How artificial intelligence and deep learning secretly control what you see on Facebook

It controls what news we read, whose updates we get and what events we learn about. Its scope, power and influence extend beyond what we could imagine. So who -- or what -- decides what we see? It's literally impossible to sort the News Feed without superhuman brain power -- a problem that only AI can likely solve. At the ReWork summit in Boston on May 25, Facebook research engineer Andrew Tulloch explained how the social network is using emerging technology to prioritize what you see and better serve your needs. Facebook has been known to tweak how its system processes and ranks content in the News Feed, but it recently turned to "deep learning" -- an advanced form of artificial intelligence -- to help sift through information.
