Connectionists: DemoGNG.js - a new simulator for competitive learning methods

[fritzke at web.de]

************* DemoGNG.js ************

A new simulator for vector-based competitive learning methods (e.g. Self-organizing Feature Map, Neural Gas, Growing Neural Gas) is available at
 
  http://www.demogng.de (cover page)

and

  http://www.demogng.de/js/demogng.html  (full-page version of the running simulator)
 

The simulator is meant as a tool for increasing the understanding of the realized models and easily comparing them to each other by running them against selected test data sets/distributions.

Models currently implemented: 
Self-organizing Feature Map, Neural Gas, Growing Neural Gas, Growing Grid, LBG, LBG-U, Hard Competive Learning, Competitive Hebbian Learning

General properties of the simulator
- visually rich presentation of the running models to increase understanding
- rapid change of model, signal distribution or simulation speed by swipe of a mouse or finger (if touch available)
- platform-independence: written in Javascript (ECMAScript 5), HTML5 and CSS
- no local installation needed (only a browser)
- links to formal descriptions of the models where available
- supports full-screen display (e.g. for classroom demonstrations)

Feedback and suggestions are welcome (fritzke at web.de)
