Game over! Computer wins series against Go champion

0

SEOUL – A Google-developed computer programme took an unassailable 3-0 lead in its match-up with a South Korean Go grandmaster on Saturday – marking a major breakthrough for a new style of “intuitive” artificial intelligence (AI).

The programme, AlphaGo, secured victory in the five-match series with its third consecutive win over Lee Se-Dol – one the ancient game’s greatest modern players with 18 international titles to his name.

Lee, who has topped the world ranking for much of the past decade and confidently predicted an easy victory when accepting the AlphaGo challenge, now finds himself fighting to avoid a whitewash defeat in the two remaining games on Sunday and Tuesday.

“AlphaGo played consistently from beginning to the end while Lee, as he is only human, showed some mental vulnerability,” said one of Lee’s former coaches, Kwon Kap-Yong.

“The machine was increasingly gaining the upper hand as the series progressed,” Kwon said.

For AlphaGo’s creators, Google DeepMind, victory goes far beyond the $1.0 million dollar prize on offer in Seoul, proving that AI can go beyond superhuman number-crunching.

The most famous AI victory to date came in 1997 when the IBM-developed supercomputer Deep Blue beat Garry Kasparov, the then-world class chess champion, in its second attempt.

But a true mastery of Go, which has more possible move configurations than there are atoms in the universe, had long been considered the exclusive province of humans – until now.

AlphaGo’s creators had described Go as the “Mt Everest” of AI, citing the complexity of the game, which requires a degree of creativity and intuition to prevail over an opponent.

AlphaGo first came to prominence with a 5-0 drubbing of European champion Fan Hui last October, but it had been expected to struggle against 33-year-old Lee.

Creating “general” or multi-purpose, rather than “narrow”, task-specific intelligence, is the ultimate goal in AI – something resembling human reasoning based on a variety of inputs and, crucially, self-learning.

In the case of Go, Google developers realised a more “human-like” approach would win over brute computing power.

The 3,000-year-old Chinese board game involves two players alternately laying black and white stones on a chequerboard-like grid of 19 lines by 19 lines. The winner is the player who manages to seal off more territory.

AlphaGo uses two sets of “deep neutral networks” that allow it to crunch data in a more human-like fashion – dumping millions of potential moves that human players would instinctively know were pointless.

It also employs algorithms that allow it to learn and improve from matchplay experience.

It is able to predict a winner from each move, thus reducing the search base to manageable levels – something co-creator David Silver has described as “more akin to imagination”.

Bukit Batok MP David Ong resigns, by-election to follow

0

SINGAPORE – Member of Parliament for Bukit Batok Single Member Constituency (SMC) David Ong has resigned from the People’s Action Party (PAP).

In a statement, the Prime Minister’s Office (PMO) said a by-election will be held in the SMC “in due course”.

In the meantime, Desmond Lee, Senior Minister of State for Home Affairs and National Development, will be in charge of the SMC.

The PMO also released Ong’s resignation letter addressed to Prime Minister Lee Hsien Loong, who is also Secretary General of the PAP.

Ong said in his letter that he was resigning for personal reasons and “with a heavy heart”.

He thanked the Bukit Batok residents for their support and expressed his appreciation to the grassroot leaders and the PAP. In the same letter, he also apologised for stepping down prematurely.

In his reply, PM Lee commended Ong for serving diligently as an MP, first for Jurong GRC and then for Bukit Batok SMC.

“As an MP, you worked hard to strengthen the Bukit Batok community, building up a team of volunteers and community partners to help residents in need,” PM Lee wrote.

Tesla looking to test car slapped with $15k levy again

0

Singapore – TESLA is working with Singaporean authorities to conduct tests again on one of its cars here that was slapped with a S$15,000 carbon emissions surcharge, a spokeswoman of the US car company has told BT.

The Land Transport Authority (LTA) of Singapore said on Thursday that it imposed the surcharge on an imported and used Tesla Model S – the first and only one here – because tests showed that its power consumption hit 444 watt-hour/km.

The car is owned by Joe Nguyen, senior vice-president at an Internet research firm, who paid almost S$400,000 for it and imported it from Hong Kong.

Factoring in 0.5g/watt-hour of carbon dioxide emissions from powering the car, its emission was deemed to be 222g/km, which put it in the S$15,000 surcharge band under the Carbon Emissions-based Vehicle Scheme (CEVS).

Tesla Motors previously informed LTA that the energy consumption of the Model S was 181 watt-hour/km when it left the Tesla factory on June 28, 2014. This means that the brand new Model S would have qualified for a S$30,000 rebate, LTA noted.

The authority had said that it and VICOM Emission Test Laboratory, which conducted the test, were in touch with Tesla’s engineers to see how testing processes for electric cars can be done.

Tesla told BT on Friday that it was also looking to test Mr Nguyen’s car again.

“We believe the test was likely not properly conducted, and we are working cooperatively with LTA to test the car again,” said Scarlett Au, a spokeswoman for Tesla, in response to BT’s queries, which included what the maker thought of the car seeing its power consumption increasing to 444 watt-hour/km in a little under two years.

Tesla said Model S cars have a much lower carbon footprint than cars powered by petrol, evidenced by the 181 watt-hour/km power consumption of a brand new car.

In addition, oil extraction, distribution and refining would result in about 25 per cent more to calculate the real carbon footprint of petrol-powered cars, Ms Au said.

“Moreover, as Singapore increases the percentage of grid power from solar and wind, the CO2 (carbon dioxide) from electricity drops with each passing year,” she said, referring to the power that electric vehicles draw from power grids.

A specialist on renewable energy that BT spoke to, however, said that there is a certain limit to how much Singapore can diversify its sources of energy – which would have an impact on the minimum level of emissions the national power grid produces.

“In America, you can install large numbers of solar panels in the desert. In Singapore, we have to be dependent on rooftops on buildings. There’s only so much you can do,” said Ashish Sethia, head of India and South-east Asia for gas and power at Bloomberg New Energy Finance.

Mr Sethia agreed that it was reasonable to consider how much power an electric vehicle draws from the grid. “That’s carbon produced from using the grid. There has to be some carbon footprint right there.”

Tennis: Venus Williams ends Indian Wells boycott, sister Serena wins opener

0

USA – Venus Williams finally made peace with Indian Wells tennis fans Friday by ending her 15-year boycott of the hardcourt tournament, but she couldn’t put away her Japanese opponent.

Williams’ hopes for a storybook ending in her return to the California desert were dashed when she lost 6-4, 6-3 to qualifier Kurumi Nara in a second-round match delayed 30 minutes because of a storm.

The 35-year-old Williams received a hearty reception from the main stadium crowd of about 7,000, with some in attendance standing up to cheer.

But it was a more low-key response than the 57-second standing ovation that Serena received here last year when she ended her 14-year boycott of the joint WTA and ATP Tour event.

“It is time to move on and let the past be the past. When I was out there I didn’t think back. It was a long time ago,” said Venus, who was seeded 10th in the tournament.

In 2001, spectators at Indian Wells booed Serena during the final and jeered her sister and father Richard Williams when the pair arrived to watch the match. Richard Williams alleges that racist comments were directed at them.

“We could have come back here and everyone could have picked up where they left off,” Venus said.

“There had to be a change of attitude on both ends. It isn’t always easy. Us, the fans and the city had to have a positive attitude about it.” Venus’ upset loss to the world number 89 dashed any hopes that the Compton, California, sisters could meet in the quarter-finals at Indian Wells, one of the biggest events on the tennis calendar outside of the Grand Slams.

Serena breezed through her opening match on Friday, beating German qualifier Laura Siegemund 6-2, 6-1.

Serena advances to the third round where she will face unseeded Yulia Putintseva of Kazakhstan.

Venus is a former world number one and the first African-American to become the top-ranked women’s player in the world.

Tenth-seeded Venus blasted three aces but made four double faults and won just four of 12 break points in the 101-minute match.

A rain and wind storm struck in the middle of the first set as the driving showers sent spectators and players running for cover.

“It was a tough day,” Venus said. “Very tough conditions. Just brutal out there.” Venus added that luck wasn’t on her side Friday.

“She played well. Her shank shots kept going in. I thought, ‘How do I get some of mine in?'” Venus said.

This was Serena’s first competitive match since her Australian Open final defeat to Angelique Kerber.

The world number one didn’t look rusty from the nearly two-month layoff as she saved three-of-three break points on her serve and broke the German’s serve four times.

“The key was my intensity,” Serena said. “She was close to breaking me at one point and I knew if I didn’t give 100 percent at that point it was going to be a long night.” Meanwhile, Polish third seed Agnieszka Radwanska survived a scare to defeat Slovakian veteran Dominika Cibulkova 6-3, 3-6, 7-5 in her opening match.

She advances to the third round, where she will face Monica Niculescu, who beat Heather Watson 6-4, 2-6, 6-2.

In other women’s matches on Friday, defending champion Simona Halep cruised past American Vania King 6-1, 6-1; eighth seed Petra Kvitova needed three sets to beat Danka Kovinic 6-3, 4-6, 7-6 (7/5); and Jelena Jankovic dominated Carina Witthoeft 6-1, 6-3.

On the men’s side, qualifier Bjorn Fratangelo defeated Teymuraz Gabashvili 6-4, 6-4 to set up a second round clash with world number one Novak Djokovic, who is hoping to win his third straight Indian Wells title.

Drug confession is a bitter pill to swallow for sporting superstar

0

“We once knew a girl named Maria But suddenly that name Will never be the same.”

With apologies to Leonard Bernstein and Stephen Sondheim, whose lyrics I have altered, their enduring love song of the 60s musical West Side Story now seems to have less innocence.

The most famous girl named Maria – Maria Sharapova – may not be all that she seemed.

When she donned a widow’s black garb for her press conference in Los Angeles on Monday, it was to pre-empt the announcement by the World Anti-Doping Agency (Wada) that she had tested positive for a banned substance during the Australian Open in January.

“I take full responsibility for it,” Sharapova said, hand quite literally on heart.

“For the past 10 years,” she explained, “I have been given a medicine called mildronate by my family doctor and a few days ago after I received the ITF (International Tennis Federation) letter I found out that it also has another name of meldonium which I did not know.

“It is very important for you to understand that for 10 years this medicine was not on Wada’s banned list and I had legally been taking the medicine for the past 10 years.

“But on Jan 1 the rules had changed and meldonium became a prohibited substance which I had not known. I was given this medicine by my doctor for several health issues that I was having in 2006.”

She knew; but she didn’t know.

Over the past week, the world’s most famous, and richest female tennis player (though not the best; that would be Serena Williams) has divided opinion.

There remain more questions than answers, but Sharapova’s American lawyer, John Haggerty, believes she has a number of “mitigating factors”.

One suggestion was that they might seek a reduction in her inevitable suspension by applying for a retrospective Therapeutic Use Exemption (TUE).

Such exemptions are allowed, and widely applied across many sports. But, obviously, a competitor has to disclose any ailment that might require such medication – and Sharapova had not done so.

Her story during Monday’s (early Tuesday morning Singapore time) press announcement was that she was getting sick very often, that she had a deficiency in magnesium, that she had irregular electrocardiogram (ECG) results, and has a family history of diabetes.

The kind of questions that still need answers would start with just why Sharapova, now 28, was prescribed a Latvian drug by her “family doctor”.

Maria was taken by her father, Yuri, to the Nick Bollettieri academy in Florida when she was just seven years old.

She became one of those tennis prodigies, winning tournaments and big prize money when it was barely legal for a girl to work.

The sheer effort those precocious kids put into their strokes, evident in the accompanying shrieks, have long been a disturbing aspect of this phenomenon.

However, the family doctor mentioned, but not named, may hold some answers. If he or she is American, why was Sharapova prescribed a Latvian drug that is not registered in the US?

And why that particular drug, which the manufacturers say is for Alzheimer’s, angina and serious heart conditions – and generally recommended for use over four to six weeks?

Haggerty later told media that Sharapova has a family history of diabetes and heart conditions, and she was diagnosed in 2006 with asthenia – a lack of energy or strength.

Sharapova had said that she continued taking the medicine while regularly checking the list to ensure that it was not a banned substance.

She had received a letter and an e-mail in December that forewarned athletes that meldonium was being added to the prohibited list from Jan 1.

A rational person might ask why Sharapova missed the warnings that Wada says were repeated five times to all sportsmen and women since last autumn.

We might question not only how she missed it, but also that no one in her entourage was aware of it. Her coach is a Dutchman, her fitness trainer is Japanese, her physio French, her hitting partner is a German male, and both her agent and her legal adviser are Americans.

Those experts are paid out of Sharapova’s estimated wealth of almost US$200 million (S$275 million), and none of them apparently read the list and knew what drugs she has been using for 10 years?

The global reaction also sends mixed signals. Former world No. 1 Caroline Wozniacki, now ranked No. 25, said: “Any time we take any medication, we double and triple-check. Even a thing like cough drops and nasal spray can be on the banned list, so as athletes we make sure not to take something that would put us in a bad situation.”

Yet Sharapova put herself in that situation over an increasingly suspect drug.

Serena Williams praised Sharapova for the way she took responsibility for her actions: “That takes courage and heart.”

However, Nike, TAG Heuer and Porsche, three of her major sponsors, either ended or suspended their deals with her.

Taking the contrary view, the owner of Head, whose rackets Sharapova endorses, took the view that she made “an honest mistake” and, rather than being banned, she should be encouraged to teach tennis to kids over a three-month period of penance.

“I trust what she is saying is the truth,” said Johan Eliasch, the boss of Head. “She says she only received certain dosages and those dosages have been significantly below what would be performance-enhancing.

“I believe she’s been transparent about it – and if she hasn’t, then my reasoning fails.” One man who still thinks of Maria as the most beautiful word he ever heard.
