Created by @gregatku for use in Coding Classes for Kids Unlimited, for whom I work as a Coding teacher. At a simple first level this project demonstrates some basic principles of Machine Learning or Artificial Intelligence (AI). First we train or teach the computer to remember things, and then we test out its new found "intelligence" by seeing how it reacts.
