A day in the life of AI

Apple's Face ID converts your face to a set of numbers that act as your own unique identifier. This biometric portrait is not set in stone – it uses AI to track changes in your appearance, updating its model if you grow a beard, change your makeup style or get older, and it also detects whether your eyes are open and your attention is directed to your phone. Many of the iPhone's core functions are AI-enhanced. The photo app can blur backgrounds and artificially alter lighting to create the illusion of a studio photoshoot, and uses computer vision to recognise people and objects and categorise images into themes and locations. Siri uses natural language processing and machine learning to interpret your voice requests.
