Setting the topology and son links of the TS-SOM

  

The first operation switches the topology of the network on or off, the second makes the same for sonlinks. If a classified data has been given, then the topology links are read from it. The classified data must include a class for each data record (neuron) when the links are specified as indexes (see the figure below).

Example (ex7.6): The example shows how several layers and links between them can be displayed.
