Collages with pinned percepts.

I have been working on getting large percepts to stick in the middle so they don’t push the outer edges too much. I attempted this by explicitly setting particular neurons in the middle of the SOM with features corresponding to the largest percepts. While this worked for a smaller number of training iterations (1000) it did not seem to make any difference over a large number of training iterations. The following images show the results where large percepts are scaled down to reduce the size variance. The lack of training leads to quite a few dead spots where no percepts are located. While quite dark, the black background works better for this content. I’ve included a visualization of the raw weights and a few details.
