Unsupervised Learning in an Ensemble of Spiking Neural Networks Mediated by ITDP

Examples of random Gaussian mean placements for different NE from the manually designed initial points (black points).
The red pixels represent the outer border of the active region of the image, and the yellow pixels represent a forbidden region which is 3 pixels thick. The jittered mean points were restricted to be placed inside the inner region (including the green pixels) which is surrounded by the inner border (green).
