Liu Weiping risked his life to verify the existence of 31.4 kHz heart waves, Assanzi stored the waveform, Ishida Sogo summoned Junichi Nakamura and Tadamichi Ito to discuss this pulse wave together, everyone analyzed and analyzed it and couldn't guess, Junichi Nakamura said: "Since this is a pulse signal, no matter how God created man, it must represent a digital signal that is encoded." Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

"Maybe it's a meaningless signal? Same as a 1 Hz sharp wave. Ito Tadamichi didn't quite believe Nakamura's words.

"There's no point in arguing, I think we have to continue along Nakamoto's approach, which is to verify him." Ishida put forward a more stable idea.

"Is it the sieve method? This brainless code may be more than the number of stars in the universe. Assanzi spent a few years in Arecivo and learned a little bit of assembly language and some computer software algorithms.

"No, sooner or later, these methods will reach a dead end. In order for a computer program to flourish, it must learn to learn like the human brain in order to solve the infinite possibilities of problems. Professor Ishida's words are like a rock-shattering statement, and the greatness of a wise man lies in creating new schools of technology rather than imitation.

Only Liu Weiping seemed to be able to understand the audience, and he was in his heart, this is the concept of artificial intelligence that the teacher talked about in college, and the so-called artificial intelligence at that time was either a sieve method or a tree method, and there was a game theory, no matter what kind of algorithm was to treat the computer as a machine to complete the tasks preset by humans, the result was actually predicted, and Ishida's only sentence made Liu Weiping enlightened.

Ishida saw that no one else was reacting, and then explained, "Nowadays, computer programs are structured programming, but they will not do anything without the expected results by shortening the calculation time of the expected results." The future program must imitate our human brain, with deep learning ability, computer learning is like a child to recognize the color, tell the child that the apple is red, the banana is yellow, and then let the child see the red flag, ask him what color it is, the child said it is red, the adult will say it is right, the child will say it is yellow, the adult will say wrong, so that the training does not stop, the child can distinguish the color, the computer is the same, tell him the method and path of learning, repeatedly through the result of stimulation, the computer will evolve itself. ”

Everyone in the room couldn't speak, Professor Ishida's thinking was too advanced, and everyone couldn't imagine what the world would be like once the machine could think about it, so Junichi Nakamura asked a realistic question, "Professor, what you said is very mysterious, maybe it's true, but what does this have to do with the pulse wave that we want to figure out?" ”

"Last time I mentioned the RSA algorithm to you, its brilliance is that everyone knows the encryption algorithm, which is the truth that it is difficult to decompose the inverse operation by using the product of large prime arrays, which is a public algorithm, but even if you get the key, it is difficult to succeed in the inverse operation in a limited time, so such an encryption algorithm is difficult to crack. And the pulse wave we are facing does not know its encoding method, if it is encrypted, we do not know the encryption algorithm, and we do not have the parameters to unlock the password. If we need to crack it, our computer needs to learn like a human brain, input hypothetical parameters and constantly adjust the direction of learning according to the path of approximating the result, spiraling up, and finally finding the cracking path. Ishida also said his idea of implementation in one breath.

While everyone else was digesting, Liu Weiping seemed to understand, "This requires unimaginable computing resources!" We simply do not have such conditions. ”

Professor Ishida nodded, "An astronomical number of CPUs is required. Assanzi thought of the supercomputer for Arecivo, and he knew that it had not been updated for more than a decade, and Assanzi did not speak.

"I'm interested in the professor's learning algorithms right now, which seems to be more promising than the study of pulse waves." "With the current speed of development in Japan, Ito Trading will surpass Wal-Mart by the next year at the latest, and I will be the richest man on the planet, and I will be strong enough to support you in carrying out your plan." ”

"Supercomputers need to purchase supercomputers as quickly as possible, and then organize and write programs, and as the programs run, the computing CPUs are constantly increased, and computing resources must grow at an exponential rate to ensure that computers continue to learn like human brains." Professor Ishida took out an electronic calculator and typed it out, and Tadamadi Ito was shocked, "According to the current price estimate, maybe more than a trillion yen!" ”

"Professor, you forgot Moore's Law, every eighteen months the speed of computing doubles, the price is halved, and the cost of computing resources is exponentially reduced." Junichi Nakamura's words gave Ito Tadamichi a boost again, "Next week, I'll arrange for someone to purchase an HP minicomputer for your experiments!" ”

"Great, I've been applying to the University of Tokyo for so many years and I haven't been approved." Ishida laughed happily.

In this way, Ishida's laboratory became a computer room, and Liu Weiping got into it and never came out.

Lin Shuangmian's belly is getting bigger and bigger, obviously not suitable for attending classes, so he had to apply for a leave of absence, Ito Tadado entrusted Mrs. Ishida to help rent an apartment nearby, Assanqi came to offer hospitality when he was fine, shh

Every Monday and every month, the moon will always meet, and the frequency of Ito Tadado has increased significantly, and he has to ask about the progress every time, and Liu Weiping is very annoyed, where is there such a hurry, Ishida proposed the idea of learning algorithms, and he is really at a loss to build a model, and he can't find a breakthrough at all.

In October, Ito Tadamichi didn't come for two weeks, Professor Ishida was a little anxious, Liu Weiping came up with a verification program, just ran on the HP minicomputer for two weeks, and the computing resources were exhausted.

On Monday, October 19th, we had to meet again as agreed, and on Sunday, Ishida repeatedly called Ito Tadamichi to come over and decide to buy a new minicomputer, and Ito just coped with it on the phone.

On Monday afternoon, a few people waited until they were about to get off work, and Ito Tadamichi did not show up, so Ishida called Ito's house, but no one answered, and called the office again, and the phone was noisy, and a female voice said with a crying voice: "The president is upstairs, and he is going to jump off the building!" ”

Ishida Sogo was taken aback, and he and Liu Weiping went downstairs and drove to Ito's office.

When Ito's business was booming, he bought the building next to the Tokyo Metropolitan Police Department in Nihonbashi as an office headquarters, which belonged to Chuo Ward, and there were many financial institutions, Mitsui and Mitsubishi all gathered here.

The Asahi Shimbun even believes that his status is not under the four gods of Showa, and since Ito Tadamichi made a big purchase on the New York Stock Exchange, he actually did not pay attention to Akio Morita and Konosuke Matsushita.

Ishida Sogo got on the elevated road, drove to the Nihonbashi area and stopped, the car in the distance drove slowly, Professor Ishida was in a hurry, and finally got off the ramp and drove to the Ito Trading Building, when he arrived at the door, there was nothing empty, Nakamura Jun got out of the car and inquired only to know that Ito Tadado was not in his trading company at all, and ran to the Tokyo Stock Exchange building.

It was seven o'clock in the evening, and the road was so crowded that the four men had to get out of the car and run all the way to the exchange building, but fortunately, it was only two blocks away, and when Ishida was out of breath, they saw that the road below the exchange was full of people.

Ishida got into the front row and saw Ito Tadamichi standing on the roof of the building with a white shirt on his head and shirtless, holding a short knife in one hand and shouting, the people next to him were talking, some hid their faces and cried, and some of them were furious, and most of them were stunned and waited to see Ito cut himself.

After staying for a few minutes, Liu Weiping understood, since October, the domestic and foreign stock markets have been falling endlessly, Ito Trading's shares have been falling, and Ito Tadado's listed companies purchased in the United States are no exception, Ito Tadado in order to maintain the reputation of the trading company and the confidence of investors, with his own trading company's real estate mortgage to buy back shares in the market, after the real estate mortgage is completed, and then with the stock pledge, he even risked the world's condemnation of the long mortgage, as the stock market fell, several major banks united to collect debts, Ito Tadado had to entrust dealers to sell stocks, this stabbed the hornet's nest, the stock prices of listed companies controlled by Ito Trading Company leaked mercury, and the world's major exchanges also fell across the board, and no one dared to take over.

As soon as the market opened this morning, the Nikkei 225 index fell all the way, and by the end of the afternoon, it had a wild 600 points. Tadamadamichi Ito went to the roof of the exchange alone and threatened to make a self-determination, the police sent negotiators, and the fire department brought air mattresses in case of accidents.

Sogo Ishida snatched a loudspeaker and shouted at it, "President Ito, I'm Ishida, come down quickly, come to Japan, we've cracked the code, and we can make a comeback!" ”

I don't know if Ito Tadamichi heard it from above, but the people below heard him hoarse from above, "I am the god of management in all of Japan, the god of management that cannot be defeated, and Mitsui Bank is shameless!" Don't dare to fight outside, just come to fall into the well! ”

There was a curse below, "The god of fart management, we are bankrupt if you lose money, you are shameless!" "Scammers, never dividends, only spend our money to buy everywhere!" "I'm going up to act again, and I'm going to show the whole world and I'm embarrassed by Japan." "His cash has long been transferred to the United States, and there is a building left in the country, which is still insolvent."

A gust of wind blew these words to the roof of the building, and then Ito Tadamichi heard it, "You fools, do you know the difficulty of starting from scratch, do you know the responsibility of being in charge of 500 billion yen?" I don't have to worry about you, I will apologize to the whole of Japan. ”

"Please don't irritate him, I'm his friend, I know he's a good guy." Ishida and Nakamura were busy appeasing everyone, Liu Weiping had never seen such a scene, and he didn't know what to say.

"Good man, see that you are also his gang, do you know that we lost all our money, and we don't have a pension, look at how he apologizes." Several police officers came over and pushed the noisy people out.

"You guys send more reinforcements!" Ishida pleaded bitterly, "If he continues like this, he will really have to jump." Who knew that the police were indifferent, "there is now more than one like him in Tokyo, and there are no more cars to send corpses to the morgue!" ”

"Apologize! Apologize, apologize! A group of people shouted together, Liu Weiping felt a burst of contempt in his heart, he had just come to Japan and had a good impression of the Japanese, he felt that the Japanese were polite and polite, they bowed when they saw people, the road was clean, everyone was polite to each other, Liu Weiping even doubted how the Japanese could do such an evil deed as the Nanjing Massacre, and now when it comes to life and death, where is there any benevolence, righteousness and shame, Liu Weiping was disappointed for a while.

It was a stalemate until nine o'clock at night, several times the police wanted to go upstairs, but they were forced back by Ito Tadamichi with a short knife, Ito Tadamichi's hoarse voice gradually became smaller, Ishida urged the police to think of a way quickly, "You don't have to be impatient, according to our experience, a situation like him is psychologically compromised, wait a little longer He will find himself under the steps, don't worry." ”

I don't know who in the crowd pulled their throats from afar, "Oh no, the United States is open, the Dow is 300 points gone, straight down, straight down, you guys listen to the radio!." There was a burst of agitation below, and Liu Weiping just watched coldly.

I heard Tadamichi Ito shout from the top of the building with all his might, "I'll show you what the real god is, and watch with your eyes open!" Ishida yelled no, and by the light on the roof, he saw Ito Tadamichi's right hand with a short knife inserted into his left abdomen and pulled it to the right, and his left hand reached in and pulled out the internal organs with all his might, and threw them into the air, and the person was thrown off like a kite with a broken string.

There was silence below, only the mournful whistle of sirens, and the smell of blood in the air. Liu Weiping was stunned, and several people in the crowd actually knelt down, bowing their heads and chanting words. Sogo Ishida sat on the ground, "It's over, it's over, I won't see it in my lifetime." ”
