‘Deep Learning’ Professor to Head Facebook AI Lab

December 16th, 2013

Via: New Yorker:

Earlier today, Facebook announced that one of the most prominent artificial-intelligence researchers in the world, Yann LeCun, will be joining the company to direct a massive new A.I. effort spread across offices in California, New York, and London. While it might sound like just another Facebook hire, the move, which LeCun describes as having “the long-term goal of bringing about major advances in artificial intelligence,” points to a new layer in Facebook’s ambitions, as well as a shift in the research and development of artificial intelligence.

Even before he approaches these larger challenges, LeCun can immediately get to work by mining Facebook’s enormous library of user-submitted photographs. Already the largest such photo library in the world, users add roughly three hundred and fifty million photos to it every day. Earlier this year, when Facebook announced Graph Search, it was remarkable for changing the search paradigm from page-based, like Google results from 2003, to something that is knowledge-based and capable of aggregating information from across different sources. For example, I can ask Facebook to show me friends from college who are married and live in Boston, and it generates the data instantly, rather than showing me a pre-existing Web page. However, as I noted when Graph Search was announced, it’s not very good at extracting meaning from photos. I can’t ask Facebook to show me pictures from my college friends in New York City that have babies and cats in them. LeCun’s work could change that, making it possible, for example, to even ask Facebook “Which of my friends had babies recently?” and get a reasonable answer, complete with photos, even if the new parents had never explicitly said that a baby was born.


Tamerlan Tsarnaev Heard Voices in His Head

December 16th, 2013

Via: Yahoo:

Suspected Boston marathon bomber Tamerlan Tsarnaev was tormented by voices in his head, according to the Boston Globe, which published the results of a five-month investigation into the attack on Sunday.

“He believed in majestic mind control, which is a way of breaking down a person and creating an alternative personality with which they must coexist,” Donald Larking, a 67-year-old who attended a Boston mosque with Tamerlan, told the Globe. “You can give a signal, a phrase or a gesture, and bring out the alternate personality and make them do things. Tamerlan thought someone might have done that to him.”


Bottled Water Containing Di(2-Ethylhexyl) Fumarate and 24,000+ Other Chemicals

December 14th, 2013

Via: Natural Society:

Several companies have stopped using BPA in plastic production due to consumer outrage, but just because a plastic container says it is “BPA Free” doesn’t mean it’s free of potentially harmful chemicals. As a matter of fact, recent research out of Germany indicates there are more than 24,000 of such chemicals in any given bottle of water—with some of them causing serious hormone-disrupting effects.

According to the story from Goethe University Frankfort, the researchers tested 18 different bottled water products in an effort to look for endocrine disrupting chemicals, or EDCs. They found far more than expected, identifying 24,520 different chemicals in their testing. After isolating the chemicals and determining their impact on the body, the researchers narrowed down those with anti-estrogenic properties to one: DEHF or di(2-ethylhexyl) fumarate. This finding was of major concern.

Out of the 18 different bottled water products, 13 had “significant” anti-estrogenic activity, and 16 out of 18 inhibited the body’s androgen receptors by 90%. In other words, the bottled water was largely wrecking havoc on the human body.

China Landed Rover on Moon

December 14th, 2013

Update: Chinese Rover Landed on Moon and Launched Successfully

Via: CNN:

China’s first lunar rover deployed successfully from the unmanned spacecraft Chang’e-3 that landed on the moon Saturday.

Jade Rabbit (called Yutu in Chinese) is a six-wheeled lunar rover equipped with at least four cameras and two mechanical legs that can dig up soil samples to a depth of 30 meters.

The solar-powered rover will patrol the moon’s surface, studying the structure of the lunar crust as well as soil and rocks, for at least three months. The robot’s name was decided by a public online poll and comes from a Chinese myth about the pet white rabbit of a goddess, Chang’e, who is said to live on the moon.

Weighing 140 kilograms, the slow-moving rover carries an optical telescope for astronomical observations and a powerful ultraviolet camera that will monitor how solar activity affects the various layers — troposphere, stratosphere and ionosphere — that make up the Earth’s atmosphere, China’s information technology ministry said in a statement.

The Jade Rabbit is also equipped with radioisotope heater units, allowing it to function during the cold lunar nights when temperatures plunge as low as -180°C (-292°F).

The moon exploration makes China one of only three nations — after the United States and the former Soviet Union — to “soft-land” on the moon’s surface, and the first to do so in more than three decades.

Via: BBC:

China is set to land a robotic rover on the surface of the Moon, a major step in the Asian superpower’s ambitious programme of space exploration.

On Saturday afternoon (GMT), a landing module will undergo a powered descent, using thrusters to perform the first soft landing on the Moon in 37 years.

Several hours later, the lander will deploy a robotic rover called Yutu, which translates as “Jade Rabbit”.

The touchdown will take place on a flat plain called the Bay of Rainbows.

The Chang’e-3 mission launched on a Chinese-developed Long March 3B rocket on 1 December from Xichang in the country’s south.

“On the evening of December 14, Chang’e-3 will carry out a soft landing on the lunar surface,” said a post on the mission’s official blog on Sina Weibo, the Chinese version of Twitter.

The task was described as the mission’s “most difficult” in the post, written by the Chinese Academy of Sciences on behalf of the space authorities.

It is the third robotic rover mission to land on the lunar surface, but the Chinese vehicle carries a more sophisticated payload, including ground-penetrating radar which will gather measurements of the lunar soil and crust.


GOOGLE BUYS BOSTON DYNAMICS

December 14th, 2013

😯

Via: New York Times:

BigDog, Cheetah, WildCat and Atlas have joined Google’s growing robot menagerie.

Google confirmed on Friday that it had completed the acquisition of Boston Dynamics, an engineering company that has designed mobile research robots for the Pentagon. The company, based in Waltham, Mass., has gained an international reputation for machines that walk with an uncanny sense of balance and even — cheetahlike — run faster than the fastest humans.

It is the eighth robotics company that Google has acquired in the last half-year. Executives at the Internet giant are circumspect about what exactly they plan to do with their robot collection. But Boston Dynamics and its animal kingdom-themed machines bring significant cachet to Google’s robotic efforts, which are being led by Andy Rubin, the Google executive who spearheaded the development of Android, the world’s most widely used smartphone software.

The deal is also the clearest indication yet that Google is intent on building a new class of autonomous systems that might do anything from warehouse work to package delivery and even elder care.


NASA Unveils ‘Valkyrie’ Robot for DARPA Competition

December 13th, 2013

Via: IEEE Spectrum:

Valkyrie (officially designated “R5” by NASA) is a 1.9 meter tall, 125 kilogram, 44 degree of freedom, battery-powered humanoid robot. A team from NASA’s JSC in Houston, in partnership with the University of Texas and Texas A&M and with funding from the state of Texas itself, built the robot for the DRC, which will hold a preliminary competition later this month.

The challenge created by DARPA involves tasks like walking over uneven terrain, climbing a ladder, using tools, and driving. This means that Valkyrie has to be capable of operating in the same spaces that a person would operate in, under the control of humans who have only minimal training with robots, which is why the robot’s design is based on a human form. The overall goal of the DRC is to help drive innovation towards robots that are able to take over from humans directly, without needing any special accommodations. In that context, a human form makes sense because we’re humans, and these robots will be doing the jobs that we don’t want to be doing because they’re too dangerous.


Air Strike Kills 15 Civilians in Yemen by Mistake

December 13th, 2013

This is worth seeing:

Via: Reuters:

Fifteen people on their way to a wedding in Yemen were killed in an air strike after their party was mistaken for an al Qaeda convoy, local security officials said on Thursday.

The officials did not identify the plane in the strike in central al-Bayda province, but tribal and local media sources said that it was a drone.

“An air strike missed its target and hit a wedding car convoy, ten people were killed immediately and another five who were injured died after being admitted to the hospital,” one security official said.

Five more people were injured, the officials said.

The United States has stepped up drone strikes as part of a campaign against Al Qaeda in the Arabian Peninsula (AQAP), regarded by Washington as the most active wing of the militant network.

Yemen, AQAP’s main stronghold, is among a handful of countries where the United States acknowledges using drones, although it does not comment on the practice.


Meet the Robot Telemarketer Who Denies She’s A Robot

December 13th, 2013

Via: Time:

The phone call came from a charming woman with a bright, engaging voice to the cell phone of a TIME Washington Bureau Chief Michael Scherer. She wanted to offer a deal on health insurance, but something was fishy.

When Scherer asked point blank if she was a real person, or a computer-operated robot voice, she replied enthusiastically that she was real, with a charming laugh. But then she failed several other tests. When asked “What vegetable is found in tomato soup?” she said she did not understand the question. When asked multiple times what day of the week it was yesterday, she complained repeatedly of a bad connection.

Over the course of the next hour, several TIME reporters called her back, working to uncover the mystery of her bona fides. Her name, she said, was Samantha West, and she was definitely a robot, given the pitch perfect repetition of her answers. Her goal was to ask a series of questions about health coverage—”Are you on Medicare?” etc.—and then transfer the potential customer to a real person, who could close the sale.

ATF Uses Rogue Tactics in Storefront Stings Across Nation

December 13th, 2013

Via: Journal Sentinel:

The Journal Sentinel reviewed thousands of pages of court records, police reports and other documents and interviewed dozens of people involved in six ATF operations nationwide that were publicly praised by the ATF in recent years for nabbing violent criminals and making cities safer.

Agents with the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives employed rogue tactics similar to those used in Milwaukee in every operation, from Portland, Ore., to Pensacola, Fla.

Among the findings:

* ATF agents befriended mentally disabled people to drum up business and later arrested them in at least four cities in addition to Milwaukee. In Wichita, Kan., ATF agents referred to a man with a low IQ as “slow-headed” before deciding to secretly use him as a key cog in their sting. And agents in Albuquerque, N.M., gave a brain-damaged drug addict with little knowledge of weapons a “tutorial” on machine guns, hoping he could find them one.

* Agents in several cities opened undercover gun- and drug-buying operations in safe zones near churches and schools, allowed juveniles to come in and play video games and teens to smoke marijuana, and provided alcohol to underage youths. In Portland, attorneys for three teens who were charged said a female agent dressed provocatively, flirted with the boys and encouraged them to bring drugs and weapons to the store to sell.

* As they did in Milwaukee, agents in other cities offered sky-high prices for guns, leading suspects to buy firearms at stores and turn around and sell them to undercover agents for a quick profit. In other stings, agents ran fake pawnshops and readily bought stolen items, such as electronics and bikes — no questions asked — spurring burglaries and theft. In Atlanta, agents bought guns that had been stolen just hours earlier, several ripped off from police cars.

* Agents damaged buildings they rented for their operations, tearing out walls and rewiring electricity — then stuck landlords with the repair bills. A property owner in Portland said agents removed a parking lot spotlight,damaging her new $30,000 roof and causing leaks, before they shut down the operation and disappeared without a way for her to contact them.

* Agents pressed suspects for specific firearms that could fetch tougher penalties in court. They allowed felons to walk out of the stores armed with guns. In Wichita, agents suggested a felon take a shotgun, saw it off and bring it back — and provided instructions on how to do it. The sawed-off gun allowed them to charge the man with a more serious crime.

* In Pensacola, the ATF hired a felon to run its pawnshop. The move widened the pool of potential targets, boosting arrest numbers.Even those trying to sell guns legally could be charged if they knowingly sold to a felon. The ATF’s pawnshop partner was later convicted of pointing a loaded gun at someone outside a bar. Instead of a stiff sentence typically handed down to repeat offenders in federal court, he got six months in jail — and a pat on the back from the prosecutor.

“To say this is just a few people, a few bad apples, I don’t buy it,” said David Harris, a professor at the University of Pittsburgh School of Law and an expert on law enforcement tactics and regulation. “If your agency is in good shape with policy, training, supervision and accountability, the bad apples will not be able to take things to this level.”

New Zealand: Customs Seizes Man’s Electronic Equipment

December 13th, 2013

Via: New Zealand Herald:

A backpacker coming home for Christmas had every bit of electronic equipment stripped from him at the airport.

A Customs officer at Auckland International Airport took law graduate Sam Blackman’s two smartphones, iPad, an external hard drive and laptop – and demanded his passwords.

Mr Blackman, 27, who was breaking up travelling with his journalist fiance Imogen Crispe for a month back in New Zealand for Christmas, was initially given no reason why the gear was taken.

The only possibility of why it occurred was his attendance – and tweeting – of a London meeting on mass surveillance sparked by the Snowden revelations, he said.

However, a Customs official has since told him they were searching everything for objectionable material under the Films, Videos, and Publications Classification Act 1993.

Mr Blackman said he did not have anything of that nature and could not understand why he had been targeted.

Mr Blackman arrived in Auckland at 5.30am on a flight from Heathrow, travelling through San Francisco.

He declared loose-leaf tea he was carrying as he came through Customs and believed that was responsible for the extensive bag search to which he was subjected.

“He said ‘we’re not worried about the tea’,” Mr Blackman said of the Customs’ official.

The official then returned to going through the bag, pulling out electronic equipment as he did so. “We’re going to have to detain this,” Mr Blackman said he was told. “We’re going to have to send this to a forensic investigator.”

Mr Blackman said when he pulled a phone out of his pocket, the official also took that, refusing permission for him to call his parents who were waiting in the arrival lounge.

He said he was also told to provide passwords for the equipment. “That is a real invasion of privacy.”

One of the phones had no password but required a design to be traced on the screen. The official was unconcerned and said the forensic team would defeat security to access the device, Mr Blackman claimed.

He said he asked why the items were being confiscated and the official refused to say – or to say how long the items would be kept.
