plotsompos

Plot self-organizing map weight positions

Syntax

plotsompos(net) plotsompos(net,inputs)

Description

plotsompos(net) plots the input vectors as green dots and shows how the SOM classifies the input space by showing blue-gray dots for each neuron’s weight vector and connecting neighboring neurons with red lines.

plotsompos(net,inputs) plots the input data alongside the weights.

Examples

Plot SOM Weight Positions

x = iris_dataset;
net = selforgmap([10 10]);
net = train(net,x);
