With this level of artificial intelligence, bugs are not common.

Over the years, AlphaGo has only had an obvious bug when playing against chess players from South Korea.

After that, AlphaGo's team optimized the algorithm, and this bug was fixed.

"Is it because of another upgrade?"

"No, we just upgraded the computing power, and the core algorithm has not changed from before."

"In that case, why did this happen?"

"When AlphaGo encounters its own very rare moves, it will fall into a search dilemma. And if AlphaGo feels that its winning rate is already very low, it is prone to this kind of program crash."

Hearing this explanation, the leader of Google was also very puzzled.

"Hasn't our artificial intelligence already played countless games? How could it encounter some rare moves? Couldn't it be that they have grasped our shortcomings and made a rare wrong move on purpose? "

"No, this can't be said to be a wrong move, but a very rare coup."

At this time, a staff member said.

This staff member is a software engineer and an amateur six-dan chess player, who plays a very important role in the development team of AlphaGo.

"This move is rarely seen in the game of professional chess players, because under normal circumstances, humans think that this is a move that will make them passive. The complexity of the change is simply beyond the capabilities of the human brain. But For an artificial intelligence with extremely strong computing power, this may be a good hand instead."

As the staff member said, with the appearance of this bug, AlphaGo was devastated and repeatedly made stupid moves.

This is also the difference between artificial intelligence and humans.

When the artificial intelligence determines that its winning rate is already very low, it will start to play randomly, because no matter where it goes, it has no effect on the final outcome.

Seeing that AlphaGo's moves began to become outrageous, AlphaGo's team had no choice but to quickly choose to admit defeat.

If it goes on like this, maybe AlphaGo will fill in all his eyes, and finally the whole chessboard will be the territory of black chess.

Seeing such a scene, Nie Jie, the commentator in the CCTV live broadcast room, was undoubtedly the happiest person.

"It seems that AlphaGo has a serious bug just like before. I don't really understand the logic behind these artificial intelligences, but I guess that the big reason is that our island artificial intelligence has stepped out of AlphaGo. A move that Fagou didn't expect. This shows that Sea Island's artificial intelligence greatly surpasses Alphagou in terms of game experience and computing power. It's just a pity that this game ended too quickly."

Nie Jie couldn't help but secretly rejoice in his heart. The upgraded version of AlphaGo this time has not lasted as long as he and the artificial intelligence of the island.

If you round it up, Nie Jie's strength is already higher than that of Alpha Gou.

Even though he thought so in his heart, Nie Jie also knew that he was definitely no match for either of these two artificial intelligences.

But no matter what, as long as China's artificial intelligence can defeat the artificial intelligence of the United States, it will be a refreshing thing.

"As a professional software engineer, let me explain the possible reasons for the bug in AlphaGo."

At this time, another commentator suddenly said.

The commentator is Chen Yuchang, not only a professional software engineer, but also involved in the research of Penguin Go artificial intelligence.

"Because all the Go artificial intelligences are now based on deep learning systems to improve their chess skills, instead of using exhaustive methods. This makes each artificial intelligence may have bugs. More precisely , on this type of algorithm model, this kind of bug is called overfitting.”

"Mr. Chen, can you explain what overfitting is?" Nie Jie asked.

While cooperating with Chen Yuchang, Nie Jie did have some interest in this issue.

"The so-called overfitting can be understood as the decision-making error caused by the imbalance of AI data. As I said just now, the improvement of AI's chess power is derived from its own deep learning. For example, AI is playing against itself. When playing chess, I have accumulated 10,000 games. Some chess shape changes have accumulated more, and some chess shape changes have accumulated less. Like a duel with less chess shape changes, the overall winning rate is relatively small, because Too much chance..."

After listening to Chen Yuchang's explanation, Nie Jie basically understood the reason.

"Is it understandable in this way? For example, for a change, the AI ​​has only accumulated ten rounds, won three rounds and lost seven rounds, and thinks that this change's winning rate is only 30%. But in fact, if the accumulated If there is enough data, its true winning rate may be far higher than this data?"

"That's right, that's what it means. To put it simply, as long as you keep making changes that the AI ​​hasn't seen, it will easily lead to bugs."

"I see. If I had known about this bug earlier, when I played chess with AlphaGo, I would have used more strange moves. For example, the first step is to use Tianyuan or something, maybe I can steal a game Victory." Nie Jie joked.

At this time, in the island quantum laboratory, the atmosphere is also peaceful.

As everyone expected, Sea Island AI won the first game of chess.

Even in black chess, which is not dominant, Sea Island AI still has a crushing advantage.

It's just that Xu You didn't expect that the upgraded AlphaGo would be overwhelmed so quickly.

"It's difficult to test the true strength of the island's artificial intelligence in such a chess game." Xu You said helplessly.

Xu You, the creator of the island's artificial intelligence, understands why AlphaGo suddenly failed just now.

It must be the artificial intelligence of the island, who accidentally made a rare move by AlphaGo, which directly triggered a hidden bug.

This kind of bug cannot be completely avoided. Only by relying on a large number of duels can the frequency of bug occurrence be reduced.

Compared with supercomputers, the calculation speed of quantum computers is much faster, so it can accumulate a huge number of games in a short period of time.

It can be said that there is a very low probability of causing bugs in the island's artificial intelligence.

"If it wasn't for the fact that this was a live broadcast on the entire network, I would have given up to the AI ​​of the island directly." Xu Youxin said.

But Xu You still couldn't relax his vigilance when he only finished one game of Sanfanqi.

Xu You decided that if he could easily win the second set, he could give way to AlphaGo in the last set to test where the upper limit of the island's artificial intelligence is.
