Abstract
Structured multi­layer feedforward neural networks gain more and more importance
in speech and image processing applications. The characteristic of structured neural
networks is that a­priori knowledge about the task to be performed is directly built
into their architecture by the use of nodes with shared weight vectors. Usually these
networks are trained with a modified backpropagation algorithm. However, due to the
constraints on the weight vectors it is difficult to find suitable initialization values, and
often the algorithm fails to converge.
