Artificial Intelligence Confronts a ‘Reproducibility’ Crisis | WIRED

A few years ago, Joelle Pineau, a computer science professor at McGill, was helping her students design a new algorithm when they fell into a rut. Her lab studies reinforcement learning, a type of artificial intelligence that’s used, among other things, to help virtual characters (“half cheetah” and “ant” are popular) teach themselves how to move about in virtual worlds. It’s a prerequisite to building autonomous robots and cars. Pineau’s students hoped to improve on another lab’s system. But first they had to rebuild it, and their design, for reasons unknown, was falling short of its promised results. Until, that is, the students tried some “creative manipulations” that didn’t appear in the other lab’s paper.

Instagram is trying to neutralize bullies before they post | Fast Company

Facebook’s Instagram said today it is launching new tools designed to combat bullying on its platform, especially among teens.

One tool, which Instagram has already begun rolling out to users, is focused on would-be bullies. It uses artificial intelligence to notify users when a comment they’ve just composed might be considered offensive. “This intervention gives people a chance to reflect and undo their comment and prevents the recipient from receiving the harmful comment notification,” says Instagram head Adam Mosseri in a blog post Monday. “From early tests of this feature, we have found that it encourages some people to undo their comment and share something less hurtful once they have had a chance to reflect,” he writes.

Will Artificial Intelligence Enhance or Hack Humanity? | WIRED

THIS WEEK, I interviewed Yuval Noah Harari, the author of three best-selling books about the history and future of our species, and Fei-Fei Li, one of the pioneers in the field of artificial intelligence. The event was hosted by the Stanford Center for Ethics and Society, the Stanford Institute for Human-Centered Artificial Intelligence, and the Stanford Humanities Center. A transcript of the event follows, and a video is posted below.

The Future of Computers Is the Mind of a Toddler | Bloomberg Business

downloadMachines contain the breadth of human knowledge, yet they have the common sense of a newborn. The problem is that computers don’t act enough like toddlers. Yann LeCun, director of artificial intelligence research at Facebook, demonstrates this by standing a pen on the table and then holding his phone in front of it. He performs a sleight of hand, and when he picks the phone up—ta-da! The pen is gone. It’s a trick that’ll elicit a gasp from any one-year-old child, but today’s cutting-edge artificial intelligence software—and most months-old babies—can’t appreciate that the disappearing act isn’t normal. “Before they’re a few months old, you play this trick on them, and they don’t care,” says LeCun, a 54-year-old father of three. “After a few months, they figure out this is not normal.”
