The map can be trained either automatically or manually. During automatic training the map is fed with random values at a constant rate. In manual training you can yourself select the value used for training (the input vector) by clicking on the input vector (the leftmost slider with coloured background) with the mouse or you can press the SPACE key to teach one step with a random vector. In both automatic and manual training the state of the map is shown after each step and the change between the previous and the new state is shown with the yellow areas in the map units.
Use the START/STOP button to start and stop the automatic training. The RANDOMIZE button will set the map units to random values. Use the text field to set the alpha learning rate parameter. Map units are also editable with the mouse.
More detailed information about the first demo is also available. But now, lets see that demo:
