We fit a simple random forest supervised model to the output classes of the kmeans. This allows us to derive variable importances, as per the random forest standard method (implemented in scikit-learn).

I can see a feature with 10%, another is 5%. What is the meaning of % in variable importances?

We use the definition of variable importance in percentage from the random forest model in scikit-learn.
