Top8.2 Associative Neural Networks
From now on, the terms like neural, neuron, synaptic connections, memory, association, learning, recognition, etc., will always be used in the formal sense of the present artificial neural net (ANN) theory.
Discrete model. In our starting Hopfield-like neural net model, the equation for change of neuronal activities (right in the whole state-vector
and weight-matrix J, left in their components)
or
(8.1) is coupled with the Hebb equation for synaptic connections (again, left are components of the right expression)

or
