Plot self-organizing map weight planes
plotsomplanes(net) generates a set of subplots. Each
ith subplot shows the weights from the
ith input to the
layer’s neurons, with the most negative connections shown as blue, zero connections as black,
and the strongest positive connections as red.
The plot is only shown for layers organized in one or two dimensions.
This plot supports
SOM networks with
gridtop topologies, but not
This function can also be called with standardized plotting function arguments used by the
