India, Solar Technology, and the Monkey Problem

Fri, 08/07/2015 - 00:00

As the government embarks on an ambitious renewables program, researchers seek technology solutions suited to India’s unique conditions.

In central Karnataka state, 120 miles north of Bangalore, the lush jungle of India’s west coast gives way to dry scrubland. Sunflowers, onions, chilis, and groundnuts grow in parched fields. In scattered, populous villages, concrete buildings alternate with ramshackle thatched huts. Cows nose through the garbage, and wooden carts drawn by horned oxen crowd the streets. Rough brick-producing factories belch black smoke into the air. Much of the scene appears as it did a century ago. But in a walled compound just beyond the town of Challakere sits an installation that could hold one of the keys to India’s energy future.

Teaching Machines to Understand Us

Thu, 08/06/2015 - 00:00

A reincarnation of one of the oldest ideas in artificial intelligence could finally make it possible to truly converse with our computers. And Facebook has a chance to make it happen first.

The first time Yann LeCun revolutionized artificial intelligence, it was a false dawn. It was 1995, and for almost a decade, the young Frenchman had been dedicated to what many computer scientists considered a bad idea: that crudely mimicking certain features of the brain was the best way to bring about intelligent machines. But LeCun had shown that this approach could produce something strikingly smart—and useful. Working at Bell Labs, he made software that roughly simulated neurons and learned to read handwritten text by looking at many different examples. Bell Labs’ corporate parent, AT&T, used it to sell the first machines capable of reading the handwriting on checks and written forms. To LeCun and a few fellow believers in artificial neural networks, it seemed to mark the beginning of an era in which machines could learn many other skills previously limited to humans. It wasn’t.

Tech’s Enduring Great-Man Myth

Tue, 08/04/2015 - 00:00

The idea that particular individuals drive history has long been discredited. Yet it persists in the tech industry, obscuring some of the fundamental factors in innovation.

Since Steve Jobs’s death, in 2011, Elon Musk has emerged as the leading celebrity of Silicon Valley. Musk is the CEO of Tesla Motors, which produces electric cars; the CEO of SpaceX, which makes rockets; and the chairman of SolarCity, which provides solar power systems. A self-made billionaire, programmer, and engineer—as well as the inspiration for Robert Downey Jr.’s Tony Stark in the Iron Manmovies—he has been on the cover of Fortune and Time. In 2013, he was first on the Atlantic’s list of “today’s greatest inventors,” nominated by leaders at Yahoo, Oracle, and Google. To believers, Musk is steering the history of technology. As one profile described his mystique, his “brilliance, his vision, and the breadth of his ambition make him the one-man embodiment of the future.”

Military Robots: Armed, but How Dangerous?

Mon, 08/03/2015 - 10:13

Will artificial intelligence inevitably make warfare worse?

An open letter calling for a ban on lethal weapons controlled by artificially intelligent machines was signed last week by thousands of scientists and technologists, reflecting growing concern that swift progress in artificial intelligence could be harnessed to make killing machines more efficient, and less accountable, both on the battlefield and off. But experts are more divided on the issue of robot killing machines than you might expect.

India Loves MOOCs

Mon, 07/27/2015 - 00:00

In a country of rigid teaching styles and scarce university slots, students and professors are exploring what online learning can be.

How does a talented Indian teenager like Gaurav Goyal make his mark on the world? Ordinarily, his destiny would have been set on the morning in 2008 when he took his country’s toughest college placement exam: the IIT Joint Entrance Exam. More than 300,000 students attempted the test that year; only 8,652 qualified for a spot at one of the ultra-elite Indian Institutes of Technology.

Personal Robots: Artificial Friends with Limited Benefits

Fri, 07/24/2015 - 00:00

Several companies are developing appealing robot companions, but they aren’t yet capable of helping out around the house.

If you visit Softbank’s flagship store in downtown Tokyo, you may be greeted by a charming, slightly manic new member of the staff: a gleaming white humanoid robot that gestures dramatically, cracks odd jokes, and occasionally breaks out dancing to music emanating from its own body. If you laugh at these antics, and the robot can see your face, it will quite likely giggle along with you.

Inside Amazon
