Hi Team,

Kibana Machine Learning provides Population , Categorization and Rare options .  
We need to work on these also but we can't able to find use cases for these options.

Can anyone please explain to me where we can use these(Population , Categorization and Rare) with example or any use cases so that we can start working on this.
