Asynchronous Updating

• Since the Hopfield network is recurrent the order in which units are updated can have a significant affect on processing.
• There are two main methods.
  • synchronously, updating all units simultaneously at each timestep (c.f. chapter two) or
  • asynchronously, updating units one at a time in a random order.
• Asynchronous update is useful in symmetry breaking.
