Dynamic complex-valued associative memory with strong bias terms

Abstract

Complex-valued associative memory (CAM) can store multi-level patterns. Dynamic complex-valued associative memory (DCAM) can recall all stored patterns. The CAM stores the rotated patterns, which are typical spurious states, in addition to given training patterns. So DCAM recalls all the rotated patterns in the recall process. We introduce strong bias terms to avoid recalling the rotated patterns. By computer simulations, we can see that strong bias terms can avoid recalling the rotated patterns unlike simple bias terms. © 2011 Springer-Verlag.
