I’m taking a ML class, this is very timely.

I hope you find my content useful! Good luck with your class.

@@DaveOnDatathank you! Actually, my class is in ML for investment strategies. Now, I know that’s a very complex topic with a lot of overlap with finance/economics, but if you have videos on feature selection and dimension reduction?

[@DaveOnData]

@DavGre - I don't have videos on feature selection/engineering, but I do cover those topics in my online course. I rarely use dimension reduction (e.g., PCA) in my ML work because I use decision tree-based techniques (e.g., the mighty random forest) that don't require it.
