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 record of 5-0, and therefore appeared on the cover of the international academic journal "Nature". At that time, it had already caused quite a stir in the artificial intelligence circle.

However, Google was obviously not satisfied with this. It didn't take long before the man-machine war that aroused heated discussion in the world was staged.

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

After a series of consecutive battles, Google quietly threw their third-generation AlphaGo and Master onto the Internet. In just a few weeks, they created a record of 60 consecutive wins, and all of these 60 players were Chinese, Japanese, and Korean. The top players even include the number one chess player in China, Ke Jie.

At this time, AlphaGo has completely attracted enough attention and has become the number one star in artificial intelligence. It has once again caused comments such as "Is artificial intelligence about to eliminate humans and occupy the earth?"

So is AlphaGo’s intelligence really so powerful?

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

Because they will conduct comprehensive learning from the opponent's chess game before the game, so that when the opponent makes any move in the chess game, they will list all the possibilities for the next step, and then push forward step by step. , and finally choose the hand with the highest winning rate.

To put it simply, Alpha Dog actually 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 be able to win against an amateur player.

How can we talk about the word "intelligence"?

Recently, due to experiments, papers and a lot of trivial matters, Wu Bin's time to visit the official websites of major scientific research magazines has indeed been reduced a lot every day, so he asked curiously: "Zero... What new tricks has Google come up with?"

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

"Have you started focusing on studying this area?"

Gu Ningzha 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. It can still quickly learn Go by itself without any human input. "

"Oh? That's interesting." Wu Bin nodded and showed interest.

Seeing Wu Bin's glowing eyes, Gu Ningshan snickered first, and then said: "This time Zero should have really learned the rules of Go by himself. The AI ​​has begun to gradually adjust the parameters from the lost or won games. In this way, It has changed from using data streams to brute force the opponent's chess moves to actually choosing moves that are beneficial to winning the game."

Wu Bin: "How was the effect?"

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

"It's interesting. If you don't bully humans, then start a civil war..."

After the Master brutally tortured almost all human elite chess players, Google immediately announced that it would no longer participate in any chess competitions between humans and machines in the future. It would typically pretend to be B and then run away.

While chatting, the two of them had arrived at the Golden Arches. As usual, Wu Bin ordered a Big Mac set meal for Gu Ningshan. At first, the girl said that there was no way she could eat the Big Mac because it was so big, but then It turns out that one is not enough for her to eat!

"Would you like another box of chicken nuggets?" Wu Bin turned to ask Gu Ningshan.

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

"Okay, I'll eat it myself."

After ordering the meal, the two of them found a seat and sat down casually with their plates. Wu Bin picked it up and took a sip before asking: "What do you think after seeing this Zero?"

"How should I put it~" Gu Ningshan thought as she tore open the ketchup, "I think a single algorithm that can solve multiple complex problems is the first and most important step to create a machine learning system to solve practical problems. .”

"Oh~ It's very profound. It seems that you have studied well recently." Wu Bin smiled and praised, "By the way, what do you think of the level of professors in the Institute of Letters?"

Although HKUST has had the idea of ​​opening a college of artificial intelligence, it has not yet been implemented. Therefore, artificial intelligence is still classified in automation and computer-related majors.

Gu Ningshan, who has a strong interest in artificial intelligence, is also very resolute. She transferred to the information technology department in a matter of minutes. From now on, she should be very satisfied with her choice.

"It's quite impressive." Gu Ningshan nodded, "Oh, by the way, Professor Zhang will give a lecture in the floating lecture hall next week. You should be interested in attending."

"Which Zhang...huh!? Is it Professor Zhang Yaqin?" Wu Bin exclaimed.

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

Entering the junior class at the age of 12, the first full-scoring doctorate in the history of George Washington University, and the former president of Baidu, these are the auras surrounding Zhang Yaqin. It is not an exaggeration to say that he is the most successful person in the junior class of HKUST.

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

Wu Bin took a bite of his burger and asked vaguely: "What kind of lecture is it?"

"It seems to be related to 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 U.S. patents, which is completely resting on a golden mountain. Moreover, he kept a low profile after resigning as the president of Baidu, so Wu Bin thought he was already enjoying life.

"I don't know if I do scientific research or not. Anyway, you will know if you go and listen. If you want to come, I can save 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 your little tail away and go back to the topic just now. I think the emergence of ZERO means that Google is no longer eager to win and starts to pay attention to learning."

"This is the concept. This time they used 5,000 TPUs on ZERO, combined with deep neural networks, enhanced learning algorithms and general tree search. I am now 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 experienced a very exciting adventure in life, and now I’m back from the adventure. Anyway, I’ve started updating!
