Chapter 238

The LAN that Professor Mei planned to use for the test was soon set up.

The computer networks of four buildings within about three kilometers are connected, consisting of 12 computer rooms, more than 100 servers and 3000 computers. All servers and terminals simulate the pattern distribution of a government organ, three enterprises, a business center, two schools and a residential area, install a large number of applications and import huge data.

The professor found 3000 students from the school and asked them to sit in front of the computer for manual data import and conversion. In the first week, the whole network was connected with the Internet. The professor allowed these students to do anything on the Internet, and even did not prohibit them from climbing over the wall and peeping into the dark Internet.

Aoki followed the professor to a large office area on the second floor of the experimental building and saw about 100 computers neatly placed, like an Internet cafe. There are many young people like college students sitting in front of the computer. Some are playing games, some are talking about QQ, some are watching videos, some are browsing the web. Of course, some people have opened some strange software and don't know what they are doing.

Through the large office area, came to a small room. It's not small. The room is very spacious, but there are a few computers. Aoki counted, only nine.

"Is this the hub of the whole network?" Aoki asked.

"It can be said that it is or not." Mei Tui smiled mysteriously. "For us, this is the most important place. We can monitor all the data of the whole LAN through this place. But we can't control any computer outside, let alone the 80 servers and more than 2000 computers distributed in the other three buildings."

"Professor, can we disconnect the Internet now?" asked Mei Ziqing.

"Oh, let's play for a while! The work after the network is disconnected is not as fun as it is now," Mei said. "Are you clear about what you want to do?"

"It should be very clear. There are all the procedures in the volunteer work rules. Except that the final test process is in the sealed bag, they are not allowed to open it until the beginning," Mei Ziqing said.

"Well, very good." the professor nodded and smiled at Aoki. "Let's eat here today. The whole test process may be long."

"Why not set a time?" Aoki asked.

Metso said, "if the time is fixed, the accuracy of Turing test will be greatly reduced. Oh, by the way, do you know Turing test?"

Aoki said, "yes, it's a method for testing artificial intelligence invented by Turing, the father of computer. Separate people from machines and ask people to ask questions to machines. After multiple tests, if more than 30% of people can't determine whether the tested person is a person or a machine, then the machine passes the test and is considered to have human intelligence."

"Yes, it's that simple. But there's a big limitation, that is, time. When we set the test time, we put a hoop curse on the tester, which will make it easier for the machine to muddle through."

"Muddle through?"

"If you think so, if machines have real wisdom, will they be instinctively unwilling to let humans know? From the characteristics of human behavior, we can see that we are always willing to show off in front of the weak, and pretend to be stupid or even beg for mercy in front of the strong. Isn't this a kind of survival wisdom of higher creatures? If machines are conscious, they are no better than people At that time, we will hide ourselves and try not to let us find its wisdom. "

"That makes sense. But if there is no time limit, when are you going to end?"

"Let those children decide for themselves. When he thinks he can end the game, he will end the game. I think people will always be bored before machines, but it's hard to say if it's a machine with wisdom."

Mei Tuo's words are a little mysterious. Aoki still doesn't understand how to do Turing test for a LAN, so he just asks: "Professor, as far as I know, AI is now based on algorithms, not hardware. Turing tests machines on the surface, but essentially tests the software or programs carried by machines. You don't have any intelligent programs installed here. Who do you ask those testers to ask?"

May replied: "The hardware in this LAN alone can't support the operation of AI with deep learning ability like alphago. If it's an ordinary small program, it doesn't make any sense. Moreover, what if an alphago is installed? As you said, the test object becomes a program, but alphago doesn't need us to test. Our object is not a program, but based on A neural network based on hardware. Therefore, the program is not important, but the structure and information transmission mode are important. "

"But the Turing test always asks questions. Who do they ask?"

"There are dozens of different brands and models of our terminal computers. At least ten brands bring their own intelligent assistant software, such as Microsoft's Cortana and Apple's Siri. These are good intelligent programs that can be used to ask questions. Moreover, our rules allow testers to freely download what they think is the most intelligent software at present, and they can also download it through disk Install. Ziqing, "cried Mei," how many programs have you downloaded now? "

"There are about twenty," replied Mei Ziqing.

"So many?" the professor seemed surprised. "It seems that we can't underestimate the creativity and unyielding spirit of young people!"

Mei Ziqing said with a smile: "yes, I thought they would use the programs of big brands, because it is difficult to download more intelligent applications than Siri on the network. But their ideas are often different from ours. For example, some people think that QQ chat robot is more intelligent than Microsoft's Cortana."

"Well, that's a good thing. The more scattered it is, the more helpful it will be to our experimental results," Mei said.

"But the object of this test is still software?" Aoki doesn't understand.

May yawned and took her pipe out of her pocket.

"On the surface, it seems so, but when you understand this LAN as a wise guy, you won't think so," said the professor as he filled his pipe with cut tobacco, "You can think of it as a giant octopus. All the terminal computers here are the octopus's wrists and feet. We know that the octopus's wrists and feet have independent nerve cables, which can complete independent and simple judgment and behavior without brain instructions, and the brain only needs to issue very abstract instructions."

"Computer networks are similar to octopus. Every computer here, or every software we are going to test, has the ability to answer the tester's questions independently. However, we know the intelligence of these software. If there is no more powerful brain behind them, their answers will not be abnormal, and the test results can be imagined."

Mei Ziqing helped Mei to light a fire, and then added: "We have tested in a relatively small range before, and hundreds of people without exception think that it is machines, not people, who answer their questions. In fact, this can be expected without experiments, because these software, whether Siri or Cortana, are supported by algorithms and big data, not real artificial intelligence, and it is even more impossible when the network is disconnected There is no high wisdom. Therefore, the results of this test have long been expected. "

"What is the significance of this test?"

"Abnormal!" Mei Tao took a cigarette and said, "if the result is abnormal, can we understand that these octopus's arms and feet receive higher instructions?"
