Exponential vs Linear

Posted: April 29, 2016 at 3:13 pm

The following images show exponential and linear (respectively) increases of neighbourhood size where the maximum neighbourhood size at the top is the same (1600). They don’t seem all that aesthetically different, nor does there appear to be any smoother a transition at the horizon. The linear version is slightly more interesting (and cosmological).

I noticed that in my previous post I did not take into account the change in SOM size (20px vs 36px cells) and the horizon was positioned incorrectly (too low).
