Xueba's Sea of ​​Stars

Chapter 288 Zero
After a highly publicized human-machine battle, AlphaGo became famous. Although it is not a household name, many more people know its name.

However, before defeating Lee Sedol, the first-generation AlphaGo Fan swept the European Go champion with a 5-0 record, so it appeared on the cover of the international academic journal "Nature".

However, Google is obviously not satisfied with this. It didn't take long for the man-machine war that caused heated discussions in the world to take place.

The second generation of AlphaGo, Lee made his debut and defeated the professional nine-dan Go player Lee Sedol with a score of 4:1, becoming the first artificial intelligence in the world to defeat the Go world champion.

Lien Chan Lian Jie, already on top of Google, quietly threw their third-generation AlphaGo and Master on the Internet. In just a few weeks, they created a record of 60 consecutive rounds of victory, and these 60 players are all from China, Japan and South Korea. The top players in the game even include Ke Jie, the number one chess player in Huaguo.

This time, AlphaGo has completely gained enough attention, and has become the number one star in artificial intelligence, and has once again aroused remarks such as "Is artificial intelligence about to wipe out human beings and occupy the earth?"

So is the intelligence of AlphaGo really so powerful?

No, in fact, in the eyes of experts in artificial intelligence, the three generations of "Fan, Lee, and Master" can sweep the Go world not because of "intelligence", but because of massive data.

Because they will learn all-round from the opponent's chess game before the game, so that when the opponent makes any move in the game, they will be listed with all the possibilities of the next step, and then push back step by step , and finally select the hand with the highest winning rate.

To put it simply, AlphaGo doesn’t even understand the rules of Go. It can only fight prepared battles. If it is allowed to play on the spot, it may not even win an amateur chess player.

How can we talk about the word "smart"?
Recently, because of experiments, papers and a bunch of trifles, Wu Bin has indeed reduced the time spent browsing the official websites of major scientific research magazines every day, so he asked curiously: "Zero... What new tricks has Google played?"

Gu Ningshan thought for a while, and replied: "It should be said that it is a big step towards true intelligence."

"Have you started to focus on this part?"

Gu Ningzhe first glanced at Wu Bin in surprise, then nodded and said: "Yes, the biggest feature of Zero is that it can learn Go from a blank state, and it can still quickly learn Go by itself without any human input. "

"Oh? That's interesting." Wu Bin nodded, showing interest.

Seeing Wu Bin's glowing eyes, Gu Ningshan snickered at first, and then said: "This time Zero should be considered to have learned the rules of Go by himself, and the AI ​​has gradually started to adjust the parameters from the games he lost or won. Later, it changed from using data streams to brute force the opponent's chess moves to choosing those moves that are conducive to winning the game."

Wu Bin: "How effective is it?"

"That's amazing. After only three days of self-study, Zero rubbed the second-generation Lee on the ground with an absolute score of 100 to 0. After another 40 days, the third-generation Master also became his dead ghost. "

"It's interesting, if you don't bully humans, start playing civil war..."

After the Master brutally abused almost all human elite chess players, Google immediately announced that it would no longer participate in any chess games between humans and machines. It is typical to run after pretending to be B.

Chatting and chatting, the two had arrived at the Golden Arch. As usual, Wu Bin ordered a Big Mac set meal for Gu Ningshan. At first, the girl said that the Big Mac was so big, how could she possibly be able to eat it, but then Facts have proved that one is not enough for her to eat!
"Would you like another box of chicken nuggets?" Wu Bin turned to ask Gu Ningshan.

"A hamburger is enough for me." Gu Ningshan shook her head.

"That's fine, I'll eat it myself."

After ordering, the two took the plate and found a place to sit down. Wu Bin picked it up and took a sip before asking, "What do you think after seeing this Zero?"

"How should I say it~" Gu Ningshan tore open the ketchup while thinking, "I think a single algorithm that can solve multiple complex problems is the first and most important step in creating a machine learning system to solve practical problems .”

"Hey~ It's very profound. It seems that you have learned well recently." Wu Bin praised with a smile, "By the way, what do you think of the professors in the Faculty of Letters?"

Although the University of Science and Technology already has the idea of ​​establishing a college of artificial intelligence, it has not been implemented, so artificial intelligence is still classified as automation and computer-related majors.

Gu Ningshan, who has a strong interest in artificial intelligence, is also very resolute, and was transferred to the information technology department in minutes. From the current point of view, she should be very satisfied with her choice.

"Very powerful." Gu Ningshan nodded, "Oh, by the way, Professor Zhang will give a lecture in the water lecture hall next week. You should be interested in listening."

"Which Zhang... um!? Could it be Professor Zhang Yaqin?" Wu Bin exclaimed.

When Wu Bin was still in the national team, Song Nanfeng mentioned Zhang Yaqin to him several times.

Entered the junior class at the age of 12, the first full-score Ph.D. in the history of George Washington University, and the former president of Baidu.

Picking up a piece of French fries, Gu Ningshan replied, "Otherwise it could be Professor Zhang."

Wu Bin took a bite of the hamburger and asked vaguely, "What kind of lecture?"

"It seems to be about artificial intelligence and autonomous driving."

"Is he still doing scientific research?" Wu Bin was a little surprised.

Zhang Yaqin has a total of more than 60 US patents, which is completely lying on the golden mountain, and he has kept a low profile after resigning from Baidu's president, so Wu Bin thought he had already enjoyed his life.

"I don't know whether to do scientific research or not. Anyway, I will know after listening. If you want to come, I can reserve a place for you."

"Okay~ Comrade Xiao Gu, you have quite a lot of power."

"That's not true~" Gu Ningshan took a sip of Coke proudly.

"Okay, put away your little tail and talk about the topic just now. I think the appearance of ZERO means that Google has begun to stop rushing to win and start to pay attention to learning."

"This is the concept. This time they used 5000 TPUs on ZERO, combined with deep neural networks, enhanced learning algorithms and general tree search. Now I am very curious about where they plan to use this technology next. "

"Yeah~ I'm curious too..." Wu Bin chewed a burger and began to meditate.

PS: I don't know how to describe the four days... I have experienced a thrilling life adventure, and now the adventure is back, anyway, I have started to update it!
