu Suian's result today, he was sincerely happy for him and couldn't help but make a joke.

Knowing that Ji Qing was joking, Liu Suian's smile was no longer restrained, and responded: "Brother Ji is divided." Not to mention the position of the fourth or fifth work, even if it is the second work, if you want it, I have to ask Professor Zhang to make room for you. ”

"Rob Professor Zhang's second work, then I don't want to graduate." Ji Qing hurriedly waved his hand.

After two years of getting along, the relationship between the graduate students is very familiar, and the atmosphere in the laboratory is gradually warm.
