plotsomhits

Plot self-organizing map sample hits

Syntax

plotsomhits(net,inputs)


Description

plotsomhits(net,inputs) plots a SOM layer, with each neuron showing the number of input vectors that it classifies. The relative number of vectors for each neuron is shown via the size of a colored patch.

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

Examples

Plot SOM Sample Hits

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

plotsomhits(net,x)
