Narrowing Down Explorations of #5 With Smaller Learning Rates

Posted: August 24, 2019 at 12:15 pm

After the insight in the previous post, I’ve explored a few variations using learning-rates smaller than 1.0. The following images are my favourites. They balance abstraction and emergent structure quite well, but are not quite there. The image on the left is insufficiently abstract where remnants of the mast in the original are still present. The wave-like structures in the lower left are very interesting and suggest quite a bit of depth and also cue the waves in the original. The image on the right shows quite good abstraction, but lacks some of that complexity in the waves, due to the larger neighbourhood (sigma = 200px).

The following images show the rest of the explorations, including highly over-abstracted versions that approach gradients. I’ve also included an attempt with a relatively high learning rate of 0.5, the highest of these explorations where the rest are 0.25 or 0.1. In that image (upper left of bottom gallery) the wave section in the lower left is very interesting, although approaches the appearance of spires; I’m not sure about the harder edges and mottled patches. That composition also shows a degree of under-organization at the smaller scale, e.g. splashes of red in the area above the bright spot.
