When using fixed size patterns, the number of input and output values
has to match the number of input and output units in the network
respectively for training purposes. Patterns without output
activations can be defined for networks without output units (e.g. ART
networks), or for test/recall purposes for networks with output
units. It is possible, for example, to load two sets of patterns into
SNNS: A training pattern set with output values for the training of
the network, and a test pattern set without output values for
recall. The switch between the pattern sets is performed with the
button as described above.
Pattern definition files prior to V3.0 require output activations.
Networks or patterns without output are not possible
Note: All Pattern definition files prior to V3.2 now correspond to the type fixed size!
