Stability of fully asynchronous discrete-time discrete-state dynamic networks
Jacques M. Bahi, Sylvain Contassot‐Vivier · IEEE Transactions on Neural Networks · 2002
We consider networks of a large number of neurons (or units, processors, ...), whose dynamics are fully asynchronous with overlapping updating. We suppose that the neurons take a finite number of states (discrete states), and that the updating scheme is discrete in time. We make no hypotheses on the activation function of the neurons; the networks may have multiple cycles and basins. We derive conditions on the initialization of the networks, which ensures convergence to fixed points only. Application to a fully asynchronous Hopfield neural network allows us to validate our study.
