non-geographic topographic maps

75x75 map, 100 learning epoches

On radio aporee, I'm researching the possibility to create non-geographical topographic maps out of the sounds and their meta data. Since it is impossible to create an exact 2-D image of n-dimensional data, we rather try to find tendencies, proximity and clusters of similarity. Distance implies difference, but nearness does not necessarily imply resemblance. Lines and structures between areas indicate divergence, like rivers and mountains separate nearby areas in real landscapes. How meaningful these maps can be depends on the pattern we choose for comparision. Read more...
