This AI Hunts Poachers

The elephant’s new protector is PAWS, a machine-⁠learning and game-theory system that predicts where poachers are likely to strike

Every year, poachers kill about 27,000 African elephants—an astounding 8 percent of the population. If current trends continue, these magnificent animals could be gone within a decade.

The solution, of course, is to stop poachers before they strike, but how to do that has long confounded authorities. In protected areas like wildlife preserves, elephants and other endangered animals may roam far and wide, while rangers can patrol only a small area at any time. “It’s a two-part problem,” explains Milind Tambe, a computer scientist at the University of Southern California, in Los Angeles. “Can you predict where poaching will happen? And can you [target] your patrols so that they’re unpredictable, so that the poachers don’t know the rangers are coming?”

New artificial versions of the neurons and synapses in the human brain are up to 1,000 times smaller than neurons and at least 10,000 times faster than biological synapses, a study now finds.

These new devices may help improve the speed at which the increasingly common and powerful artificial intelligence systems known as deep neural networks learn, researchers say.

This morning, Amazon and iRobot announced “a definitive merger agreement under which Amazon will acquire iRobot” for US $1.7 billion. The announcement was a surprise, to put it mildly, and we’ve barely had a chance to digest the news. But taking a look at what’s already known can still yield initial (if incomplete) answers as to why Amazon and iRobot want to team up—and whether the merger seems like a good idea.
