That's great. Thank you for following up so quickly. Could you point me to where I could read about this, or see an example?

I took a quick search on the documentation and I could see anything on a cursory pass:

Sorry, for the very delayed reply here.

The hyperparameter optimization feature is still in preview (though the rest of SageMaker is in general availability). We'll be putting up a page within the next week or so for you to request access.
