Hi,
This is probably a question for IOhannes. I have been doing some experiments with the ann_som external, and I have a few questions:
- The output space is specified in two dimensions i.e. 8x8 or whatever,
but the extern only has one output. Do I assume that this maps onto the output space something like 0-7 - row 1 left-to-right ... 56-63 left-to- right?
- Do the Kohonen and Instar settings work? When I use these the output
values just cluster around the maxima. Only when I use Outstar do I get proper self organisation.

i fear that this is true (what have i thought back then ?)

hmm, they should of course work. whenever i find time, i'll investigate on this (haven't used it for ages)
