Spires and Full Resolution Explorations.

The images above show a few attempts to reproduce the aesthetic of the mid-resolution exploration of #5 at full resolution. As the ‘spires’ clearly overwhelm the image I wrote to the author of ANNetGPGPU. The conclusion is that the interaction of high learning rates and small neighbourhood functions lead to cases where the next BMU is very likely to be close to the previous BMU. The result is a trail of BMUs that progress across the SOM. It is unclear why they always progress at the same angle. I’m now running a test with a learning rate of 0.75 (rather than 1.0 as used previously) and I’ll continue to change learning rates and see how that looks! I may want to also revisit my previously ruled out paintings with this new insight. Now that I know these spires are an emergent result of the SOM, it’s something I should explicitly explore in the future!
