How to interpret Self Organizing Maps? A List might be better…

Self Organizing Map (SOM) is a generic method that has been applied in many applications. I spent almost 40-60 percent of my time over last three years on playing with this computational machine. Today while I was writing my PhD thesis I was trying to find a unique story line for SOM that fits well with the concept of “Pre-specific Modeling”, which is the title of my thesis. I have several technical writings to explain it in detail, but it is not convincing. As a result, I decided that may be it is better not to find a fixed way to explain SOM and maybe it should remain “pre-specific” and in this case “observer dependent”. Here, I collected a set of key words about SOM.

In principle, I can write about all of these indexes or refer to those people and papers who are focused on each of them, but now I prefer leave them as a list. Just to mention that now I am more interested in the third part of indexes which goes into analogies between SOM and other concepts.
