ABSTRACT
Shift and rotation invariant pattern recognition is usu­
ally performed by first extracting invariant features from
the images and second classifying them. This poses the
problem of not only finding suitable features but also a
suitable classifier.
Here a structured invariant neural network architec­
ture (SINN) is presented that performs adaptive in­
variant feature extraction and classification simultane­
ously. The network is sparsely connected and uses
shared weight vectors. As a result features especially
