Chris Welty: “Inside the mind of Watson”Posted by in Uncategorized
Title: Inside the mind of Watson
Watson is a computer system capable of answering rich natural language questions and estimating its confidence in those answers at a level of the best humans at the task. On Feb 14-16, in an historic event, Watson triumphed over the best human players of all time on the American television quiz-show, Jeopardy! In this talk I will discuss how Watson works at a high level with examples from the show.
