Does KMeansND include normalisation by default (like KMeans2D) ?

[johnnyjohn]

Hi, 

I'm playing around with a dynamic clustering dashboard, and wanted to understand if KMeansND includes normalisation (either zscore or minmax) the same way KMeans2D does (which uses the 'norm' argument). 

Is there normalisation by default on ND? Does it need to be enabled? 

Thanks a lot
