DemoGNG, a Java applet, implements several methods related to competitive learning. It is possible to experiment with the methods using various data distributions and observe the learning process. A common terminology is used to make it easy to compare one method to the other. Thanks to the Java programming language the implementations run on a very large number of platforms without the need of compilation or local adaptation. Hopefully, the experimentation with the models will increase the intuitive understanding and make it easier to judge their particular strengths and weaknesses.
