(Tuesday, April 23, 2013 night; apartment 4th floor, Akiyama Sora House)

Sora Akiyama is packing his luggage for a business trip. www.biquge.info According to the plan, he will leave for Tokyo tomorrow morning to attend a three-day cognitive science conference.

"Is Akiyama leaving tomorrow?" Nanamiya asked casually, observing the large drone on top of the cabinet with interest.

"Hmm. The official meeting starts the morning after tomorrow, so if you don't want to be late, you have to arrive the day in advance. Sora Akiyama folded the change of clothes and put them in the suitcase, and said without looking back, "If you want to take a closer look, you can take it down, this thing is not so delicate." ”

Tomoon Nanamiya stood on tiptoe, took off the drone, and tossed and turned around for a while. During this time, Sora Akiyama packed the clothes he was going to carry.

"Your drone doesn't seem to be the same as what you see on ordinary TV and the Internet!" Nanamiya Tomoon looked at the flight recording on his tablet, "It seems to be a little more delicate and agile, and the shooting video is much better than the average one." ”

"These are really better than the average consumer-grade model. Regardless of the body and power plant, the sensors, communication systems, and control systems are far superior to most products on the market, and the algorithms are a little more advanced. What you call motion comes from computer vision technology, where the camera collects data and sends it back to the processor for processing, so that it can achieve functions such as avoiding obstacles. Of course, in this way, due to the investment in cameras and processors, plus the expenditure of various other hardware, the cost is much more expensive than that of ordinary drones. ”

Sora Akiyama briefly explained the principle, but did not mention his lead in algorithms. In this world, it is impossible to refine a flying sword like in the previous life, but it is still possible to learn from the algorithm of flying sword control. He didn't want to expose this knowledge that was obviously too advanced.

"I see. It's a pity that it's night, otherwise I'd like to give it a try. "Seven palaces Zhiyin is leisurely fascinated.

"It's okay to fly at night. However, it's a little late, and you still have to go to school tomorrow, so let's talk about it next time you have time. The longest distance of 6 kilometers is too short to be interesting. ”

"Well, I'll go back first...... Anyway, Akiyama, you don't seem to have told me what you're studying. I've looked up the data, cognitive science is a very broad concept, and brain-computer interface is also a very broad interdisciplinary discipline. ”

Sora Akiyama thought she was going home, but she didn't expect the other party to suddenly stop and ask.

Indeed, cognitive science encompasses a wide range of topics, including philosophy, linguistics, psychology, computer science, anthropology, and neuroscience, but focuses on the study of the human mind and cognitive processes. And me...... I guess I know a little bit about it. He pondered for a moment, organizing the language in his mind, "My research is biased towards mathematics, logic, and computers, so I chose the field of brain-computer interfaces. For example, neuroscience, especially brain science, is the study of computer hardware, while psychology is the study of computer software. Hardware and software can be studied separately, but only together is a computer. ”

"Bhaha! No wonder the [Reincarnation Master] doesn't mention specific research!" Nanamiya Tomoin patted him on the shoulder with a smile, "Okay, the arcane level of this [Magic Demon King Girl] is really not good!"

Akiyama Sora was speechless for a moment. Please,Unless it's a student in the same department.,How can you talk about mathematical logic with your cute sister all day long?

Well, there don't seem to be many people who talk a lot about magic settings...... Sure enough, is the second middle school girl happy?

"Now, can you tell me a little bit more about that?"

"You're not planning to study this in the future, are you? Well, you have a lot of backgrounds in this industry, including medicine, biology, computer science, and even physics. Sora Akiyama quipped, "For example, there is a genius scholar who is engaged in quantum physics, and his research direction is quantum phenomena in the brain. ”

He and Kayaba have been in constant email communication, and his presentations at the conference included some mathematical models based on the work of the other group's research group, neural processing and quantum cognition. Not only that, but later his laboratory will also conduct joint research with the other party's research laboratory.

"Is there anyone else in Akiyama's eyes who can be called a genius?"

"Ahem...... Individual abilities are limited, and it is impossible to be proficient in all areas at the same time. Although I am a little confident, I am not so arrogant that I regard the heroes of the world as nothing. ”

Even though he is limited by the human brain and unable to transmit all his memories, Sora Akiyama still inherits the wisdom of his previous life as the [Reincarnation Master]. Even if he doesn't use [divine power], he is still a proper "reincarnation of the mighty", and he really doesn't have the idea of showing superiority in front of mortals.

Akiyama is a god, and he will not commit two to this one.

"Hahaha...... So, I'll go first. Nanamiya Tomoin waved at him, "I have a class tomorrow." ”

After the other party left, Sora Akiyama put his laptop and tablet in his backpack, and after making sure that there were no missing items, he went to bed and prepared for bed.

(Friday, April 26, 2013, afternoon; University of Tokyo)

It takes just over two hours to get from Kyoto to Tokyo on the Nozomi train. Sora Akiyama departed from the institute and arrived at Shinagawa Station in Tokyo at around 6:50 p.m. the day before yesterday and settled at the hotel he had booked. Yesterday morning, he traveled to the University of Tokyo to attend the sixth conference on "Brain and Cognitive Science".

The first day of the conference consisted of a special session and an opening lecture. Workshops run from 8:30 a.m. to 4:30 p.m., and the opening lecture begins at 5 p.m. with a presentation by Professor Natsuo Hasei of the University of Tokyo on "Nerves and Cognition: Processes in the Brain."

Today is the second day of the conference, and it is also the official start of the symposium. Since most of the workshops were held at the same time, Sora Akiyama had to choose the topics he was interested in—electroencephalography, accelerated learning programs, implantable multi-electrode arrays, and genomic brain imaging.

The symposium was divided into two parts: lectures and exchanges. The former is set up by the authorities in various fields, while the latter is a more free and casual time for communication. Each of these lectures has its own merits, and it is a slight addition to Sora Akiyama's field of knowledge. It is worth mentioning that at the exchange meeting about the accelerated learning program, he met Akihiko Kayaba, whom he had never been able to meet.

Kayaba Akihiko's appearance was more ordinary than he expected, it was a typical passer-by face, and he was wearing a featureless outfit such as a shirt, tie, and white coat. He was accompanied by a short-haired woman in a smart and simple suit.

"First meeting, Professor Akiyama. ”

"Hello, Kayaba-kun. Sora Akiyama kindly reached out and shook his hand, then looked at the woman beside him, "I don't know who this is?"

"When we first met, my name was Rinko Kamiyo. The woman offered to hold out her hand to him. Sora Akiyama gently held the front half of the other person's palm, and then closed it with a touch, and behaved very appropriately.

"Rinko is my lover and a junior in the laboratory. Akihiko Aoba explained.

After a brief introduction, the conversation quickly turned to the field of accelerated learning. "Accelerated learning" attempts to build an interactive brain-computer interface based on the measured neural and other physiological data related to task learning, and ultimately aims to improve individual learning efficiency.

"Professor Akiyama, I remember that some time ago, a company called advanced_brain_monitoring developed an adaptive and interactive set of neuro-educational technologies that supposedly could accelerate the progress of skill learning with automated reasoning based on measurements from neurophysiology. Last night, I saw that your research group published a paper on similar experiments on macaques, but unfortunately I didn't have time to read it carefully, and I have some doubts about the accelerated learning process......"

"This research was done by the PhD students in the research group, and it was combined with accelerated learning of molecular biology techniques — you know, the kind of thing that won't be able to be tested on humans for a while. This study is actually based on the work published in Neuron a few months ago by a team from MIT, Harvard, and others on the role of nascent neurons in distinguishing memories. To put it simply, the MIT team used mice as research subjects to selectively overexpress the transcription factor KLF9 to eliminate more than one-fifth of the dendritic spines of old neurons in the mouse brain, and to multiply the number of new neurons integrated into the hippocampal circuit, and then to normalize the expression of KLF9 to 'renew' their hippocampus. They concluded that the modified mice had less memory overlap and more accurate and solid memories, exhibiting more accurate memories in both middle and old age. My research group carried out a similar operation on macaques, and conducted skill learning experiments through additional mechanical limbs extended by brain-computer interfaces, and applied the accelerated learning program ......"

Sora Akiyama did not hesitate to interpret the work of the research group in detail for Akihiko Ikeba and the others. Later, the three of them talked about some brain and cognitive topics rather casually.

"Well, today's exchange meeting is almost over. Akiyama looked at the time, and then smiled slightly, "I have my report tomorrow, so I won't talk about it yet." ”

"Anyway, thank you very much. ”

"Well, goodbye two. ”

"Goodbye. ”

Sora Akiyama waved at each other and parted.

"[Connectivity Theory] proposes that the origin of intelligence is rooted in a power-of-2 permutation logic (n=2^i-1), which generates cell-integrated structures from specific to general, which can generate specific perceptions and memories, as well as universal knowledge and flexible actions. Previous studies have shown that this power-of-two-power-based displacement algorithm is widely present in the cortical and subcortical circuits of animals, and is used to process a variety of cognitive patterns, including appetite, emotion, and social information. Researchers have used this mathematical model to correctly predict the amount of neural tissue that will be activated in an animal in response to a specific stimulus. We already know that this computational logic is achieved by combining the random connection strategy in the superficial layer with the non-random organization in the deep layer in the cortex......"

"We added the quantum mechanical theory of Posner's molecular clusters to the mathematical model and designed special algorithms based on it. In our laboratory, macaques are used as experimental animals, using bifurcated intracellular nanotube silicon nanowire FETs modified by phospholipid and active silicon nanotube FETs to enter the nerve cells of the experimental subjects through intracellular endocytosis, and at the same time, non-invasive transcranial magnetic stimulation technology and flexible mesh brain electrodes injected into the macaque brain construct an interactive brain-computer interface. Before conducting formal experiments, we trained the macaques to form visual and feeding reflexes, and recorded the corresponding neural activity. In this experiment, we used holographic projection technology to stimulate macaques, and then ...... the input signals to the macaque's brain by executing the following algorithm"

"There have been experiments using transcranial magnetic stimulation techniques to stimulate the fusiform gyrus facial recognition area in human volunteers, and distorted facial recognition has been observed in the subjects. In this experiment, we observed very interesting phenomena at both the neural and physiological levels, such as in the V1 area of the visual cortex......"

Not surprisingly, as a partner to be cooperated, Professor Yoichi Yamada, the boss of Kayaba's laboratory, was also present. Sora Akiyama spoke confidently and fluently on the podium, laughing and chatting with other scholars who asked him questions from time to time.

"See you again, Professor Yamada. ”

In the exchange meeting after the special report, he and several doctoral students in his research group came to a small conference room with Yoichi Yamada and others. Yoichi Yamada, who is over fifty years old, has gray hair, but he is neatly combed, and with a well-cut suit, he looks very energetic. There are two other students in Shigemura's laboratory, named Nobuyuki Sugo and Ken Higa. The former is a young man with black-rimmed glasses, well-dressed and kind-looking, while the latter is a skinny man with rimless glasses and a T-shirt printed with anime characters.

Sora Akiyama invaded the network of the [Star Federation] while observing them. With the exception of Kiyo Kayaba, both Rinko Kamiyo and Ken Higa have some kind of connection to the spiritual network of the "Higan" project in their brains.

"This cooperation is not related to the psychological suggestion of the [Galaxy Federation]. Akiyama thought to himself, "If it weren't for that, how could you come across three such young talents so coincidentally?"

Ever since he was watching the battle between Rokuka and Shihua a year ago, he has been constantly using his ability to correct reality to fool the network system of the [Galaxy Federation], disguised as an existence like Akihiko Kayaba, and it is not surprising that this situation is in this situation. If it were not for this, the speed of scientific and technological development of mankind in the past decade would not have been so fast.

Akiyama relied on his amazing talent to devote himself to two things, and while speculating in his mind about the intentions of the [Galaxy Federation], he seemed to be seriously introducing the work of the laboratory to Yoichi Yamada and the others—since they were partners, they must have talked in more detail than the report just now, and added a lot of details. The other party was also enthusiastic to explain the relevant research situation.

Time passed imperceptibly in the academic discussions, and the meeting was satisfying for both parties. By the time Sora Akiyama returned to his apartment in Seta, Otsu City, it was already nine o'clock in the evening.
