Noon.
At China Qiyuan.
The outside was already surrounded by layers and layers of reporters!
From the television stations, newspapers, and online media, China Qiyuan had become the center of attention and public opinion across the country. Even the Japanese and Korean countries were watching China Qiyuan's every move. After all, China was still the best Go player in all of Asia. Of the top ten Go players in the world rankings, half of them were Chinese, while the rest were made up of the Japanese and Korean players!
"Is President Dan around?"
"Is Xiang Rong 9-dan around?"
"I'm from Central TV. Can I have an interview?"
"I'm from Beijing Television. I would like to interview Changhe 9-dan!"
"If Shinji 9-dan loses, will we play?"
"May I ask if Xiang Rong 9-dan is confident of winning?"
The Qiyuan was packed to the brim!
"Please wait a moment!"
"The teachers are having a meeting!"
"Don't push, please wait a moment!"
Several staff members were busily attending to the reporters and media.
Inside.
Several dozen professional Go players were gathered there with ugly expressions on their faces. With Chen Ying's review and Xiang Rong 9-dan's and Li Yi 9-dan's explanations and analysis, everyone finally finished watching the two games between Peter and Chen Chi 9-dan. In the end, they were all shocked by Peter's "intelligence"!
Xu Han 8-dan said in surprise, "This is too exaggerated!"
"It really knows how to think!" Tian Weiwei turned pale!
Hu Liang 7-dan was in disbelief. "That's impossible!"
Li Yi 9-dan took a deep breath and said, "But those moves can only be made by a human. It's impossible for a machine to do so, so how did this AI do it? This is definitely not a simple imitation of big data! "
"Can Shinji 9-dan win?"
"I don't know!"
"Everyone is dumbfounded right now!"
"Yeah, no one knows anything about Peter!"
"We know too little about it, but it knows the other world-class Go players like the back of its hand through some of the data on the Internet and television!"
"Just how does it work?"
"How can it be so intelligent?"
Everyone was in disbelief!
In these two games, they had seen a lot of scary things. It even made them believe that this AI could really think like a human. In fact, it was even more meticulous and comprehensive than humans! This was too scary!
...
Back at home.
After lunch.
Zhang Ye gave Wu Zeqing a call.
Zhang Ye asked, "The Go world is in trouble?"
Old Wu nodded. "My dad has gone to the China Qiyuan to urgently discuss countermeasures. If Shinji 9-dan can win, then everything will be fine. But if Shinji 9-dan loses, then we'll be in deep trouble. Right now, the Qiyuan is also in the dark. Peter's data and operating model have not been announced, so no one knows what kind of machine it is. Right now, the enemy is out in the open while my dad and the others are hiding in the shadows.
Hearing that, Zhang Ye said, "If it's about this matter, I do know a little about it."
"Oh?" Old Wu said.
Zhang Ye thought for a moment and said, "How about this? I'll send you some of my understanding of this AI. It might not be correct, but it can be used as a reference."
Old Wu said, "Alright, I'll pass it on to my father."
After hanging up, Zhang Ye went online and found the match between Chen Chi 9-dan and Peter. After studying it for a very long time, he finally got a rough idea of what was going on.
His third sister pushed the door open and came in. "Hey, Brother, what are you doing?"
Zhang Ye smiled as he typed and said, "I'm writing something."
"Didn't you say that you wouldn't be working for half a month?" His eldest younger sister also came into the room.
Zhang Ye said, "Hai, I'm doing someone a favor."
…
At the China Qiyuan.
Dan Donghe was being interviewed.
Xiang Rong 9-dan had rejected the interview and was sitting there studying the match between Peter and Chen Chi 9-dan. At times, he would shake his head and frown.
On the other side.
Wu Changhe received a call.
"Daughter, I'm busy over here."
"Dad, I sent you some information. Have a look."
"What information?"
"It's something that Little Ye has compiled on Peter's operating principles."
"Him? What does he know! "
"Take a look at it first."
"Is the information reliable?"
"Have you forgotten what Little Ye does? He's a world-class mathematician. Things like computer programming are all derived from the binary system, so do you think it's reliable? In this area, he's the professional. Listening to the research of a world-class mathematician is definitely better than listening to a bunch of Go players, right? "
"Alright, I'll take a look."
After hanging up, Wu Changhe took out his cell phone and downloaded the document.
Soon after, Dan Donghe came back. Dealing with dozens of reporters and media outlets had left him very tired because he really couldn't come to a conclusion.
They gathered together again.
Wu Changhe suddenly said, "Come, everyone, take a look at this!"
"Ah?"
"What is it?"
"Teacher Changhe, what's the matter?"
Everyone looked over.
Wu Changhe said, "Someone gave me a copy of the operating principles of that P-whatever thing." He handed it to his disciple, Tian Weiwei. "Put it on the screen for everyone to see."
Tian Weiwei immediately said, "OK!"
Everyone was skeptical.
"How does it work?"
"Someone managed to analyze it?"
"Is it true?"
"Isn't this too fast?"
Dan Donghe's eyes lit up as he quickly strode over. "Brother Wu, who sent it?"
Wu Changhe curled his lips. "Don't bother about who it is. In any case, it's someone who works in mathematics."
The screen was quickly displayed!
Everyone looked over!
Xiang Rong also looked up!
PETER。
This was an artificial intelligence program for Go.
It mainly consisted of four parts:
1. Policy-Network. Given the current situation, predict and sample the next move.
2. Fast-rollout. The target is the same as 1, but under the condition that the quality of the moves is sacrificed, the speed can be 1000 times faster than 1.
3. Value-Network. Given the current situation, estimate whether the winner will be white or black.
4. Monte-Carlo-Tree-Search (MCTS). Connect these three parts together to form a complete system.
Its main operating principle was deep learning. Deep learning referred to a multi-layered artificial neural network and the method to train it. A layer of neural network would take a large number of matrix numbers as input and use a nonlinear activation method to determine the weights before producing another set of data as output. This was similar to the working mechanism of a biological neural brain. Through the appropriate number of matrices, the multi-layered organization would be linked together to form a neural network "brain" that would carry out precise and complex processing. It was just like how people identify objects and label pictures. It had two "brains", and it used the cooperation of two different neural network "brains" to improve the game of chess. These brains were multi-layered neural networks that were similar in structure to those image search engines that identified pictures. They started with multi-layered heuristic two-dimensional filters to process the positioning of the Go board, just like how a network of image classifiers would process images. After filtering, the 13 fully connected neural network layers would produce a judgment of the situation they saw. These layers could be used for classification and logical reasoning.
First brain: Move-Picker.
Second brain: Position-Evaluator.
Wait, wait, wait!
It was a 2,000-word analysis that was like a scientific research report. It was too professional!
Many of the professional Go players were dumbfounded by what they saw. They could not even understand many of the professional terms and phrases and could only rely on guessing. But they had a general understanding of what Peter was!
Xiang Rong 9-dan said in shock, "Who wrote this?"
President Dan Donghe also said, "Brother Wu, you even know such an expert? Which mathematician is it? "
"Why do you care who it is?" Wu Changhe did not understand these things anyway. "Just tell me if it's useful or not."
"Of course it's useful!" Chen Ying was the most excited of them all. Not only was she a top female Go player, she was also a straight-A student at Tsinghua University's Math Department. "This analysis is too important! It has already exposed Peter's operating model! If this is true, then this AI is definitely not as intelligent as the Americans boast. It doesn't even know how to think. It just makes people think that it does. Its core is still data processing! "
Two "brains"?
Deep learning?
They finally knew!
They finally knew the true face of Peter!
