The network description is stored in an ASCII file. Each module is stored in a separate file, with all modules for a particular network being grouped in a separate directory. This makes it possible to view, modify, or test individual modules using the program bpnet.
The main network description file stores the information about the overall
network structure and the names of the description files for the input layer
and for the decision module. The conventions for the names of these files are
<filename>.net for the main network decision file,
<filename>.inp for the input layer file, and
for the description of the decision network. The input layer file stores
information about the layer as a whole and also the names of the description
files for the sub-modules. The description files for the modules have the names
<no> the number of the module. The
<filename> needs to be selected such that the created
filenames are valid on the operation system which is used.
The description file for a module stores the information about the number of layers, number of inputs, the lambda value used, the type of the activation function, the number of neurons in each layer, and the connecting weights. For an example see appendix B.2.
