Abstract

Shift invariance in associative memories is discussed. Two optical systems which exhibit shift invariance are described in detail along with computer simulations showing their effectiveness. It is shown, however, that shift invariance cannot be achieved with systems that employ only linear interconnections to store the associations without an accompanying decrease in the storage capacity equal to the number of shifted versions that are recognizable.
