    AI can learn real-world skills from playing StarCraft and Minecraft

    Dario Wünsch was feeling confident. The 28-year-old from Leipzig, Germany, was about to become the first professional gamer to take on the artificial intelligence program AlphaStar in the rapid-fire video game StarCraft II. Wünsch had been professionally playing StarCraft II, in which competitors command alien fleets vying for territory, for nearly a decade. No way could he lose this five-...

    Facebook data show how many people left Puerto Rico after Hurricane Maria

    Hurricane Maria sent Puerto Ricans fleeing from the island to the U.S. mainland, but population surveys to assess the size of that migration would have taken at least a year to complete. A new study suggests, however, that a Facebook tool for advertisers could provide crude, real-time estimates for how many people are moving because of a natural disaster. That could help governments design...

    Mathematicians may have found the fastest way to multiply huge numbers

    Multiplying 2 x 2 is easy. But multiplying two numbers with more than a billion digits each — that takes some serious computation.

    The multiplication technique taught in grade school may be simple, but for really big numbers, it’s too slow to be useful. Now, two mathematicians say that they’ve found the fastest way yet to multiply extremely large figures.

    The duo claim to have...

    A new algorithm could help protect planes from damaging volcanic ash

    Five to 10 minutes. That’s what it takes for superheated volcanic ash to shoot 11 kilometers into the sky — reaching altitudes at which commercial jets cruise and potentially harming their engines.

    Now scientists have developed a new algorithm that can identify and track explosive ash clouds soon after volcanoes erupt. Using satellite imagery, the program can measure the temperature,...

    Virtual avatars learned cartwheels and other stunts from videos of people

    Animated characters can learn from online tutorials, too.

    A new computer program teaches virtual avatars new skills, such as dances, acrobatic stunts and martial art moves, from YouTube videos. This kind of system, described in the November ACM Transactions on Graphics, could render more physically coordinated characters for movies and video games, or serve as a virtual training ground...

    A new computer program generates eerily realistic fake videos

    “The camera never lies” is a thing of the past.

    A new computer program can manipulate a video such that the person on-screen mirrors the movements and expressions of someone in a different video. Unlike other film-fudging software, this program can tamper with far more than facial expressions. The algorithm, to be presented August 16 at the 2018 SIGGRAPH meeting in Vancouver, also tweaks...

    Solving problems by computer just got a lot faster

    A new computer program works smarter, not harder, to solve problems faster than its predecessors.

    The algorithm is designed to find the best solution to a given problem among all possible options. Whereas other computer programs winnow down the possibilities one at a time, the new program — presented July 12 at the International Conference on Machine Learning in Stockholm — rules out...

    ‘Weird Math’ aims to connect numbers and equations to the real world

    Weird MathDavid Darling and Agnijo BanerjeeBasic Books, $27

    Weird Math sets out to “reveal the strange connections between math and everyday life.” The book fulfills that laudable goal, in part. At times, teenage math prodigy Agnijo Banerjee and his tutor, science writer David Darling, find ways to make complex math relatable, like linking chaos theory to weather forecasting and...

    Are computers better than people at predicting who will commit another crime?

    In courtrooms around the United States, computer programs give testimony that helps decide who gets locked up and who walks free.

    These algorithms are criminal recidivism predictors, which use personal information about defendants — like family and employment history — to assess that person’s likelihood of committing future crimes. Judges factor those risk ratings into verdicts on...

    ‘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...
