The next afternoon.
Shen Jiang went to the electromagnetic shielding room for adaptive training as usual. She relaxed her body and sat on the armchair. Phytolacca remotely controlled the scanner to lower slowly.
"Supervisor." She called Shangluca.
"Huh? What's wrong, leader?" Shanglu held the tablet in his hand, raised his head and responded.
"How long does it take to complete the adaptive training?"
"Based on the current situation, it should be done in one or two weeks. Adaptive training has two main purposes. One is to filter out the clutter from the electrodes in your brain, and the second is to familiarize you with the work of the MEG system. Paradigm." Phytolacca tapped his temple with his index finger, "MEG and iEEG are really different when it comes to playing, right?"
Shen Jiang nodded.
There are significant differences in signal recognition between MEG and iEEG, although they recognize the same signal in different ways - μ rhythm and β waves in the left and right brain hemispheres. Phytolacca often combines them as "μβ waves" ”, with a heavier accent, we call them “Niubi waves”. Niubi waves are very awesome because they are the basis of all brain-computer technology for limb control based on motor imagination. No matter what path you have BCI, you want to know how the brain responds to Which arm and which leg gave the order? Then you have to watch the changes in the awesome wave honestly.
This is a method that the human brain has evolved over hundreds of millions of years to control its own physical body. The brain is a driver. It has a soft carbon-based armor with a water content of more than 90%, which no one can truly use. To control it, we need to understand the language to control it. Nowadays, humans have to put another fifty-meter-high hard steel armor on the brain, and still hope that the brain can control it like the body. This is why the more advanced the giant mechanical structure is, the more similar it is. The human body and the brain's own operating system can only adapt to the human body.
"The filtering level is progressing quite smoothly so far. The operation office is doing the feature extraction and the Science City is doing the signal decoding. After the adaptive training is completed, I estimate that the basic motor imaging function can be realized." Shanglu continued, "The real difficulty is Later, if the Rabin-Shang number of 0.12 cannot be exceeded, the resolution and granularity of the MEG system will not be able to meet your requirements for complex calculations."
"How is the Rabin-Shang value calculated?"
"A very complex system of equations. You don't need to calculate this number. This is the job of our technical department." Phytolacca shrugged. "The iEEG-BCI system you are currently using can be stable at around 0.10. Every time the RS number decreases by 0.01, the sensitivity Improved by 10 times."
"Rabin and Shang are two personal names?"
"They are two names." Phytolacca replied, "They were the main pioneers of the practical use of BCI at that time. You must have heard a saying: 'BCI is a miraculous technology'. It is indeed a technological miracle. Within ten years, people Within a short period of time, a slow system with a maximum output of 60 bits per minute was developed into a super brain computer that can perform numerical relativity calculations. This process was originally estimated to take twenty years, but someone shortened it by ten years."
After saying that, he left the shielded room and closed the door behind his back.
The shielding room became quiet, and Shen Jiang waited for the execution moment.
It seems that she is not sitting on a MEG, but an electric chair.
"Let's continue today's training subjects. The old rules are that if you don't complete the task within the specified time, you need to sing a song by Wang Feng." Shanglu's voice sounded from the headphones.
"Hey, supervisor, can you stop singing?" Shen Jiang's scalp tightened.
"You've never seen training like this?"
"Never...never seen it." Shen Jiang said, "This is too inefficient."
"You don't live for efficiency, do you?" Phyllanthus asked.
Shen Jiang was stunned.
"I know you always want to save time, leader, but efficiency is not everything in training. Your brain needs to rest. No one has ever told you this before, because subconsciously they don't regard you as a human being." Phytolacca said.
"What am I if I'm not a human being?" Why did Shen Jiang feel that this boy was cursing him in a roundabout way.
"Superman, genius, monster, psychopath, cyborg, Iron Warrior, cyberpunk, Ghost in the Shell, or some other weird thing." Phytolactin said, "The public often thinks that because you are different, you are Everything you do should be a matter of course.”
"Then I have to thank you?" Shen Jiang said, "You treat me as a human being."
"No."
Shen Jiang was a little stunned: "Then what am I in your eyes?"
"One Punch Man."

"Using the time dilation formula, τ/τ=√[1-(v/c)]=1/n, the mass should be...m=m/[1-(v/c)]=nm, kinetic energy EE, the final answer is mc(n-1). This is a very simple narrow phase question. Supervisor, are you out of your depth?"
Phytolacca applauded in the operating room.
"It's amazing. Before I met you, I didn't believe that humans could have such amazing speed."
Shen Jiang is worthy of being the main pilot of Honglian. Once she adapts to the rhythm of Phytolacca, she immediately shows a reaction speed and calculation ability that are far beyond ordinary people. If ordinary people can improve their calculation level through training, then Shen Jiang is so extraordinary. His quick reactions, sharp insights and sensitivity to numbers are his innate talents. Several guys from the labor management office stared at the data on the monitor in a daze in the office. Bai Shu called Phytolacca and said that this was too scary. She is a multi-threaded parallel computing computer!
"Then let's start the next question..."
"Wait." Shen Jiang suddenly stopped him.
"What's wrong?" Shanglun asked, "What else do you have to do, leader?"
"Why should I sing if I fail? This is not fair, supervisor, we have to change the rules. If I successfully solve the problem you raised, then I have the right to ask you a question." Shen Jiang said, "You Do you agree or not?"
Shang Lu thought for a moment and nodded:
"Okay, you can ask it and I'll answer it."
"Okay, supervisor, please answer my question." The corners of Shen Jiang's mouth turned up, showing a smile like a little devil, "Describe the difference between the Fermi method coordinate system and the Riemann method coordinate system."
Phytolacca: Damn it.
"Choose a song by Wang Feng of your choice." Shen Jiang said coldly, "Please."
Shen Jiang quickly found a way to counter the kid Shangluca. She was really smart. She realized that the supervisor was a pure beginner in the fields of differential geometry and numerical relativity, and she had been immersed in it for many years, so Shangluca proposed to her. She could easily solve the simple questions she asked Phytolacca, but Phytolacca couldn't answer the Guangxiang question she asked, no matter how simple it was.
How dare he challenge himself in his professional field?
Shangluca had no choice but to sing two lines of "Empty". After listening to it, the guys from the labor office called him to say that the song was good.
Bai Shu acts as the atmosphere group responsible for screaming.
"I said supervisor, after the adaptive training is over, we can see the preliminary effects of the MEG system." Shen Jiang suggested as he was about to get off work, "Let it compare with iEEG in terms of sensitivity in motor imagery signal recognition. Let me see it." The capabilities of your system.”
"Okay." Shanglun agreed wholeheartedly.
This is not so much a comparison between MEG and iEEG, but rather a competition between the Operations Office and the Work Planning Office for the core position of the 110 workshop system. 1047 showed great enthusiasm for this. He found Mr. Ji to approve a special large It took a week to get two seven-degree-of-freedom robotic arms at the venue, and they were debugged and ready for use.
They need to comprehensively compare the control level of MEG and iEEG on the motion trajectory, movement distance, and holding strength of the robotic arm. Precision, strength, and flexibility are all indispensable. For this kind of test, 151 has some ancient but useful traditional projects-catching Pebbles, throwing darts and embroidering on orange peels.
