"Hey, what's wrong? You're like an old-style picture tube TV with a broken wire. 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. If you have the opportunity, go back directly. Earth."
The one who spoke was, of course, the fat one. Lin said angrily: "I'm already very ill, can't I be more obedient and use better metaphors?"
"Well, the analog knob doesn't work very well. How do you adjust it? The radio broadcast can't even adjust the channel?"
...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 you have really forgotten something."
"I forgot some things?" Lin repeated, of course he was also curious and confused about the content of the conversation: "You said I forgot, that is, you still remember those things. Aren't we the same person? Why are there things that only happen You know it, but I don’t know it. It’s 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 speaking, new decorations on the magic tower on the second floor caught Lin's attention.
What is the content and purpose of those patterns? Although it is not clear to Lin Lai, who has been pondering this aspect of craftsmanship for a long time, after thinking about it for a while, he can almost understand its function. So Lin quickly understood what the magic circle carved on the second floor was used for.
"Is this... principal component analysis method?" After understanding what he had done, Lin remembered most of the causes and consequences. After walking around the magic tower to confirm the programmed logic, I also learned that the completed part was not complete.
This is not because the PCA procedure is incomplete. In the field of data analysis, whether it is algorithms or other tools, there is only the most suitable, not the best. That is to say, each method has its applicable conditions. Therefore, if you want to reach a certain level in such a field, you cannot do it all in one move. Mastering the cross-application of multiple methods is the last word.
In other words, the programs on the second floor are only usable and have not yet reached a complete level, let alone an impossible level of perfection. Wherever a program can be perfect, the only way is to find bugs, update it, find new bugs, update it again, and then revise it after accumulating enough updates. Those who stopped updating and revising the software were either because the maintenance company went bankrupt, or they released new ones and released the old ones.
So the road ahead is still long. However, Lin didn't want to start working now because his physical condition was really not good. There is another hot answer outside. If she is made to wait 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 is not part of the PCA (Principal Component Analysis) program, and it seems to have nothing to do with the logic of automatic looping and automatic updating. It looks like a redundant and useless program code. This is not the part of the test program code used to check whether the program output is correct.
He couldn't figure out how this program could help this large section of mathematical logic, and it might even cause errors, so Lin deleted this large section of program code with a wave of his hand. The first step to streamline and optimize is to dare to delete things, right? 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. I am quite dissatisfied that the MOD I have worked so hard to complete has been deleted like this. The junior high school student himself said: "It seems that even if it is not stated clearly, he will have an intuitive reaction to things that are already known to us subconsciously."
"The guy who kills dogs and doesn't know how to care about people deserves to be punished for the rest of his life."
"This is your self-destruction technique. The original body was cultivated outside and belonged to Sister Yu. Yan Ran is a victorious group in life who left Africa and joined the European Union. To Lu, the two of us can only stay in the dream. Unless we get gay. But if you even think that fucking disgusting thing, I'm going to shove this unfinished magic tower up your ass."
"Hey, this seems interesting. Come and try?"
Giving the fat man a look of disdain, the uniformed junior high school student gradually disappeared into the space. Zheng Duliu, the fat man, clicked his tongue again, "I'm so boring as a junior high school student."
In the real world, I watched the flames of the campfire swaying with my 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 listed his thoughts and what he had done. Fin was surprised by his answer. "Mathematically speaking, I never thought of such an approach."
"It's not surprising. In a world without mathematics, no one would be 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 an explanation, it will only prove it. There are places or phenomena that we haven’t observed yet.”
"Then there are higher-dimensional creatures."
"Yes. To explain 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 you want to become a two-dimensional person, you can draw yourself into a painting, a comic, or even an animation. These are all methods of projection.
As for reducing one's dimension to a second dimension, it's either a wandering spirit, like the ghosts inhabiting a painting; or it's 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 done easily. 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 it is subjective Already occupied by emotions such as fear and evil, the appearance they present will also be terrifying and evil."
"So use mathematical methods to reduce their dimensions." Fen added, but hesitantly.
"This is not accurate. We should use mathematical methods to reduce the dimensionality of the information they provide and convert it into a form that we can understand. It is not about reducing their dimensionality. We cannot do this. In the past practice , people use the form of belief or learning related 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 from many In intelligence, important information is found, similar information is merged or selectively deleted, and finally a 'most appropriate' explanation is left, which is then understood by us. This seems to eliminate the influence of subjective consciousness, and perhaps it can It’s closer to the real appearance, but in fact what you see in the end is still not the original Him. And different methods and different parameters will bring different results.”
"So no matter which method is used, it is not their truth. It can only be a certain degree of knowledge that is close to the truth."
"Yes. This is accurate enough. However, 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 relied on the magic tower in the dream Only with my computing power can I see the world after my dimension 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 Fen, a genius from a thousand years ago, spent a long time digesting what Lin Chu had said. Compared with what she knew possible, and everything she had experienced, none of her experiences were enough to overturn what Lin said, and they even continued to confirm the correctness of those words.
Mortal people's understanding of gods is just that elusive. Everyone has their own set of explanations, and the mortals who serve the gods also have their own set of understandings. As someone who has killed gods and even touched that threshold, I have a deeper understanding.
As long as you cross that gap, your life experiences may be completely different. He is probably among the evil gods and will have to fight against goodness throughout his life until his death.
But the world you can see after taking that step doesn't appeal to you. Or after the flame of revenge burns him out, all that is left is an empty shell of confusion. It's only now that I feel like I'm alive again. It's because I discovered a new world and gained knowledge about the new world. Or because...
"Cognition." As if to prevent himself from admitting something meaningless, Fen shifted his focus. Explain Qi Lin's problem from her perspective. "I have said that magic is to use power to command, change the status quo or change cognition. The light object magic experiment I did with you is a kind of magic that changes cognition."
That was a very interesting experiment done at the Tower of the Great Sage. The experimental material was a very heavy money box, a wooden box filled with precious metal currencies. 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 magic. As befits a lich-level strength, Kaya, who was very thin at the time, easily picked up the money box.
Then let Harumi, who was not present, come in and find out that the light object spell has been cast on the money box. However, no matter how hard the blonde girl tried, she just couldn't move the cash box 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. The weight remained unchanged before and after using the light object magic. What has changed is just 'cognition'. And such changes brought completely different results.
