Google's AlphaGo takes on Chinese Go master in best of three matches

Google's AlphaGo now on the Go

Demis Hassabis co-founder of Google's artificial intelligence startup DeepMind

From May 23 to 27, Ke will play three rounds against AlphaGo in Wuzhen, Zhejiang province. Sedol and most observers noticed that AlphaGo was smart, but still exhibiting traits more characteristics of human players.

Ke Jie, China's top Go player, is taking on Google's AlphaGo in a three-game match starting from today in east China's Wuzhen, initiating another head-on confrontation between human wisdom and artificial intelligence. "#AlphaGo won by just half a point, the closest margin possible". Google has "shown" it (as it learns through computer vision) millions of matches between professional (human) Go players, and the company also made AlphaGo play against itself, so it could learn from its own mistakes. The second game will be played on Thursday before the event wraps up on Saturday. It also sets out to look at how machine learning may be able to solve problems using methods that human experts may not have considered.

Competing in the contest is the 2.0 version of AlphaGo, which has adopted a new algorithm model different from the AlphaGo 1.0 that has achieved a feat of 60 wins and 0 losses, defeating all challengers including Ke Jie.

DeepMindGo is an ancient two-player board game that was invented in China some 3,000 years ago.

The program's margin of victory tendencies weren't exposed during its highly publicized matches against South Korean grandmaster Lee Sedol previous year because all of those games ended in one player resigning before scores were counted. But perhaps the first event that made the public take note of the rise of AI, or artificial intelligence, came a few months earlier than that.




Hassabis of DeepMind spoke in a greeting before the match about the broad applicability of the AI technology powering AlphaGo.

"For the first time, AlphaGo was quite human-like", Ke said.

On Monday night, Ke said on China's Twitter-like Weibo platform that "the advancement of AI has far exceeded our imagination" but added he would never play it again after this week. "There are 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 possible positions - that's more than the number of atoms in the universe, and more than a googol times larger than chess".

"I am still excited to see the games!" says Lee Ha-jin, who doesn't particularly seem to mind if AlphaGo prevails.
