"Hey, what's wrong? You look like an old-style CRT TV with a broken antenna. The picture is covered with noise from time to time. Do you want to go into the factory for repair? I strongly recommend to cast it again and come back directly if you have the chance.
Earth."
The one who spoke was, of course, the fat one. Lin said angrily: "I'm already very ill, so can't I say something nice and use better metaphors?"
"Well, the analog knob doesn't work very well. How do you adjust it? The radio broadcast can't adjust the channel correctly?"
...It seems that I have pushed myself too hard, Lin thought. Ignoring the fat man, Lin asked: "Did I do anything when I came down before?"
The second incarnation said calmly: "It seems that you have really forgotten something."
"I forgot something?" Lin repeated, of course he was curious and confused about the content of the conversation, and said: "You told me and I forgot, which means you still remember those things. Aren't we the same person? Why are there things?
It's something that only you know, but I don't know. It's just like you are here to kill the invading nightmare creatures. If I hadn't happened to come in and meet you, I wouldn't have known about these things."
"We are your subconscious. Some unimportant things, some things that should not be remembered, no matter good or bad, you forget, and we still know that this is a normal thing. Otherwise,-"
The fat house avatar grabbed the middle avatar and said, "──Do you want to recall what dark history you left behind in this era?"
"No, I was wrong, please forgive me. Just forget about such a topic.──" Someone immediately withered, and don't think about things that should be forgotten, "──I just want to know what I did before...
..." Before he could finish his words, new decorations on the magic tower on the second floor caught Lin's attention.
What is the content and purpose of those patterns? For Lin, who has been pondering this aspect of craftsmanship for a long time, it is not clear at a glance, but after a little thought, he almost understands its function. So Lin soon understood this quilt
What is the purpose of the magic circle that I carved on the second floor?
"This is...principal component analysis method?" After understanding what he had done, Lin remembered most of the causes and consequences. He walked around the magic tower and confirmed the programmed logic.
Understand that what is done is not complete.
This is not to say that the program of principal component analysis is incomplete. In the field of data analysis, whether it is an algorithm or other tool, there is only the most suitable, not the best. In other words, each method has its applicable conditions.
Therefore, if you want to reach a certain level in such a field, you cannot conquer the world with one move. Mastering the cross-application of multiple methods is the last word.
That is to say, the program on the second floor is only usable, and has not yet reached the level of completeness, let alone the impossible level of perfection. Wherever the program can be perfect, it is to find bugs, update them, find new bugs, update them again, and then
Once enough updates have been accumulated, the version will be revised. If updates and revisions are stopped, either the maintenance company has gone bankrupt, or new ones have been released and the old ones have been released.
So the follow-up road is still very long. But Lin doesn't want to start work now, because she is really not in good health. Besides, there is someone outside waiting for an answer. If she is kept waiting for too long, it is hard to predict what will happen.
But before he left, he saw a part of the program code that was quite strange. It was not part of the pca (principal component analysis) program, and it seemed to have nothing to do with the logic of automatic loops and automatic updates. It seemed like a redundant section.
Useless program code. This is not a test program code, used to check whether the program output is correct.
I couldn't figure out how this program could help this large section of mathematical logic, or even cause misjudgments. So Lin deleted this large piece of program code with a wave of his hand. The first step to streamline and optimize is
You dare to delete things, don't you? After doing all this, I felt much refreshed, and then I left the dreamland.
Seeing the original body leaving, the incarnation of Fat Mansion clicked his tongue. He was quite dissatisfied that the mod he had worked so hard to complete was deleted like this. The junior high school student himself said: "It seems that even if it is not stated clearly, it has been subconsciously
He also has an intuitive reaction to things we know.”
"God damn you for not being considerate of people's hearts. You deserve to be punished for the rest of your life."
"This is your self-destruction technique. The original person was raised outside and belonged to Sister Yu. Yan Ran is a victorious group in life who left Africa and joined the European Union. To be honest, we can only stay in the dream.
, unless we get gay. But if you dare to have such disgusting fucking thoughts, I will insert this unfinished magic tower into your anus."
"Hey, this seems to be quite interesting. Come and try it?"
Giving the fat man a look of disdain, the uniformed junior high school student gradually disappeared into the space. The fat man was left alone and clicked his tongue again, saying, "I am really boring as a junior high school student."
In the real world, he looked at the flames of the campfire swaying with his open eyes. After a while, Lin Wushen's eyes focused again.
Sensing that someone had returned from the dream, Fen asked: "How is it? Do you have an answer?"
"Yeah." Lin nodded, and after sorting out his thoughts, he told his thoughts and what he had done. Fen was very surprised by his answer. "Starting from mathematics, I have never thought of something like this.
method."
"This is not surprising. In a puzzle without mathematics, no one is accustomed to using it as a solution. But in fact, the ultimate explanation method for everything in the world lies in mathematics. If there is something that cannot be explained, just prove it.
There are places or phenomena that we haven’t observed yet.”
"Then there are higher-dimensional creatures."
"Yes. Explaining those existences from this perspective can also explain why they cannot move freely in the world on this side. Because high-dimensional creatures want to move in the three-dimensional world, they must reduce the dimension or rely on projection.─"
Take humans living in a three-dimensional space as an example. If they want to become two-dimensional, they can draw themselves into a painting, a comic, or even an animation. These are all methods of projection.
As for reducing oneself to a second dimension, it is either a ghost style, like a ghost in a painting; or it is a science fiction style, turning one's consciousness and memory into an existence similar to a computer virus, living between the screen and the Internet
.And these are not things that can be easily accomplished, they only exist in fantasy.
"─No matter which method, there are difficulties and shortcomings. Secondly, how the information they provide will be understood by humans, which is related to everyone's subjective cognition, that is, belief. And when the subjectivity has
If they are filled with emotions such as fear and evil, their appearance will also be terrifying and evil."
"So use mathematical methods to reduce their dimensions." Fen added, but hesitantly.
"It's not accurate to say that. It should be said that we use mathematical methods to reduce the dimensionality of the information they provide and convert it into a form that we can understand. It's not that we can't reduce the dimensionality of them. In the past practice
, people use the form of belief or learning relevant knowledge to try to get close to and understand them. But this involves too much beautification or vilification of subjective consciousness rather than reality. Dimensionality reduction using mathematical methods is an attempt to extract information from a lot of information.
, find important information, merge similar information or selectively delete it, and finally leave a 'most appropriate' explanation method, which is then understood by us. This seems to eliminate the influence of subjective consciousness, and may be more
It’s close to the real appearance, but in fact what you see in the end is still not the most original one. And different methods and different parameters will bring different results.”
"So no matter which method is used, it is not our truth. It can only be said to be a perception that is close to the truth to some extent."
"Yes. That's accurate enough. But most people can only use the former method to try to understand. The latter method must rely on auxiliary means to achieve it. And I rely on magic in dreams.
Only with the computing power of the tower can I see the world after my dimensionality reduction. But what I can’t understand is why I not only seem to see it, but also seem to be able to walk in it.”
Even though she was a genius from a thousand years ago, it took Fen a long time to digest what Lin said. Compared with what she knew and what she had experienced, none of them could overturn what Lin said.
The content even continuously confirmed the correctness of those words.
Mortal people's understanding of gods is just that elusive. Everyone has their own set of explanations, and those mortals who serve gods also have their own set of understandings, and I, who have killed gods, have even touched that one.
People who are at the threshold have a deeper understanding.
As long as you cross that small gap, your life experience may be completely different. You may be among the evil gods, and you will have to fight against kindness throughout your life until you die.
But the world he could see after taking that step was not attractive to him. In other words, after the flames of revenge burned him out, all that was left was a muddy and empty shell. Until today, there was nothing like it again.
The feeling of being alive. Is it because I discovered a new world and gained knowledge about the new world? Or is it because...
"Cognition." As if to prevent herself from admitting something meaningless, Fen shifted her focus. She explained Lin's problem from her perspective. "I once said that magic is to use power to command, change the status quo or
It's about changing your cognition. The light object magic experiment I did with you is a kind of magic that changes your cognition."
It was a very interesting experiment that was done at the Tower of the Great Sage. The experimental material was a very heavy money box, a wooden box filled with precious metal coins. It was difficult for even a strong man to lift it easily.
In front of Lin and Kaya, Fen cast an apprentice-level magic light object spell. As expected of a lich, Kaya, who was very thin at the time, easily picked up the cash box.
Then Halumi, who was not present, was asked to come in, explaining that the money box had been cast with the light object spell. However, no matter how hard the blonde girl tried, she could not move the money box at all because it was too heavy.
The more interesting thing is that from beginning to end, the weight of the cash box was measured using standard methods. Before and after using the light object magic, the weight has always remained unchanged. What has changed is only 'human perception'. And this
Changes have brought completely different results.
