You are a black technology boss, you didn't say it sooner!

It is actually not difficult to get Gu Changxi to sing again, within ten years, Miaofeng Mountain will be able to solve the problem for him.

But can Gu Changxi wait ten years?

Especially after experiencing this heavy blow, let alone ten years, maybe ten days later he will collapse.

Lou Qingyan understood that he had to find a possibility for Gu Changxi within ten days.

He took Gu Changxi back to his agent, and after returning to the company, he sat alone in the office, closing his eyes and thinking for a whole night.

By the dawn of the next day, his body was already very tired, but his thoughts were extremely clear.

At that time, the room was dim, and the curtains only opened a narrow slit in the middle of the huge floor-to-ceiling windows. The morning light shone through and scattered into colorful spots, which just fell on his face.

When he opened his eyes, he instinctively stretched out his hands to cover them, but the light still leaked in unpredictably, causing his pupils to shrink slightly.

After a while, he lowered his hand, allowing the light to fully illuminate him.

The curtains are still drawn, the room is still dark, nothing wrong.As for the light, this bundle is enough.

If you look into his eyes at this time, you will probably find a world full of radiance inside.

"Professor Dai, my small building, what's the matter, how is your old man recently, are you happy?"

"Well, that's it, don't worry about it."

Lou Qingyan returned to the company with breakfast, met the staff of the liquidation team on the way, smiled and nodded to them one by one, saying hello.

In fact, the entire liquidation team felt that Lou Qingyan was very strange.

It's not that they haven't carried out bankruptcy liquidation in the past. Most of those bankrupt companies have disappeared from the boss to the employees, leaving only one or two unlucky people to stay and assist in the work.

When it came to Jiahui, not only did the boss not run away, but the core R&D team of the entire company stayed.

In fact, they could guess that Xie Jin and the others were hiding in the conference room every day, probably engaged in some small activities.No one sees too many strange things, they don't bother to care about it.

Lou Qingyan entered the conference room, Xie Jin and others were still busy in it, some people's eye sockets were already covered with bloodshot eyes, obviously they hadn't slept all night.

This is the norm at the end of the research and development period of Internet companies.

In fact, they are not under pressure to launch this product now, and Lou Qingyan is not tough about the one-month R&D period, and even told them that if they can't hold it, it will be overdue.

But they themselves do not want to.

This group of people was absorbing knowledge crazily like a sponge, plunged into the door that Lou Qingyan opened for them, and never wanted to come out again.The joy of developing the spiritual world completely conceals the physical exhaustion, and the feeling of taking drugs is unstoppable.

Lou Qingyan tried to stop it at first, but he couldn't stop it at all, so he had to let them go, anyway, it's just an addiction these days.

"It's time to eat," he put the breakfast on the table and distributed it one by one, "Zhou Jun, Douju; Zizhen, this is yours; Li Yang, Shen Le, Wang Junyi, oh, I forgot that Gu Han doesn't eat steamed buns , Xiaoyu, you have a sandwich. Don’t knock, Lao Xie, come over to eat.”

"Wow, the boss bought the breakfast himself!"

"Damn it!" Xie Jin suddenly burst into violent cheers, "It's done!"

"What happened? The ghost tween function?!"

"Let me see, hahaha, I'm going to go, who came up with such a crazy idea, Brother Xie can really do it, I'm sorry for you!"

"Damn it, hahaha, it's poisonous..."

A group of people swarmed over.

Lou Qingyan raised his eyebrows, turned around and walked out of the conference room, the call on the headset was still on, "Professor, I really envy your group of good students, my studio is like raising a group of monkeys, one by one go to the room Jiewa."

After he walked out, there was a sudden stagnation in the meeting room, and everyone remembered: "This function seems to be mentioned by the boss!"

The door of the meeting room opened quietly, and a bunch of heads poked out from bottom to top one by one. Seeing that Lou Qingyan had walked away, they all let out a long sigh of relief.

Only Xie Jin and the only girl, Xiaoyu, were still sitting there.

Xiaoyu suddenly said to Xie Jin: "Director, thank you."

She turned her head and looked at the floor-to-ceiling windows beside her, where a golden city was reflected.

"I only know now that Beijing at four o'clock in the morning is not only heavy and tired, but also has such a bright scenery."

Lou Qingyan returned to the office and continued to ask Dai Kangshi questions, "By the way, Professor Dai, I would like to ask, do you know which brain-computer interface laboratories in our country are more reliable?"

"Oh, I'm not working on a brain-computer interface right now, I'm not so ambitious."

"I just want to see their prototypes and understand the level of sophisticated technology in this industry."

On the other end, Dai Kangshi was observing the work data of the students in the laboratory. When he heard the words and put down the data, he said in surprise: "Why do you have such an idea? The confidential prototypes of such advanced laboratories must not be allowed to be seen by outsiders. "

"I not only want to see it, but I also want to touch it, and I want to borrow it and use it." Lou Qingyan said honestly.

"..." Dai Kangshi felt that his old bones really couldn't adapt to Lou Qingyan's surprising words, "Don't scare me."

"How can I, I'm serious."

"Absolutely impossible." Professor Dai said decisively, "Let's not talk about whether it is confidential or not. Do you know how dangerous the brain-computer interface is now? You still borrow it to use it? The lab itself has only dared to go to the small one so far. The white mouse picks it up in the brain, and you borrow it to use it, whose brain do you want to pick it up?"

"You misunderstood." Lou Qingyan couldn't laugh or cry, "I'm talking about the non-invasive one."

"Ah? Oh..."

Since the breakthrough of invasive BCIs, the term non-invasive BCIs has suddenly fallen out of fashion.

Because it is an emerging technology, the academic community has not formed a unified standard. The concept of brain-computer interface is now very vague, and it is confused with neural prosthesis.Professor Dai has been studying this, and the Miaofengshan project proposal clearly covers the research direction of non-invasive brain-computer interface.

He said to Lou Qingyan: "Do you want to play with that kind of mind-reading toy? Go to Taobao and grab a lot."

"Professor, I'm serious. Can you help me get a working prototype? No, it's for me, it's for our lab. You think we'll need it sooner or later, right?"

"Xiaolou, although I don't know what you plan to do, but I have to remind you that the current brain-computer interface technology has great limitations, especially this kind of non-invasive one, which may not achieve the effect you want."

"It's okay, Professor Dai, as long as it can be done, I'll see the effect first."

Dai Kangshi was very fast, and a few days later he actually got a brain-computer interface prototype, which was the confidential result of a national laboratory at Peking University.

Fortunately, his neural prosthesis project overlaps with other people's brain-computer interface projects. He needs a prototype, and the other party also needs his research data on neural signals, so the two parties directly signed a cooperation agreement.

The principle of this non-invasive brain-computer interface is very simple, that is, to measure the user's EEG, decode and compile it, and restore the biopotential to the adult brain instructions.

Today's most cutting-edge non-invasive brain-computer interface achievement is made by a Chinese brain scientist, which can translate the language instructions of the cerebral cortex, and the accuracy rate is said to exceed 50%.

That is to say, when you keep thinking about a certain word in your brain, the brain-computer interface has a 50% probability of detecting it and outputting the correct answer.

This is still far from Lou Qingyan's request.

Compared with the level of the earth, Lou Qingyan's knowledge is too advanced, which means that he can't use his hands and feet in many fields.

Non-invasive brain-computer interface is one of the few fields that can be set foot in now.Because what needs to be overcome in this field is not the hardware difficulty, but the software.

The hardware aspect is nothing more than affecting the detection accuracy of the EEG, which has already reached the minimum decoding requirements.

But in terms of software, people on earth are simply hesitant and helpless in terms of noise reduction, filtering, interference removal, decoding, and re-encoding of EEG.

It can be said that 70% of the work in the field of non-invasive brain-computer interface is to study how to decode brain waves.

And how familiar is Lou Qingyan with brain waves?After retiring to become an omnic engineer, he studied this full-time, which was basically his old profession.

Moreover, in the interstellar society, scientists have not cared about the decoding of brain waves for a long time. What Lou Qingyan studies is the combination of man and machine, which is to convert the computer into a wave form and insert it into the human brain.

He was a little worried about the accuracy of the prototype machine to draw the EEG, but he was relieved after seeing the real thing.

It's tough, but it's enough.

Three days later, he brought Gu Changxi back to Miaofeng Mountain.

Gu Changxi was still silent, but the deep tiredness on his body was almost contagious to Lou Qingyan.

He ran out secretly and didn't tell the manager or anyone... Strange to say, he didn't know why Lou Qingyan asked him to come out.He deliberately refused, after all, the two were not familiar with each other at all, but every time he opened his mouth, the words Lou Qingyan said that day flooded into his ears uncontrollably like sea water pouring in.

"Its most romantic and magnificent appearance is that it can dismantle all irresistible external forces, and put your dreams squarely in front of you, so that you can walk through it step by step only by relying on your own efforts..."

Even if it was only because of the trembling feeling in his body at that moment, Gu Changxi still came.

Lou Qingyan got out of the car, saw him standing there in a daze, not knowing what he was thinking, and greeted him, "Brother Gu, come here."

The two walked into the empty laboratory one after the other.

In front of the laboratory is a huge projector screen. In the middle is a machine with wires wrapped up and down and exposed circuit boards of various colors. On the chair next to the machine is a huge helmet that is also wrapped with wires.

Lou Qingyan asked him to sit on the chair and put on the helmet for him, only to hear a slight "di--", the green light on the circuit board turned on, and several inexplicable pictures were slowly drawn on the projector screen. Waveform diagram.

Lou Qingyan explained while operating: "This device is called an external brain-computer interface, which can read your brain waves. Of course, with this kind of rough technology, it is impossible to directly read your thoughts, even if they are only vague ideas. It's also very difficult."

"Because this kind of specific thoughts and ideas contain too little content, the area of ​​neuron activity is too small, and it is difficult to detect accurately with the highest density capillary electrodes."

"Of course, I didn't call you to waste time. Guess what else this device can do?"

Gu Changxi shook his head.

Lou Qingyan said: "The mobilization of an idea, the generation of an idea, only uses a small part of the brain, and the changes in biopotential shown are very subtle. However, the existing external brain-computer interface is better at detecting brain waves. the big picture, not the details."

"You know this kind of brainwave macroscopic manifestation, what exactly is it?"

Gu Changxi thought about it cooperatively, but was suddenly taken aback.

The real-time EEG on the big screen suddenly showed obvious fluctuations.

"Emotions, beliefs, and even souls... you can call them whatever you want. In short, they are those things, which are the general trend of human brain consciousness." Lou Qingyan smiled, "It seems that you guessed it."

As he spoke, he pulled the keyboard and typed a few times, the real-time EEG on the screen froze for a short time, and then output a series of data on the left.

"Did you see this? This is a threshold summed up through complex function calculations. Generally speaking, when the macroscopic manifestation of brain waves is within this threshold, we think you are in a 'surprised' state."

The next moment, the waveform vibrated again, and Lou Qingyan intercepted the data again, saying: "It's a little bit off the upper limit of the threshold, and there is also a phase shift. At this time, it can be considered that your emotions have left the category of 'surprise' and entered The 'shocked' state. Next to this offset, it can be used to calculate other emotions attached."

Gu Changxi couldn't help but stare.

"This is the external brain-computer interface technology. All over the world are studying its application and inventing countless expensive junk toys for it. In fact, at this stage, its most mature application direction is not to interpret thoughts, but to interpret emotions. "

When it comes to invasive or non-invasive brain-computer interfaces, quite a few people would think that the difference between them is that one is implanted in the human body and the other is not.

In fact, the most fundamental difference is that: invasive brain-computer interfaces are localized and precise; non-invasive brain-computer interfaces are holistic and macroscopic.

In the early stage of technology research and development, none of them can escape from their own limitations, so they will differentiate into different functional directions.In the later stage, one by one technical difficulties are overcome, intrusive can also be macroscopic, and non-invasive can also be precise. At that time, what distinguishes them is whether they are implanted or not, and they will thus enter two cross-parallel fields. The former Human-computer integration, and the latter human-computer interaction—although there is no difference now, in the interstellar era, human-computer integration and human-computer interaction are completely two concepts.

When Gu Changxi heard the concept of interpreting emotions, he immediately understood something.

Lou Qingyan asked him to type on the notebook, and he typed: "Can you read the emotion when singing, so as to further modify the synthesized music???"

The three question marks showed how strong his mood was.

Lou Qingyan paused, and said, "Theoretically, that's the case."

"Theory? So is it not possible in practice?"

"Brother Gu, here is a rule of programming. I don't know if you can understand it, so I will try to explain it." Lou Qingyan said, "It's called the unconditional principle of emotion."

"...?"

"Meaning, sentiment-related functions can't appear in a conditional statement. Neither can a conditional for a loop. If it's used for an assignment, the value can't go in a conditional statement either."

"In other words, in computer programming, the sentiment function can only do pure mathematical calculations and nothing else."

"This is a very simple logic problem. We extract a person's emotional data x at a certain moment, and we know that the threshold of 'sadness' is ab, then we can write a conditional statement. If x is greater than a and less than b, use to show that x is in a sad mood... but after that?"

"Assuming that x is singing and he satisfies this conditional statement, then does the next line jump to roaring singing, or jumping to faint singing? Is it singing a transposition, or singing a breathy voice? It sounds like all of these can be expressed Sad, isn't it?"

"It's not that there are other ways. For example, we introduce artificial intelligence, first record x's singing habits as data, and use these data to train machine learning algorithms. In this way, a computer program that has an insight into x's singing habits can automatically choose to sing with a roar. , or sing quietly..."

"Going one step further, introduce natural language processing technology to train the program to understand human language. In this way, in addition to emotional parameters and singing habits, the program can also use the semantics of the lyrics as a reference to choose singing methods more intelligently..."

Gu Changxi originally had a glimmer of hope, but as he listened, he clenched his fists tighter and tighter...

Lou Qingyan stopped suddenly, paused, and changed his tone.

"Brother Gu, I'm not telling you this to hurt you. In fact, I want to tell you... well, all of the above are achievable."

"The principle of unconditional emotion is just a conventional concept and does not have to be followed. If we combine the four major technologies of speech synthesis software, emotional data, machine learning, and natural language processing, we can create a virtual singer that is not inferior to a real person. "

"This singer has your voice, your emotions, your singing style, and a basic human understanding of Chinese semantics."

"So, is this singing voice what you want?"

Gu Changxi lifted off the helmet full of wires and stood up abruptly.

The electroencephalogram on the big screen trembled violently for a long time, and at this moment it returned to nothingness.

From Lou Qingyan's words, he finally understood how absurd and ridiculous he had been all along.

He wanted to sing, just to sing—the very thing of singing.

Not re-voiced, not synthesized music, not some virtual singer who could replace himself.

Not to mention the vanity of indulging in the past!

He shouldn't have found vocalcords in the first place, shouldn't have come here.Years of obsession have twisted him, trapped him in a narrow cage, and he has only now been freed.

He tore off the messy wires on his body, silently thanked Lou Qingyan, turned his head and left.

Lou Qingyan leaned against the table with folded arms, and said to his back: "If this is not what you want, come and hear about the second option."

Gu Changxi froze.

"This second choice, let me say it first, is very, very difficult. Not only does it require your all-out efforts and mine, but it also requires a little miracle."

Lou Qingyan pulled over a whiteboard, regardless of whether he could understand or not, he started explaining on his own.

"The principle of unconditional emotion was proposed because people found that if emotional data is involved in a series of programming, as long as the algorithm is constant and the other conditions are the same, if the same emotional parameter is input, only a fixed value will always be output."

"But is it like this in reality? Isn't the greatest charm of emotion lies in its endless possibilities?"

"When I am in pain and depression, I may force a smile to say hello to everyone, or I may hide alone and lick my wounds. Both of them are powerful emotional expressions. Even if all other conditions are the same, I may make different choices , because in essence, this world conforms to the principle of quantum uncertainty, and my choice is random."

"We extract human emotions from brain waves, let it participate in computer calculations, and hope to obtain another emotional data, but in the process, emotions collapse."

"It collapsed from endless possibilities into an eternally fixed, cold number."

This is a paradox.

"When emotional data is involved in computer programming, it can never output a value that can represent emotion."

This is because the process of obtaining a fixed solution according to a fixed algorithm is itself anti-emotional.

In the history of the interstellar era, when scientists achieved a breakthrough in strong artificial intelligence and began to study how to give artificial intelligence emotions, this paradox was discovered.

It was only later that the "emotional unconditional principle" established in the computer field gradually came into being.

Scientists have also gradually acquiesced that the phenomenon of "artificial intelligence emotional awakening" in science fiction will not happen, because according to the paradox, robots cannot have emotions.

Until later, the emergence of quantum uncertainty algorithm overturned this paradox.
