Thank you

Fabrice Clerot

the Kohonen map itself has many intresting developments, see GHSOM for instance

http://www.ifs.tuwien.ac.at/~andi/ghsom/

very handy if you are interested in quantification accuracy rather than visual interpretation, neural gas (and growing neural gas)

https://papers.nips.cc/paper/893-a-growing-neural-gas-network-learns-topologies.pdf

also pretty interesting, topoART, a "resurection" of Adaptive Resonance Theory

Hi Fabrice, those are some pretty interesting papers you have mentioned. Thank you so much. Let me have a look and get back to you.
