to p4(X,4). All other neurons will remain inactive during this pattern input
phase.
3.1.2.2
Synchronization phase
A broadcast signal is sent to all of the neurons to mark the end of the
incoming pattern.
3.1.2.3
Bias array update
During this phase, each activated neuron contacts its adjacent nodes to
learn which nodes responded to the input. As shown in Figure 3.3, for the
input pattern P1 (XYXX), GN X(1) will update its local bias array with
the entry [GN Y(2)]. Similarly, GN Y(2) will update its bias array with the
entry [GN X(1), GN X(3)]; GN X(3) will add [GN Y(2), GN X(4)] to its
bias array; and GN X(4) will add [GN X(3)]. Each bias array entry records
