19 Questions is an online guessing game written by Will Entriken. Just think of something a common person would know about, then I ask you questions and try to guess what it is.
19 Questions learns while you play. This game is a demonstration of machine learning and a branch of math called Bayesian statistics. There is another similar game on the market 20Q by Radica which is based on neural networks, a different type of machine learning. See more notes on the entropy approach.
