|Using the DemoGNG Applet|
After the Java applet has been launched, the DemoGNG main window appears. This window can be divided into four regions:
The first part shows the actual algorithm. To select another algorithm or restart the current, click on the pull-down menu and choose the desired algorithm.
The drawing area shows the network for the selected algorithm.
The geometric figure in the background of the area reflects the probability distribution. In every phase of the algorithm you can select a node and drag it to an arbitrary location within the drawing area. Additional information is displayed in the corners of this region:
This region contains the non-specific parameters for all algorithms. There are three kinds of interface elements: buttons, checkboxes and pull-down-menus.
Figure 7: General pull-down menus
This region shows the model specific parameters. Each time a new model is selected, the necessary parameters are displayed. For a complete description of the models and their parameters, please refer to Bernd Fritzke's tutorial, Some Competitive Learning Methods, also available as a Postscript version .
