I managed to batch generate 170 different SOMs with different neighbourhood sizes (default/170 to default). Unfortunately, they are not stable over time; even though they have the same initial conditions, each result has a different structure. I’m not sure if this is due to the change of neighbourhood size, or some indeterminism in the way the algorithm proceeds on the GPU. Following is a selection of the sequence with increasing neighbourhood sizes. These SOMs are rendered using the new code that renders with Gaussianoids rather than rectangles.
