hi,
I followed your tutorial on clustering, and instead of getting neuron-cluster representation I get neurons plotted in sets of four of the same color (total 16 neurons). I expected 16 different colors, each color for one set of the data assigned to certain neuron.
Even if you have 16 neurons, during clustering only a subset might end up mapping some samples.
Question: How do I get neuron coordinates from this table? I don't understand how (3,1) translates to coordinate system same as the input data.
- You can use the method
winner
to get neuron coordinates. (3, 1)
is used to define the size of the map.
My advice is to use a map with a small number of neuron first (for example (3,1)
) and see if the results look like in the example, if so you can start increasing the size until it makes sense for you.
