REPLICA SYMMETRY BREAKING IN NEURAL NETWORKS WITH NON-MONOTONE ACTIVATION FUNCTION

In this paper we analyze replica symmetry breaking in attractor neural networks with non-monotone activation function. We study the non-monotone version of the Edinburgh model, which allows the control of the domains of attraction by the stability parameter K, and we compute, at one step of symmetry breaking, storage capacity and, for the strongly dilute model, the domains of attraction of the stable fixed points.
