In order to compare the result after adjusting the Width, Length, Neighborhood, Initial Eta, or Cycles parameters for a Kohonen network, I need to find out the Weight vector of each cluster. Where can I get them? In the Browse window of Kohonen model, it only display the mean & sd of each variable of Input vector, but not the information of Weight vector for each cluster. By the way, I use Clementine V12.0

Thanks,

Once you have created a model (the yellow diamond) you can save/export this as PMML.  It is a form of XML and can be opened in a web browser.  Some people have created viewers to format the PMML, but a web browser (IE for example) will allow you to read all the weights and parameters easily.

If you want to read the PMML in a pretty format there are some old posts on this forum that change the PMML into HTML and text (I created some a few years ago).

If you only need the output neuron weights, then change the output field into a decimal number (see a few posts here about more information);

Thanks a lot! PMML describes the type, min/max, etc. of each variable in weight vector thoroughly.
