Google's AlphaGo AI takes on China
Beijing - A machine built by Alphabet has officially defeated the world’s top-ranked player of the ancient board-game Go, a decisive demonstration of artificial intelligence’s ability to master some of the most complex human endeavours.
AlphaGo bested Ke Jie, a 19-year-old Chinese prodigy who boasted a year ago that the AI could never beat him at a game he’s played professionally since the age of 10. But on Thursday, the world No. 1 lost his second match in a three-game series in the tourist town of Wuzhen, China.
The victory, which came during a week-long conference dedicated to AI, is a show of strength for the parent of Google as it attempts to find a way to offer its services in the country.
The search giant’s most popular services from Gmail to YouTube have been blocked by Chinese authorities since 2014.
Go, invented in China more than 2 000 years ago, is a battle for territory involving the placement of white or black stones on a grid. AlphaGo’s success has stunned experts, who thought it would take as much as a decade before AI could beat top-ranked professional players of the game.
Ke employed an ambitious strategy, opening up multiple fronts across the board in a move that online commentators said was an attempt to take advantage of AlphaGo’s preference for certainty over game points. But the AI-player gradually closed up opportunities and gained a large block of territory that would’ve been hard to break up.
The Chinese player declared AlphaGo a "god"of the game after his first defeat on Tuesday. While the final scores were relatively even, experts said this was largely because AlphaGo played defensively to shore up a near-assured victory.
Executive chairperson Eric Schmidt and a cadre of mid-level Chinese government officials kicked off the summit in Wuzhen this week.
Google experts and prominent local academics exchanged notes while executives promoted Alphabet’s expertise in AI and suite of technologies, including Tensor Processing Unit chips designed to supercharge the training of computer systems.

Cape Town - Western Cape Major-General Jeremy Vearey was only acting as deputy provincial commissioner for detective services, and was not entitled to keep the position, the lawyer for the SAPS officials contesting his ''demotion'' dispute said in the Labour Court in Cape Town on Friday.
''The mere fact that you are acting in a position does not mean you are appointed to that position,'' said advocate Alec Freund, SC.
Freund is representing the Minister of Police, the Acting National Commissioner of Police, the Provincial Commissioner of Police, SAPS Human Resources, Major-General Mzwandile Tito, Major-General Patrick Mbotho and the SA Police Services in the challenge by two high ranking officers.
''It does not mean you are entitled to that position.''

Freund submitted to Judge Hilary Rabkin-Naicker that when appointed to act in a position, there are performance expectations, ''but it doesn't give you a right to stay there''.
Not permanently appointed
Vearey, and provincial colleague Peter Jacobs, who headed the Western Cape's Crime Intelligence Unit, are alleging they were suddenly demoted on 13 June 2016 for ulterior motives.
Vearey was sent to a position he had previously filled - commander of the Cape Town cluster of police stations, while Jacobs was appointed Wynberg cluster commander.
They are asking the Labour Court to have the decision reviewed, with the support of the Police and Prisons Civil Rights Union, which believes their removals were irrational and unlawful and could have wider ramifications for other members.
But Freund said that it was only Jacobs who was transferred.
He submitted that Vearey had never even been permanently appointed to the detective services post.
Vearey said that between August 2014 and February 2015, he was cluster commander of Cape Town.
Between 9 February 2015 and June 2016, he served in the acting capacity at detective services.
To prove that he had been acting in the post, Freund said Vearey's performance agreement noted that he was acting.
He would have been able to argue that he had been transferred if he had actually been appointed to the deputy post full time, continued Freund.
''His position, in which he is placed, is the cluster commander, Cape Town Central,'' he said.
He conceded that there was a ''fairly fundamental'' restructuring at the time, but not all positions were affected, including Vearey's.
On Thursday, Vearey and Jacobs' counsel argued that their removals were irrational and unlawful, and made no sense given their specialised gang knowledge and serious gang-related crime in the Western Cape.
The application continues.
