The creation of the ART networks is based on just a few parameters. Although the network topology for these models is rather complex, only four parameters for ART1 and ART2, and eight parameters for ARTMAP, have to be specified.
If you have selected the , or the button in the BigNet menu, one of the windows shown in figure appears on the screen.
Figure: The BigNet windows for the ART models
Figure: Example for the generation of an ART1 network. First the BigNet (ART1) panel is shown with the specified parameters. Next you see the created net as you can see it when using an SNNS display.
The four parameters you have to specify for ART1 and ART2 are simple to choose. First you have to tell BigNet the number of units (N) the F layer consists of. Since the F layer has the same number of units, BigNet takes only the value for F.
Next the way how these N units to be displayed has to be specified. For this purpose enter the number of rows. An example for ART1 is shown in figure .
The same procedure is to be done for the F layer. Again you have to specify the number of units M for the recognition part of the F layer and the number of rows.
Pressing the button will generate a network with the specified parameters. If a network exists when pressing you will be prompted to assure that you really want to destroy the current network. A message tells you if the generation terminated successfully. Finally press the button to close the BigNet panel.
For ARTMAP things are slightly different. Since an ARTMAP network exists of two ART1 subnets (ART and ART), for both of them the parameters described above have to be specified. This is the reason, why BigNet (ARTMAP) takes eight instead of four parameters. For the MAP field the number of units and the number of rows is taken from the repective values for the F layer.
