How Facebook uses artificial intelligence to explain photos for the blind

That's not great for visually impaired individuals, so Facebook has turned to artificial intelligence to improve their experience. A blind person can now hear an audio message describing a friend's photo that shows people dancing or riding bikes. To do so, Facebook's algorithm had to be taught what it was seeing. Artificial intelligence is the secret sauce behind making a project like this possible. It can do everything from translate languages, understand human speech and identify diseases.
