    A new AI can focus on one voice in a crowd

    Much like someone listening to a conversation at a crowded party, a new artificial intelligence can tune out background noise in videos to hear what a particular person on screen is saying.

    Humans are naturally good at focusing on specific voices amidst the din — a phenomenon known as the cocktail party effect (SN Online: 4/29/14). But until now, programs designed to listen for specific...

    This AI uses the same kind of brain wiring as mammals to navigate

    An artificial intelligence that navigates its environment much like mammals do could help solve a mystery about our own internal GPS.

    Equipped with virtual versions of specialized brain nerve cells called grid cells, the AI could easily solve and plan new routes through virtual mazes. That performance, described online May 9 in Nature, suggests the grid cells in animal brains play a...

    First pedestrian death from a self-driving car fuels safety debate

    The first known pedestrian fatality involving a fully autonomous self-driving car will most likely raise questions about the vehicles’ safety.

    But “until we know what happened, we can’t really know what this incident means” for the future of self-driving vehicles, says Philip Koopman, a robotics safety expert at Carnegie Mellon University in Pittsburgh. Only when we know more about the...

    AI bests humans at mapping the moon

    Artificial intelligence is helping draw a more detailed map of the moon.

    An AI that studied lunar images to learn what craters look like has discovered thousands of new pockmarks on the moon’s surface. This program could also be used to catalog impact scars on other moons or planets, which might improve scientists’ understanding of how various objects roamed our solar system in the past...

    In the future, an AI may diagnose eye problems

    The computer will see you now.

    Artificial intelligence algorithms may soon bring the diagnostic know-how of an eye doctor to primary care offices and walk-in clinics, speeding up the detection of health problems and the start of treatment, especially in areas where specialized doctors are scarce. The first such program — trained to spot symptoms of diabetes-related vision loss in eye...

    ‘Machines That Think’ predicts the future of artificial intelligence

    Machines That ThinkToby WalshPrometheus Books, $16

    Movies and other media are full of mixed messages about the risks and rewards of building machines with minds of their own. For every manipulative automaton like Ex Machina’s Ava (SN: 5/16/15, p. 26), there’s a helpful Star Wars droid. And while some tech titans such as Elon Musk warn of the threats artificial intelligence presents...

    Ask AI: How not to kill online conversations

    A new artificial intelligence could tell whether your next post to an online forum will engage others or fall flat.

    Computer scientist Qiaozhu Mei of the University of Michigan in Ann Arbor and colleagues trained a machine-learning program on about 63,000 Reddit threads to learn what dialog-ending responses look like.

    This kind of chat-savvy computer code, described in a paper...

    AI has found an 8-planet system like ours in Kepler data

    Our solar system is no longer the sole record-holder for most known planets circling a star.

    An artificial intelligence algorithm sifted through data from the planet-hunting Kepler space telescope and discovered a previously overlooked planet orbiting Kepler 90 — making it the first star besides the sun known to host eight planets. This finding, announced in a NASA teleconference...

    AI eavesdrops on dolphins and discovers six unknown click types

    A new computer program has an ear for dolphin chatter.

    The algorithm uncovered six previously unknown types of dolphin echolocation clicks in underwater recordings from the Gulf of Mexico, researchers report online December 7 in PLOS Computational Biology. Identifying which species produce the newly discovered click varieties could help scientists better keep tabs on wild dolphin...

    New setup for image recognition AI lets a program think on its feet

    Artificial intelligence is getting some better perspective. Like a person who can read someone else’s penmanship without studying lots of handwriting samples, next-gen image recognition AI can more easily identify familiar sights in new situations.

    Made from a new type of virtual building block called capsules, these programs may cut down the enormous amount of data needed to train...
