Some problems are so complex, involving so much data of such diverse
variety, and/or in such complex relationships, that a single neural
network may not be practical. If we are using a multilayer feed-
forward network because of its run-time speed, the training time may
be too long. If we are using a probabilistic neural net to avoid long
training, or perhaps because we desire Bayesian confidences, run-time
speed may be unacceptably slow. It may even be that our problem
simply breaks down into several parts in a natural way, and we are
interested in exploiting that physical structure. These are the
principal reasons for considerin ...
