8. V-cell function

Each V-cell in the neocognitron evaluates outputs of C-cells (or receptor cells) from the certain connection areas from previous C-layer (or input layer).

Size of connection areas is the same for all V-cells and S-cells in one stage of the network and it is determined at construction of the network. One V-cell connection areas of size 3 by 3 cells are shown in figure 8.1.

Fig. 8.1 - Connection areas of the V-cell

V-cell output value represents average activity of cells from connection areas and it is used for inhibition of corresponding S-cell activity.

Exact specification of V-cell function is described in mathematical description of its behaviour.
