@halsmith99 Yeah I thought the same. I did use two different models, not the lightgbm one, to perform the brute-force feature evaluation.
@master_key That is really cool to see the proportion it shares with the other feature groups!
I also forgot to mention that my original inspiration for this experiment was @mdo 's BorutaShap thread where he created the small feature set. Feature Selection with BorutaShap So I have been thinking about this idea for two years now apparently
