Thanks Igor. This article has a lot of important information for users of all ML experience levels. For those that have had to manually code and perform these steps in the past, you can really see the time savings an auto ML option provides. I do wish we had a bit more control over what preprocessing options are used. What works best most of the time doesn't necessarily work best all the time.

Thanks! I agree with you. I know some cool features that will give you more power are on the roadmap. I am also working on the next article of this series, where I explain the performance metrics. You can use that to select a different model other than the one recommended.
