    Hello Thomas, thank you for your contribution!
    
    I took a brief look so some initial comments:
    
    This seems to be making changes to `MLUtils` which AFAIK is outside the scope of this issue. I would recommend you isolate changes into different issues and PRs.
    
    I also see a lot of style changes to existing code. The code style we try to follow is [this one](https://github.com/databricks/scala-style-guide), I would recommend you review that and try to follow it. 
    
    As a rule of thumb we don't make style changes to existing code, unless the existing code does not conform to the linked style. Even in that case I would recommend opening a different PR with only style changes, as it makes reviewing the core PR (which is the added code here) easier.
    
    So I'd recommend to remove the style changes you've made from this PR as well. If there is existing code that violates the linked style we can open a new PR.
