Snapshot
From Emergent
The Snapshot function on the Network copies a selected variable into the 'snap' variable on the Unit, which can then be viewed as a colored border around the usual unit value display, by selecting the Snap Bord button in the Network View.
Thus, you can snapshot for example the activations, display them as the colored border, and then view weights (r.wt), to compare the pattern of weights with the pattern of activations.
Basic calculations can be performed on the snapshot of values, such as finding the units that overlap between two activation states. This is done by the SnapAnd function, which computes the logical AND (actually the numerical MIN function) on the current value of the snap variable and the new variable that is being snapshot.
