I always liked Kohonen Networks. They're simple and fun. This is a simple 9x9 2D-to-2D Kohonen network with constant neighborhood function, trying to adjust itself to the purple training set.
Use LEFT/RIGHT to switch between training sets.
Use Z to reset the network.
Yay for machine learning on PICO-8!

Wow, AdamJ ... This is like warping reality from a simple 3x3 image.
The U though, I thought the points would only appear within the violet pixels ? They are jumping across at the top.
:-)
Well, the U shape -- yeah those outside the shape are being confused. They're getting contradicting instructions where to go and so on average they stay roughly where they are.
