Defend Namsan Park

The next morning, the base held a meeting.

All arrived, and the commander said in a solemn tone that there was a third-level contact at base 153 last night. According to the available information, it was judged that it was the feathered angel No. 032. The giant weapon Kui Niu and the angel died together. The base gave up the chance to escape, and finally died a heroic death. This contact caused a total of 133 deaths and 206 injuries. It was the heaviest casualty battle in the past two years.

All stood up in silence.

After the meeting, the Operations Office received an internal report, which was more detailed research and judgment information from the third-level contact of Base 153 last night. No. 032 Yu Angel came from the Qinghai-Tibet Plateau and overlooked Dujiangyan City on the Qionglai Mountains at an altitude of 4000 meters. Weapons can't catch it, and the giant Kui Niu attacks half-body, and drags it to the stratosphere with an altitude of 2000 meters with six high-altitude balloons with a radius of 47 meters and a height of [-] meters. Feather Angel, the entire battle lasted only one hour and [-] minutes. After Feather Angel died, its energy spiraled up and down in an extremely narrow vertical space, piercing the earth.

"Pierce the earth?"

"We estimate that it pierced the earth." Chen Yu sat on the edge of the bed, holding a book in his hand, "Because the afterflame it shoots upwards is 40 kilometers high, it makes no sense that it will be shorter downwards, the three-dimensional universe The matter in it is like air in front of angels, and it easily created a super deep hole that has never been reached in human history."

"Then standing here, can you see the United States?" Shanglu asked.

"If the hole doesn't collapse, yes." Chen Yu nodded.

Phytophthora spread out the materials in his hand on the bed. There are blurry black and white photos between the dense text, which were taken by drones at night. As the name suggests, Angel Feather is a distant, thin, glowing The shadow of light glows because the free-moving gas molecules in the air collide with the angel and annihilate, leaving only photons to escape. It floats on the top of the mountain like a cloud, and is as soft as a feather.

Facing such an angel with a huge scale, human beings generally take the most cautious attitude, because it is likely to be close to the P-Yang limit, and once it reaches the P-Yang limit, the angel will collapse inwards into a black hole.

It was the first time Shang Lu saw Kui Niu.

The last image of Kui Niu left in this world is only half of its body. The light beam of the spotlight looks like a dry animal skeleton. In order to reduce weight, this giant machine discarded its lower body and removed all its armor. A kilometer-long cable and a Riemann probe, after being hoisted, it is a huge jellyfish or squid.

"It's a pity." Chen Yu said in a low voice.

"You know him?" Shanglu asked.

"You mean Jian Bu?" Chen Yu said, "He was on duty at 151, and he is very nice."

"What kind of person is it?"

"Let me give you an example, and you will understand." Chen Yu covered the book on his face, "There is a large asylum in Mianzhu, which is dedicated to the elderly who lost their children in the collapse. Take care of their lives and help them with their funeral, because they both have a son named Jianbu."

Shanglu walked out of the dormitory, raised his head to look at the dark and low sky, imagining the shocking blow that fell from the sky.

"It's awesome."

he said in a low voice.

The Operation Office finally touched the legendary Rabin-Shang wall. They crowded in front of the computer screen in amazement, watching the twisted curve all the way down, and then bouncing on the value of 0.12, 60 After many tests, the closest one has been fitted to 0.12, but the next test result has risen back, as if there is really an invisible wall blocking it.At this time, it was approaching the middle and late November, and Shen Jiang had been sitting in the MEG-BCI system for more than 160 hours, doing thousands of questions. Wang Feng's songs were memorized, and the progress of the MEG-BCI system was advancing by leaps and bounds. "哐!" Hitting the south wall, the uncle Wang Xiangbing opened his eyes wide and said it was amazing, what the director said was actually true.

Li Wenxuan said, do you always think what he said is false?
Wang Xiangbing said that we should not be superstitious about authority, we must maintain the ability to think independently, and we must look at problems with a critical eye...

"Captain on the bridge!" Bai Shu yelled funnyly.

Shanglu pushed the door open and entered.

"Director, is our work effective?" Wang Xiangbing gave a thumbs up and pointed towards the computer, "It's already reached 0.12, and if we go to the next step, we will be successful."

Shanglu sat in his seat, put back all the messy folders on the table, and piled up all the experiment logs.

"When we did this in the Chengzi Institute of Science City, the reason for the final failure was that we couldn't take the last step. Do you remember that I told you about the characteristics of the MEG system? Its performance in terms of time resolution and spatial resolution Balanced, there is no big shortcoming, but the accuracy is naturally lower than the invasive iEEG system, which is determined by its structure, and it is inherently deficient.”

"That's why we have to customize single-player single-player." Bai Shu said.

"Yes, but this is not a panacea." Shang Lu said, "I have never said that a tailor-made system will definitely be able to break through the Rabin-Shang number wall. Judging from the current test results, with the experimental accuracy As it continues to improve, it still hits the same wall as previous experimental results."

"What is the essence of the Rabin-Shang value wall?" Li Wenxuan asked.

Shanglu thought for a while, and chose an easy-to-understand way of explanation.

"I can only tell you about my own understanding, which may not be correct... We all know that the MEG system is essentially guessing what the driver's brain is thinking. Since it is guessing, it is essentially a probability theory. The problem, simply put, is that the Rabin-Shang number is a surface expression of this probability."

Probability is the most common and magical thing in this world. It symbolizes a kind of unity in the dark. If there is anything to describe it, it is undoubtedly "an invisible hand". In MEG During the development of the system, the algorithm’s recognition and discrimination of human brain activity may be right or wrong, and a single test may have no track and irregularity. Once the number of tests increases, the commonality among the differences will immediately be highlighted.

The RCBI team said that the Bayesian formula is the theoretical basis supporting all AI algorithms, and it is also a powerful tool for people to infer what the black box is doing. If the Rabin-Shang number wall is described in purely mathematical language, then I'm afraid the final result is a layered Bayesian formula like a puff pastry.

"We hope to split the brain and the MEG system into pieces, cut them into the smallest neural activity units, and cut them into the most basic chip circuits. In this data space composed of the human brain and AI, let the two One-to-one correspondence between them, but obviously this is impossible. The human brain is a black box for us now, and AI is also a black box for us now, so it is better to let AI imitate the brain and let the black box learn from the black box. We cannot What you understand, AI may not be incomprehensible, this is what I told you before..."

"Build an electronic second brain." Zhang Zhong asked, "Then what should I do next? Do you want to continue with the questions?"

"We still have to do the questions." Phytophthora nodded, "But in the second stage, it has to learn some more abstract content."

"Wow, you sound so incompetent. You are the kind of incompetent parents who let their children do things they can't do themselves. If they can't break through the Rabin-Shang number wall, they expect the MEG system to break through by themselves." Shen Jiangshi Shi Ran leaned back on the chair, looking at the ceiling with both eyes, "When this AI imitates my brain to a certain extent, it will be able to guess what I am thinking very accurately, and then the Rabin-Shang number wall will break through it, right?"

When Shen Jiang said this, she had a little complacency on her face, and Shanglu's wishful thinking was clearly understood by her.

"Yes." Shang Lu sat down on the chair opposite her and put his hands on his knees, "That's what it means."

"Is it that smart?"

"No." Phytophthora shook his head, and admitted straightforwardly, "In theory, it should imitate your brain, the more comprehensive the imitation, the better, but we obviously don't have this level of technology, and the latest and most powerful transformer model can't do it. Now, on a concrete implementation level, we want it to capture the preconscious in your brain."

"subconscious?"

"No, it's not subconscious, it's preconscious." Phytophthora explained, "You know that the Rabin-Shang number is a comprehensive measure of the accuracy of the BCI system. Take the time accuracy as an example. The current MEG system can achieve Millisecond level, about 5 milliseconds, that is to say, a thought sprouts in your brain, and it can be perceived after 5 milliseconds, but iEEG can shorten this time to less than 1 millisecond, and there is a difference of 4 milliseconds. You are on the battlefield I have dealt with Angels before, and I know that 4 milliseconds is enough to turn the tide of the battle."

"Then shorten this time! Supervisor, that's what you do."

"If it was so easy to shorten, the Rabin-Shang number wall would not be called a wall." Shang Lu said, "The MEG system is head-mounted, and the iEEG is invasive, separated by such a thick brain tissue. , skull and scalp, the signal analysis speed of the former will inevitably be slower, which is determined by the mechanical structure, design form and working principle of the system, and there is no way to modify it.”

"What should I do?"

"There is a fact you must understand, leader, when you form a certain idea or have a certain idea in your mind, it is too late for it to understand."

Shen Jiang froze for a moment: "What do you mean?"

"If you compare MEG and iEEG to two runners running a race, then the starting lines of the two people are inconsistent." Phytophthora explained, "Due to a congenital defect, MEG is 20 meters behind the opponent at the start. When the starting gun is fired, It's doomed."

Shen Jiang was stunned.

"If you want the MEG system to beat the iEEG, or want to shorten the time accuracy to less than 1 millisecond..." Phytophthora continued, "then it must start before your starting gun is fired, that is to say, It must know what you will think next before you yourself!"
