Short-Term Memory in Orthogonal Neural Networks

Disordered Systems and Neural Networks 2009-11-10 v1

Abstract

We study the ability of linear recurrent networks obeying discrete time dynamics to store long temporal sequences that are retrievable from the instantaneous state of the network. We calculate this temporal memory capacity for both distributed shift register and random orthogonal connectivity matrices. We show that the memory capacity of these networks scales with system size.
