I was reading this paper [1] about Self Organising maps, where I came across this particular passage

The neurons are organized in a 2-dimensional map. The ratio of the side lengths of the map is approximately the ratio of the two largest eigenvalues of the training data’s covariance matrix.

Does the ratio of the side lengths really influence the performance of the SOM?
