Syntax

plotsomnd(net)


Description

plotsomnd(net) plots a SOM layer showing neurons as gray-blue patches and their direct neighbor relations with red lines. The neighbor patches are colored from black to yellow to show how close each neuron’s weight vector is to its neighbors.

This plot supports SOM networks with hextop and gridtop topologies, but not tritop or randtop.

Examples

Plot SOM Neighbor Distances

x = iris_dataset;
net = selforgmap([5 5]);
net = train(net,x);
