NEW YORK CITY, NY- MAY 27: IBM Watson's computer housing case.
IBM's Watson computer is best known for winning Jeopardy, unaware of time constraints, while playing against humans. Some of Watson's other features are based in problem solving across many different careers. A demonstration showed how quickly Watson is able to diagnose illnesses, and provided a real life case that took doctors and nurses six days to diagnose, and only ended with the correct diagnosis because a nurse had seen the disease before. Based on symptoms input, Watson was able to correctly diagnose in minutes. The demonstration took place at IBM Watson's New York City, New York office on May 27, 2015.
