A learning system that is not self-stabilizing experiences a capacity catastrophe in response to an unlimited number of inputs: New learning washes away memories of prior learning if too many inputs perturb the system. The total number of input patterns that perturbs the system needs to be restricted, or the learning process itself must be shut off before the capacity catastrophe occurs.

CONT

Le rapport optimal entre le nombre d'exemples à mémoriser et le nombre de neurones se situe aux alentours de 0.14. Si l'on apprend des exemples en plus, le réseau de Hopfield présente un comportement indésirable : l'oubli catastrophique. Ainsi, un réseau peut apprendre n exemples sans problème, et les "oublier" tous dès lors que l'on souhaite lui en faire apprendre un de plus.
