Chapter 810 Convolutional Neural Networks
It's nearly impossible for two little girls to have nearly identical brain waves.But it does not rule out that the extremely small probability is similar.This idea just popped up in Chen Qun's mind, and he was relieved in a blink of an eye.The synchronized brain waves of Yang Yiyun and Du Ya did not last forever, and became different in the blink of an eye.

But just the two-second synchronization alone let Chen Qun know that this was definitely not an accidental phenomenon, it should be that Du Ya was mirroring Yang Yiyun's nerve operation.Then there are countless questions, how can a normal person imitate the neural activity of another person?Everything is synchronized, probably only the theory of quantum entanglement can explain it.

But even if it is the ultimate big move-"something is unresolved, quantum mechanics", it cannot be explained.Because quantum entanglement is only for two specific quanta, not one quantum can imitate any other quantum.

Well, imitation is an inevitable condition for the evolution of animals and even creatures. It can be regarded as a kind of nature, which is imprinted into genes, but humans have not been able to determine the efficacy of gene combinations, let alone find more complex non-humans. Rational thinking is active.

But at least from the comparison of this data, we can know one thing, that is, mirror syndrome, which really starts directly from neural activity. This is a pure imitation, which is not controlled by personal will, even in the single-celled organism stage, This phenomenon occurred.

Chen Qun was having unreliable daydreams in his mind when he heard Dongfang Wenxin give an order into the microphone.

"Okay, now both of you concentrate on the objects that appeared on the TV screen just now, the simpler the better!"

Following the eldest lady's voice, on the computer screen in front of Chen Qun, countless disorganized blue textures appeared on the screen, and it was almost impossible to identify what they were.But the most miraculous phenomenon happened. On the left screen, countless textures flickered, and suddenly converged into a round thing, and even a little bit of an apple could be seen.

It seems that the screens are also synchronized. As a clear image appears on one screen, the color spots on the other screen gradually become a blurred head portrait of a person, at least it can be seen that it is a man.

Miss Dongfang rolled her eyes at Chen Qun happily and asked into the microphone.

"Little Yiyun, Du Ya, tell me respectively, what are you thinking now?"

"I'm thinking of the apple on the screen."

"I'm thinking of Uncle Apple!"

The two completely different answers made everyone in the room silent for a moment, not knowing what expressions to make.If this kind of machine translation ability can achieve this step, then with the advancement of technology, it is entirely possible to realize the super illusion world in The Matrix.

In particular, it also involves the operation of the most miraculous mirror nerve.Yang Yiyun was thinking about "Apple", but Du Ya, who had no communication, had the appearance of Ouyang Yang, a little apple, in his mind.Although this mirroring is skewed, or some kind of coincidence, there is definitely some inner neural connection.

Chen Qun felt that there were too many words in his mouth that needed to be asked, and in the end he only asked the most critical question.

"Xiao Xin, how did you translate brain waves into certain patterns?"

Dongfang Wenxin smiled confidently, gave Chen Qun a straight look, and then taught these guys the basic knowledge of the computer field in a simple way.

"Don't you know that the field of artificial intelligence was divided into two genres five or sixty years ago. One is the convolutional neural network that imitates the activities of the brain cells of the human body, and has formed its own language system called sparse coding. The initial imitation principle is to represent the images generated by the simple sensory field of view of the main visual cortex VI area of ​​the human eye in a sparse arrangement, and finally establish a mathematical model and obtain a mathematical model of basis functions."

"Then in the 90s, Professor Mickison of Harvard Medical School conducted a large-scale study on the electrophysiological phenomena of primate visual cortex and cat visual cortex. The expression is carried out by using the principle of sparse coding."

"The professor's research finally showed that there are 1 million neurons in the fourth layer of the primary visual cortex V5000 area, which is equivalent to so many basis functions, and the neurons of the retina and lateral geniculate body responsible for visual perception There are only 100 million neurons, or if it is easy to understand and replace it with electronic theory, the output neurons are only 50/[-] of the entire system, which is very effective, indicating that this strategy is very feasible."

Seeing his girlfriend turned into an old expert and old professor for the first time, Chen Qun immediately raised his hands in surrender.

"Pause for a moment. I understand every word you said, but together, I find that I don't understand you at all. It seems that I went to a fake medical school. Why don't I know anything about this stuff! Well, I understand the corresponding phenomenon of neuron partitioning you mentioned, and I also understand a little mathematical principle. But combined, I don’t know anything about it.”

After Chen Qun finished speaking, he carefully searched for the content in his mind, and found that he had no such knowledge at all.Either the system has not opened enough treasure chests, and these useless scientific research skills have not been opened, or the system is broken and hidden deliberately.

Of course, Chen Qun did not dwell on this issue.Dongfang Wenxin did not continue to explain, but directly gave a summary.

"To put it simply, this system is actually the scientific research results that have been studied abroad for decades. It has been proved that it actually exists, and even a simple data algorithm has been made. It's just that the initial algorithm is too backward. It just so happens that you The idea of ​​the equation that I inadvertently tinkered with is correct, I applied it to this algorithm and found that it matches very well, so I am improving it, if it succeeds, it will be another smarter Alpha dog!"

Chen Qun thought for a while, and asked an almost idiotic question.

"You mean that the very famous Go program AlphaGo uses the convolutional neural network algorithm you mentioned?"

"The answer is correct, plus ten points. In fact, not only AlphaGo has this algorithm, but also the small broom. I plan to upgrade the small broom so that it can perform autonomous cleaning in a simulated environment. Let's see How far it can learn. Well, let’s stop talking, today’s experiment ends here. Let’s go to eat first, and come back later to continue the experiment!”

Miss Dongfang pressed the button next to her, turned on the light in the test room, and greeted the two little girls.

"When we go to Sister Qiuyue's new farmhouse for dinner, you two little guys are not allowed to eat snacks, otherwise you won't be able to eat anything."
