Kohonen advises to initialize large SOMs such that their initial organization is already similar to the expected final one to speed up convergence.

som

If a SOM is trained on data whose dimensionality is higher than that of the SOM's grid, mapping of data points into the grid becomes more and more non-monotonic, an effect called `zebra stripes' by Kohonen.
