Abstract

Neural networks normally used to model associative memory can be regarded as consisting of dissipative units (the neurons) that interact in such a way that the network itself admits a global energy or Liapunov function. The network’s global dynamics is such that the system always evolves “downhill” in the energy landscape. In most models for associative memory, the individual neurons are described as one-dimensional, dynamical systems. In the present contribution, we explore the possibility of extending the structural scheme of associative memory neural networks to more general scenarios, where the units (that is, the neurons) are modeled as multi-dimensional, dissipative systems. With that aim in mind, we advance a coupling scheme for dissipative, multi-dimensional units, that generates dynamical features akin to those required when modeling associative memory.
