The output layer of this map consists of six nodes, A$,$ B$,$ C$,$ D$,$ E and F$,$ which are organised into a two$$dimensional lattice with neighbours connected by lines. Each of the output nodes has two inputs x$1$ and x$2($not shown on the diagram$).$ Thus, each node has two weights corresponding to these inputs: w$1$ and w$2.$ The values of the weights for all output in the SOM nodes are given in the table below:
