I can plug the given columns into a model and get it running. But when the senior guy starts inventing new features out of the raw data, ones that suddenly make the whole thing work better, I have no idea how he sees them. I stared at the same table he did and saw nothing. Making features that actually improve the model is still beyond me.
More people experience this than they realize.
You can use given features but can't create new ones that improve the model.
If this sounds familiar, the Library can help you find the bigger picture.
