We tend to think of memory as storage, but a Hopfield network insists it is something more active and more fragile: a basin you fall into, a pattern that reasserts itself only because the parts agree on what they used to be.
There's purposefully a small bias built into the coded recall.
The Lambda (set to 0.35) gives each neuron a quiet pull toward the stored pattern when it isn't sure which way to flip.
But this is because human memory doesn't work in a vacuum.
We rehearse the things we want to keep. We write them out, say them to ourselves, come back to them when nothing else is asking us to.
The Lambda does the same thing for the network. A small lean toward what the pattern used to be, applied every pass, quiet enough that the recall still has to do most of the work.
Not a flaw in the system. The will to remember, written into its core.
