                              ABSTRACT

  When training neural networks by the classical backpropagation algorithm
  the whole problem to learn must be expressed by a set of inputs and
  desired outputs. However, we often have high-level knowledge about the
  learning problem. In optical character recognition (OCR), for instance,
  we know that the classification should be invariant under a set of
  transformations like rotation or translation.
  We propose a new modular classification system based on several
  autoassociative multilayer perceptrons which allows the efficient
  incorporation of such knowledge.
  Results are reported on the NIST database of upper case handwritten letters
  and compared to other approaches to the invariance problem.
