Soon, artificial intelligence could check your skin for cancer

A new algorithm can visually discern malignant skin lesions from less dangerous ones. A team from the Stanford Artificial Intelligence Laboratory set up a machine-learning AI to teach itself to diagnose cancer by looking at skin lesions just as a doctor would during an exam. The team tested the algorithm against 21 board-certified dermatologists, and it performed just as well as its human counterparts. "We realized it was feasible, not just to do something well, but as well as a human dermatologist," Sebastian Thrun, an adjunct professor in the Stanford Artificial Intelligence Laboratory, said in a statement. "That's when our thinking changed. That's when we said, 'Look, this is not just a class project for students, this is an opportunity to do something great for humanity.'"
