01

Hebbian autoassociative memory stores each bipolar pattern as a stable attractor of a recurrent neural network.

02

The weight matrix is built from outer products of the stored patterns and its diagonal is cleared to avoid self-reinforcement.

03

During recall, the network iteratively updates each cell until the state converges. Noise flips cells, masking removes information, and the network fills in the missing structure from learned correlations.
